tors are being made constantly, it is impossible for any one person to collect 

 sufficient data to determine this point. However, there are a few points 

 concerning separators that should help to guide the buyer of one. The 

 following is a list of these points: 



I. Size. — Ordinarily for farm use, a separator should be of such a size 

 or such a capacity that it will separate the milk produced by a herd at one 

 milking in one-half hour or less time. Usually a farmer's time is worth 

 enough to make it cheaper for him to buy a separator that is large enough 

 to do his separating in the proper length of time than it is for him to use 

 more of his time in operating a smaller machine. 



There are conditions on the farm that must be considered in the selection 

 of a separator of proper size. It may be the plan of the farmer to increase or

 The gasoline engine is located in the lean-to 



decrease the size of his dairy herd, and, since a separator will wear for many 

 years, these plans for the future must be borne in mind. In buying a 

 separator for creamery use, both the maximum and minimum amounts of 

 milk for different seasons of the year should be considered. 



2. Supplies for repairing pttrposes. — The obtaining of supplies without 

 difficulty is one of the most important considerations in bu}'ing a separator, 

 and this point should be especially emphasized in localities where trans- 

 portation facilities are rather limited. Most of the companies manufac- 

 turing cream separators have supply centers in many sections of the 

 country, so that in case of a breakdown new parts can be quickly obtained. 

 Some dealers in separators carry a stock of supplies. 



3. Other factors. — The other factors to be considered need but little dis- 

 cussion. The following ones are mentioned so that the prospective buyer 

 of a separator may have a fairly complete list of the points to be considered.
