If you count up the men who have been wounded and invalided from all causes you will find that there are still twice as many sick people as there are wounded; and the strange thing is that as there are more wounds there is less sickness, because directly a “push” comes the men don’t think nearly as much about sickness as when there is nothing doing. If you take 1000 persons in ordinary civil life you will find that there will always be 3·3 sick per 1000; but at the front the rate is not quite half as many--only 1·8 per 1000 men. It is a very strange thing, but I have met with a number of men who were always more or less sick in civil life, yet who got quite well again at the front. The trenches are the place for a change of air! I am sure that after this war a very great many men will never go back to the civil life they were in before. They must have more life in the open air; and there can be no finer field for them than that glorious Canada which I know so well, with its boundless possibilities of harvests and material development. One is impressed at the front with the apparent valuelessness of human life, and deeply impressed by the lavishness with which that life has been laid down by all ranks for King and country. This remark applies to every rank of life without exception, to the highest of the aristocracy as well as to the humblest private. And very remarkable, too, is the zeal and willingness to serve in quite subordinate positions of men who have had every advantage in life, particularly the University type. I remember at one place, when we were sitting in the mess, a sergeant brought in a paper, which he handed to the colonel to read. It was a most elaborate scientific treatise on the body vermin that so greatly trouble our troops, and it was beautifully illustrated. In addition to that the paper showed the willing endurance of personal suffering for practical purposes that I for one should not have cared to undergo, for the sergeant had made himself thoroughly well acquainted with the effects of the visitation of the pests he described. I was so much impressed by the performance that I said to the colonel, “Who is your sergeant?” and he replied, “Oh, he’s the Professor of Entomology in the University of ----!”
