since this is the portion which possesses the greatest value as a source 
of commercial products. 
DISTRIBUTION AND QUANTITY OF TOMATOES PULPED ANNUALLY. 
The tomato pulping stations are scattered over a large area, in-

series, the investigation has been restricted entirely to this area. 
In this connection it may be of interest to point out the size of

raw material it is necessary that the stations be located in tomato- 
growing localities, in order that only a minimum period of time may
