A peculiar affliction, first noticed during this war, is what is known as "trench feet." Where men are required to remain for long periods standing in cold water and unable to move about to any great extent, the circulation of blood in the lower limbs becomes sluggish and, eventually, stops. The result appears to be exactly the same as that caused by severe frost-bite; in fact it _is_ freezing without frost, (I don't know why not, if you can cook with a fireless cooker), and, in severe cases, amputation is necessary. While the Imperial troops on our flank suffered considerably from this dreaded affliction, we had but few cases, although our position was infinitely worse than theirs, we being in lower ground. Probably the average Canadian is better able to stand the cold and wet than the native-born Briton. We had but one case in the Machine Gun Section and that was not severe. As a preventive measure, whale oil was issued with positive orders that every man must, at some time during each twenty-four hours, remove his shoes and socks and rub his feet with this oil. I never did think the oil was anything but just an excuse to make the men rub as that in itself would be sufficient to restore the circulation. At any rate, when the oil gave out, we still kept up the rubbing game and there was no noticeable change in the result. Another hitherto unknown disease which developed during that season was what is commonly known as "trench fever." The victim's temperature runs up around one hundred and three and he is affected with lassitude and general debility and it requires from three weeks to a month in hospital to put him in shape for duty. The medical officers use a Greek name for this fever, which, translated, means, "a fever of unknown origin" but the colloquial designation is "G. O. K.," (God only knows). It is rarely, if ever, fatal. I never heard of any one dying of it. Then there is a sort of skin affection; a "rash," which is said to be caused by eating so much meat, especially fats, without taking sufficient exercise. A few sulphur baths at specially prepared places behind the lines soon eradicate this trouble. Really dangerous diseases are extremely rare. Typhoid fever is almost unknown, pneumonia is seldom heard of and even rheumatism, which one would naturally expect to be prevalent, is by no means common. The ratio of sickness, from all causes, was far below that in any of the training camps in this country although never, in Canada, England, Flanders or France, did we have as comfortable quarters as are furnished for all the troops here. But we _did_ have at all times, plenty of good warm woolen clothing and an abundance of substantial food. Cotton uniforms, underwear or socks are unknown in any army except that of the United States. Perhaps you can find the answer in that statement.
