fermentation method. This selection must be 
and is continued year after year in order that 
the high standard set for a variety may be 
maintained and improved. 
In order to check improved selections 
against the parent and competitive stocks 
many trials are conducted each year and the 
results carefully tabulated. These records to¬ 
gether with field performance are the guides 
for further selections. For proper tests of the 
wilt-resistant varieties many trials also are 
made on wilt-infested soil, giving us a com¬ 
plete check on the characteristics of the vari¬ 
ous varieties. 
For production, our seed is sown in beds 
soon enough in the spring so that without 
forcing, the plants will be ready to transplant 
directly into the fields in May. After plant¬ 
ing, rogueing is the next job requiring much 
care and here again special knowledge of 
variety characteristics is needed and thorough¬ 
ness in going through the fields must be exer¬ 
cised. This work begins as early as possible 
so that any off-type vines may be removed to 
avoid chance of cross-pollination and is con¬ 
tinued until after all plants have developed 
ripe fruit assuring a check on all points. 
Harvest soon comes on and as our tomatoes 
are grown only for seed we can give our full 
attention to our seed operations. The toma¬ 
toes are picked when full ripe, coarsely 
crushed to avoid seed injury and are run into 
barrels for a period of fermentation. At the 
end of this period, the pulp is poured into 
long flumes of moving water arranged with 
riffles at intervals behind which the good seed 
settles, allowing the pulp and light seed to 
float off. Thorough rinsing is accomplished 
by agitation of the seed in the flume, thereby 
releasing practically all waste material. Upon
