holding for $1.25 have had practically 

 no free coal for sale, the disposition 

 of a small amount of free coal at $1 

 per ton has about established the mar- 

 ket at that figure." 



MATERIAL FOB SMOKESTACK. 



We should like to get some advice in 

 regard to building a stack for our boil- 

 ers. Several persons here have sug- 

 gested that we build it of brick up to a 

 height of twenty feet and then build 

 the additional forty feet of sewer tile. 

 "We should like to know whether anyone 

 has tried this kind of stack, or whether 

 it would be advisable to build in this 

 manner or to build entirely of brick. 



J. H. T. 



The size of tlie chimney has much to 

 do in dete.rmining the material of which 

 it should be constructed. When it is 

 more than two feet in diameter I would 

 always use brick or concrete, but for 

 those between one and two feet in diam- 

 eter the relative cost of the two ma- 

 terials at a given locality would deter- 

 mine whether a brick or a steel stack 

 should be used. A properly constructed 

 brick or concrete stack is far more 

 durable than a steel stack and is gen- 

 erally preferred. So far as the value 

 of sewer pipes for chimneys is con- 

 cerned, while they might be used for 

 small chimneys, eight to twelve inches 

 in diameter, and where not over twenty 

 feet of tile is used in a chimney thirty 

 feet high, I 'would not care to employ 

 them in the construction of either large 

 or tall chimnevs. 



INSULATING UNDERGROUND PIPE. 



I intend to heat my dwelling house 

 from my greenhouse boiler, using hot 

 water under mercury pressure. The 

 boiler is 22/5 feet from the residence. 

 Please describe the best method of in- 

 sulating the flow and return pipes, so 

 as to lose the least possible percentage 

 of heat in transmission. R. M. G. 



One of the simplest methods of in- 

 sulating underground heating pipes is 

 to cover them with ordinary asbestos 

 wrappings, and then, as each length of 

 pipe is connected, slip over it sewer 

 pipe which is about three inches larger 

 than the heating pipe after the wrap- 

 pings have been put on. 



Every twenty feet provide some pipe- 

 support which will allow the pipe to 

 expand and contract. A simple form 

 consists of pieces of ^A-inch round iron, 

 with the ends flattened so that they 

 will fit into the joints of the tile. By 

 slipping over these rods, after one end 

 has been flattened, short pieces of %- 

 inch pipe which will act as rollers, the 

 movement due to the expansion and 

 contraction of the pipes can be provided 

 for. Either strips of iron should be 

 firmly wired to the under side of the 

 pipes wherever there is a roller, or a 

 little of the wrapping should be cut 

 away on the under side so that the pipe 

 may rest upon the rollers. 



For larger pipes, or where sewer pipe 

 would be expensive, a square concrete 

 conduit large enough to hold both heat- 

 ing pipes, and covered with concrete 

 slabs, may be constructed.

Painesvllle, O. — C. Merkel & Son have 

 started the erection of another large 

 greenhouse, at the south end of the 

 range. This is as far as the establish- 

 ment can spread in this direction.
