parts of the machine, so that he will know how to put it together 

 correctly. He should understand its theory, or the principle 

 upon which it works ; know something* about the different causes 

 influencing its efficiency and durability. Great are the responsi- 

 bilities that rest at all times upon the man operating a separator 

 for, it is an expensive piece of machinery. 



If electricity is used as power, in the creamery, all that is 

 required of the operator is to know how to turn the switch and 

 oil the motor. But where gasoline engines or steam engines are 

 used, the requirements are greater. He must know how to 

 operate them and how to take care of them. He must see that 

 they are properly oiled and kept clean, and where the last men- 

 tioned is used, that a constant supply of steam is applied. To 

 do this, he must know how to take care of a boiler and be an 

 expert fireman. Here is where great responsibility rests upon 

 the creameryman for the boiler is not only expensive and easily 

 ruined, but it is dangerous. He should at all times know where 

 he is at ; see that safety valve and water gauge are in order ; keep 

 a constant, supply of feed water and have it as clean as possible, 

 and keep the flues cleaned and free the inside from scales as often 

 as needed. It is to be expected that he understands the theorti- 

 cal principle of a boiler and steam engine and the various influ- 

 ences affecting its efficiency. Order and cleanliness should also 

 be observed in the engine room; the floor should be kept clean; 

 oil and grease should not be allowed to accumulate on the floor 

 and be tracked all over and the tools should be kept in place. 

 Outward appearance of the creamery should not be neglected. 

 Trash of any kind should not be lying around and worn out 

 utensils should be piled orderly if necessary to have around; 

 water pools should be kept off the driveway and the holes filled 

 with cinders. The small things must not be overlooked, for 

 upon the creamery's general appearance depends largely its repu- 

 tation. 



And last, but not least, has the creameryman duties toward 

 the patron. They are numerous and I will not attempt to relate
