UTILIZATION OF WASTE SEED FROM THE TOMATO. 7 



A 5-mesh woven screen made of No. 12 wire has been found very 

 satisfactory. 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 with this method for more than 

 two seasons at the Arlington Experimental Farm near Washington, 

 D. C, confirms the conclusions as to its effectiveness.
