The hinges, by which the cover is fastened,are attached to these 2x4 pieces, as shown in Fig. 7.

Fig. 8—Milk and Cream Cooler. cooler consists of two parts: an upper section, which is used for cool-ing milk or cream with uniced water, and a lower section, throughwhich ice water is circulated. By means of the pump at the left, theice water is pumped back in the tin can at the right, which containsthe ice. The well water is admitted to the upper section of thecooler by opening the valve shown at the upper right-hand corner ofthe cooler. On a farm, a barrel or tank elevated to the height of thisvalve could be used as a water storage from which water may bedrawn into the upper section of the cooler. The water in both sec-tions enters at the bottom between the two corrugated surfaces anddischarges at the top, the milk flowing over the outside. As might be expected, by forcing the ice water from the coolerback into the ice water storage, a considerable saving is effected, notonly of ice and water, but of time as well. Proof of these advan-tages is brought out by the results recorded
