pipe, although a 9-inch pipe would 

 answer. For this the chimney should 

 be twelve inches in diameter, inside 

 measurement, and twenty-eight inches, 

 outside measurement. The height of 

 the chimney will depend somewhat upon 

 the surroundings, but it should be at 

 least thirty feet in height, and even 

 more if there are taller buildings or 

 trees that will prevent a good draft. 



The comparative value of concrete 

 blocks and bricks for the stack will 

 depend upon how well they are made. 

 We should have little choice if both 

 are of good materials and proper atten- 

 tion has been given to their manufac- 

 ture. As a rule, the blocks are more 

 likelv to be defective. 



MORE PARTICULARS NEEDED. 



I liad a hot water heating plant in- 

 stalled at my greenhouse last fall. The 

 house is 16x50, with an office 12x12 at 

 the east end. The piping comprises 

 550 feet of radiation and is connected 

 with a 900-foot l)oiler, the top of which 

 is three feet below the coils. The flow 

 pipe is fifty-five feet long and its highest 

 point is at the farther end from the 

 boiler. All other pipes drop toward the 

 boiler, with a slope of an inch and a 

 half in ten feet. I do not think the 

 system is working properly, because 

 when the water reaches a temperature 

 of 150 degrees the boiler commences to 

 sing, and when it reaches 180 degrees a 

 boiling noise is lioard. The lower end 

 of one of the coils docs not get warm 

 till tlie water roaches ISO degrees. Please 

 let me know how I can remedy this 

 trouble. A. J. B.— Wis. 



The description of the heating system 

 does not contain all the particulars that 

 are necessary to enable us to determine 

 the cause of the trouble. There is ample 

 radiation for a temperature of 65 de- 

 grees and the boiler is large enough for 

 a house 100 feet long, unless there is 

 more than the usual amount of glass in 

 the walls. The only change we are able

means better flow- 

 ers—more naturally 

 Brown. The More- 

 head System main- 

 tains an even, con- 

 sistent temperature 

 throughout your grow- 

 ing houses by elimi- 

 nating sluggish circu- 

 lation and delivering 

 every drop of the 

 condensation, which 

 is now allowed to clog 

 up your steam lines, 

 directly back to the 

 boiler wbile it is hot. 



You not only get 

 better flowers, but you 

 also save a large per 

 cent of your fuel.

 SYSTEM 



Big representative concerns like the Minneapolis 

 Floral Company, the Memphis Floral Company, the 

 Pittsburgh Floral* Company, etc., etc., now drain 

 their steam lines and return the pure hot conden- 

 sation immediately to the boilers as feed water 

 with the Morehead System. 



Quickly and easily attached to your present appar- 

 atus, the Morehead System gives you absolute con- 

 trol of the temperature in every foot of your houses 

 —and soon pays for itself in the saving of fuel. 

 Tell us about your present heating troubles— our 

 engineers will give you expert information on ex- 

 actly what you may expect the Morehead System 

 to do for you— and send you a book which covers 

 the greenhouse steam plant situation thoroughly.
