churn, butter worker, cream vat, boiler and engine and a number 

 of smaller utensils. The average cost of equipment of dairies 

 visited was .^175. The most common equipment will not come to 

 this average, consisting as it does of a separator of 400-600 

 pounds capacity, a barrel or swing churn of from 20 to 60 

 pounds capacity, a worker of about the same relative size, a 

 Babcock tester and a few smaller utensils. The cost of such an 

 equipment is between i|^90 and $150 dependin<i' on the sizes of the 

 apparatus. In a dairy lately equipped witli a separator, 900 

 pounds capacity, and a combined churn and butter worker of 60 

 pounds capacitj^, an engine, necessary shafting, belt and all 

 smaller articles such as butter mould, butter papers, etc., the to- 

 tal cost was $307. 



To have good equipment is important to make a success of 

 butter-making. It makes it possible to do more rapid and effi- 

 cient work, to do it easier and to make a better quality of butter. 

 Furthermore, it adds to the attractiveness of and increases the 

 interest in the work. During the last year several large farm 

 dairies in the state have been equipped with combined churns. 

 The advantage of this churn over a separate churn and a sep- 

 arate worker is that it saves the labor of removing the butter 

 from the churn and handling it during working. The butter is 

 worked in this churn without being exposed to the air, thus pro- 

 tecting it from dust and possibly flies and from being subjected 

 to rapid changes in temperature. In creamery butter-making, the 

 combined churn has for several years estal)lished its superiority 

 over the box churn, but apparently has, until recently, been con- 

 sidered impractical for farm dairies. Although it cannot be 

 recommended in all cases where butter is made, it undoubtedly 

 will prove convenient and profitable in dairies making 75 pounds 

 or more of butter per week.

The kind of power to provide for the farm dairy is a question 

 upon which it is often difficult to decide. Of the farms visited 

 where power was used five were using tread power, four gasoline 

 engines, one a steam engine and one a water motor. Although 

 electric power was not found in any of the dairies, wherever 

 available it should be considered, as it makes a very desirable and
