PART HI.— EXPERIMENTAL DAIRY WORK. 



The experimental dairy building on the farm, which was described in the annual 

 report for 1890, was completed early in 1891. A cut of it appears underneath. 



The machinery and apparatus are adequatefor the present needs of thefarm, and 

 enable us to carry on investigations which are considered to be capable of rendering 

 the most immediate and practicable service to the dairymen of the country. 



An 8 h. p. boiler and 6 h. p. steam engine were purchased from Mr, Geo. Low, 

 of Ottawa, who also fitted up the steom pipes and shafting throughout the building. 



A hand-power centrifugal cream separator, manufactured by Burmeinster & 

 Wain, of Copenhagen; 



A Xo. 4 " Alexandi-a" centrifugal cream separator, and a No. 8 "Alexandra" 

 centrifugal cream separator for operation by hand-power, manufactured by R. A. 

 Lister & Co., Dursley, England ; 



One No. 5 Daisy revolving barrel churn of fourteen gallons' capacity, and two 

 No. 2 Daisy churns of four gallons capacity each ; 



A Boj'd ci-eam ripening vat, and fermentation starter vat; 



A lever butter worker for hand use; , 



Several Babcock milk-testers ; * 



Two pairs of weighing scales ; and the usual outfit of small dairy utensils, such 

 as deep-setting milk pails, 20" x 8^" diam., shallow milk pans, strainer, skimmer, 

 butter printer, thermometers, water pails, hot water and cold water tanks, washing 

 sink, brushes, etc., furnish the dairy with conveniences for carrying on its work.

Besides these, there are several tables, and a milk-setting tank which merits 

 particular description for the information of farmers. The tank is constructed of 

 2-inch pine lumber; its length is 7 ft. 6 in. ; its width 2 feet, and its depth 2 feet. 

 These are inside measurements. It is divided into four compartments, each 21 x 24 

 X 24 inches. That size gives sufficient space for the setting of four deep-setting milk 

 pails in each. Cold water is led into each compartment b}^ means of a pipe which 

 runs down to within 1 inch from the bottom. The overflow of water — when it has 

 been slightly warmed by contact with the milk-pails — is carried off by a pipe at its 

 surface. Where the supply of cold water is limited, this method of leading the cold 

 water to near the bottom of the tank, and conducting the water which has been 

 waimed from the surface to the overflow pipe or drain, will enable the cooling 

 power of the water to be used most economicall3\ The overflow watei" may be in 

 excellent condition for the watering of stock, where and when water for both pur- 

 poses is scarce.
