which are also heavy; by dry beans, which take too long to cook to suit 

 me, or by dried egg. I depend largely upon this last. It comes in 

 convenient-sized cans and has proved very satisfactory. One can make 

 omelette or scrambled eggs, or it can be mixed with the flour for cakes. 

 I use the last method frequently, putting into the flour the equivalent 

 of two eggs. Fruit is an essential in camping. I prefer dried cherries, 

 but if these can not be obtained, I use prunes, dried peaches, apples or 

 whatever is available. A package of raisins is a good thing to have. 

 Of the condiments I carry only salt, as I do not care for pepper, vinegar 

 and so on, which are inconvenient and superfluous articles for a pack. 

 There are various kinds of concentrated soup packages on the market 

 only one of which I have found worth carrying. That is erbswurst, sold 

 by Abercrombie & Fitch Co., of New York. It is put up in pound, half- 

 pound and quarter-pound packages and consists of a meal ground from 

 peas, vegetables and meat, seasoned, ready for use by adding water. It 

 is a balanced ration easy to prepare and very concentrated. On a forced 

 march one could subsist upon this alone. 



The miscellaneous portion of the outfit includes a few toilet articles, 

 a pocket dissecting outfit, together with bandages, carbolated vaseline, 

 etc., for patching myself in case of accident, needle, thread, twine, 

 safety-pins and similar small articles. For packing these and the food 

 not contained in the original cases I use small cloth bags. The sugar, 

 dried fruit, rice or even the flour or cream of wheat, is transferred to a 

 cloth sack, as paper sack or pasteboard boxes will not withstand close 

 packing. 



The greater part of the outfit is carried in a pack upon the back. 

 If the bulk is small an ordinary soldier's knapsack is satisfactory. 

 When it is necessary to carry more the outfit may be placed in two 

 waterproof duffle bags and these carried in a strap pack. The most 

 satisfactory pack that I have tried is the Merriam pack by which a por- 

 tion of the weight is supported at the hips. 



In a trip of three to five days from a station, the outfit consists, 

 then, of the Merriam pack in which is placed every thing except the 

 poncho and blanket which are folded in a roll on the outside, the plant, 

 digger carried at the belt and the plant press carried in the hand. I 

 carry in addition a haversack for overflow articles. I try to start with 

 two loaves of bread, which being too bulky for the pack I place in the 

 haversack. In this I carry also my note book and drinking cup. 



Having decided upon a route for a short trip, which should be ar- 

 ranged if possible so that no portion is traveled over twice, I carry my 

 pack to a favorable locality for collecting and unload. After exhaust- 

 ing the collecting I move on to another place. Occasional plants are 

 dug up without removing the pack but this is somewhat of a strain and 

 should not be done regularly. One is obliged to rest every two or three
