"What signifies philosophy that does not apply to some use? May we not learn from hence, that black clothes are not so fit to wear in a hot sunny climate or season as white ones; because in such clothes the body is more heated by the sun when we walk abroad, and are at the same time heated by the exercise, which double heat is apt to bring on putrid dangerous fevers? That soldiers and seamen, who must march and labour in the sun, should in the East or West Indies have an uniform of white? That summer hats, for men or women, should be white, as repelling that heat which gives headaches to many, and to some the fatal stroke that the French call the _coup de soleil_? That the ladies' summer hats, however, should be lined with black, as not reverberating on their faces those rays which are reflected upwards from the earth or water? That the putting a white cap of paper or linen _within_ the crown of a black hat, as some do, will not keep out the heat, though it would if placed _without_? That fruit-walls being blacked, may receive so much heat from the sun in the day-time, as to continue warm in some degree through the night, and thereby preserve the fruit from frosts, or forward its growth?--with sundry other particulars of less or greater importance, that will occur from time to time to attentive minds?" But it might be objected to in Ceylon, as producing the very evils I would endeavour to correct, that of rendering the soldier too conspicuous. I would recommend, then, a light brown hat, with a brim sufficiently broad to protect the lower part of the head and neck against the sun or rain, and also to conduct the water over the cape of the jacket, without being too large to interfere with the perfect use of the musket; the under part of the brim to be green, as a relief to the eyes. It might also be advisable to have the hat a slight degree larger than the head, to allow of a pad between it and the forehead, for the purpose of leaving an open space round the temples to admit of a free circulation of air. This kind of hat might appear to some unbecoming; but we must recollect, that the health and comfort of the soldier should be our first consideration. _Of the Carriage of Baggage and Stores._ There is nothing that embarrasses more the operations of our Ceylon forces than the carriage of baggage and stores.
