In addition to this, there will be an outlay for buildings, brick-

will be determined largely by local conditions and the factory site, 
but probably will approximate that for the equipment, bringing 
the total for plant and equipment to the figure mentioned above. 
In addition to this cost again would be added the items expended 
for tugs and scows. 
Superficially there seems to be no reason whatever why the auto- 
matic and continuous cooker in its present form should not be 
entirely applicable to salmon cuttings. The rate at which the ma- 
terial is passed through, and therefore the length of time during 
which it is being subjected to the cooking action of the steam, are 
regulated with ease. Thus the degree of cooking is under complete 
control. It has been demonstrated that cooking under pressure is
