Item Description: Bound leather ledger, 14 x 9 inches, water-damaged along the lower margin. Belonging to Lockmaster Arthur P. Finch, assigned to Lock No. 9 (Upper Ditchley Reach, Blackwater Canal). Covers the period from August 1 to September 19, 1924.

Logbook Entries: August 1924

August 1, 1924
Weather: Clear, excessively hot. Thermometer reads 88 degrees Fahrenheit at noon. Water level down four inches at the upper sill.
Traffic: Four vessels passed south, two north.

1. Barge Mary Rose (Coal, bound for Ironbridge Mills). Master: J. Higgins. Toll paid: 4s 6d.
2. Narrowboat Kingfisher (Timber, bound for Oakhaven Yards). Master: T. Small. Toll paid: 3s 2d.
3. Motor-barge Vulcan (Empty, returning north). Master: R. Vance. Toll paid: 1s 6d.
4. Barge Clara (Grain, bound for South Lock). Master: E. Davies. Toll paid: 4s 0d.

Notes: Heat is intolerable. The canal water has taken on a brownish tint near the upper culvert, likely due to low rainfall and lack of flow through the bypass weir. Young Timmy spent three hours skimming floating weeds and dead roach from the upper gate bay. Smells heavily of silt and turnip rot. Sent word to the District Superintendent regarding the water level; we shall need a flush from the northern reservoir if the heat continues, or the deeper laden coal boats will draw bottom on the lower threshold.

August 4, 1924
Weather: Stifling. No breeze. Water stagnant.
Traffic: Three vessels passed south.

Notes: A strange film has formed across the surface of the lock pit overnight. It looks oily, but when scooped up in a bucket, it leaves no residue on the fingers—only a faint yellowish slime that dries stiff like egg white. Timmy scraped out the paddle culverts this afternoon and found dozens of dead crayfish jammed behind the timber gates. None showed signs of bird-peck or hook-wound. They were simply dead, grey-white and bloated.

Bargeman Higgins came back north today on foot, looking for his dog which went missing near Ditchley Cut. He complains that the water below Lock 10 is so thick his horse refuses to drink from the towpath troughs. Told him the drought is to blame. He cursed the Canal Board and left.

August 8, 1924
Weather: Overcast, hot, close. Threat of thunder, but no rain fell.
Traffic: Five vessels passed south, one north.

Notes: A government vessel passed through at 03:00 hours without prior posting in the traffic sheet. A grey motor-launch, un-named, displaying a blue lamp at the bow. Master refused to give his name or destination, presenting instead a Special Exemption Pass stamped by the Ministry of Transport, dated July 29.

The launch was towing two narrow-gauge iron punts covered with heavy tarpaulins secured by copper wire. The craft drew nearly four feet of water, which is excessive for punts of that size. When I opened the lower paddles to empty the chamber, an unusually sharp, sweetish vapor rose from the churning water. It put me in mind of the hospital tents behind the lines at Ypres—chloroform mixed with marsh gas. My eyes watered fiercely, and Timmy had a fit of coughing that lasted twenty minutes. I asked the launch master what was under those canvas sheets. He told me to stick to my winches and mind my own skin.

[Note added in margin in red ink, dated Sept 22, 1924, by Dr. H. Hargrove: "Crucial entry. Note the date. Cross-reference with Ministry Shipping Register for late July. Check manifest of vessel 'Pluto' or similar unregistered launches."]

August 11, 1924
Weather: Bright sun, muggy.
Traffic: Two vessels south, two north.

Notes: Timmy did not report for duty this morning at six. I went down to his cottage by the bridge and found him in bed with his boots on. His mother says he took a chill last night, though the bedroom was like an oven. He was burning to the touch, skin dry as charcoal, complaining of a terrible weight in his legs and a ringing in his ears like brass bells. His throat was so raw he could barely swallow boiled milk.

I had to manage the lock levers myself all day. Heavy work for a man of my age without a lad to throw the balance beams. The lower gate is binding on the heel-post; the wood seems swollen, despite the low water.

August 14, 1924
Weather: Hazy heat.
Traffic: Four vessels south.

Notes: Timmy is no better. Dr. Hargrove came down from the village on his bicycle to examine him. The doctor says it looks like an unusual form of gastric fever or summer influenza, though he seemed puzzled by the blue-black spots that have appeared around the lad’s wrists and behind his ears. Hargrove asked if Timmy had been drinking river water. I told him we both drink from the deep brick well behind the lock-house, which is fifty yards back from the canal bank and fed by the hill spring. The doctor pulled a sample of water from the well in a clear glass bottle, held it to the sun, and said it seemed pure enough, though he advised boiling it regardless.

Water in the lock is lower still. Black mud showing on the sloping banks. The smell is dreadful now—like copper pennies and rotten meat.

August 18, 1924
Weather: Still, oppressive.
Traffic: One vessel south, three north.

Notes: Bargeman Small brought the Kingfisher back up from the lower basin. He had to leave his wife behind at the apothecary’s in Ditchley. He says she was taken ill two nights ago while they were tied up near the old lime kilns—shivering fits, high fever, and vomiting blood-stained phlegm. Small was in a foul temper. He claims the canal water is poisoned by the chemical works six miles upstream at Oakhaven.

I told him the chemical plant was shut down three years ago after the war contracts ended, but he insists someone is dumping night-soil or industrial wash into the cut under cover of dark. He showed me a towing line he had pulled from the water near Ditchley; the hemp was bleached white and fell apart in my hands like wet tissue paper.

August 22, 1924
Weather: Hot. High clouds.
Traffic: No commercial traffic today.

Notes: The silence on the canal is growing eerie. Normally we have six or seven boats a day carrying stone, coal, or timber for the town, but word seems to have spread among the bargemen that something is wrong with the Ditchley Reach. Two boat families have tied up at the turn-hole three miles north and refuse to proceed down toward Lock 9.

Timmy’s mother came to the lock-house at noon, weeping. The lad is out of his head with fever now, talking to people who aren’t there and clawing at his chest as if his skin were on fire. Dr. Hargrove visited again and put a quarantine card on their door, though he won't say what disease he suspects. He took another sample of canal water, this time from the deep lock bay itself, using a brass sampling canister he lowered to the bottom.

When he drew the canister up, the metal was tarnished black, as if it had been held over a sulfur stove. Hargrove looked very grave. He warned me not to touch the lock water with my bare hands and to wear leather gauntlets when handling the paddle ropes.

August 25, 1924
Weather: Unchanged. Hot and airless.
Traffic: One vessel north.

Notes: The motor-launch returned from the south at 02:15 hours. It was empty this time, riding high in the water, running without lights. I refused to raise the sluice gates until the master showed his pass. He came ashore, and I saw his face by my hurricane lantern. He looked dreadful—eyes sunken, cheeks yellow as lard, skin sweating profusely despite the cool of the night air.

He didn't argue with me. He tossed a five-shilling piece onto the balance beam and told me to hurry, saying, "Open the culverts, old man, or there’ll be army boots on this towpath before the week is out."

I opened the gates and let him through. As the launch moved north into the darkness, I noticed that the wake it left wasn't white foam, but a stiff, yellowish scum that stuck to the masonry walls like fat.

My hands have begun to ache in the joints. A dull, throbbing pain in my knuckles and wrists. I put it down to turning the lock winches alone these past ten days.

Logbook Entries: September 1924

September 1, 1924
Weather: Heavy haze. Sky looks like lead.
Traffic: None.

Notes: Timmy died this morning at four o'clock.

His mother sent for me, but by the time I reached the cottage, the boy was gone. His body had turned a dark, bruised violet color from the hips to the throat. Dr. Hargrove arrived at seven with two constables from Oakhaven. They sealed the cottage immediately. The doctor would not permit a regular wake or viewing; he ordered the body wrapped in oilcloth soaked in carbolic acid and buried before noon in the churchyard at Ditchley.

The constables have posted a notice on the bridge: CANAL NAVIGATION TEMPORARILY RESTRICTED BY ORDER OF THE SANITARY AUTHORITY.

I asked Constable Wilkins what this was all about. He said there’s sickness down in Ditchley village—forty people down with high fever, three dead since Friday. They say it came up from the river marshes, but everyone knows the river doesn't run within two miles of the Cut.

September 4, 1924
Weather: Wind from the south, carrying a sharp, metallic odor.
Traffic: Official vessels only.

Notes: A steam tug belonging to the Canal Company arrived from Oakhaven at nine this morning, carrying Mr. Arbuthnot, the Chief Engineer, and two gentlemen in city clothes wearing grey bowler hats. They had a crate of glass bottles and spent two hours taking water samples from the lock chamber, the upper sill, and the deep culverts.

I offered Mr. Arbuthnot the logbook to sign, as is standard practice for visiting officials. He waved it away impatiently.

"Finch," he said to me, "have you seen any unauthorized dumping along this reach?"
"None," I replied, "except for that government motor-launch that passed through on the eighth and twenty-fifth of last month."

One of the city gentlemen—a thin man with gold-rimmed spectacles—immediately took out a notebook and asked me to describe the launch, its crew, and its cargo. When I mentioned the iron punts and the smell like bad sweet spirits, Mr. Arbuthnot interrupted him, saying, "That's enough of that. The lockkeeper is obviously mistaking ordinary weed-clearing craft for something else."

They took their samples, boarded the tug, and turned back north toward Oakhaven without giving me any further instructions.

My wrists are much worse today. The joints are swollen, and I have developed a dry, hacking cough that rattles in my ribs.

September 8, 1924
Weather: Dense fog rising from the canal at dawn, lingering until mid-afternoon.
Traffic: None.

Notes: The canal is completely dead now. No barges. No foot traffic on the towpath. The Company has erected wooden barricades across the path at Lock 8 below and Lock 10 above. A county policeman is stationed at the road bridge.

Dr. Hargrove came by on foot late this afternoon. He looked exhausted, his collar unbuttoned, his boots coated in dry grey mud. He sat on the bench outside my kitchen door and drank a glass of tea I brewed for him.

He tells me the hospital at Oakhaven is full. They have cleared out the old workhouse ward to hold the overflow. Over eighty cases now. The symptoms are always the same: sudden high fever, dark blotches under the skin, intense joint pain, followed on the fourth or fifth day by black vomit and heart collapse.

"It isn't cholera," he told me, staring at his boots. "It isn't typhoid, and it isn't typhus. It acts like a poison, Finch, but it spreads like an infection."

I showed him my wrists. He took my hand, turned it over, and pushed his thumb firmly against the skin over my pulse. A deep blue spot, the size of a sixpence, remained where his thumb had been, refusing to turn white. He did not say a word, but pulled a small brown bottle of quinine pills from his bag and set it on the table.

"Take two every four hours," he said. "And Finch—do not drink from your well again. I’ll send a water cart down from the village tomorrow if I can spare a horse."

September 12, 1924
Weather: Drizzle, but the heat remains trapped under the clouds.
Traffic: None.

Notes: The water cart never came. I had to walk up to the spring on the hill with two buckets to fetch drinking water. The walk back took me an hour; my knees felt like crushed gravel, and my head was spinning so terribly I had to sit on the grass three times to keep from swooning.

While sitting by the hedge near the top lock, I looked down at the Ditchley Cut. In the grey light, the water was not moving at all. It looked thick, like tallow or cold broth. Along the margins, where the reeds usually grow, every stalk of bullrush has turned black and bent double, as if scorched by a flame.

I found three sheep lying dead in the ditch behind the lock-house. They belonged to Farmer Giles. No marks on them. Blood was trickling slow and black from their nostrils.

September 15, 1924
Weather: Heavy rain at last, but it brings no relief. The rain seems to pull the bad smell down from the sky.
Traffic: None.

Notes: I cannot keep my food down today. Tried to eat a piece of dry bread, but it tasted like iron rust.

A military lorry arrived at the bridge at three o'clock. Six soldiers in khaki coats with red armbands got out and set up a canvas tent across the road. They are armed with rifles. One of them walked down to the lock and told me I was not to leave the lock-house precinct under any circumstances.

I showed him my Lockmaster's Warrant, signed by the Board of Governors. He laughed and said, "That paper isn't worth a spit now, old man. This whole valley is under military cordon."

I asked him what was happening down in the capital. He told me to shut my door and stay inside.

The heat in my blood is mounting. When I close my eyes, I hear the sound of the lock paddles opening, over and over—that rushing, gurgling sound of high water filling the chamber. But when I look out the window, the lock is empty, and the timber gates are bare, rotting ash.

September 18, 1924
Weather: Unknown.
Traffic: None.

Notes: Dr. Hargrove came to the door last night. Or perhaps it was this morning. I cannot keep the time straight anymore. The clock on the mantelpiece has stopped, and my hands shake too badly to wind the key.

He didn't come inside. He spoke through the window glass. He said they found where the motor-launch was going. There is a disused stone quarry two miles up the Ditchley Feeder canal—the old Blackwood Quarry that was flooded in '08. He says someone built a timber pier inside the quarry gates and has been sinking iron drums into eighty feet of water.

He was shouting through the glass, but his voice sounded tiny, like he was speaking down a long drainpipe. He said the drums are leaking. He said the metal is corroding in the acidic water of the quarry, and whatever was put inside them is coming down the feeder stream straight into Lock 9.

"It's not a bug, Finch!" he kept shouting. "It's not a bacterium! It’s something else!"

I couldn't answer him. My tongue feels swollen, like a lump of wet leather filling my mouth. I tried to write this down while sitting at the kitchen table, but the pen keeps slipping through my fingers.

September 19, 1924
Weather: Dark.

Notes: Water rising in the pit. Can hear the beams groaning. Must go out and turn the capstan. If the upper gate gives way, the whole reach will come down.

Timmy is standing by the balance beam. He is wearing his oilskins. He says the water is cold today.

Hands black.

Can't reach the key.

Item Description: Folder labeled "Lock 14 Field Reports & Telegraphic Dispatches (Urgent)." Contains official correspondence, hand-written telegraph transcripts, and field inspection memoranda from Assistant Inspector Marcus E. Vance, stationed at Lock 14 (Lower Ditchley Reach). Covering August 28 to September 16, 1924.

Official Field Memorandum No. 114

To: Chief Engineer Arthur Arbuthnot, Central Office, Oakhaven
From: Assistant Inspector Marcus E. Vance, Field Operations, Lock 14
Date: August 28, 1924
Subject: Abnormal Hydrological Conditions and Vessel Congestion at Lock 14

Sir,

I am writing this report under conditions of considerable strain from the observation station at Lock 14. The situation on the Lower Ditchley Reach has deteriorated markedly over the past forty-eight hours, and I feel it my duty to bring several matters to your immediate attention before commercial traffic halts entirely.

As of six o’clock this morning, fourteen commercial vessels lie moored between the lower sill of Lock 14 and the turn-hole at Blackwood Marsh. The bargemen are in an ugly mood. A delegation led by Master Thomas Small of the Kingfisher presented themselves at my quarters at dawn, demanding to know why water levels in the lower cut have dropped by eleven inches since Tuesday despite the lack of any deliberate draw-off at the weir.

Upon conducting an inspection of the masonry gates at Lock 14, I observed a phenomenon similar to that reported informally by Lockmaster Finch at Lock 9 earlier this month. The water within the chamber is not merely low; it has acquired an extraordinarily heavy consistency, resembling thick linseed oil or lukewarm gelatine. When the paddle sluices are lifted, the water does not rush through the culverts with the customary turbulence; rather, it pours in a sluggish, silent mass, accompanied by a thick white froth that settles along the stone quoins and refuses to dissipate.

Furthermore, the smell rising from the lower lock pit is overpowering. It is not the familiar stink of summer stagnation or decomposing pond-weed. It carries a distinct, sharp metallic tang—reminiscent of nitric wash or the pickling vats at the steel mills—coupled with a cloying, sickly sweetness that catches in the back of the throat. Two of my junior lock-hands, Jenkins and Miller, were obliged to abandon their posts on the balance beams at mid-day after suffering bouts of severe nausea and violent nosebleeds.

I questioned Master Small regarding his passage down from the upper reach. He states that while passing the abandoned stone quarry near Ditchley Feeder three nights ago, his crew observed several heavy timber flats moored in the mouth of the disused cutting. He claims that men operating hand-winches were lowering large, cylindrical metal containers directly into the submerged quarry pit. When his mate hailed the craft, a man on the shore warned them off with a shotgun.

I reminded Small that the old quarry is private property leased under wartime emergency provisions and advised him against spreading alarmist rumors among the boat families. However, given the severe drop in water quality and the unannounced movement of dark-hulled motor launches past Lock 14 during the small hours of the morning, I must respectfully request an immediate sanitary inspection of the feeder channel.

I remain, sir, your obedient servant,

Marcus E. Vance
Assistant Inspector, District 4

Official Field Memorandum No. 119

To: Chief Engineer Arthur Arbuthnot, Central Office, Oakhaven
From: Assistant Inspector Marcus E. Vance, Field Operations, Lock 14
Date: September 3, 1924
Subject: Containment Measures and Interruption of Public Way

Sir,

I have received your short note of September 1st delivered by the company courier. While I take note of your instruction to "maintain normal traffic flow and discourage foolish hysteria among the floating population," I must inform you that normal operations at Lock 14 are no longer possible.

At three o'clock yesterday afternoon, the barge Clara, laden with fifty tons of grain bound for the southern mills, grounded heavily upon the upper sill of Lock 14. The draft of the vessel should have allowed at least fourteen inches of clearance under normal summer conditions. However, the accumulation of an unknown, greyish sludge upon the masonry floor of the lock chamber has effectively reduced the depth of the channel.

When the master of the Clara, Mr. E. Davies, attempted to pole his craft off the masonry, his ash pole snapped in two. The lower submerged half of the timber had turned black and soft, as if plunged into concentrated vitriol. Upon withdrawing the broken stump, Mr. Davies accidentally splashed a quantity of the lock water onto his exposed calf. Within two hours, the skin of his leg had raised into massive, dark fluid-filled blisters. He was conveyed to the cottage at Lock 14 in severe agony and is presently unable to stand.

The bargemen have now formed a blockade across the towpath. They have tied three heavy coal flats broadside across the cut above Lock 14, completely sealing the navigation. They refuse to allow any craft—including official company vessels—to pass north or south until a qualified medical officer examines the water and certifies it safe.

I must also record my profound concern regarding the arrival at midnight of a squad of six armed men wearing grey oilskin coats and broad-brimmed hats, claiming to represent the "Department of Special Supplies." They arrived on foot via the woodland track from Blackwood, bypassing the main road. Their leader, a man who refused to state his name or produce written credentials beyond a stamped metal token, demanded that I immediately open the bypass culverts to flush the contents of Lock 14 into the lower marshlands.

I refused to comply with this order without a signed requisition from your office. The individual in question informed me that "administrative technicalities are suspended" and implied that my continued employment—and personal liberty—would be endangered should I obstruct their work. They proceeded to force the paddle winches open by hand using iron crowbars, damaging the bevel gears on the starboard sluice in the process.

The discharge of water into the marsh took nearly four hours. The vapor rising from the turbulent outflow was so intense that it turned the lead paint on the lock-house window frames from white to a dull greyish-black before dawn.

I urge you, sir, to come to Lock 14 in person. The local authorities in Ditchley are panicking, and Dr. Hargrove is overwhelmed by the number of sick in the lower village. This is no longer a mere navigation obstruction; it is a catastrophe of the first magnitude.

Private Journal Entry / Field Notes of Assistant Inspector Vance

(Recovered from the lock-house desk at Lock 14; handwritten in an exercise book)

September 9, 1924
The silence down here is far worse than the noise of the angry bargemen. The boat families have all fled. They abandoned their barges tied to the bank, leaving their coal and timber behind, and took to the roads on foot with whatever they could carry on their backs. The constabulary turned back several families at the Ditchley crossroads, forcing them into the pine woods near the old brickworks. I can hear the children crying in the trees when the wind shifts from the west.

Jenkins died at three this morning in my spare room. I could do nothing for him. His tongue was swollen so large he could not swallow water, even had I dared to offer him any from the house well. His body has taken on that same horrible dark violet hue that Finch described in his last note from Lock 9.

I walked down to the lower gates at noon today wearing a wet neckerchief over my mouth and nose. The bed of the canal below Lock 14 is almost dry now, owing to the damaged paddles allowing the water to drain off into the marsh.

What I saw in the mud fills me with cold terror.

It is not silt. The bottom of the cut is covered in a thick layer of greyish-white sludge, nearly two feet deep, that boils and bubbles slowly with tiny gas pockets even in the absence of heat. Stranded in this sludge are thousands of fish—pike, perch, bream—all completely stripped of their scales, their flesh reduced to a soft, jelly-like consistency.

More disturbing still are the iron drums.

About two hundred yards above the lock sill, where the Ditchley Feeder joins the main canal, the low water has exposed three large iron cylinders lodged in the mud. They are painted with dark red lead, but the metal has pitted severely, eating away into jagged holes along the seams. From these holes, a thick, yellow-brown paste is oozing directly into the stream.

Printed on the rusted side of one drum, clear enough to read through my field glass, are the words: PROPERTY OF WAR OFFICE - EXPERIMENTAL SANITARY SECTION - SUBSTANCE 14-B - TOXIC - DO NOT IMMERSE NEAR DRINKING WATERS.

My God. It was never an industrial accident. They knew what was in those punts.

My wrists have begun to throb terribly tonight. I am writing this by candlelight, but the flame seems to have a greenish halo around it. I must try to get this ledger to Dr. Hargrove before the guards at the road bridge stop all foot traffic.

Destination: Headquarters, 12th Infantry Brigade, Oakhaven
Date: September 12, 1924 (09:10 AM)

CAPTAIN FORSTER TO BRIGADE MAJOR. CIVILIAN MARCUS VANCE APPREHENDED ATTEMPTING TO PASS CORDON AT DITCHLEY ROAD CUTTING WITH CONTAINERS OF CANAL SILT AND LEATHER-BOUND LEDGERS. SUBJECT EXHIBITS ADVANCED SYMPTOMS OF CONTAGION: SEVERE OCULAR INFLAMMATION, CUTANEOUS BLOTCHING, DISORIENTATION. SUBJECT SUBJECTED TO IMMEDIATE QUARANTINE AT TEMPORARY DETENTION HUT BEHIND LOCK 14. PROPERTY SEIZED AND STORED IN SEALED ZINC CASE ACCORDING TO PROTOCOL EPIDEMIC-9. ADVISE DISPOSITION OF SUBJECT AND DOCUMENTS.

Official Memorandum No. 128 (Final)

To: Ministry of Transport, Special Committee on Waterway Contagion
From: Dr. H. Hargrove, M.D., Medical Officer of Health (Acting)
Date: September 16, 1924
Subject: Condition of Lock 14 and Surrounding Precincts

Gentlemen,

I am submitting this report under protest, using the courier provided by the military cordon, as all civilian postal services through Ditchley have been suspended by executive decree.

On September 14th, accompanied by Captain Forster of the 12th Infantry Brigade, I entered the lock-house at Lock 14 to inspect the premises and recover the official station logs.

Assistant Inspector Marcus E. Vance was found in a state of terminal collapse in the lock-house cellar, where he appears to have dragged himself to escape the heat of the upper rooms. He was incapable of coherent speech, though he pointed repeatedly toward the feeder stream and the disused quarry road. He succumbed to respiratory arrest at approximately 14:30 hours.

The conditions at Lock 14 are significantly more advanced than those observed at Lock 9 earlier this month. The chemical agent—for I can no longer, in good conscience, term this an infectious biological disease—has completely saturated the water table throughout the lower reach. The shallow wells supplying the lock-cottages, the road-side taverns, and three tenant farms within a half-mile radius of the canal are all heavily contaminated with soluble inorganic sulfur compounds and a complex organic compound that reacts violently with organic tissue.

The mortality rate among those living within two hundred yards of the canal towpath now exceeds sixty percent. The nature of the symptoms—specifically the rapid destruction of vascular tissue, the blue-black petechial hemorrhages, and the profound necrosis of the pulmonary membranes—indicates acute exposure to a concentrated corrosive toxin acting both by contact and through the inhalation of off-gassed vapors.

I have examined the iron drums exposed at the mouth of the Ditchley Feeder. They are identical to the military disposal containers utilized during the late European conflict for the encasement of chemical manufacturing residues. It is manifest that an attempt was made during late July and early August to dispose of several hundred such containers by sinking them in the deep, water-filled pits of Blackwood Quarry.

The acidic nature of the quarry water, combined with the structural failure of the poorly welded seams, has resulted in a wholesale rupture of these vessels. The contents are now leaching systematically down the feeder canal into the main line of the Blackwater Canal, transforming a twelve-mile stretch of navigable water into a lethal conduit.

I must insist upon the following immediate measures:

1. The total evacuation of all civilian populations within two miles of the canal between Lock 8 and Lock 16.
2. The construction of heavy timber and clay dams across the Ditchley Feeder to prevent further outflow from Blackwood Quarry.
3. The immediate disclosure by the War Office and the Ministry of Transport of the precise chemical formula of "Substance 14-B," so that an effective neutralizing agent or medical countermeasure may be devised.

If these measures are not taken within forty-eight hours, the toxin will reach the main river junction at Oakhaven, jeopardizing the drinking water supply of thirty thousand people.

I am placing this dispatch, together with Inspector Vance’s recovered notes, into the hands of the military escort. God help this valley if you choose to ignore it.

Respectfully yours,

H. Hargrove, M.D.
Medical Officer of Health, Ditchley District

Archival Closing Memorandum

Document Ref: PRO/CAN-1924-09-015
Filing Officer: Colonel R. L. Danvers, Director of Military Intelligence, Branch 6
Date: October 22, 1924
