The juices of other plants are also used in making sugar, 
for example, in temperate regions, the sugar-beet yields 
an enormous amount, the sap of the maple tree is made 
into maple-sugar, while in tropical regions the sap of various 
palms, such as the coconut-palm and the sugar-palm, 
is made into palm-sugar. 
Foods. Cases 75 to 100.—The very important section 
of vegetable foods occupies the cases on the north side of 
the west hall, opposite those containing the fibers. Here 
may be seen the various plants and parts of plants common- 
ly used for food. In a few instances nearly the whole 
plant is available, as in the mushroom, the morel, and the 
truffle. Usually, however, certain parts only are nutri- 
tious or desirable; a few examples of these are as follows: 
sweet-potatoes, horseradish, carrots, and beets are roots; 
onions, potatoes, and Jerusalem-artichokes are under- 
ground stems or rootstocks; asparagus and poke-shoots 
are young stems; lettuce, beet-tops, spinach, and parsley 
are leaves; cauliflower and calamus-buds are inflorescences; 
corn, rice, bananas, mulberries, gooseberries, apples, to- 
matoes, and oranges are fruits; while peanuts, walnuts, 
hickorynuts, beans, almonds, and chestnuts are seeds. 
rugs. Cases I01 to 118 and 201 to 218.—The east 
hall is given over to drugs. This, like the department of 
foods, is large and important. The active principles or 
medicinal agents are stored up in the tissues of the plant 
or in the tissues of special organs. The great majority of 
refined drugs are derived from one or more of the parts of 
the plant, but in the case of the white-agaric, ergot, Irish- 
moss, Iceland-moss, wintergreen, sundew, bitter-sweet, 
penny-royal, boneset, and tansy the whole plant is used. 
A few of the crude drugs arranged under the several 
plant-organs they represent are as follows: sarsaparilla, 
poke-root, rhubarb, aconite, queen’s-root, senega-root, 
marshmallow, man-in-the-ground, and ipecac are roots; 
calamus, ginger, colic-root, Canadian snake-root, soap- 
wort, mandrake, American-ipecac, buckbean, and stone-
