This is very easily understood. Wool is a non-conductor. In winter, therefore, it conserves or retains the internal or animal heat, and in summer it will defend the skin and the blood from becoming fevered by the scorching rays of the sun. I do not expect my youngest readers to be interested in one-half of what I am now writing, but I most earnestly desire their mothers and guardians to lay my words to heart, and to act upon them, so that they may not hereafter have to say, with sighs of regret— “I wish I had.” There is one other little matter I wish to point out to my thoughtful mamma-readers, with regard to clothing, and that is, the absurdity of not having dress, either for boys or girls, made the same thickness at the back as at the front. It really is ridiculous to clothe the chest in front and leave it to starve between the shoulders. I have before now pointed out to you that people catch colds in the chest far more often from chills caught from behind. _Verbum sap._ Well, now I shall change my tune, and go on to another subject which also has a bearing upon colds and coughs and ill-health of every kind engendered by wintry weather. One-half of the people in this country are not breakfast-eaters. Are you really a breakfast-eater? Do you get hungry as soon as you have had your bath? As soon as you have said your good-morning, do your eyes roam over the table-cloth with a wholesome desire to know what is on board? If you are healthy, and have discussed that matutinal meal, nothing can hurt you all day. You may walk through the most unwholesome streets and lanes in the City, and come forth intact. On the other hand, do you feel languid when you get up? Do you cast a longing, lingering glance behind you as you commence to dress? Do you come downstairs caring little what is to eat? Are your fingers numb and cold? Do you require to slowly sip a cup of tea before getting an appetite even for toast and butter, and that new-laid egg you have to coax yourself to eat? If so you are not in health. Go not anywhere during the day where you are likely to breathe a tainted air, or be influenced by cold or damp. If you do not take my advice in this respect you may live to say—“I wish I had.” But have I no remedy to suggest for my breakfastless readers? Oh, yes, I have! There is a cause for everything. Your want of appetite in the morning may depend on one or other of many things. To be sure, it may be constitutional. You may have a weak heart and be altogether delicate in consequence. But ten to one you have nothing of the sort. Besides, if your heart be only functionally weak, do not forget that it is a muscular organ, as much so as your forearm or biceps, and, like the biceps, can be strengthened by good food and plenty of pleasant exercise in the open air. But there are other reasons why appetite absents itself at the breakfast hour. As my space is nearly filled, I can but name a few.
