ered, are diflScult of explanation. Little 

 wonder, then, that most buyers and 

 sellers feel freer in the absence of 

 agreements, fair dealing being the sole 

 reliance. 



The present prices for the western 

 bituminous coals, mine run, are perhaps 

 5 cents to 7 cents above the correspond- 

 ing date last year. This is not quite 

 so much as the wage advance to the 

 miners. In other words, the mine op- 

 erator is not doing so well at present 

 prioes as he was last year at lower 

 prices. 



Not so in the anthracite fields. Here 

 the price is 25 cents per ton abpve a 

 ye^ago and it more than offsets the 

 advance in wages, but the operators 

 claimrit no more than reimburses them 

 for other extra costs. 



Pocahontas is a favorite fuel for flo- 

 rists. Last year the circular price was 

 $1.10' to August 1 and $1.20 after that 

 date.' But the prices were not main- 

 tained. This year the circular price is 

 $1.10 to August 1 and $1.25 after that 

 date, with nothing in view at the mo- 

 ment to indicate that the circular prices 

 will not be maintained. By circular 

 prices, the coal trade refers to prices 

 to dealers. Florists usually buy at 

 dealers' prices. 



COAL, COKE OB GAS? 



Can you furnish information in re- 

 gard to the relative heating value of 

 hard coal or coke and natural gas, 

 assuming either to be used in the return 

 tubular type of boilers and under nor-' 

 mal conditions? The gas is under a 

 pressure 'of one and one-half to three 

 ounces. The ruling prices in this vicin- 

 ity are: Hard coal, $6.25; coke, $3.50; 

 gas, 30 cents per thousand feet. 



H. O. 



The results obtained when the fuel is 

 used under a tubular boiler might be 

 different from the results as they have 

 been determined in a small sectional 

 heater. In the latter case the coke 

 would be the cheapest of the three fuels 

 at the prices mentioned, but this would 

 require that it be so burned as to secure 

 its full efficiency. Gas would need to 

 be available at 20 cents to equal the 

 price of coke, and at 25 cents to be 

 comparable with the price of hard coal. 

 In favor of the gas should be noted the 



Make Your 

 Boiler an Asset, 

 Not a Liability 



A boiler coats enough bo that every florist should be anxious to 

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

 eral styles before choosing. The more you investigate the more sure 

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

 ially for greenhouse work 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. <
