1S6 ANNUAL REPORT OF THE Off. Doc. 



But the points of superiority in each, while almost equalling one 

 another, are entirely diU'erent from each other. The absolute neces- 

 sity, of a centrifugal cream separator in any whole milk factory, de- 

 voted to butter making, of course, will be conceded. So necessary 

 is the separator in such a factory, that without it the creamery would 

 be compelled to go out of business in very short order aod years ago, 

 all of them necessarily went out of business, or bought separators. 



Long after the whole-milk-gravity creamery had gone out of busi- 

 ness, the gathered-cream creamery, using gravity cans, held on and 

 thrived in many districts. It is still largely in use, but it is now 

 fast succumbing to the march of the farm separator. 



The fact that it held right on, in close competition with the sepa- 

 rator creamery, notwithstanding its heavy loss of butter fat through 

 imperfect creaming, amounting in itself to a big profit on the busi- 

 ness, shows that it must have had some advantage over the sepa- 

 rator creamery, sufficient to offset or equal the great gain in butter 

 yield, secured by the separator. In other words, the advantages 

 peculiar to the gravity-cream-gathering system, were the equivalent 

 of the advantages secured through the invention of the factory sepa 

 rator. Consequently, if we can devise a system that secures both of 

 these advantages, that is, those peculiar to the gravity-cream-gather- 

 ing system, and those due to the invention of the centrifugal sepa 

 rator, then we will have a system possessing twice the advantages 

 over the gravity- whole-milk system, that the factory-separator cream- 

 ery, which you are now conducting and patronizing, has over the 

 same system. 



Perhaps you don't fully catch my meaning. To explain more full}-, 

 if you are running a factory-separator creamery now, making say four 

 hundred pounds of butter a day, you are making, at least thirty-five 

 pounds more butter per day, than as though you were to set the same 

 milk in the old fashioned vats and raise the cream by gravity. At 

 twenty cents per pound for butter, this would represent a gain of 

 .|7.{)0 per day or over |2,500.00 per year more profit for the factory- 

 separator creamery than the old method. 



Now the gravity-cream-gathering factory, is considered by many 

 the full equal of the separator factory. It has held right on in many 

 sections in spite of the best competition which the Avhole-milk- 

 separator factory could put up against it. This should then prove 

 that it is as much superior to the old gravit3^-whole-milk creamery, 

 as the factory-separator creamery is superior to the same thing. In 

 other words, it is also, at least, |2,500.00 per year better and will 

 show that much more profit. But it gets its excess profit from 

 something else than the increase of butter yield, for there is no in- 

 crease, as no separator is used. Now if we can combine these two 

 sets ©f advantages so as to get all the profits of each and both of
