RUDDICK, Dairy Commigsioner. Department of Agriculture, Office of the Dairy and Cold Storapo Commissioner. Ottawa, January, 1916. During the last 30 years, the commercial extract of rennet, prepared in specinl laboratories, has entirely supcraeded the old fashioned coagulating fluid which tlif eheeeemaker obtained by soaking calves' stomachs in water. In the early days tin- stomachs, or rennets, were procured from the patrons of the cheese factory, but later i; better cured article was obtained from Continental Kurope, an >-iin. Where a fan can be used to create draught, it will help dry the rennets quickly, and the process should not take more than a week. They should not be l(>ft ni;isc l or 50, and pack in cases or barrels. Fresh salted. — When it is not convenient to blow up and dry the rennets, they may be prepared for immediate shipment by splitting open aud salting.

In any ease, it will be necessary to deal with the laboratnries in the T'nited States until such time as the manufacture of extract is started in Canada. The best known laboratories in the United State- are Chr. Ifansen's Laboratory. Little Falls, N.Y., and :Marshairs Dairy Laboratory. Madison, Wis. Tl^ author does not believe that the home made article could be tised witiiout serious injurj- to the quality of our cheese, and these notes are published rather to encouraire the saving of rennets tiian to iiroinote their use by the cheesemakers, but in case it sliould be necessary, as a last resort, for the checsemaker to prepare his own rennet, a few directions will be useful.
