The prices above given are for the standard varieties of the cul- 

 tivated mushrooms which are herein mentioned or illustrated. 



Bricks of "Lambert's Pure Culture Spawn" are of two kinds, 

 standard bricks and direct bricks. The "standard brick" is in- 

 oculated from a pure culture transfer. The "direct brick" is in- 

 oculated directly from the pure culture, as raised in the laboratory, 

 without intermediate transfer. 



By reason of the increased laboratory work involved, 'an addi- 

 tional charge of 3 cents per brick above the price of standard bricks 

 is made for the direct bricks. Growers should bear in mind this 

 distinction in ordering from dealers and specify the kind of bricks 

 wanted.
