ings with an even greater unanimity 

 than it has been adopted by florists. 

 Also, the landlords know the advan- 

 tages of summer buying, so that the 

 market is steadier than it used to be. 

 Last season's low prices were the re- 

 sult of unlooked for circumstances; the 

 advance this season is not so great as 

 it seems. Perhaps it will interest some 

 of the growers who buy in carloads 

 f. 0. b. the mine to note the prices 

 the flat buildings pay in Chicago for 

 Pocahontas, run of mine: Present de- 

 livery, $4.25; winter contracts, after 

 October 1, $4.50; lump, forked clean, 

 $5.50 per ton. Pocahontas lump is 

 scarce, but there is no shortage of 

 mine run. 



AN ILLINOIS VEGETABLE HOUSE. 



I intend to build a greenhouse, 32x 

 100, to be used for growing lettuce or 

 parsley. Will you kindly state the 

 amount of piping that will be necessary 

 to maintain the proper temperature 

 when the outside temperature is 15 de- 

 grees below zero! E. C. S. 



The question does not give a suffi- 

 ciently definite idea of the house, and it 

 makes considerable difference how high 

 the walls are and how much glass they 

 contain. If the walls are not more than 

 five feet high and contain no glass, the 

 house can be heated by means of three 

 2%-inch flows and twelve 2-inch re- 

 turns, using hot water, or one 2%-inch 

 flow and ten 1^-inch returns, using 

 steam. • With two and one-half feet of 

 glass in each wall, two additional re- 

 turns would be required. 



The amount of pipe required for hot 

 water heat would be 300 feet of 2%- 

 inch and 1,200 feet of 2-inch. For 

 steam the amount would be 100 feet 

 of 2^-inch and 1,000 feet of li4-inch. 

 If there is as much as two and one-half 

 feet of glass in each side wall, 200 feet 

 more of pipe will be required.

Hake Your 

 Boiler an Asset, 

 Not a Liability 



- A boiler costs enough so that every florist should be anxious to 

 ge^the most possible for his money ; he should closely investigate sev- 

 eral Btylea before choosing. The more you investigate the m«re sure 

 it is that you'll buy the Superior Standard. It was designed spec- 

 ially for greenhouse ^ork after a close study of what was needed. It 

 is easily cleaned, although it has more flues than any other boiler, but 

 —more flues give more heat ; more flues require less fuel ; the water 

 heats quicker and hotter because the volume of water heated by each 

 flue is smaller. All we ask is a chance to show you.
