pipes to the fartbor Mid of the,4iouBe, 



where they should be connected with 

 fourteen 2-inch returns. Place one of 

 the flows on each wall plate and the 

 other about two feet below the ridge- 

 Arrange the returns in four coilsjjiwith 

 one coil of four pipes upon each side 

 wall or under the side benches, and 

 the others in two coils of three pipes 

 each under the. middle benches. 



Give the flow pipes a fall of about 

 one inch in ten feet and connect the 

 highest point of each pipe with the 

 pipe leading to the expansion tank. It 

 would simplify matters if 3-inch 

 pipe could be used for the main 

 flow and return pipes to connect 

 the 214-inch flows and returns with 

 the boilers, in which case the' pipe 

 to the expansion tank could be con- 

 nected with the highest point of 

 the main flow pipe. This will do away 

 with all occasion foiC,air valves in the 

 pipes. 



A UTAH OAENATI9N HOUSE. 



I intend to build a greenhouse to be 

 used for growing carnations. The house 

 will run norll\ and south and will be 

 21x100. It will .have concrete founda- 

 tions and will have two and one-half 

 feet of glass in each side. I can buy a 

 boiler here, made by Our Own Mfg. Co., 

 Canton, O., and rated for 1,450 feet of 

 radiation. Will it be large enough to 

 take care of this carnation house in 

 zero weather? Please inform nie, also, 

 how this house should be piped to give 

 the best results. I am a beginner in 

 greenhouse construction. The house will 

 have a full gable end to the north and 

 a half gable to the south, where it will 

 be connected to the -potting shed and 

 workroom. A. P. 



The boiler mentioned should be amply 

 large to heat the house, as but little 

 more than 750 square feet of radiation 

 will be required and a boiler rated for 

 1,000 square feet of radiation should 

 be large enough to handle it. 



To heat the house described to a tem- 

 perature of 50 to 55 degrees in zero 

 weather, I would suggest the use of 

 three 2^ -inch flow pipes, of which one 

 could be upon each plate and the other 

 about two feet below the ridge, and 

 nine 2-inch return pipes arranged in 

 three coils. Place one coil on each 

 wall or under the side benches and the 

 other under the middle bench. Give 

 the flow pipes a slight fall and attach 

 the expansion tank to the highest 

 point, which should be near the boiler. 

 When using a hot water system it is 

 always well to have the boiler so lo- 

 cated that its top will be below the 

 level of the return pipes, as then there 

 is seldom any trouble about securing a 

 good circulation. If this cannot be 

 readily arranged, the circulation will 

 be greatly improved by attaching a 

 mercury generator to the expansion 

 pipe. 



AN ADDITION FOR IJ5TTUCE. 



I am sending you a sketch of my 

 greenhouses, showing the location of 

 the heating pipes, which heat the pres- 

 ent house satisfactorily. The present 

 house is used for violets and I expect 

 to add a house for lettuce. Kindly ad- 

 vise me as to the best way of heating 

 the proposed lettuce house to a tem- 

 perature of not less than 40 degrees 

 at night. I have an upright sectional 

 b«tl«r ftbeut five feet high, with a 



Put It to Yourself This Way 



^HALL I deliberately put my money 

 ^^ into a wrougbt iron boiler that is 

 going to cost me a lot to be retubed in 

 a few years, or shall I buy a cast iron 

 boiler that will last at least a Quarter 

 of a century? 



Shall I put my money into a wrought 

 iron boiler, twice the size I need now. 

 or shall I buy a Hitchings cast iron one 

 the right size, and add more sections to 

 it when I add more houses?

Shall I buy one big wrought iron boiler 

 and be compelled to run all that big 

 grate— no matter what the weather or 

 shall I buy a battery of Hitchings boil- 

 ers and use one boiler when I need only 

 one, and two only when I need two? 



In short, shall I listen to clever sales 

 talk or shall I let my common sense 

 decide it? 



When shall we ship the Hitchings?

HOT WATER- Open tank or pressure systems designed 



by us will heat perfectly and not "blow out." STEAM 



SYSTEMS we design to meet your special conditions. Our 



pump or trap return systems will prove satisfactory in all 



cases where a gravity return is impossible. Our VACUUM systems are 



the last and best word for heating large and modem ranges. We can put
