At the War Office in London, in the autumn of 1914, I met Captain Sydney Rowland of the staff of the Lister Institute. He was a man who had made a reputation in the scientific world and had just been authorized by the British War Office to purchase a huge motor caravan to be equipped as a mobile laboratory. The caravan had been built originally by a wealthy automobile manufacturer at a cost of 5,000 pounds, and had been completely equipped for living in while touring the country. It even had a little kitchen, and the whole affair was lined with aluminium. Tiring of it, the builder had sold it to a bookmaker who used it for less legitimate purposes.

Captain Rowland had heard of this machine and finally located and purchased it. All the expensive interior was torn out and replaced with work benches and sinks, while shelves and racks were provided for glassware and apparatus. It was a beautifully equipped, compact machine, and he was justly proud of it.

When he took it over to France he drove it up to the army area himself, and told me that as he approached the front through villages and towns at the rate of twenty-five miles an hour he had an absolutely unimpeded road. After one look at this huge affair, which was about the size of one of our large moving vans, bearing down on them like a runaway house, people fled or took to the side roads. Captain Rowland described with great glee the sensation it had caused, and his enjoyment of that drive.

That was the first mobile laboratory, the beginning of the field laboratories and the model upon which all others were constructed. The list of equipment prepared and used by Captain Rowland was also used as the basis for the requirements for all mobile laboratories subsequently equipped. A second bacteriological laboratory and two hygiene laboratories were sent out before permission was obtained from the Director of the Canadian Medical Service, to send out a Canadian laboratory. For some unexplained reason the Canadian Government refused the necessary funds for the chassis so that we were compelled to pack our equipment in twenty-four numbered cases, all of which could be carried on a three-ton motor lorry. I had discovered that the officers in charge of these laboratories at the front had already found them too small to work in comfortably, and had removed and placed the equipment in some convenient house, using the lorry merely to carry their equipment. We were able to carry twice as complete an equipment, costing altogether less than $2,000 in a borrowed lorry, and saved the cost of $10,000 for the motor chassis.

When the first Canadian Division went to France, No. 1 Canadian General Hospital had been left behind on Salisbury Plain, to take care of the sick. It had been decided that I was to go to France in command of the Canadian Mobile Laboratory, and that I should take with me two officers and several men from the staff of that hospital. The Lozier car which had been given me by the Canadian Government was also to go as part of the equipment. After working in the office of the Director of Medical Services for a couple of weeks straightening out the records in regard to typhoid inoculation, and cerebro-spinal meningitis, and in purchasing the necessary equipment, I received word that the laboratory was to go to the front immediately. The Surgeon-General accordingly made all the necessary arrangements, and left for France, while I went down to Bulford to wait for the expected telegram which was to speed us on our way.

We waited over three weeks for the message, growing more and more desperate every day. Finally we went up to London and found that somebody had made a mistake and that we were supposed to be in France long ago. We were instructed to leave on the second day following.

The men were all greatly excited at the good news. We had a farewell dinner that night at the mess, which assumed a somewhat convivial character, and when I left to drive two visitors into Salisbury, the hospital dentist was making a rambling, tearful plea to a few hilarious auditors, on behalf of Ireland, while the great majority were paying no more attention to him than if he did not exist.

Next morning with our equipment, men and car, we set out for Southampton, amid the envious farewells of our brother officers, whose call had not yet come. Everything was loaded on board the transport at noon, and late in the afternoon we left for Havre, accompanied by two torpedo boat destroyers.
