INEXPENSIVE HOME-MADE TREATER 
Opposite are the plans for constructing an effective rotary treater for disin- 
fecting small lots of cotton seed, as well as grain, corn, sorghum and other seeds. 
This double-acting treating machine will thoroughly apply the disinfecting powder 
to every seed. It rolls and throws the seed against a mixing board and in addi- 
tion, surges them from one end of the drum to the other. These two motions cause 
the dry disinfectant to be evenly and completely spread over every seed, thus 
insuring the most efficient disease prevention and control. It also is dust-tight, 
an added advantage. 
This treater can be made from a 50-gallon drum, and costs only $2 to $5. Write 
for treater specifications and seed treating chart.
