OPEN-AIR CULTURE. 



51 



mental evidence is at hand. It may be said, moreover, that some of 

 the regions which seem to be too warm for open-air culture may be 

 especially favorable during several months at a time for mushroom 

 growing in ordinary cellars, or in very simply constructed mushroom 

 houses. In those sections the winter and early spring months would 

 doubtless give the most satisfactory conditions; and this period, 

 fortunately, corresponds with the tourist season — a season w^hen the 

 market demands are greatest. It is also possible that wdth mulching 

 and with simple protection, mushroom growing may be successful in 

 some of the Eastern States.

Occasionally one reads of successful natural cultures of mush- 

 rooms: that is, the production of this plant in pastures, lawns, etc.. 

 under more or less natural conditions. At Columbia, Mo., the writer 

 has made numerous attempts to spaAvn plats in pastures and lawns; 

 but thus far failure has attended every attempt. The spawning has, 

 moreover, been tried at every season of the year. It is believed that 

 in the section of the country mentioned only exceptionally favorable 

 seasons will permit any success in this phase of open-air culture.
