DINNER.--Lamb, mutton, beef, fowl (tender and boiled), varied by fish, of which haddock, whiting, and soles are the best, with potatoes (well boiled, and not much of them), and well-cooked vegetables, followed by a small allowance of light farinaceous pudding or stewed fruit, will be a good, wholesome diet. If you want bread, have it stale. Never eat _new_ bread. Avoid all sauces, or made dishes, and adhere to plain food only. One thing we would particularly impress upon the reader, and that is never to take his exercise immediately before or after meals, nothing is more injurious, or likely to produce indigestion, and its concomitant evils. Some authorities abjure the use of sugar, but taken in moderation it is not injurious. A well-known champion of our acquaintance, when in the pink of condition, was wont to amuse himself by eating the contents of a sugar basin, if one were inadvertently left near him, and without feeling any ill effects from so doing. Our readers need not follow his example, for although it might suit him, it probably would not agree with them. We have said, take sugar in _moderation_. Now, in this last word lies all the lectures one can give on this subject. Be moderate in all things, one might say, but above all things be moderate in the use of all edibles not actually necessary to support the increased exertion which a man in training is called upon to perform. No liquid should be taken except with, or just after meals, but we would not advise stinting the quantity too much. In summer three or four pints, and in winter two or three pints per diem would be about the quantity. Never drink just before exercise, and it is better not to drink just before going to bed. In fact, the less one has to digest when retiring for sleep the better, and be sure not to drink tea late at night. [Illustration: C. O. GILL. Yale.] TEA, or SUPPER, should be taken at least two hours before bedtime, and we would allow a small chop, or some light fish, bread, and very little butter, with some ripe fruit. The best meal to take before a race, and which should be taken about two hours before starting-time, is the lean of mutton-chops and a little dry toast. We have said that no liquids should be taken except at meal-times; but we do not intend to state that if a man be very thirsty he may not touch them. If he does so, it must be a very small quantity. Thirst can often be assuaged by rinsing the mouth out with cold water, and this is by far the better plan if it is efficacious. A COMMON-SENSE SYSTEM.
