covered, and, so far as known, the only method of multiplica- 

 tion is from the vegetative mass itself. 



Pachyma cocas has been found as far north as New York 

 and Pennsylvania and is reported from Virginia, North and 

 South Carolina, Tennessee, Georgia, Mississippi, Kansas, Ar- 

 kansas, Texas, and Florida. Apparently, while there is no 

 definite limit to its occurrence in the south, it does not occur 

 where the ground is subjected to prolonged freezing. Ordi- 

 narily the character of the soil has something to do with its 

 growth, since it is almost invariably found in a light loam or 

 sandy soil where there is not excessive moisture. Similar un- 

 derground growths comparable to the American tuckahoe have 

 been found in other parts of the world. Indeed, it is probable 

 that the Fuh-Ling of the Chinese materia medica is the same 

 as Pachyma cocos. There are likewise other underground 

 fungous growths which seem to differ considerably from the 

 true Pachyma but in tbe absence of reproductive bodies it is 

 impossible to state whether there is any real affinity or not,
