Human Foods. Cases 85-114. — The utter dependence 

 of man for sustenance upon vegetable products lends ex- 

 ceptional interest to the consideration of plants as foods. 

 While it is true that man subsists largely upon animal 

 food, these animals are themselves dependent upon vege- 

 tation, so that human dependence thereon is but one step 

 removed. . It is our intention, so far as possible, to have 

 represented in our food collection every natural vegetable 

 substance known to be used as food by human beings, and 

 also many of the more important manufactured food pro- 

 ducts made from such substances. In the case of culti- 

 vated products, it is not practicable to represent all of the 

 cultivated varieties, but in all cases, a sufficient number of 

 them are exhibited to illustrate the nature and range of 

 variation. The number of articles in this group is so 

 great that it has been found necessary to adopt some 

 special method of classification and arrangement. They 

 have therefore been grouped in the following divisions: 



A. Underground Portions. 



B. Aerial Stems, Buds, Leaves or Leaf-stems and Flowers. 



C. Fleshy Fruits and Seeds. 



D. Nuts and Seeds eaten in the dry state, such as Marrow 



Beans and Peanuts. 



E. The Cereal Grains and a few products of similar nature. 

 The articles in each of these classes are arranged in their 

 natural botanical sequence, from the lowest to the highest 

 plant. 



Group A — cases 85 and 86 — includes roots, rootstocks, 

 tubers and tubercles, and bulbs. Although some fruits, 

 such as the peanut, are produced subterraneously, it has 

 been thought better to place them under fruits rather than 

 in this group. In these cases will be found, not only such 

 staple root-crops as potatoes, sweet potatoes, yams, taro, 

 turnips, radishes, beets, and carrots, but also a large num- 

 ber of aboriginal foods, from many countries. Many of
