And Its 



Flues 



The side flue openings to the cross 

 fire channels prevent the rueh of the 

 burning gasee to rear of boiler. They 

 make an equal distribution of the 

 burning gases in every part of the 

 fire-box chamber. They make every 

 section equally efficient — the front 

 ones the same as the rear. Then be- 

 fore the hot gases can reach the 

 smoke outlet they must first travel 

 three times the boiler's length, giv- 

 ing you a cool chimney and hot 

 coils. Buy a Burnham.

I am planning to build a water system 

 consisting of a round cement tank, forty 

 feet in diameter, the sides to be ten feet 

 high, the bottom being cone-shaped, mak- 

 ing the center . at the bottom five feet 

 lower than the sides. The tank to be 

 situated on an elevation twelve feet 

 higher than the benches in the green- 

 houses and 700 feet from same. The 

 reservoir* to be tapped from the bottom 

 of the cone. How many pounds pressure 

 will a 2-inch pipe running from the tank 

 to. greenhouses give, and how many lines 

 of %-inch hose can be used at one time 

 from the main pipe? I have a pond 

 twenty-five feet lower than the bottom 

 of the proposed tank and situated about 

 half way between the tank and green- 

 houses. "Will a large windmill near the 

 pond be sufficient power to pump water 

 supply, with use of a check valve, direct 

 into the 2-inch main connecting the 

 reservoir and greenhouses? C. D. L.

 have no influence on the pressure in the

main. The pressure in the main is en- 

 tirely due to the height of the water 

 level in the tank. The pressure at the 

 nozzle is due to the difference in the 

 height of the water level in the tank 

 and the height of the opening from 

 which the water is drawn. In your case, 

 with the water seventeen feet above the 

 level of the opening in the greenhouse, 

 you should have about eight pounds less 

 the friction in the pipes, which is greater 

 the smaller the pipe used. 



In this case I would urge the use of 

 a large main, say 4-inch, in case much 

 water is" required. Also use large dis- 

 tributing pipes. Carry 1 14 -inch pipes to
