Grow Mushrooms th at Grow 



Mushroom culture has all the attractiveness of the flower 

 garden combined with the satisfaction and financial returns 

 of truck gardening. The home grower and the commercial 

 producer alike secure large results from our spawn. 



Pure Culture Spawn makes it possible now, for the first 

 time in the history of this industry — 



For the novice to secure good results with ordinary care 

 and attention to his work — 



For growers every where to have mushrooms of definite selected species, uniform in 

 color, size and quality — 



Because every brick is inoculated direct from test-tube cultures. 



We are pioneers in applying the principle of selection to spawn growing, and origina 

 tors of pure and superior varieties of cultivated mushrooms. 



Note Our Improved Varieties

 very large, regular buttons, a good cropper. This 

 form requires less moisture in the bed than Agar- 

 icus Campestris.

This is a new species especially suited for high temper- 

 ature. 



ALMOND : A firm white mushroom, above medium 

 size. Thrives in a temperature between 56° and 

 80° F. Has unique flavor similar to that of the 

 almond, hence the name. Ranks with Eureka in 

 productiveness. Spawn ready July 15, 1907. 



Agaricus arvensis. 



EUREKA : This variety has a smooth brown cap, uni- 

 form in size, shape and color. A good producer 

 and excellent shipper. Record 32 to 40 ounces. 



This is a hardy form, good for summer and 

 winter planting. It produces fine plump mush- 

 rooms at 70 degrees. We recommend Eureka 

 as best for the amateur and for those who wish 

 to grow mushrooms in the_open. 



Pure Culture Spawn comes in bricks of especially prepared compost that gives the 

 greatest amount of active spawn per cubic inch of brick. These bricks weigh approxi- 

 mately 1 X A pounds and will seed 1 2 square feet of beds. They are clean and do not 

 contain a surplus of loam. 



We endeavor to fill all orders on the day received. Write to us for our new booklet 

 "Mushroom Spawn and Guide to Mushroom Culture." The fourth edition has just 

 been printed.

EXPERIMENT STATION TESTS 



Our Pure Culture Spawn has been tested by a 

 number of experiment stations and its superior mer- 

 its are substantially endorsed. 



The Cornell University Experiment Station reports 

 in its Bulletin No. 227 "Mushroom Growing for Ama- 

 teurs ": 



"It is possible with the method employed by this 

 Company to cultivate varieties true to the name 

 because the spawn is derived from known varieties, 

 whereas most or all of the imported spawn may 

 contain several varieties mixed."
