NOTE: The equivalent gallons concentrated from 10% to 70% solids are calculated from a table and not from analysis of the tank water and stick; therefore, are only approximately correct.
The steam cost at $0.132 per 1,000 pounds is far below present average conditions.
Quantity Stick Produced.
—The quantity of stick it is possible to produce is indicated in the following table:

The relative quantity of Stick to dried fertilizer produced is about 40%, but the stick is more valuable due to its higher ammonia content and the mixture of the stick with the standard fertilizer increases the value per ton of the fertilizer.

Fertilizer.
—In this department we discuss the manipulation of the products after leaving the tanking process in the case of tankage, and of blood, beginning with its release from the animal.
