On page 15 of this issue is an illus- 

 trated description of W. H. Gulp's suc- 

 ■cessful oil burner which will be of spe-

ONE MICHIGAN HOUSE. 



I have one new house, 22l^xl50 feet, 

 five and one-half feet high at the sides 

 and twelve feet high in the center. 

 The beds are all solid. Can I heat this 

 house to a temperature of 45 degrees, 

 when the outside temperature is 10 de- 

 grees below zero, with two 3-inch flows 

 and four 2-inch returns? Where is the 

 best place in which to put the valves, 

 on the flow or on the return? Should 

 the expansion tank be connected to 

 the return, near the boiler? I -want to 

 run the flows and returns downhill. Is 

 that right? I am enclosing a plan of 

 the house. J, G. 



The sketch shows one 3-inch flow on 

 each purlin post and two 2-inch- returns 

 on each wall, near the gutters. The 

 house evidently has about two feet of 

 glass in one side wall. The other wall 

 is protected by the adjoining house. 

 The plan is an excellent one, but it 

 will be well to have two additional 

 2-inch returns, which could be turned 

 on in severe weather. Another way 

 would be to use two 2V2-inch flows and 

 seven 2-inch returns, placing the extra 

 flow on the exposed side of the house. 

 Bun all pipes downhill. Connect the 

 highest part of each flow with the ex- 

 pansion tank and place the valves on 

 the main returns. 



BUBNS TOO MUCH COAL. 



I should like to know what is the 

 trouble with our boiler. It does not 

 hold the pressure over fifteen to twen- 

 ty-five minutes. It is a forty-five horse- 

 power tubular boiler, with a grate 

 forty-eight inches square. It has a 

 3-inch feed, supplying steam to twelve 

 beds. Connected with this main feed 

 pipe, there is a 1-inch feed for each 

 bed, leading into two IVt-inch returns, 

 then into a li/{;-inch main return back 

 into a receiver and from there into a 

 Morehead return trap. There are three 

 greenhouses, each 27 x 100 feet, seven 

 feet to the gutter and sixteen feet to 

 the ridge. There is considerable steam 

 coming out of the exhaust of the trap. 

 Should this exhaust be open at all 

 times, and could we aid in the saving 

 of coal by having this live steam go 

 into the ash pit? 



We burned last winter three carloads 

 of coal, each car containing fifty tons. 

 We have to shovel coal on about every 

 half hour, besides having the drafts 

 wide open. Our chimney is forty feet 

 high from base to top. We burn Poca- 

 hontas mine run and have the coal well 

 saturated with water. Could you give 

 any advice as to how to fire a boiler of 

 this kind? W^e should like to know
