ness in handling the product. When proper attention is given to these 
details a satisfactory product can be obtained, but it is in the exercise 
of the care required that many packers have failed. 
Why should the manufacturer desire to turn his trimming waste 
into pulp? Tests made at various factories have shown that 30 per 
cent or more of the weight of the tomatoes as received at the fac- 
tory goes into the waste known as trimmings. An examination of 
ordinary trimmings 
(rareq7065) shows them to consist 
of: (a) the skins from 
* peeled tomatoes; (0) 
vormuar, the stems and coarser 
part of the cores from 
around thestem end of 
the fruit; (¢) the de- 
cayed and rotten parts 
cut out from the other- 
wise good fruit; (d) 
tomatoes wholly de- 
cayed; and (e) small 
tomatoes, and others 
of such size or shape 
that 1t would be un-

If the trimmings were 
in good, clean condi- 
tion, it is probable that 
no serious objection

Figure 2 shows 
graphically a system 
for manufacturing 
pulp from _ tomato 
trimmings. Although when properly handled such a system should 
give a satisfactory product, it is complicated, and the extra labor 
required in the use of trimmings in the pulp may not in average 
seasons be compensated by the value of the product resulting. 
Because of the fact that a considerable part of the waste comes 
from small tomatoes which the peelers find it unprofitable to skin,
