The Weekly Florists' Review. 



Fbbruary is, 1912. 



low the ridge, and six 1 14 -inch pipes in 

 the coils, or eight 1-inch pipes could be 

 used if preferred. For returning the 

 water to the boiler a 1^-inch pipe will 

 be amply large and a 1-inch pipe might 

 be used. 



The returns in a gravity system 

 should be two feet or more above the 

 level of the water in the boiler, and if 

 they are below the level of the water it 

 is not strange that trouble is expe- 

 rienced, as water always seeks its level. 

 Unless it will be possible either to lower 

 the boiler or raise the coils, some me- 

 chanical means of returning the water 

 will be required. For a house of this 

 size it will probably be better to lower 

 the boiler, if drainage can be secured 

 for the boiler pit. If this cannot be 

 done, it will be better to use an electric 

 pump rather than carry pressure enough 

 to operate a steam pump or trap. In 

 most cases where there is less than 

 1,000 square feet of glass, hot water is 

 preferred to steam for heating green- 

 houses. 



A LOW HOUSE FOR LETTUCE. 



I intend to build a greenhouse next 

 month, 12x100 feet. The side walls 

 will be only one foot high, which will 

 make the house three and one-half feet 

 high at the gables. There will be two 

 5-foot ground beds, one on each side, 

 with a 2-foot walk in the center, which 

 I shall dig two feet deep, to provide 

 head room. How should the house be 

 built, running east and west or north 

 and south? I shall use cypress sash- 

 bars, I%x2i^in.x7ft., and 14x14 

 double-strength glass. How many ven- 

 tilators should be used in this house, 

 with three 14 x 14 panes in them? There 

 will be a door in each end, which can 

 be opened in especially hot weather. 

 Please give piping directions, also, for 

 both steam and hot water. I shall use 

 this house for lettucf during the winter 

 and for vegetable plants in the spring. 

 Would a 10-foot house be better? My 

 location is eastern Ohio. P. H. G. 



If a narrow house is to be built, a 

 width of ten feet will be more econom- 

 ical of space, as to occupy a width of 

 twelve feet either the beds or walk will 

 have to be rather wide. It is generally 

 regarded as a mistake to build a house 

 as low as the one described. Instead 

 •of building the house 12 x 100 feet, it 

 will be found better in every way to 

 lave it 20 x 50 feet, with the walls 

 four feet high; or, better yet, have 

 the walls five feet high, with two feet 

 of glass at the top. 



For the house 12 x 100 feet,' about 

 nine ventilating sashes of the size men- 

 tioned should be used. The house can 

 be run in the direction that will best 

 suit the other conditions, although a 

 north and south house would be pref- 

 -erable in some ways. To heat such a 

 house with hot water, run a 2i^-inch 

 _pipe under the ridge and two 2-inch 

 returns on each wall, near the plate. 

 For heating it with steam, use a 2-inch 

 overhead main and two l^^-inch re- 

 turns upon each of the plates. If the 

 house is much exposed, an additional 

 return will be required if the house is 

 to be heated to 50 degrees with hot 

 water,

 Society, at Brookings.

and less water space than 

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



"'Superior Standard" Greenhouse Boflers 



find them perfectly satisfactory. We frequently receive re-ordera 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
