Creenhouse Heating. 



SuBSoaiBEBS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Beview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 beheve, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



THE COAL MAEKET. 



The coal market during the last 

 week or two has shown a slight gen- 

 eral improvement in tone, partly due 

 to the cool weather in March, Nearly 

 every dealer has had a little increase 

 in business and this has had the imme- 

 diate result of quickening operations 

 somewhat at the mines, for there is 

 practically no free coal to take care- 

 of any rush of orders. As soon as buy- 

 ing increased, it was necessary to en- 

 large the output at the mines. "Smoke- 

 less coal," says the Black Diamond, 

 'has shown an improvement both in 

 spot buying and in sales for future 

 delivery. While prices are at the 

 lowest level of the year, there is some 

 little interest also in contracting and 

 reports are that some tonnage has 

 been placed among retailers and among 

 dock interests in the northwest. Con- 

 tracting is not yet as lively as it has 

 been in other years, but an improve- 

 ment is noted in that direction. The 

 price of mine-run smokeless, f. o. b. the 

 mines, is .$1 to $1.2.5." 



FIEST PEINCIPLES OF PIPING. 



You've heard of the fellow that 

 "didn't know twice." Well, that's 

 yours truly. I am simply "up in the 

 air" as to my heating arrangement. 

 Some say to run my flow through the 

 center of the house, two or three feet 

 below the ridge; others say to run it, 

 or them, along the plates; still others 

 say that by all means I should use 

 large, say 4-inch, pipes for both flows 

 and returns and put them all under 

 the benches. 



Xow, I can't see any sense in deliv- 

 ering a large percentage of the hot air, 

 and the hottest of it at that, at the top 

 of the house, where it is not wanted, 

 where it will do no good, but where, 

 alas, it will quickly go anyway — more's 

 the pity. Neither can I see any sense 

 in using a 4-inch pipe or pipes (one man 

 is using" three 4-inch flows and the same 

 returns under each bench), and feeding 

 the whole shooting match with a 2-inch 

 or 21^-inch pipe from the boiler. 

 Another thing that gets my goat is 

 that one says, "Be sure your flow is 

 highest at the farther end from the 

 boiler," and the next one says, "Rise 

 to your extreme height at the boiler 

 and let the flow fall as it goes toward 

 the farther end of the house." "When 

 the doQtors disagree," etc. 



I am building a little house, a mere 

 playthinfirier size, as you would likely

term it — only 18x50, with 6-foot side 

 walls, glass in one end, the other end 

 attached to the boiler house. I shall 

 probably use a Wilks boiler and I want 

 to pipe the house in the best way and 

 at the same time the cheapest way. A 

 temperature of 60 degrees at zero is 

 all right, but how about 30 degrees 

 below, as it sometimes gets here? 



Now, somehow I have considerable 

 confidence in your opinion (foolish, too, 

 isn't it? I used to be a newspaper man 

 myself), and I shall much appreciate 

 it if you will advise fully just how to 

 arrange my heating system, for, as I 

 said at the start, "I don't know twice" 

 about the matter. F, G. — 111.
