over the other languages of the world seems now to be assured. ON MARKING BOOKS It is an excellent habit, either in studying or reading, to mark one's books so that the important things stand out prominently. In this way, they are impressed on the mind and more easily remembered, and can, moreover, be readily reviewed for recitation, examination, or for use at some subsequent time. The habit of classifying knowledge according to its importance is splendid training and conduces to a clearer and more orderly mental arrangement of any subject. These remarks do not apply to borrowed books! THE CHOICE OF WORDS The right word in the right place is like a well selected ring on the proper finger; it is fitting, it is pleasing, and it conveys the correct meaning in a direct way. A man of rather ordinary ability, who was in prison, began a letter to his friend, as follows: "Me and my wife had a divergence." A colored mammy of somewhat mature years and wide experience with "husbands" asked a school girl to write a letter for her to her beau. "How shall I begin it, Aunt Dinah?" inquired the youthful scribe. "How erbout howsumebbah? I tink dat is a good word," Aunt Dinah replied. CHAPTER XV HOW TO LIVE WISELY A BRIEF outline is here given of what the Naturalist learned about this important subject and tried to teach his pupils. When we study the wonderfully complex and varied parts of the human body, some of them almost inconceivably delicate, we marvel that they can all work together harmoniously for a single day without something going wrong. "Strange that a harp of a thousand strings THE VALUE OF HEALTH It is difficult to realize how fundamental and farreaching is the blessing of health until one has lost it. Health should be cherished above wealth, learning, fame-everything except character; because it is necessary to the enjoyment and proper use of most other blessings and is the first round in the ladder of success in almost any field. The successful man keeps on hand a surplus of vital energy which carries him through all difficul ties; while the man whose system is poisoned succumbs to the least obstacle. To live a healthy life is in the reach of everyone, even if it is hard to be civilized and healthy at the same time. By attending properly to one's food, drink, air, work, play, rest, and mental equilibrium, it is possible to live long and happily and accomplish much more than the average man or woman. "The requisites of health are plain enough. Regular habits, daily exercise, cleanliness, and moderation in all things in eating as well as in drinking-would keep most people well." FOOD Lubbock Food should be simple, natural, clean, well selected, used in moderation, chewed well, and eaten under pleasant conditions. White bread and white sugar are unnatural; a dinner of meat and little else is unbalanced; when one feels lazy, let him skip a meal; if one has no friends at his table, let him read an interesting book. Enough should be eaten to maintain the proper weight. Mental work requires less food than physical. It is unwise to eat much just before or just after hard work. The The selection of food is very important. teeth and jaws require hard food; the stomach and intestines bulky food; the digestive juices certain raw foods, such as lettuce, fruits, nuts, and milk; the nerves whole wheat, oats, cream, and eggs; and the large intestine buttermilk, to control the harmful bacteria and enable one to live to a ripe old age. The ordinary sedentary person needs about 2,500 calories a day, of which only 250 should be protein, but the average person eats enough meat, eggs, cheese, beans, etc., to furnish two or three times that amount. This is not only expensive, but decidedly harmful, since it throws too much work on the liver and kidneys and is apt to fill the system with putrefactive poisons. A wholesome and well-balanced dinner would consist of soup, meat or fish, bread, potatoes, spinach, lettuce with oil and lemon juice, and custard. If candy is eaten at all, it should be only after the evening meal. Meat once a day is quite sufficient, and some experts believe that to be too much. In arranging a varied menu, the following list, each article of which contains 100 calories of food value, may be helpful by way of suggestion: An ordinary thick slice of bread, a large potato, an ordinary side-dish of sweet corn, a very large dish of oatmeal, a small slice of sponge-cake, one |
