PoEHT.MANN Beos. Co., Morton Grove, 

 III., this season burned approximately 

 15,000 tons of coal, costing in the neigh- 

 borhood of $50,000. 



The Martin Grate Co., 283 Dearborn 

 street, Chicago, has issued a humorous 

 booklet, paraphrasing the old nursery 

 rhyme, "The House that Jack Built," 

 in the interest of its rocking grate, now 

 used in many greenhouse establishments. 



HEATING HINTS. 



Do not screw a valve open or closed as 

 hard as you can. It injures the threads 

 and in a short while you can not shut it 

 tight when you need to. 



Keep all your piping tools clean and 

 well oiled. Put them in a box or bn the 

 wall, where anyone can lay his hand on 

 them in a hurry. 



Give the night fireman an 18-inch Stil- 

 son and a 12-inch monkey wrench of his 

 own. Do not let anyone but him use 

 them. He will know just where they are 

 then, when a need arises in the middle of 

 the night. 



Keep the valve stuffing boxes well 

 packed. It keeps the steam and water 

 in the system and not out in the air. 



Pipe that is 1^4 -inch is the best size 

 to use in a steam system. Use 2-inch 

 pipe for hot water. 



In- a steam system, to figure the run- 

 ning feet of 1^-inch pipe a main will 

 carry, square the inside diameter and 

 multiply it by four and by 100. Exam- 

 ple: A 5-inch main will carry 5X5X4X 

 100, or 10,000 running feet. To find the 

 size of a main when you know the run- 

 ning feet, divide the running feet by 100 

 and by four and the square root will be 

 the diameter of the main required. Ex- 

 ample: 10,000 running feet of 1^4 -inch 

 pipe, to find size of main required ; 

 10,000-MOO=1004-4=25, of which the 

 square root is 5, the size of the flow.

HOUSE IN COLD CLIMATE. 



We are putting up a house 22x120, 

 facing south, and have a boiler-room on 

 the east end as a continuation of the 

 house as far as the roof is concerned. 

 The coal shed is north of the boiler-room, 

 with a three-foot gangway between with 

 the exception of a passageway three feet 

 above ground. The height at the ridge is 

 twelve feet six inches. The eaves are five 

 feet six inches and there are thirty-two 

 inches of glass on each side below the 

 ■eave; all glass on the west end. The

 house mainly for carnations; our idea is 

 to use hot water. We use a lignite coal
