VHY SMOKE IS MADE. 



If the reader understands why a torch 

 smokes, why a flat wick is used in a lamp, 

 why a circular burner is provided for the 

 student lamp, why a chimney ia provided 

 for oil lamps, why a fish tail flame was 

 used in early gas lighting, or why a vac- 

 uum bulb is provided for the incandescent 

 lamp; if he understands these things, he 

 will, it is believed, be able easily to see 

 what conditions are necessary for perfect 

 combustion in boiler furnaces. 



If any fuel is to be burned without 

 smoke it must be supplied with the cor- 

 rect amount of air. The torch smokes 

 because the large round wick brings up 

 oil, especially in the center, to which air 

 cannot be supplied. If the air supply 

 through the center tube of our student 

 lamp is shut off, a smoking flame re- 

 sults. The candle with the small wick is 

 ^.n advance over the candle supplied with 

 the large wick. The flame from the flat 

 wick has an extended surface for air 

 supply, while the circular burner not only 

 has maximum surface for air supply, but 

 the air coming up through the center of 

 the tube is heated, making it still better 

 suited to aid combustion and burn a 

 large amount of oil. Thus it is that we 

 have successfully solved the problem of 

 burning a large oil supply without smoke. 

 If we try to increase the oil consumption 

 and turn up our lamps too high, they 

 smoke, and because they are in the room 

 with us we immediately turn them down. 

 Furnaces burning coal sometimes smoke 

 just because they are forced too hard, 

 and because the top of the chimney is not 

 in the room, but in the public's pure air, 

 we do not turn them down but let them 

 smoke. 



Air correct in amount is a necessity 

 for complete combustion and the simple 

 experiments with our oil and gas flames 

 should be sufficient evidence to us that 

 only when we are able to supply our fur- 

 naces with the correct amount of air 

 shall we be able to control the smoke 

 which it is so easy to make. How much 

 easier our problem would be if, as in the 

 lamp, we could see all that was taking 

 place and could regulate all by a simple 

 knurled brass handle! 



INSUFFICIENT BOILER CAPAQTY. 



I have a house 30x70 feet, with four 

 feet of side glass and the ridge at a 

 height of thirteen feet. It is heated at 

 present by a Wilks hot-water heater, 

 30x48 inches, made to heat 750 feet of 

 radiation. The piping consists of three 

 3-inch mains, with twelve 1^-inch re- 

 turns, one coil in the center and one on 

 each side; four pipes to a coil. We are 

 splendidly protected and when the ther- 

 mometer registered 38 degrees below 

 zero we held the temperature at 52 de-

Gemtlkhbn:— You c^ Btroogly and unhesltatiDcrly recommend tha 

 "Eclipse" piston type reducing valve to fiorJsts. We have two purchased 

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

 find them as sensitive as a watch. We will be in Chicago soon to take up 

 the vacuum system with you. Yours truly,

grees, though we thus used an immense 

 quantity of fuel. This year we wish to 

 build a vegetable house, 16x50 feet, with 

 a 2^-foot basement and a low roof. No 

 side glass. This will be at right angles 

 to the other house, and the boiler-room 

 is 80 arranged as to open into both 

 houses. Will our present boiler handle 

 both houses? How much pipe should 

 there be in each house — one house for a 

 temperature of 60 degrees with an out- 

 side temperature of 20 degrees below 

 zero, the other house for vegetables! "We 

 could probably get a good, cheap second- 

 hand steam boiler here. Would it pay to 

 change to steam heat? K. I. M. 



The boiler in question is not quite large 

 enough to carry the present house, 30x70 

 feet, at 65 degrees. The piping is not 

 quite suflScient for this temperature. Six- 

 teen 1%-inch returns, with the three 

 3-inch flow pipes, would make the heating 

 of the house easier. The proposed house, 

 16x50 feet, can be heated by using one 

 2% -inch flow pipe and twelve IV^-inch 

 returns. An additional boiler with 750 

 square feet of heating capacity should be 

 added, however. You would not be jus- 

 tified in changing to steam. You could 

 save a little on piping, but more care in 

 firing would be necessary. Stick to hot 

 water. L. C. C.

The Market 



The first part of last week business 

 was not any too brisk, owing to the in- 

 clemency of the weather, but the latter 

 part, as usual, found stock, especially the 

 kind used for the shipping trade, more 

 lively. It is customary, at any rate, to 

 look for Friday and Saturday as good 

 days, even if the other days are slow. 

 Last week found plenty of all kinds of 

 stock to fill all orders. Sweet peas, which 

 now take the place of the violets, are of 

 fine quality and sell readily. 



Various Notes. 



The Baumgarten Floral Co., which has 

 occupied its present quarters at 320 West 

 Water street for the last twenty years, 

 has found that it has outgrown the place 

 and will remove to a more spacious build-
