visable to use three 2%-inch flow pipes 

 and seven 2-inch returns, placing two 

 returns on each side wall and the re- 

 maining ones under the middle bench. 



For a temperature of 60 degrees, put 

 in two additional returns. If possible, 

 the lower end of the returns should be 

 three or four feet or more above the 

 top of the boiler. The boiler should 

 have a grate the area of which should 

 be at least thirty inches square. 



DAMPER ON CHIMNEY. 



I have a Wilks hot water boiler at 

 present and am thinking of getting an- 

 other as soon as I increase my glass 

 area. I think, however, that too much 

 of the heat goes up the chimney and 

 have tried to devise some method of 

 diverting the draft downward. It is 

 my opinion that, by bricking in the area 

 between the two boilers, I could bring 

 the extra heat into contact with the 

 back of the boilers and still permit the 

 smoke to escape from below, as in an 

 ordinary range. I shall appreciate any 

 information you can give me concern- 

 ing the solution of this problem.

If the draft of the chimney is suffi- 

 cient, it will be advisable to put in a 

 damper and, by securing an indirect cir- 

 cuit for the escaping smoke and gases, 

 utilize a considerable amount of heat 

 whicli would otherwise be lost. 



If anything of the kind is arranged, 

 have the connection with the smoke flue 

 made in sucli a way that a direct draft 

 can be obtained when starting the fire 

 in the boiler. The arrangement proposed 

 would probably work better with a good 

 grade of hard coal or coke than witli 

 soft coal.

Record s are as important in the growing business as 

 in any other business. Progressive growers who 

 spare no effort in raising highest grade stock use 

 Standard Recording Thermometers and know the 

 great aid of keeping records of temperatures. Your 

 equipment is far from complete if you have no 

 Standard Recording Thermometer. 



The actuating element of the Standard Recording 

 Thermometer is of lamina metal, which, besides 

 being extremely sensitive to temperature changes, 

 is practically indestructible. Record charts are 

 furnished either daily or weekly, and the whole 

 mechanism is contained in an attractive 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 high- 

 est possible standard of manufacture.
