house with one walk, or a 20-foot house 

 with two walks are the most convenient 

 dimensions for violet houses. 



In your case, if you use hot water, as 

 I infer you do from the heater named, 

 you will need a 2-inch flow pipe under 

 the ridge, returning just under the gutter 

 on the side walls by four l^^-inch pipes 

 on each side. The flow pipe should have 

 an upward slope from the boiler to the 

 far end of the house, say of six inches 

 in the length of the house, and the re- 

 turns an equal drop. The top of the 

 boiler should be two feet or more below 

 the lowest pipe in the house system. The 

 expansion tank should be connected to 

 the main return near the boiler and be 

 elevated so as to be at least six feet 

 above the highest point in the heating 

 system. L. C. C. 



BOILER AND PIPING. 



I have two houses 20x100, with walls 

 four feet high, and two houses 27x100, 

 with walls six feet hi^. My boiler is 

 3x12 feet, with thirty 3-inch flues. Is 

 it large enough? There are two 2-inch 

 overhead Wows in each house and 1,200 

 feet of li4-'nch pipe in each. Is it 

 sufficient radiation in Missouri climate? 



B. L. I. 



The piping is satisfactory for steam, 

 particularly for the houses 20x100 feet, 

 a little scant for roses in the houses 

 twenty-seven feet wide, but all right for 

 carnations and other cool stock. The 

 boiler in question is just about half large 

 enough to care for the plant in question. 

 You have in the four houses, as piped, 

 about 5,200 square feet of radiation, and 

 the boiler has about 375 square feet of 

 heating surface, which gives it a capa- " 

 city to carry about 3,000 square feet of

radiation, or 2,200 feet less than you 

 actually have. It would be wise to in- 

 stall two boilers of the size specified. 

 That would give you a factor hf safety 

 of about 800 square feet of radiation, or 

 enough to carry another cool house 20x 

 100. L. C. C. 



TIME AND HEAT UNITS. 



If ashes are put on the center of a 

 burning mass of wood in the firepot to 

 make it burn slower and longer, will we 

 get the same amount of heat out of those 

 pieces of wood as if we allowed them to 

 bum up freely and shut off the draft? 



J. F. D. 



Provided that combustion is complete, 

 i. e., the wood or fuel is completely 

 burned, it will make no difference in the 

 total amount of heat thrown off whether 

 the burning takes place in one hour or 

 four hours. The amount of heat given 

 off in any given time will depend upon 

 the rate at which the burning takes place, 

 but the total amount will be the same 

 whether the given quantity of fuel is 

 burned quickly or slowly. Different fuel 

 substances give off different quantities 

 of heat for a unit volume, or weight of 

 the material, but time is not a factor. 

 In fact, there is just as much heat liber- 

 ated when a cord of wood rots as when 

 it burns. In one case the process is 

 rapid and the heat is perceptible, while 

 in the other it is so slow that the heat 

 is imperceptible. L. C. C.

PROPAGATING HOUSES. 



I am putting up two propagating 

 houses, each 10x100 feet, side walls four 

 feet, ridge seven feet. I am planning 

 to heat with hot water. Can I trouble 

 you to advise the best arrangement of 

 piping for Minnesota climate? 



F. F. L. 



For propagating houses the plan of 

 piping I should follow would be to run 

 a 2% -inch riser under the ridge to the 

 far end of the house. There take off two 

 branches and return under each side 

 bench with four 2-inch pipes, eight 2-inch 

 pipes for the whole house. I should then 

 box in the bench so as to confine all the 

 heat possible underneath it, arranging the 

 bench so as to leave about 1-inch space 

 between the back of the bench and the 

 wall of the house to allow the passage 

 of heat and to keep the bench away from 

 the cold side wall of the house. Hinge 

 one run of boards so the heat can be 

 liberated if desired. L. C. C.
