Farm And Garden

Acontributor to American Gardening was asked how to build a small hothousa for raising tomato plante, a house to bo heated by a flue. Here is his reply : In order to prow from 10,000 to 15,000 tomato planta for ppring planting it will roqnire, where thcy aro 3 inohea apart, a house 10 by 150 feet. If grown in 3 inch pots, allowing room for tbe plants to spread, the house will have to bo 19 by 300 feot, or two houses 19 by 150 feet. The forrner house woultl have two beds 3 feet 6 juches wide running the entiro length, allowing 2 feet for the walk. The 19 foot houses can be j vided as follows : The two ontside beds, eacb 3 feet (i incheswirio and the center beds each 4 feet wide. This leaves 6 (eet for the throe walks, which can be ! llivided to suit the grower Herewith is shown a section of a greenhouse 10 feet wide, 4 feet high on the sides, 2 feet 6 inohes of which is of wood, and the balance is glass up to the píate, vvbich is of wood. It is better to have the upper part of the sides of glass, because the plauts will do better than where theyAre of wood. The height to the ridge is v feet. There is no need for heavy rafters, but the roof can bo made of strong sash bars and joined together at the ridge by pieces of wood made to fit the angle of the roof, aud to be securely screwed to the rafters or sash bars to prevent any sag to the roof, or cast iron angle brackets mado for the purpose eau be purohased. It. is uot necessary to put them on every sash bar if there are no rafters, but put the pieces about 6 feet apart. The ventilating sash are fastened to the ridge, aud are best operated by means of the orciinary ventilating machinery, which eau be bought for a small iigure. If preferred, ventilation can be snpplied to both sides of the ridge. Regarcling the flues, it is customary to build a furuaco at each end of the house, ono under each bed, and to make the flues of cement tilo, carrying them to tho farther euds of the house, wliere they are connecteil to chimneys rising abovo the top of the greenhouse. Care must be taken to have all the joints tight, as the gas frorn thern is bad for the plants. It is better to pay a little more and put in either a hot water or steaiu heating apparatus, which can be relied upon. The temperature required for coldest nights is from 45 to 50 dogrees.
