will be proportionately more or less than 

 the number of tubes. In other words, if 

 there are fifty tubes three inches in 

 diameter and twelve feet long, the boiler 

 would be rated at forty horsepower. 



Another way of expressing the same 

 thing is to estimate the horsepower of a 

 boiler as equal to the number of flues, 

 multiplied by the diameter of the flues 

 in inches, multiplied by the length of 

 the flues in feet, divided by 45; thus, 

 50x3x15 divided by 45 equals 50. 



Boilers having flues larger or smaller 

 than three inches in diameter will also 

 have a horsepower larger or smaller 

 than the number of tubes, calculated on 

 the basis of a length of fifteen feet. 



For boilers of medium size it is cus- 

 tomary to allow one square foot of grate 

 for three horsepower. In larger boilers 

 the grates may be relatively smaller. 

 On the other hand, if the needed capac- 

 ity is much less than fifty horsepower, 

 it will be advisable to have the grates 

 relatively larger. 



For each horsepower there should be 

 from twelve to fifteen square feet of 

 heating surf&ce in the boiler, and under 

 favorable conditions it will provide 

 steam for 100 square feet of radiating 

 surface. 



The area of the boiler flues should be 

 from one-ninth to one-sixth the area 

 of the grate, and the chimney flues 

 should be one-seventh to one-tenth of 

 the grate area. In setting a boiler, al- 

 low about nine square inches under the 

 boiler and over the bridge for each 

 horsepower. 



As already stated, these estimates are 

 for boilers of medium size and should be 

 slightly modified for those of larger or 

 smaller sizes.

The Market. 



The supply of stock is larger this 

 week than last, but the demand cleans 

 up everything daily. Prices hold up 

 well, also. The weather has been 

 springlike and all stock as a result is 

 coming on in the best condition. 



Various Notes. 



Business has increased to such an ex- 

 tent with the Arapahoe Flower Store 

 that Frank Frazer, proprietor, has 

 found it necessary to move into larger 

 quarters at 1527 Arapahoe street. 



Boldt & Lundy and the Central Flo- 

 ral Co. both are using electric signs 

 bearing the slogan, "Say It with Flow- 

 ers. ' ' 



The sympathy of the trade is ex- 

 tended to Miss Lena Webb, whose 

 mother died January 30, at the age of 

 73 years. Funeral services were held 

 at the home February 3 and burial was 

 at Riverside cemetery. 



R. Schilling is now with C. F. Maler. 



The American Flower Shop showed 

 extra fine Ophelia Supreme in its win- 

 dow last week. Mr. Claussen, of this 

 firm, reports business as excellent.
