mu>st be a-ble to return tu one's base every night. Specimens col- 

 lected on one day's march cannot he preseri'ed and carried on as in 

 the case of flowering plants, with the exception of course of the 

 hard woody kinds, as the characters must he worked out whilst 

 they are fres^h and the fructifications rarely last over twenty four 

 hours. Fungi growing on leaves and of a similar nature can he 

 put into an ordinary press, but for all others it was found advisable 

 to collect them in baskets, wrapping each collection loosely in a 

 sheet of pa])er and ])lacing them on top of each other in the baskets. 



On arrival at caiup a certain number such as those of a leathery 

 ■or fibrous nature niav be sun dried, but the fleshy ones should be 

 soaked in spii-it for about five minutes. If they are fragile or it is 

 essential to preserve their shape, and they are of a nature to allow 

 this to l)e done, they may then be dried off in a press. Others such 

 as thick or caespitose specimens should lie dried otf gradually in a 

 hot air oven and preserved in boxes. 



Before being put away all specimens must be poisoned, but the 

 proportion of corrosive sublimate must not be sucli that it will fonn 

 a deposit on tlie specimen and block the pores. l)i the herbarium 

 <'a.binets balis of naphtliaiene should he placed on tlie shelves and in 

 the boxes, and a little ]X)wdered naphthalene between the sheets. 



Even with all these precautions it has been found necessary to 

 go over all the specimens every two or three months and poison 

 again where necessary. 



In dealing with the Agaricaceae the experiment Mas tried of 

 o'l)taining the spore cast on a glass slide, and so far this has proved 

 veiy satisfactory. It enaliles the spores to be examined by reflected 

 and transmitted light, and if the slides are kept in a slide cabinet 

 thev are liandy for future reference and comparison. It is neces- 

 sary, how('\('r. from time to time to examine them and when any 

 growth of mycelium is observed to wash tlie slide over with alcohol.

In the bibliography at the end the works quoted are those re-
