THE CARE OF MILK. 233 



sity of setting the milk at all, whether in pans or in 

 deep cans, with all the trouble, time and cost incident 

 to that so far necessary and risky process. Herewith we 

 give engravings of this new dairy machine, which prom- 

 ises to make a revolution in our dairy practice (figure 32). 

 It was first exhibited at the great English dairy fair, at 

 Kilburn, where it obtained a silver medal, and at Haar- 

 lem the Agricultural Society awarded it a silver-gilt 

 medal. Its inventor claims for it the following advan- 

 tages : The cream can be separated from the milk as 

 soon as it is drawn from the cow and aired ; the use of 

 ice is unnecessary; there is no setting of milk for the 

 cream to rise ; all the cream is taken from the milk, and 

 the production of butter is consequently increased ; the 

 skimmed milk is perfectly fresh, and may be used at 

 once for any desired purpose, without loss of sweet- 

 ness ; the quality of the butter is improved, as the 

 cream is separated in a perfectly pure condition ; the 

 process is easy and simple ; the machine is easily cleaned; 

 lastly, the separation of cream may go on continuously 

 so long as fresh milk is poured in and the skimmed 

 drawn out. The operation depends upon the principle, 

 that in a rapidly revolving vessel the heavier contents 

 are forced, by the action of their weight, to the outside, 

 while the lighter gather in the center. The work is done 

 as follows : The receiver, which is made of steel, and is 

 supported by a vertical axis turned by a pulley 6,000/in 

 a minute, is filled with milk, by means of a funnel, 

 which passes into the chamber, through the central col- 

 umn (figure 33, a, which shows its interior arrrangement). 

 The rapid rotary action immediately begins to sepa- 

 rate the heavy milk from the light cream, and in a short 

 time the outer layers of milk are completely separated. 

 As the fresh milk is poured in, this separated milk is 

 forced by it into the tube, h, and arrives through it into 

 the chamber, B, from which it escapes by a pipe. The
