. The cultivated mushroom ... Mushroom culture. [from old catalog]. CONSTRUCTION OF MUSHROOM HOUSES 47 before casing, when the}' arc found to contain an excess of mois- ture. Freshly slacked and mixed in water it is used extensively to whitewash and disinfect the mushroom house, shelves, etc. Sulphur is probably the most effective fumigant used in the mush- room house. It is burned at the rate of 2 pounds per thousand cubic feet of space in a moist or steamed atmosphere. In a dry atmosphere the fumigant is not nearly so effective. The sulphur- ous gases penetrate all cracks and corners and destroy the spores, bacteria, and larvas of parasites. It should be applied when the mushroom house is empty of beds and has been cleaned and swept out. It should never be used where beds are in bearing. CONSTRUCTION OF MUSHROOM HOUSES In a general wa}' it may be stated that the mushroom house should be so constructed or equipped that a unifonn temperatiu"e may be maintained therein and a gradual renewal of the air in- sured. The i^roblcms involved are, therefore, temperature and ventilation, and the method of their solution in the construction of the mushroom house will varv according to MUSHROOM HOUSE, PARTLY. UNDERGROUND The walls of the mushroom house, like the walls of the ice house, should be built of a material which is a poor conductor of heat, or should be so designed that the changes in the outside temper- ature will least affect the inside temperature. Double or hollow walls are preferable, as they are not so easily penetrated by heat or cold. The space between the inner and outer wall may be filled.
