H. & H. Electrie Soil Sterilizers 
Now available in small sizes for the home or small commercial operator. These 
sterilizers operate practically without odor, at about 40 per cent. less power 
than other sterilizers. 
The value of sterilized soil is well recognized by commercial growers. Freedom 
from diseases often found in soils, freedom from weeds—these things are of 
real importance to all growers. 
Till now the small grower has been forced to such measures as baking the 
soil in the kitchen oven. The large grower has had to use clumsy systems of 
steam sterilization. 
Now, the H&H electric soil sterilizer—with aluminum heating elements— 
makes it really easy to have sterilized soil with a minimum of fuss. 
We do not furnish the soil container, which can be readily constructed locally 
from the plans we supply. ?-inch sound lumber is recommended. 
We supply the heating elements, and hardware for fastening them into your 
container. We can also supply a manually reset Thermostat to provide auto- 
matic operation.
