From these machines the seed would be conveyed directly to the 
rotary or the tray driers and thence into the storage house. The 
whole operation would thus be continuous, and labor would be kept 
down to a minimum. 
It is understood, of course, that this portion of the plant would 
operate only during the pulping season. If the oil were to be ex- 
tracted at this central point, oil expellers could be installed and the 
seeds crushed during the winter months. 
To handle this material it would be necessary for some operating 
company to install a plant at some central point, as suggested above. 
Preferably all the seed-separating machines installed at the various 
pulping stations should belong to the operating company and be as- 
signed to the local concern, the cost being charged against the in- 
vestment. The matter of credits to the pulping plants for seed 
contributed could be established by buying on a tonnage basis figured 
as wet or dry seed, as the case warranted. 
As an alternative there could be a cooperative holding company 
consisting of all the seed producers, who would handle the seed to 
the drying stage and then either install an oil mill for pressing it 
or contract with a regularly established oil mill to make the crush. 
In any event the profits would be divided among the stockholders 
(cooperating firms). This would insure the necessary tonnage of 
seed supply and at the same time involve the use of but little ma- 
chinery outside of that regularly used in a pulping station. It is 
recognized that the individual profits would be small, but withal 
far more than are now realized, for in most cases the seed is now an 
actual expense. It is even suggested that there be a national asso- 
ciation of the canners to operate the plan, thus profitably utilizing 
another waste material, as is already being accomplished in many 
other lines of canning and packing. 
The second plan involves no central utilization plant as such. 
Under this plan seed-separating cyclones would be installed at every 
pulping station, together with a drier, preferably the tray drier 
previously described, on account of its more adaptable size. Since 
it costs but little more to operate a large than a small drier, it would 
probably be best to install one large enough to handle the entire 
output of a given station within two or three days. By this plan 
the seed would be allowed to accumulate for that length of time 
and would be dried at once, thus reducing the cost of labor to three 
days a week. The individual plant would be under no charge for 
cyclone or drier, as these would be installed by the operating com- 
pany and the initial cost of installation would be borne by the 
capitalization. If made in lots of 25 or 50 of standard pattern, the 
cost of the driers would be reduced to a minimum. The dried seed 
could then be shipped when convenient to some central regularly
