the collecting season, protected by a specially organized 

 police force numbering several thousand men. The col- 

 lectors must sell the crude camphor to the Japanese govern- 

 ment, which refines it for the market. The government 

 sells the refined camphor through a single agent, who is 

 required to regulate the price in all parts of the world, to 

 prevent speculative enterprises in it. Crude camphor is a 

 loose, spongy, crystalline mass, saturated with camphor 

 oil. This oil is also an important commercial article. 

 Woods. Cases 119 and 200. — The east wing is occupied 

 by woods. The exhibits fall under two main divisoins, 

 the one consisting of a series of wood-specimens from all 

 parts of the world, and crude wood-products such as pipes, 

 canes, shoes, sandals, utensils, and carbons or charcoals; 

 the other being a synoptic collection illustrating North 

 American dendrology. The wood specimens consist either 

 of blocks of wood, or of sections of trunks with the upper 

 part cut so as to show the long grain of the wood and also 

 the cross grain. In the case of wood-products the crude 

 material and the finished product is shown when possible. 

 The collection of North American dendrology is based on 

 specimens of the wood of all North American trees. To 

 these wood-specimens are added specimens of the twigs, 

 of flowers, of fruits, and of other objects of interest from 

 the various trees. 



2. THE MUSEUM OF SYSTEMATIC BOTANY 



This occupies the entire second floor of the building and 

 is designed to illustrate by specimens, drawings, and 

 photographs, types of all the natural families of plants, 

 beginning with those of the simplest structure and ending 

 with the most complex. It consists of four series of 

 objects: 



(a) The general synoptic collection. 



(b) A series of microscopes showing selected specimens. 



(c) Illustrations of the local flora. 



(d) Plant photograph exhibit.
