According to the experiments of M. Hinu-eber, of Moisburg, Germany, one hundred Hanover quarts of milk yielded, in tinned milk-pans, 707 Hanover lbs. of butter ; Glass, 7'04 Wooden (not painted), 6'96 ; Earthenware, 692 ; Wooden (painted), 667. According to the same experiments, there required for one ot millc ; produced bystail-feeding with tare and clover, 15-67 quarts; by pasturing, 11-84 showing that the milk obtained from cattle fed upon pastures is richer in butter than milk got from cows which have been fed in the stable with one and the same kind of plants: even a mixture of tare and clover shows an increase over clover alone.— I Poly tec.

In some dairies, however, all the milk is churned, and we should suppose that this was the best way to obtain all the butter in the milk. There is no butter in the tin, therefore, we suspect, that one vessel is just as good as another, if clean, in which to churn the milk.
