NATURAL HISTORY SURVEY 17 



preserving the shape, color and consistency of these plants has 

 yet been devised. Until some good process is invented we must 

 have recourse to photographs, drawings and descriptions. 



POISOXIXG. Fungi in the herbarium are very liable to the 

 attacks of insect pests. Before storing a collection of dried 

 plants it is well to fumigate the specimens in a tight box (a tin 

 wash-boiler is convenient for the purpose) in which a saucer of 

 carbon disulphide has been placed. The process should be re- 

 peated after a few weeks to destroy any eggs that escaped the 

 first fumigation. Naphthaline kept in the boxes with the plants 

 will keep out insects but will not stop the ravages of those that 

 may already be in the plants. 



STORING ix THE HERBARIUM. For methods of sectioning, 

 pressing and mounting fleshy fungi- upon herbarium sheets, 

 reference may be had to the manuals. To us all these methods 

 have seemed unsatisfactory, and our collectors keep all of their 

 plants just as they were dried, in convenient sized cardboard, 

 wood or tin boxes. Methods of labeling and arrangement of 

 species, genera, etc., in the herbarium do not differ from those 

 used in herbaria of the higher plants, and call for no special men- 

 tion here.
