MUSHROOM (iROWINCJ AND SPAWN MAKING. 



The series of experiments outlined in Table IX followed directly 

 uj)on the series given in Table VIII. 'J'he beds in the first series 

 were made in midwinter, and as the manure had been well fermented 

 there was little or no rise of temperature after the beds were made. 

 The spawn was therefore inserted at an unusually low temperature. 

 Dnrino; thaws in the late winter there was considerable seepage 

 through the walls of the room. Some of the wall beds — Nos. 14 to 

 21 — were seriously damaged, but although beds Nos. 7 to 18 were 

 also wall beds seepage was not evident in this region. Within about 

 thirty days after vigorous mushroom production began in this series 

 the basement was flooded, and the work was therefore brought to an 

 abru])t close. The yield up to that time is given, however, since in 

 this series there are included many fertilizer tests.
