Great Grates* 



As fast as old grate bars are burned 



out many growers are putting in the 



Martin rocking grate. The call for this 



grate is largely increased by the fact 



that the growers who have used it for 



one or more seasons are almost without 



.v. exception equipping other boilers with 'it. 



,'.; • The grate costs considerably more than 



.; ~ the stationary bars, but is figured to 



make a decided saving in fuel, and that 



is what all the growers are after.

heater; the grate surface is 24x36 inches. 

 Temperature often goes 20 to 25 degrees 

 below zero. G. F. P. 



I do not think it will be practicable 

 to make a complete board partition be- 

 tween the two layers of grout in the 

 wall. Vacant spaces, however, are de- 

 sirable, and can be provided for by 

 using upright forms in the center of the 

 wall, which can be covered with paper 

 when the form is set, and as the con- 

 crete hardens the form is withdrawn, 

 leaving a hollow space in the wall. 

 These air chambers will be better non- 

 conductors than the board partition. The 

 boards can be used if at intervals a 

 board is left out so as to allow a space 

 for bonding the wall. A 12-inch bond- 

 ing strip every three or four feet will 

 be suflBcient. The house 20x80 feet 

 can be piped for carnations by using 

 ten runs of 2-inch pipe, providing the 

 side walls are not more than four feet 

 six inches high. Two coils of five pipes 

 each, in which one pipe is a flow, should 

 be sufficient to heat the house. This 

 arrangement provides for two 2-inch 

 flows and eight 2-ineh returns, four re- 

 turn pipes in each of two coils, or 

 otherwise distributed under the benches.

TWO LONG HOUSES. 



I have two houses running east and 

 west, with the boiler pit at the east end, 

 six feet below the greenhouse floor. One 

 of the houses is 10x102 feet, 4-foot wall, 

 8-foot ridge. The other house is 

 16x102, 4-foot wall, 9-foot ridge. I 

 want to heat them by hot water, 

 running both flow and return un- 

 der the benches. The land slopes four 

 feet in 100 feet, to the east. I have a 

 boiler rated at 2.000 square feet radi-

The 10-foot house can be heated by six 

 2-inch pipes. These can probably be best 

 arranged as two coils, each consisting of 

 a flow and two returns, arranged either 

 under the benches or along the side 

 walls. The 16-foot house requires nine 

 lines of pipe, which can also be arranged 

 in two coils if so desired. A manifold 

 of five pipes on the most exposed side

and one of four pipes on the most shel- 

 tered side, one of the pipes in each group 

 serving as a flow pipe, is the best plan.

VENTS AND STEAM TRAP. 



Our present range is 77x112 feet. We 

 have our boiler above grade, and use a 

 Hippard standard steam trap. The 

 boiler is at the northeast corner. We 

 wish to build an addition on the west, 

 and a larger one on the south, both of 

 them farther from the boiler than the 

 present range. In each house, our plan
