necessary to run a i^. inch pijie from 

 the end of each of the other flow pipes 

 to a point level with the top of the ex- 

 pansion tank. There will then be no 

 chance for the air to gather in the pipes, 

 unless the end of one of the air relief 

 pipes becomes closed. 



HEATING RANGE AND DWELLING. 



Will you kindly tell me how to pipe 

 two houses, one 11x26 feet and the other 

 18x50 feet, where the small house has 

 two feet of board and three feet of 

 glass in the side walls, and the large 

 house has three feet of board and three 

 feet of glass in the side walls-? I wish 

 to maintain 55 or 60 degrees when the 

 outside temperature goes down to 10 

 below zero, and also wish to heat my 

 dwelling, 20x30 feet with an 8-foot ceii- 

 ing, with the same plant. I should like 

 to use steam, but do you think an up- 

 right high-pressure boiler will work all 

 right when carrying about twenty 

 pounds of steam? I shall use benches, 

 three feet to top of soil, in both houses. 

 Will a heating plant that will maintain 

 60 degrees at 10 degrees below zero hold 

 50 degrees at 20 below? 



A. R. C— Kan. 



For a plant of the size described it 

 would be more advisable to keep the 

 steam pressure down to five, or at most, 

 ten pounds, as it would hardly be feas- 

 ible to have a regular night fireman. 

 With the pressure named in the above 

 letter, it would be possible to make a 

 slight reduction in the amount of radia- 

 tion which will be suggested, but 

 would consider the element of safety of 

 greater account. 



An upright boiler would be found 

 satisfactory, provided the floor of the 

 boiler pit is low enough so that the 

 water line in the boiler will be three or 

 four feet below the lower end of the 

 coils; if this cannot be secured, it will 

 be necessary to use a pump or steam trap 

 to liandle the return water. 



For low-pressure steam, use a 2-inch 

 flow pipe and six or seven IVi-inch re- 

 turns in the smaller liouse, while the 

 large one will require a 2M!-incli main 

 and nine or ten li/i-inch returns. 



Carry the flow pipes with a slight 

 fall one or two feet below the ridge, and 

 place the returns under the benches. 



A round boiler should have a grate of 

 about thirty-one inches in diameter to 

 heat the dwelling and the two green- 

 houses, if soft coal is to be used as fuel. 

 This should hold tlie temperature above 

 50 degrees wlien it is 20 degrees below 

 zero outside, if proper attention is paid 

 to the firing.

Records are as Important In the growlngr busi- 

 ness as In any other business. Progressive grow- 

 ers who spare no effort in raising highest grade 

 stock use Standard Recording Thermometers and 

 know the great aid of keeping records of tem- 

 peratures. Your equipment is far from complete 

 if you have no Standard Recording Thermometer. 



The actuating element of the Standard Record- 

 ing Thermometer Is of lamina metal, which, be- 

 sides being extremely sensitive to temperature 

 changes, ia practically indestructible. Record 

 charts are furnished either daily or weekly, and 

 the whole mechanism is contained in an attract- 

 ive metal case fitted with lock and key, which 

 insures the record from being tampered with. 



The clock movement is of extremely high grade; 

 everything about the instrument is up to the 

 highest possible standard of manufacture.
