large one, requiring the services of more than one 
man, that the “gravity” system is preferable, _be- 
cause of doing away with the objectionable pumps. 
Whereas, if the factory is to be a small one, and 
one man is to do all the work, the amount of 
labor saved by the more compact pumping. system 
will more than overbalance the objection arising 
from pumps. In a factory of the size indicated, 
handling from three to five thousand pounds of 
milk per day, a floor space of about 18x24 feet 
will be required. In larger factories, it will be 
found of advantage, in controlling the temperature, 
to introduce partitions, so that the receiving and 
separating room may be separated from the churn- 
ing and working room, and if much butter is to 
be made up into prints, a third, colder room, for 
printing the butter, will be found of great advan- 
tage during the warm part of the year. Here, too, 
the question of labor again comes into play. When 
‘the creamery is so small that all the work is done 
by one man, labor is economized by having all the 
operations conducted in one room, but where two or 
three, or even more men are employed, it will be 
found of advantage to have separate rooms for the 
different operations. 
Construction.—The building should be laid upon 
solid foundation walls rather than upon piers. 
Besides adding. decidedly to the appearance of the 
building, it aids materially in keeping the build- 
ing warm in winter and cool in summer. In regard.
