Spices and Flavoring Agents. Cases 23 to 26. — These 

 substances form quite a large series in which is shown the 

 parts of the plant that yield spices and flavoring extracts; for 

 example, licorice is extracted from the roots of the licorice 

 plant. Ginger is a rootstock, the underground stem of the 

 ginger plant; cinnamon is a bark; bay, sage, mint, thyme are 

 leaves; cloves are flowers; coriander, allspice, black pepper, 

 celery seed, caraway seed, vanilla bean and tonka bean are 

 fruits ; mustard and nutmeg are seeds, and mace is the outer 

 coat of the nutmeg. 



Dye Stufs. Case 27. — The dye stuffs are represented by 

 logwood, madder, alkanet root, indigo and oak galls. 



Tanning Materials. Cases 28 to 30. — The tanning ma-

 they are represented by saw-palmetto, mangrove, pine, hem- 

 lock and sumac. The crude materials of the mangrove and 

 the saw-palmetto are accompanied by the fluid extract which 

 contains the tannic acid and also by the spent material or 

 refuse which remains after the extract has been made. 



Fodder Plants. Cases 31 and 32. — Following the spices 

 are fodder plants, which are shown as sheaves, and consist 

 of grasses, sedges, bush-clovers and related plants. 



Tobaccos and Masticatories. Cases 33 to 36. — Tobaccos 

 are shown by a series of bundles of the cured leaves of the 

 tobacco plant (Nicotiana) from different parts of America, 

 and a series of articles as prepared for the market. Closely 

 associated with tobacco are the masticatories or substances 

 used for chewing. One of the most widely known forms is 

 chewing gum, which is made by refining the crude chicle- 

 gum, which is the hardened milky juice of the sapodilla and 

 related plants. In rural districts the exudation of resin 

 found on the bark of conifers is used for chewing while still 

 in the crude condition, but this substance is now refined and 

 sold in our larger cities just as is the now more commonly 

 used chicle-gum. An adjacent case is given over to:
