A Steady 

 Pressure 



will always 

 be main- 

 tained in 

 your steam pipes, no matter 

 now the pressure at the boiler 

 fluctuates, if you equip your 

 main lines with these valves. 

 Garry 40 or 60 pounds pressure 

 on the boiler, set the 



Hughson 

 Regulating Valve 



to carry 5 or 10 pounds on the 

 line and you will always have a 

 reserve in case of a sudden drop 

 in temperature. This valve 

 saves both fuel and worry. Ask 

 for catalogue and pUrticmars.

2-inch returns. Our boiler is six feet 

 long and thirty inches in diameter. It 

 is a shell filled full of' 2-inch flues. We 

 believe there are seventy-six flues. The 

 boiler is set in brick. The coldest out- 

 door temperature is about 25 degrees 

 above zero. We use oil (distillate) 

 for fuel. We can not seem to get the 

 desired heat when we have continuous 

 cold weather. Would a larger boiler 

 heat up the pipes better? Is that a 

 good style of boiler for' hot water, or 

 would a regular steam boiler be better? 

 How do you figure the heating capac- 

 ity of a boiler for hot water? The 

 reason we use a shell boiler is that we 

 think that when using oil it gets the 

 heat distributed through the water bet- 

 ter. E. O. H.

The size of your boiler is all right 

 and the style* is good, as it has a large 

 heating surface. Keep the boiler flues 

 clean and the water in the system 

 clean, and it should work satisfactorily. 

 The boiler has nearly its capacity. 

 Give the boiler a good cleaning, and 

 next winter push it in good shape, and 

 it will heat all right. 



In regard to the heating capacity of 

 a hot water boiler, figure twenty-two 

 square feet of radiation for every 100 

 square feet of glass, multiplied by 1.5. 

 Divide this by 125. The answer found 

 will be the grate area. Eatio of your 

 style, boiler in heating surface to grate 

 area is twenty to twenty-five. F. E. 



THE FUEL SITUATION. 



It appears that the settlement of the 

 anthracite miners' wage controversy 

 will have little if any effect on steam 

 coals, but that the average price of the 

 domestic sizes of anthracite will be in- 

 creased about 25 cents a ton as a result 

 of the wage increase granted to the 

 mine workers, who have just resumed 

 work after forty-four days of idleness. 



According to calculations at the time 

 the mine workers presented their de- 

 mands, those demands, if granted, 

 would have increased the cost of pro- 

 duction of all sizes of anthracite 40 

 cents a ton, and, since the competition 

 of soft coal makes impossible an ad- 

 vance in the price of the steam sizes, 

 the added cost of production would have 

 been covered by advancing the price of 

 the domestic sizes, which comprise sixty 

 per cent of the total production, 66% 

 cents a ton. But the mine workers and 

 operators reached a compromise agree- 

 ment which provides for a wage in- 

 crease not as great as that originally 

 demanded. From the books of the com- 

 panies it is calculated that a price ad- 

 vance of about 20 cents on domestic 

 sizes will be required to cover the wage 

 increase finally granted. The balance 

 of the price advance of 25 cents will go 

 toward making up the increase in the 

 cost of production, aside from labor 

 cost, that has taken place in the last 

 ten years. There has been no general 

 advance in the price of anthracite since 

 1903. 



The spot prices of bituminous coal are 

 about at the usual end-of-May level. 

 Contract prices are slightly advanced, 

 because of the boost given the miners' 

 wages. 



Athens, Ga. — Thomas Pennock has 

 taken charge of the Cruse gardens here. 

 He came from Gainesville, Ga., where 

 he had for more than six years been

Where We Stand on 

 Boilers and Heating 



FIRST let U8 tell you where we 

 stand on boilers ! 

 For ranges up to a certain 

 size it has been proven time 

 and time again that the most econ- 

 omical boilers to use are our cast 

 iron ones. This applies to both 

 water and steam systems. Having 

 proven this so conclusively, we 

 quite naturally stand by the proof. 



When, however, ranges exceed 

 what we call an "Economy limit," 

 we promptly advise the use of 

 wrought boilers. In such cases we 

 will either furnish such a boiler for 

 you or suggeft the best ones we 

 know in the field. 



So much for the boiler— now 

 for the various Heating Systems. 



Here, again, enter the same 

 economy proofs that must and do 

 guide us in endeavoring to guide 

 you. It's simply a case of the sys- 

 tem best adapted to your particular 

 needs. Whether that be a question 

 of water, steam, gravity, or me- 

 chanical circulation, and so on, 

 matters not to us. 



in tal(ln|r our advice on Heat* 

 ins tiiere's also this to remem- 

 ber: We were the first heating 

 engineers to enter the greenhouf-e 

 heating field. We installed green- 

 house heating itself a good many 

 yearc before we started building 

 greenhouses. 



It stands to reason, then, that 

 our sixty years' experience, back - 

 ing up our present up-to-date ideas 

 and actions, is a mighty valuable 

 thing for you to get the advantage 

 of. 



Our prices are such as must of a 

 surety alwajs be asked fo;- materials 

 of the best, combined with work- 

 manship by the high(>8t pkilled 

 heating men in the business. 



If you want this kind of work— 

 you want ua.
