EXPANSION JOINTS. 



What success is being had with ex- 

 pansion joints in steam coils? Where 

 should they be placed? Where can we 

 procure them and at what cost? Please 

 tell us of the experience some greenhouse 

 owners have had with them. 



X. Y. Z. 



The expansion of the heating pipes 

 used in all ordinary greenhouse struc- 

 tures can be compensated for by a sim- 

 ple arrangement consisting of a swing 

 joint constructed with two ells and a 

 close nipple joining the heating pipe at 

 right angles with another pipe twelve 

 to eighteen inches in height, according 

 to the space at command. For long, 

 straight runs of large pipe where no 

 turns can be thrown in, an expansion 

 joint is sometimes essential, but in ordi- 

 nary work such joints can be avoided. 

 If needed, expansion joints may be pur- 

 chased of those who advertise heating 

 specialties in the Review. L. €. C. 



STEAM BOILER FOR HOT VATER. 



I have two greenhouses, running east 

 and west, each 20x100 feet, five feet 

 high on the side walls and twelve feet 

 to the ridge; no glass on the sides. The 

 floor has a fall of two feet in 100 feet, 

 to the east. I have a twelve horse-power, 

 submerged-flue steam boiler. Can it be 

 80 installed as to use it for a hot water 

 plant instead of for steam! I can sink 

 the boiler in a pit at the lower end of 

 the house. I have natural gas for fuel. 

 I also have good city water pressure. 



J. H. H. 



You can easily arrange the steam 

 boiler for hot water heating. I doubt, 

 however, if the boiler in question will 

 have capacity to maintain a satisfactory 

 temperature in both houses during se- 

 vere weather. It is about 300 square 

 feat short of the actual capacity needed 

 for the houses. It is usual to add a lib- 

 eral factor of safety to the size of the 

 boiler, after figuring the actual require- 

 ments of the houses. If hot water under 

 pressure is used, eaieh house should have 

 a 3-inch riser and twelve 2-inch returns, 

 arranged under the benches or upon the 

 side walls, according to the use to which 

 the house is devoted. The expansion

tank should be placed well up, unless city 

 pressure is used, in which case the ex- 

 pansion tank can be dispensed with, pro- 

 vided the pressure is not too great.

PITCH OF HOT VATER PIPES. 



Will you please tell me what is the 

 least possible pitch I can give hot water 

 pipes in 140 feet? I cannot see my way 

 out in giving the returns under the 

 benches any more than ten inches and 

 the main return in the walk to the boiler 

 ten inches. All flows are overhead. 



P. J. S. 



Under a pressure system with over- 

 head flows you should have no difficulty in 

 securing a good circulation with ten 

 inches of fall in 140 feet, provided the 

 pipes are carefully graded and are 

 straight. One hundred forty feet is a 

 pretty good distance to carry hot water 

 upon a graded system, and all close 

 turns and small pipes should be elim- 

 inated if you are to make it successful. 

 Do not attempt to install anything less 

 than 2-inch pipe on runs of this length.

TARRYTOVN,N.Y. 



The annual June show of the Tarry- 

 town Horticultural Society was held in 

 Music Hall June 18. Boses and straw- 

 berries, which are generally the leading 

 feature at this exhibition, were scarce. 

 Cut flowers, farm shrubs, and perennials 

 were numerous and of excellent quality, 

 while the exhibits of vegetables sur-

passed those of any previous June ex- 

 hibition. A fine exhibit of plants and 

 cut flowers from the F. R. Pierson Co. 

 made a good display. Notable among 

 the cut flowers was an excgllent collec- 

 tion of peonies. The judge awarded this 

 exhibit a certificate of merit. Scott Bros, 

 showed quite an assortment of hybrid 

 rhododendrons in pots. Geo. Middleton 

 was awarded the prize for strawberries, 

 Howard Nichols for twelve varieties of 

 vegetables, John Elliot for six varieties 

 of vegetables, Geo. Witlinger for sweet 

 peas, W. H. Waite for shrubs, and Wm. 

 Grierson for perennials. Special prizes 

 were awarded Geo. Middleton for green- 

 house grapes, peaches, figs, and melons, 

 to Geo. Witlinger for grapes, Robt. An- 

 gus for grapes and tables of decorative 

 plants, D. McFarlane for greenhouse 

 melons and vegetables, J, W. Smith for 

 perennials, John Woodcock for roses, W.

 for perennials.

 roses, the judge did not award the J. H.
