shape as to respond instantly to the 

 improvement thus indicated." 



In the same hopeful mood the Black 

 Diamond gives its views with special 

 reference to Chicago and vicinity, as 

 follows: "The technical situation of 

 the smokeless market has been im- 

 proved within the last weekt At this 

 time a week ago it was not sure wheth- 

 er the circular price was going to hold 

 either on spot business or on contract. 

 There was so little buying by the retail 

 dealers and others that off-grade coals, 

 sold at a big reduction from circular 

 price, about dominated the market. 

 This seemed to establish the market on 

 an extremely low level, at which $1 per 

 ton was a fair price and 90 cents per 

 ton at the mines on mine-run coal not 

 an uncommon price. These low prices 

 were due to an- accumulation of con- 

 signment coal which had to be moved 

 and the situation was relieved by the 

 withdrawal of that consignment coal 

 in large quantities from this market." 



PIPING TWO OHIO HOUSES. 



Enclosed you will find a sketch of a 

 greenhouse, 26x50, running north and 

 south. The height of the house to the 

 ridge is fourteen and one-half feet. The 

 side walls are six feet high and con- 

 sist of two feet of concrete and four 

 feet of glass. The gable ends also 

 are glass, but the north end is partly 

 protected by another building. At pres- 

 ent we are heating the house with two 

 flues, one under each side bench and 

 running the entire length of the house. 

 The fireplaces are in a pit under the 

 level of the benches. However, we con- 

 template building another house, a du- 

 plicate of the present one and stand- 

 ing alongside it, and we are planning 

 to install a hot water system of heat- 

 ing. Will you kindly state what horse- 

 power of boiler will be needed for the 

 two houses? Please state, also, the 

 right number and size of pipes and the 

 best arrangement of them. The dis- 

 tance from the floor of the present pit 

 to the eave plates is eight feet. Can 

 this pit be used for the boiler to stand 

 in? 



We expect to have the two houses 

 connected by taking out the west wall 

 of the present house, thus converting 

 them, practically, into one house, with 

 a total area of 52x50 feet. At some 

 future time, also, these houses may be 

 extended to a length of eighty feet, 

 but we wish to be as economical as pos- 

 sible at present. We should like to be 

 able to keep a night temperature of 55 

 to 60 degrees. In this part of Ohio the 

 thermometers outdoors have occasional- 

 ly registered from 15 to 22 degrees be- 

 low zero. H. B. 



For the two houses 26x50 feet, each 

 of which will have four feet of glass 

 in one wall, not far from 1,200 square 

 feet of radiation will be required, and 

 the boiler should have a rating of 1,500 

 square feet of hot water radiation. 



To heat these two houses, I would 

 suggest that 2%-inch flow pipes be run 

 about three feet below each ridge and 

 also upon the plate of the outside wall 

 of each house. There should be a fifth 

 pipe upon the middle wall, between the 

 houses. These can be extended and 

 will answer for houses eighty feet in 

 length. Use six 2-inch return pipes 

 upon each of the outer walls and con- 

 nect six returns to each of the flow 

 pipes under the ridges of the houses. 

 To the flow pipe on the center wall con-

O^^t^ 



The immense amount of direct self- cleaning: heating: surface and 

 the thin vertical waterways cause this type of boiler construction 

 to heat water quicker than any other form of boiler. 



Hundreds of Florists' Review readers are using the 

 Kroeschell Boiler and mighty is their praise. The 

 year of 1913 has brought us an enormous number of 

 new customers who have seen our boiler in operation 

 at other places. We attribute the large sales of tkis 

 season to the good work the Kroeschell Boiler is doing 

 everywhere. With our policy — "the customers' interest 

 first" — perfection of construction — factory to user 

 prices — honest and "true blue" boiler ratings — you 

 simply cannot lose.
