By nsin? all of the present pipes as ?ttuin'-. iiinl rnnninp two 2V-;-inch flows overhead, but with a slight fall, to the farther end of the house, where ? ach should be connected with the four pipes on one side of the house, a tem- perature of 50 degrees can be obtained. One 3-inch flow and one 3-inch return can be run to each house and con- nected with the pipe just specified. While only 600 square feet of radia- tion will be used, it will be well to use a boiler rated at about 1,000 square feet. To heat a dwelling 30x30 feet would vequire from 300 to 500 feet additional, -iccording to the thoroughness with which it is heated.

It is a hori- zontal, tubular boiler, ten feet long and thirty-six inches wide, with a firebox thirty-six inches square. At the east end of the south house there is another boiler, in a 3-foot pit. This one is a 10-section, cast-iron boiler, five and one-half feet long, four and one-half feet high and three feet wide, with a tirebox lSx42 inches. I heat the north house and half of the middle house with one boiler, thf rest with the other boiler. The north l)oiIer has a 4-inch flow until it reaches the house, then two 3-inch flows to the far end, dropping down and coming back in coils under the benches. The rrturns have about one foot of fall, and when they reach the boiler are still above the top; they drop down along side the boiler to the bottom, with 4
