DAIRYING 



around the country with a cheap combination of tinware, tubes 

 and a faucet, trying to induce the farmers to buy this "Most 

 Valuable Invention." 



This so-called ''separator" is simply a painted tin can with' a 

 funnel shaped tube on one side of it. Milk is poured into the can 

 through the top cover and water through the funnel tube at the 

 side. The mixture of equal parts milk and water is allowed to 

 stand from "30 to 90 minutes," and then the skim milk is drawn 

 off through a faucet near the bottom of the can. What is drawn 

 off appears to be a very thin skim milk, but as it is more than half 

 water, considerable cream is required to make it even look like 

 skim milk.

258. A great many trials of this dilution method of cream 

 raising have been made at experiment stations. Professor Wing, 

 of Cornell University, has tried three different kinds of apparatus 

 devised for this purpose. He did not get nearly so complete a 

 separation of cream with any of them as was obtained by the 

 centrifugal separator, the shallow setting or the deep setting of 

 the milk in cold water. At 5 farms where these "new" dilution 

 methods of cream separating were used, the skim milk tested from 

 0.66 to 1.20 per cent. fat. At 40 farms where milk was set in
