But it is very interesting to note the increase of attention given to camouflage. It occurred to some one--the wonder is that it did not occur to him sooner--that a mud-coloured tiger, a tiger with a khaki skin, would be more visible, not less visible, than a tiger with its natural bright stripes. It was our seamen who first grasped the importance of this truth and began to paint ships blue, yellow, and red, with a view to making it difficult for submarine commanders to see them. There are, I believe, a number of artists now engaged in drawing out colour schemes for steamers. I have seen a mother ship of hydroplanes which looked like a cubist picture. Landsmen are more conservative and slower to grasp new ideas. But even in my time in France tents were sometimes covered with broad curves of bright colours. They looked very funny near at hand; but they are--this seems to be established--much less easily seen by airmen than white or brown tents. It seems a short step to take from colouring tents to colouring uniforms. In the next war, if there be a next war, regiments will perhaps move against the enemy gay as kingfishers and quite as difficult to see. Fighting men will look to each other like ladies in the beauty chorus of a revue. By the enemy they will not be seen at all. War will not, in its essentials, be any pleasanter, however we dress ourselves. Nothing can ever make a joy of it. But at least those who take part in it will escape the curse of khaki which lies heavily on us. We suffered a good deal from want of music when I went out to France, though things were better then than they had been earlier. They certainly improved still further later on. Music in old days was looked upon as an important thing in war. The primitive savage beat drums of a rude kind before setting out to spear the warriors of the neighbouring tribes. Joshua's soldiers stormed Jericho with the sound of trumpets in their ears. Cromwell's men sang psalms as they went forward. Montrose's highlanders charged to the skirl of their bagpipes. Even a pacifist would, I imagine, charge if a good piper played in front of him.
