Sure Crop MUSHROOMS 
Growing Mushrooms is Not Difficult 
Get Reliable Spawn. Start Right and the Results Are Certain and Profitable. 
We furnish every buyer of Mushroom Spawn with explicit directions for growing. If 
they are followed, nothing is so certain as big success. 
The Mushroom is a delicious, edible fungus. It produces no seed, but instead a white 
fibrous substance in broken threads called spawn, which is developed and preserved in 
horse manure and pressed in form of bricks. 
No expensive equipment is or ever will be necessary for the propagation. The plain 
fact is that anyone who starts right can grow Mushrooms successfully. An abandoned 
outhouse, or waste space in one, a shed, a basement or a cellar can be used for growing 
Mushrooms and will answer the purpose excellently.
