direction of arrows on plan No. i. In the corner of the ice 

 room should be built a 3 ft. by 4 ft. by 8 ft. deep, or larger, 

 cement tank, flush with the floor to catch the water from the 

 ice which can then be pumped to the cream vats for cooling pur- 

 poses. This tank must, of course, have an overflow connected 

 with a trap to the sewer. Two 1% inch galvanized pipes should 

 be laid in asphalt and granulated cork 4 ft. below the floor, and 

 connect with a pump to the cream vats drawing from the bottom 

 of the tank and returning at the surface. If the water in the 

 tank is not sufficient to cool a large amount of cream, ice should 

 be placed in this tank instead of bringing it into the creamery, 

 shaving it up, and putting it in the cream vat. 



A cheaper floor can be used for the ice room temporarily 

 and give fairly good results. First, lay 5 or 6 rows of 4 inch 

 drainage tile 12 to 18 inches below the floor line so that the 

 weight of the ice will not crush them, connecting same together 

 and then with trap to the sewer ; then cover the tile with cinders 

 or gravel, and then place a liberal layer of coarse hay, straw, ex- 

 celsior, or sawdust on top. The water will in this case soak 

 through the hay, gravel, tile, and then into the sewer. The 

 ice water tank should still be there and ice placed in the same for 

 cooling cream, but it would not need to be down in the ground 

 nor quite as large. 



The threshold of the refrigerator should be from 3 to 4 

 inches higher than the creamery floor with long slope so trucks 

 may be used, and then a quarter inch to the foot slope of the re- 

 frigerator floor from door to the farthest off corner with small 

 bell trap connecting to the sewer. The object of the high 

 threshold is to keep that point as dry as possible as all good re- 

 frigerator doors have one or two inch felt pads at the bottom 

 to make the door fit tight, and this loses its insulating value and 

 wears faster when wet. A small door connects the refrigerator 

 with the ice room. This door can be made from single 7/% inch 

 boards and only needs to fit moderately tight. This door must 

 be kept closed in order to have proper circulation. 



A small window with 6 or 7 sash should be placed by the 

 ceiling of the ice room to give light. Another window must be
