3-inch \]j)right. At each end of the 

 house divide the 2-inch pipe into three 

 2-inch pipes, one to follow the slope of 

 the roof to the south bench and there 

 divide to supply thr6e 2-inch pipes 

 placed under this bench, which shall ex- 

 tend to the center of the house and 

 there, by a header, be collected into one. 

 The wide benches should each have a 

 2-inch supply pipe dividing to supply 

 three 2-inch returns under each. These 

 should then be united by a header and 

 all finally collected into a 2%-inch re- 

 turn pipe which should return to the 

 toiler. 



The west end of the middle house can 

 "be piped by hanging four 2-inch pipes 

 on the north wall and three on the 

 south wall, and feeding all from a 

 2-inch flow pipe under the ridge. The 

 east end should have a 2-inch riser un- 

 der the ridge, two 2-inch returns under 

 each side bench and four 2-inch returns 

 under the wide bench. On account of 

 the cross walk through the middle of 

 this section these pipes will have to be 

 carried close to the ground. A 2%-inch 

 riser should be brought from the boiler 

 to a point under the ridge and there 

 carried in an upright to supply the 

 two 2-inch lines going to either end of 

 the house. 



The north house, the one twenty-two 

 feet wide, is a little more difficult to 



With such a plant to be run with hot 

 water and soft coal fuel I should ad- 

 vise the use of a steel boiler with jack- 

 eted fire box, i. e., inside the shell with 

 water all around and with large return 

 tubes. There are many boilers of this 

 pattern on the market. L. C. C. 



STEAM DOME UNNECESSARY. 



A boiler is better without the steam 

 dome, says the Practical Engineer. The 

 steam dome is supposed to effect a dry- 

 ing of the steam and also add to the 

 steam space of the boiler. Both of these 

 purposes it certainly performs, so that 

 it cannot be objected to upon the 

 grounds of inefficient service. In the first 

 place, it removes the outlet of the steam 

 to a greater distance from the water 

 surface and consequently there is less 

 chance of carrying water over when the 

 boiler primes slightly. Being of com- 

 paratively large cross-section, the velo- 

 city of the steam passing through it on 

 the way to the outlet is comparatively 

 slow. This gives the moisture particles 

 entrained with the steam an opportunity 

 to fall out of the steam by mere action 

 of gravity. However, there are other 

 and better ways of securing the same 

 result. The dry pipe is just as useful 

 in obtaining dry steam as is the dome. 

 It is merely a perforated pipe attached 



Vegetable Forcing, 



LETTUCE AND RADISH. 



At what time should Grand Eapids let- 

 tuce be sown to get a crop by November 

 20? What is the best method of culture? 



What is a good forcing radish? 



J. H. T. 



Grand Eapids lettuce takes from ten 

 to twelve weeks from time of sowing 

 the seed until they are large enough to 

 be most profitable to cut, so if you want 

 them at November 20, the sooner you get 

 the seed in the better. For cultural hints 

 see the answer to E. C. L. in the issue of 

 the Beview of August 25. In addition 

 to this I would advise to sow the seed 

 rather thinly in flats or cold frame and 

 prick over once before the final planting, 

 setting them about two inches apart each 

 way. Before the plants begin to crowd 

 one another plant out where they are to 

 mature, allowing a space of eight inches 

 each way. 



The best forcing radish we have tried 

 is Non Plus Ultra. This is a dwarf, 

 quick maturing variety and one that has 

 always succeeded well with us.

pipe by this plan, but it may be done 

 as follows: Bring a 3-inch riser to a 

 point under the ridge and carry a 2-inch 

 one to the west and a 2i.^-inch line to 

 the east as far as the partition of the 

 room 22x24 feet. At this point insert 

 a tee with a 2-inch opening looking into 

 the room 22x24 feet and another look- 

 ing down on the west side of the parti- 

 tion. From each carry a 2-inch line, 

 the one in the east section to return by 

 two pipes under the north bench, three 

 under wide bench farthest north, two 

 under the other wide bench and one 

 under the south narrow bench. The 

 other section can be piped by carrying 

 returns from each end of the compart- 

 ment to the fifty-foot line, using the 

 same number and disposition of pipes as 

 in the house 22x24 feet. If you do not 

 wish to use valves in the flow pipe so as 

 to cut off the house 22x24 feet, both the 

 riser and returns can be carried through 

 without interruption and the size of the 

 riser from the fifty-foot line east need 

 not be increased; a 2-inch line in each 

 direction will be sufficient. 



The little house between the office 

 and boiler house requires 184 feet of 

 2_ineh pipe. It should have four lines 

 of 2-inch pipe under the north bench 

 and four lines under the wide bench. A 

 -inch line under the ridge will supply 

 DOth coils. 



to the outlet, but lying wholly within the 

 boiler. The areas of the perforations 

 when taken together . are considerably 

 greater than that of the steam main lead- 

 ing from the boiler. The dry pipe is 

 usually placed so as to extend along the 

 upper part of the steam space and paral- 

 lel to the longitudinal axis of the boiler 

 shelj. It thus draws steam from a 

 large portion of the steam space. 



Its main advantage over the dome, 

 however, lies in the fact that its attach- 

 ment to the bailer does not weaken the 

 shell to any appreciable extent. In order 

 to attach a dome, the shell of the boiler 

 beneath the dome is cut away, thus re- 

 moving a large amount of solid plate, 

 making the boiler considerably weaker 

 under the transverse strains. 



I HAVE been pleased with the Eeview 

 during the past year and could not well

Columbia, S. C. — Martin Stork, of the 

 Eose Hill Greenhouses, says the florists' 

 business in this state is still in its in- 

 fancy, but judging from the increasing 

 demands for cut flowers from all sec- 

 tions of the state, it is plain that it is 

 no longer an experiment. Greenhouses 

 are being built and enlarged in a num- 

 ber of the smaller towns. 



HOUSES FOR CUCUMBERS. 



Different types of houses are utilized 

 in the growing of cucumbers. Market 

 gardeners who raise two or three crops 

 of lettuce during the fall and winter 

 generally plant cucumbers in their let- 

 tuce houses in late winter or early spring. 

 These lettuce houses are almost invariably 

 either two-thirds or even-span, and in 

 Massachusetts they are provided with 

 ground beds instead of benches. They 

 are glazed with 16x24 or 16x28-inch 

 glass, and in some of the modern houses 

 20x30-inch glass is used. The use of this 

 larger glass results in giving a house 

 considerably more light, thus increasing 

 growth, A house glazed with 20x30-inch 

 glass requires only five sash bars to 

 cover a space demanding six sash bars 

 where 16x24 or 16x28-inch glass is used, 

 and the inferior light conditions due to 

 more frequent lapping are avoided. 



A modern even-span lettuce house 

 40x630 feet, constructed with 20x30-inch 

 glass is known to have cost $952 per lin- 

 eal foot or 23 cents per square foot of 

 ground covered. According to our esti- 

 mate a house of this size, if constructed 

 with sash bars two inches wide, would 

 by the use of 16-ineh glass furnish about 

 745 square feet more opaque surface, 

 than if glazed with 20-inch glass; or in 

 other words there would be about nine- 

 teen per cent. less sash bar surface to
