484 MUSHROOM CULTURE. 



As on an average 2500 yards of beds are made every 

 month, simple mechanical contrivances to facilitate the 

 operation will prove of the greatest advantage to the 

 cultivator. 



In addition to the caves in the localities above alluded to 

 there are -other places near Paris where the culture is carried 

 on — notably at Moulin de la Roche, Sous BicStre, near St. 

 Germain, and also at Bagneux. The equability of temperature 

 in the caves renders the culture of the Mushroom possible at 

 all seasons; but the best crops are gathered in winter, and con- 

 sequently that is the best time to see them. I, however, saw 

 abundant crops in thfthottest part of the past very hot season. 

 These Mushroom caves are under government supervision, and 

 are regularly inspected like any other mines in which work 

 is going on. As regards the depth at which this culture is 

 carried on, it varies from twenty to one hundred feet, some- 

 times reaching one hundred and fifty and one hundred and 

 sixty feet from the surface of the earth. They are so large 

 that sometimes people are lost in them. In one instance 

 the proprietor of a large cave went astray, and it was three 

 days before he was discovered, although soldiers and volun- 

 teers in abundance were sent down. Is it possible that in 

 a great mining and excavating country like ours we cannot 

 establish the same kind of industry ? 



Culture in Cellars and in the Open Air. 



Of course they are only professional Mushroom growers 

 that carry on such extensive operations as those just de- 

 scribed, but the Mushroom is 

 ~ :,i also grown extensively in cellars 



]K and like places. As an analo- 

 » gous mode of culture is more 

 ||& likely to meet general wants, the 



.TOl following observations on the 



Newly-made Mushroom Beds, subject may prove acceptable.

 sident of the Mutual Aid Society formed among the Paris 

 market gardeners.
