"_Nuts_--A handful each of shelled nuts and raisins, with a cake of sweet chocolate, will carry a man far on the trail or when he has lost it. The kernels of butternuts and hickory nuts have the highest fuel value of our native species; peanuts and almonds are very rich in protein; Brazil nuts, filberts and pecans, in fat. Peanut butter is a concentrated food that goes well in sandwiches. One can easily make nut butter of any kind (except almonds or Brazil nuts) for himself by using the nut grinder that comes with a kitchen food chopper, and can add ground dates, ground popcorn, or whatever he likes; but such preparations will soon grow rancid if not sealed airtight. Nut butter is more digestible than kernels unless the latter are thoroughly chewed. "_Fruits_--All fruits are very deficient in protein and (except olives) in fat, but dried fruit is rich in carbohydrates. Fruit acid (that of prunes, dried apricots, and dehydrated cranberries, when fresh fruit cannot be carried) is a good corrective of a too fatty and starchy or sugary diet, and a preventive of scurvy. Most fruits are laxative, and for that reason, if none other, a good proportion of dried fruit should be included in the ration, no matter how light one travels; otherwise one is likely to suffer from constipation when he changes from 'town grub' to 'trail grub.' "Among canned fruits those that go farthest are pineapples and blackberries. Excellent jelly can be made in camp from dried apples. "There is much nourishment in dates, figs (those dried round are better than layer figs) and raisins. Pitted dates and seedless raisins are best for light outfits. And do not despise the humble prune; buy the best grade in the market (unknown to landladies) and soak over night before stewing; it will be a revelation. Take a variety of dried fruits, and mix them in different combinations, sweet and tart, so as not to have the same sauce twice in succession; then you will learn that dried fruits are by no means a poor substitute for fresh or canned ones. "In hot weather I carry a few lemons whenever practicable. Limes are more compact and better medicinally, but they do not keep well. Lime juice in bottles is excellent, if you carry it. "Citric acid crystals may be used in lieu of lemons when going light, but the flavor is not so good as that of lemonade powder that one can put up for himself. The process is described by A. W. Barnard: 'Squeeze out the lemons and sift into the clear juice four to six spoonfuls of sugar to a lemon; let stand a few days if the weather is dry, or a week if wet, till it is dried up, then pulverize and put up into capsules.' Gelatin capsules of any size, from one oz. down, can be procured at a drug store. They are convenient to carry small quantities of spices, flavoring, medicines, etc., on a hike. "Vinegar and pickles are suitable only for fixed camps or easy cruises.
