Cooley, of Vermont, who invented, or rather adapted it in 187fi. There is not much—if, indeed, there is anything at all—that is new in principle in this system ; it is based on the Swedish ice-water system, which was discovered by !Mr. Swartz many years ago, and which is now almost universal throughout a great portion of Northern Europe. The Cooley system we say is based on the Swartz system, but it has one or two features that are not commonly, if ever, found in the latter; and yet these features are not, if we except one of them, wholly original—if, indeed, that one is. The two features are: first, setting the milk-cans in a lidded box or tank ; and second, in completely sul)merging them, that is, allowing the ice-water or cold sjiring-watcr to flow over the tops of the cans ; this last is the original feature. The milk-cans, as seen in the one in Fig. 157, are round and deep, and have a lid fitting loosely over the top; they have also a tap in the bottom, by means of which the milk can be drawn away from beneath the cream, thereby obviating the necessity of skim- ming the latter off the former. To the tap in the bottom it will be noticed a tube is attached; the tube is of india-rubber, and of course flexible; at the other end of it is at- tached a metal outlet, and this slides in a gro
