“You needn’t be. I’m going down to the army post on Governor’s Island first to be vaccinated against typhoid. Then I am going to wait a few hours till it takes effect before going. It’s the only place in the city where one can be inoculated against it, so far as I know. While three inoculations are really best, I understand that one is sufficient for ordinary protection, and that is all we shall need, if any.”
“You’re sure of it?”
“Almost positive.”
“Very well, Craig. I’ll go.”
Down at the army post the next morning we had no difficulty in being inoculated against the disease. The work of immunising our army was going on at that time, and several thousands of soldiers in various parts of the country had already been vaccinated, with the best of results. “Do many civilians come over to be vaccinated?” asked Craig of Major Carroll, the surgeon in charge.
“Not many, for very few have heard of it,” he replied.
“I suppose you keep a record of them.”
“Only their names—we can’t follow them up outside the army, to see how it works. Still, when they come to us as you and Mr. Jameson have done we are perfectly willing to vaccinate them. The Army Medical Corps takes the position that if it is good for the army it is good for civil life, and as long as only a few civilians apply we are perfectly willing to do it for a fee covering the cost.”
“And would you let me see the list?”
“Certainly. You may look it over in a moment.”
Kennedy glanced hurriedly through the short list of names, pulled out his notebook, made an entry, and handed the list back. “Thank you, Major.”
Bisbee Hall was a splendid place set in the heart of a great park whose area was measured by square miles rather than by acres. But Craig did not propose to stay there, for he arranged for accommodations in a near-by town, where we were to take our meals also. It was late when we arrived, and we spent a restless night, for the inoculation “took.” It wasn’t any worse than a light attack of the grippe, and in the morning we were both all right again, after the passing of what is called the “negative phase.” I, for one, felt much safer.
The town was very much excited over the epidemic at the hall, and if I had been wondering why Craig wanted me along my wonder was soon set at rest. He had me scouring the town and country looking up every case or rumour of typhoid for miles around. I made the local weekly paper my headquarters, and the editor was very obliging. He let me read all his news letters from his local correspondent at every crossroads. I waded through accounts of new calves and colts, new fences and barns, who “Sundayed” with his brother, etc., and soon had a list of all the cases in that part of the country. It was not a long one, but it was scattered. After I had traced them out, following Kennedy’s instructions, they showed nothing, except that they were unrelated to the epidemic at the hall.
Meanwhile, Kennedy was very busy there. He had a microscope and slides and test-tubes and chemicals for testing things, and I don’t know what all, for there was not time to initiate me into all the mysteries. He tested the water from the various driven wells and in the water-tank, and the milk from the cows;—he tried to find out what food had come in from outside, though there was practically none, for the hall was self-supporting. There was no stone he left unturned.
When I rejoined him that night he was clearly perplexed. I don’t think my report decreased his perplexity, either.
“There is only one thing left as far as I have been able to discover after one day’s work,” he said, after we had gone over our activities for the day. “Jim Bisbee never drank the water from his own wells. He always drank a bottled water shipped down from a camp of his in New York State, where he had a remarkable mountain spring. I tested a number of the full bottles at the hall, but they were perfectly pure. There wasn’t a trace of the bacillus typhosus in any of them. Then it occurred to me that, after all, that was not the thing to do. I should test the empty ones. But there weren’t any empty ones. They told me they had all been taken down to the freight station yesterday to be shipped back to the camp. I hope they haven’t gone yet. Let’s drive around and see if they are there.”
The freight-master was just leaving, but when he learned we were from the hall he consented to let us examine the bottles. They were corked and in wooden cases, which protected them perfectly. By the light of the station lamps and the aid of a pocket-lens, Kennedy examined them on the outside and satisfied himself that after being replaced in the wooden cases the bottles themselves had not been handled.
“Will you let me borrow some of these bottles tonight” he asked the agent. “I’ll give you my word that they will be returned safely tomorrow. If necessary, I’ll get an order for them.”
The station-agent reluctantly yielded; especially as a small green banknote figured in the transaction. Craig and I tenderly lifted the big bottles in their cases into our trap and drove back to our rooms in the hotel. It quite excited the hangers-on to see us drive up with a lot of empty five-gallon bottles and carry them upstairs, but I had long ago given up having any fear of public opinion in carrying out anything Craig wanted.
In our room we worked far into the night. Craig carefully swabbed out the bottom and sides of each bottle by inserting a little piece of cotton on the end of a long wire. Then he squeezed the water out of the cotton swab on small glass slides coated with agar-agar, or Japanese seaweed, a medium in which germ-cultures multiply rapidly. He put the slides away in a little oven with an alcohol-lamp which he had brought along, leaving them to remain overnight at blood heat.
I had noticed all this time that he was very particular not to touch any of the bottles on the outside. As for me, I wouldn’t have touched them for the world. In fact, I was getting so I hesitated to touch anything. I was almost afraid to breathe, though I knew there was no harm in that. However, it was not danger of infection in touching the bottles that made Craig so careful. He had noted, in the dim light of the station lamps, what seemed to be finger-marks on the bottles, and they had interested him, in fact, had decided him on a further investigation of the bottles.
“I am now going to bring out these very faint fingerprints on the bottles,” remarked Craig, proceeding with his examination in the better light of our room. “Here is some powder known to chemists as ‘grey powder’—mercury and chalk. I sprinkle it over the faint markings, so, and then I brush it off with a camel’s-hair brush lightly. That brings out the imprint much more clearly, as you can see. For instance, if you place your dry thumb on a piece of white paper you leave no visible impression. If grey powder is sprinkled over the spot and then brushed off a distinct impression is seen. If the impression of the fingers is left on something soft, like wax, it is often best to use printers’ ink to bring out the ridges and patterns of the finger-marks. And so on for various materials. Quite a science has been built up around fingerprints.
“I wish I had that enlarging camera which I have in my laboratory. However, my ordinary camera will do, for all I want is to preserve a record of these marks, and I can enlarge the photographs later. In the morning I will photograph these marks and you can do the developing of the films. Tonight we’ll improvise the bathroom as a dark-room and get everything ready so that we can start in bright and early.”
We were, indeed, up early. One never has difficulty in getting up early in the country: it is so noisy, at least to a city-bred man. City noise at five A.M. is sepulchral silence compared with bucolic activity at that hour.
There were a dozen negatives which I set about developing after Craig had used up all our films. Meanwhile, he busied himself adjusting his microscope and test-tubes and getting the agar slides ready for examination.
Shirt-sleeves rolled up, I was deeply immersed in my work when I heard a shout in the next room, and the bathroom door flew open.
“Confound you, Kennedy, do you want to ruin these films!” I cried.
He shut the door with a bang. “Hurrah, Walter!” he exclaimed. “I think I have it, at last. I have just found some most promising colonies
