The amount of ash or of nitrogen in butter is almost nothing, 
the quantity present being too small for consideration from our 
present standpoint. | 
From the tables presented we may judge pretty closely of the 
amount of fertility removed from our soil by the sale of milk, 
cream and butter. By feeding the skim milk upon the farm, 
and selling the cream, we only remove about one-tenth as much 
as would be found in the whole milk. If the skim milk and 
buttermilk are all consumed upon the farm, and only the butter 
sold, then the amount of fertility sold from the farm in the way of 
nitrogen, phosphoric acid, potash and lime is almost nothing.

The number of pounds of cream for one pound of butter will 
vary for individual animals and for herds under like conditions of 
creaming. Dif Potent methods of creaming the milk will give dif- 
ferent results. Bélow are given the average number of pounds of 
cream for each month required to produce one pound of butter in 
the Station herd. The Cooley system of creaming the milk was 
used, and the skim milk drawn down as close to the cream as 
possible.
