and reasonably profitable to the operator from a money con- 

 sideration. It is also of a nature particularly well calculated 

 to preserve or build up the fertility of the farm. There is no 

 product sold from the farm in our New England husbandry 

 that removes with it so little of fertilizing matter as this one 

 product of butter. 



A comparison of the plant food removed from the farm by 

 the sale of a ton of each of the following products illustrates 

 the point : — 



It is thus seen that butter removes practically none of that 

 most costly of all ingredients, nitrogen, and but a small 

 amount of phosphoric acid and potash combined. When the 

 value of a ton of each of these several products given is con- 

 sidered, the distinction in favor of butter is still more 

 apparent. As a conservator of fertility, then, there is no 

 business that will match butter-makins:. 



Factory Butter, 

 There are two systems of work in butter dairying. The 

 associated, where the work of making the butter and pre- 

 paring it fur market is carried on at a factory or creamery, is 

 the one now, properly, receiving most attention. By the 

 way of parenthesis, I wish to say I never could see the pro- 

 priety of giving a flictory where butter is made, the name 

 creamery. It is clearly a factory, as much as any establish- 

 ment where products are worked up into other and more 

 valuable forms. The word creamery, if it has an application, 

 should designate an establishment devoted to the creaming 

 of milk.
