If pork be used, in order to avoid transporting about forty per cent. of useless weight, it should be taken out of the barrels and packed like the bacon; then so placed in the bottom of the wagons as to keep it cool. The pork, if well cured, will keep several months in this way, but bacon is preferable. Flour should be packed in stout double canvas sacks well sewed, a hundred pounds in each sack. Butter may be preserved by boiling it thoroughly, and skimming off the scum as it rises to the top until it is quite clear like oil. It is then placed in tin canisters and soldered up. This mode of preserving butter has been adopted in the hot climate of southern Texas, and it is found to keep sweet for a great length of time, and its flavor is but little impaired by the process. Sugar may be well secured in India-rubber or gutta-percha sacks, or so placed in the wagon as not to risk getting wet. Desiccated or dried vegetables are almost equal to the fresh, and are put up in such a compact and portable form as easily to be transported over the plains. They have been extensively used in the Crimean war, and by our own army in Utah, and have been very generally approved. They are prepared by cutting the fresh vegetables into thin slices and subjecting them to a very powerful press, which removes the juice and leaves a solid cake, which, after having been thoroughly dried in an oven, becomes almost as hard as a rock. A small piece of this, about half the size of a man's hand, when boiled, swells up so as to fill a vegetable dish, and is sufficient for four men. It is believed that the antiscorbutic properties of vegetables are not impaired by desiccation, and they will keep for years if not exposed to dampness. Canned vegetables are very good for campaigning, but are not so portable as when put up in the other form. The desiccated vegetables used in our army have been prepared by Chollet and Co., 46 Rue Richer, Paris. There is an agency for them in New York. I regard these compressed vegetables as the best preparation for prairie traveling that has yet been discovered. A single ration weighs, before being boiled, only an ounce, and a cubic yard contains 16,000 rations. In making up their outfit for the plains, men are very prone to overload their teams with a great variety of useless articles. It is a good rule to carry nothing more than is absolutely necessary for use upon the journey. One can not expect, with the limited allowance of transportation that emigrants usually have, to indulge in luxuries upon such expeditions, and articles for use in California can be purchased there at less cost than that of overland transport. The allowance of provisions for men in marching should be much greater than when they take no exercise. The army ration I have always found insufficient for soldiers who perform hard service, yet it is ample for them when in quarters.
