UTILIZATION OF WASTE SEED FROM THE TOMATO. 7 
A 5-mesh woven screen made of Xo. 12 wire has been found very 
satisf actory. There is a greater tendency for the small pieces of skin 
to go through the meshes with the seed than for the seed to remain 
back with the skins ; in other words, the operation is in favor of the 
seed. The stream of pulp and seed is pumped into an adjoining 
cyclone provided with an ordinary breaker screen (about 20-mesh), 
the perforations of which 
are too small to permit 
the passage of the seed. 
The pulp or juice then 
flows out in a continuous 
stream, while the seeds 
pass out through the gate. 
Inasmuch as the two ma- 
chines are placed together, 
preferably one behind the other, and one man operates both, it follows 
that this operation necessitates practically no increase in labor and is 
continuous and efficient. Experience Avith this method for more than 
two seasons at the Arlington Experimental Farm near Washington, 
D. C, confirms the conclusions as to its effectiveness.
