IhfSlPERlriR 



IMPROVED INTERNAL-riRED STEEL BOILER ( 



Made in 10 sizes, to heat from 2000 to 6500 feet of 4-iach pipe. 

 No brick-wotk necessary; shipped on skids, all ready to move into 

 place and befin firing. Can be cleaned without letting the fire out. 

 All hubs made so they can be used for either cast-iron or steam pipe. 

 Tested at 25 lbs. pressure and warranted; can be used for low pressure 

 steam by adding steam drum. Best material; best workmanship. 

 Specially designed for greenhouse use; corrects the faults of other boilers. 

 Lightest boiler on the market capable of performing equal work. W^e 

 dely competition in prices on any boiler of equal capacity. 

 Investigate. Send for new illustrated catalogue, just out.

under the ridge to supply nine 1 14 -inch 

 returns, three under each bench, will 

 probably be ample. If the five houses 

 are parallel, you might construct a 

 cover house or shed across the end and 

 carry a 5-inch pipe past two houses, 

 then reduce to 4-inch and carry to the 

 end of the shed. Prom the main riser 

 take oflf a 2-inch flow for each house, and 

 have a common return parallel with the 

 main flow, into which all the separate 

 returns from the individual houses can 

 be emptied. Make each house just as 

 independent as possible. L. C. C. 



A QUESTION OF CIRCULATION. 



If a steam boiler is sunken below the 

 level of the greenhouse floors and car- 

 ries forty pounds steam pressure, and 

 all returns are connected to the bottom 

 of the boiler, will the condensed water 

 return and feed back into the boiler? 

 All returns will have two feet of fall in 

 100 feet. Will the pressure equalize, the 

 flow lines having only steam in them 

 while the returns will have some steam 

 and the condensed water? The only 

 question to me is: If the steam throt- 

 tler is opened first and the lines become 

 charged, and then the return valve is 

 opened at the bottom of the boiler, will 

 the condensed water flow into the boiler 

 from the lines, or will the water rush out 

 from the boiler into the lines as it would 

 from a blow-off valve? My opinion is, 

 it will until they would become equal- 

 ized. Then, after being equalized, will 

 it flow into the boiler as fast as it would 

 evaporate out in steam? Some have 

 claimed it will work quite satisfactorily, 

 as the water would seek its level, i 

 have natural gas for fuel, and if I can 

 so arrange it I. will save a lot of close 

 watching, •■ J. H. H. 



If the water line in the boiler is two 

 feet or more below the returns under the 

 benches in the greenhouse, and the re- 

 turns are properly graded, there will be 

 no difficulty regarding a circulation. The 

 deeper the boiler can be placed the bet- 

 ter, however. It will be an added safe- 

 guard to place a swing check-valve in 

 the main return, to prevent the water

Ukntmsmen:— You can BtroDgrly and untaesitatlntrly recommend ths 

 "Eclipse" piston type re<luclnf valve to tlorlats. We have two purchased 

 of you last year. Ws would not have them out for double their cost and 

 find them as senHitlve as a watch. We will be In Chicago soon to take up

being backed out of the boiler in case 

 the main flow pipe valve should be closed 

 when the return was open and the steam 

 pressure running up. This would be cer- 

 tain to cause trouble unless the check 

 was there to hold the water in the boiler.

A CEMENT VATER TANK. 



I am greatly in need of a water sup- 

 ply to water my greenhouses and lawn 

 and also for irrigation, and would like 

 your advice on a good quality of tank 

 to use. What I want is a cement tank, 

 and I would like to know if such can 

 be had. My well is on the level of my 

 greenhouse benches, and near the well 

 is a space, about 10x14 feet, where the 

 tank could be placed, and where it would 

 rest on a solid foundation of rock and 

 clay. This is the highest point on my 

 farm. The well is fed by springs, and I 

 could have a continuous flow of an inch 

 to an inch and a quarter, or perhaps 

 more, without lowering it. 



What is your opinion on the best wind 

 tower to pump the water? There is a 

 good current of wind here almost any 

 time. It isn't al)Solutely necessary to

have a high tower, as we are on a high 

 point. What size could be used? Could 

 I use this kind of water supply to water 

 five acres of land, lying west of the 

 tank and on the slope? 



What kind of workman would be re- 

 quired to put up a cement tank? I have 

 grout sand handy for this, if it can be 

 used. What size of flow pipe would be 

 needed? W. C. W. 



Your proposition is to build a con- 

 crete tank on the surface of the ground, 

 which is a hilltop, and pump water for 

 irrigation purposes by wind power. The 

 concrete tank can be easily constructed 

 by placing a concrete floor or bed upon
