fireeohoose Heating. 



There is less probability of a strike of 

 coal miners April 1, but it will be just as 

 well to have the sheds full on that date. 



The railroads are planning to advance 

 the freight rates on coal, and of course 

 the man who runs a greenhouse will have 

 to stand for it. 



One of the large growers for the Chi- 

 cago market, head of a firm that has ap- 

 preciated the importance of the heating 

 plant as related to the season's profits, 

 after spending a good deal of money in 

 trying out various devices, says he con- 

 cludes there is nothing so good to make 

 steam as Pocahontas coal burned on the 

 close-set bars of the Martin rocking grate. 



UNDERGROUND SMOKE FLUE. 



My experience with an underground 

 smoke flue may be of interest to W. H., 

 whose inquiry appears on page 84 of the 

 March 3 issue of the Keview. 



Almost eighteen years ago, I thought 

 it would be a good idea to run a flue 

 underground and cover it over with hot- 

 bed sash, so as to get an early .start with 

 lettuce and radishes. I bought fifty-six 

 feet of 9-inch vitrified tile, laid them out 

 in the field with a good rise and cemented 

 the joints perfectly tight, as I thought, 

 but almost at once had to punch a hole 

 in the bottom of the joint next the boiler 

 to let out the water. 



At the outer end I built a wooden 

 chimney about sixteen feet high and on 

 top of that almost as much more hot air 

 furnace pipe. I had a small, upright 

 boiler with horizontal sections and it 

 needed extra good draft. In sharp, 

 frosty weather it worked fairly well, but 

 a day or more before a thaw, the thing 

 would smoke so badly that the fire would 

 only smoulder, so that, between the risk 

 of freezing and destruction by coal 

 smoke and gas, I was in a bad way. 



I don't think it is worth while trying 

 to make a flue work underground. There 

 must be a certain degree of heat in the

flue, something like 300 degrees, if I 

 remember right, and it would be almost 

 impossible to maintain that temperature 

 with the flue in contact with the cold 

 ground; the dampness alone would al- 

 most put it out of business. If it could 

 be boxed in, dry and clear of contact 

 with the cold ground, it might work, but 

 I don't think it would pay to try it.

STACK VITH NATURAL 



I have a thirty-five horse-power boiler 

 of the locomotive type. It contains 

 thirty-six 3-inch flues, eight feet long. 

 I burn gas in the fire-box, but the blaze 

 does not go in about the flues, as there is 

 no smokestack on the boiler. I am plan- 

 ning to erect a stack, thirty feet high, 

 this summer. What per cent would I 

 save in fuel by using the stack? 



C. B. 



Without knowing more about the pres- 

 ent arrangement of the boiler, a definite 

 answer cannot be given to the question

regarding the probable benefit from using 

 a stack thirty feet high upon a locomotive 

 type of boiler for burning natural gas, 

 but it is probable that the eflBciency of 

 the boiler could be increased fifty to 100 

 per cent. However, it is doubtful whether 

 a boiler of the size mentioned can be 

 made to develop thirty-five horse-power. 



TWO WEST VIRGINIA HOUSES. 



Please let us know how much pipe will 

 be needed to heat one greenhouse, 50x200 

 feet, to grow carnations, and one house, 

 25x200, to grow roses, in zero weather. 

 The houses will have 3-foot concrete walls 

 and four feet of glass, making the walls 

 seven feet to the gutter. The concrete
