HOW TO USE HAND SEPARATORS. 
Professor H. H. Dean, of Canada, gives the following good advice :—A. 
great many who use hand separators take the warm cream from the separator 
and put it in with the cream that has been skimmed in the morning or the 
previous day. That practice will result in a poor quality of butter every time. 
Cream from the separator should always be cooled at once to a temperature of 
60 degrees, or lower, otherwise it will be worse for butter-making than that 
obtained in the old way without separators. Neglecting to wash the machine 
properly and neglecting to cool the cream properly are the two great evils to 
guard against in the use of a hand separator. If these two points are very 
carefully observed, we shall have a better quality of cream, but not otherwise. 
MAIZE ACREAGES FOR VARIOUS SILOS. 
After a paper recently read at the Kansas State Dairyman’s Association 
the author answered the following amongst several other questions :— 
What is the estimated size of the silo needed, and number of acres 
required for a given number of cows, for a feeding season of 180 days ? 
I have arranged the figures in the following table :—
