engine will do just as well. The advantage of a gasoline engine, you 

 can stop it or start it almost any time when ready for milk, and in case 

 of a steam boiler we have to wait. And then if you have a small boiler 

 you don't necessarily have to heal, your water up so high as if runing 

 with power. A gasoline engine has a little the advantage over the 

 steam engine for cream separation. 



Q. — I think I have heard complaint about gasoline engines giving 

 uniform speed? 



A. — No sir. That depends on the gasoline engine somewhat. What 

 we call the one cycle engine is very ununiform speed, but the modern 

 size, the two cycle engine gives a regular speed, and are used often for 

 lighting plants which requires a steady kind of speed. Quite a number 

 of gasoline engines operate electric light plants; that is the most sen- 

 sative apparatus that we can get, requiring the least variation. 



Q. — Why would it not be a good plan, in the use of a farm separa- 

 tor by hand, to have some sort of a time-keeper, a pendulum, or rather a 

 cyclometer; why wouldn't that be a good idea? 



A. — I should think some of you would have trouble in persuading the 

 man to keep an eye to the pendulum all the time. 



Q. — It would not be necessary to keep an eye all the time, an ear 

 w r ould do it? 



A. — Yes sir. There is a little scheme invented especially for large 

 machines, by which they had a little governor on the spindle, and this 

 governor would open by an increase of speed and would strike a little 

 bell if opened a certain distance; and then it would come back again the 

 opposite way and open up and strike another bell which would indicate 

 a slow speed. But the trouble is with this high speed, and on such a 

 small circumferance, to keep that governor in shape. It will indicate 

 speed sometimes twice before the bell rings, and for that reason it really 

 is not successful. There is a need of an apparatus to determine the 

 speed of a separator bowl on both kinds of separators, that is if the in- 

 Tention can be made simple enough and accurate enough.
