every ten or twelve feet. A narrow board is nailed 

 inside, on each side of the plate, for the lower end 

 of the sash to rest on. The sashes are 3x6 and 

 made of glass 8 x 10, on account of giving more light. 

 Every alternate sash is permanently fastened by three 

 large screws on either end. The others can be raised 

 up on top to admit air, when necessary. This is con- 

 veniently done by having a piece of flat iron fastened 

 to the sash, and thi-ee or four holes in the iron. The 

 sash is raised to the height required, by this piece of 

 iron and secured by a pin driven in the ridge-pole, 

 which holds the iron in place. 



On the inside of the lower end of the frame of 

 each of the movable sashes, is screwed a piece of inch 

 stuff, three and a half feet long. Two inches of this 

 narrow strip of wood, on either side, will project 

 under the permanent sashes and thus prevent the 

 movable ones from being lifted off by a gale of wind. 

 All through the Winter, and more especially towards 

 Spring, a considerable amount of water is needed to 

 keep the plants in good condition. This water is 

 saved from the gutters of the houses, led by pipes 

 into a cistern, which runs across the houses. A neigh- 

 bor who has three houses, one hundred and twenty 

 feet long, each, has a cistern, twenty-seven feet long, 

 eight feet deep and seven feet wide, which holds a 

 sufficient supply of water. Another grower, who 

 has five connected houses, each two hundred feet 

 long, has a different arrangement. At about one 

 hundred feet from either end of these houses, the 

 pitch of the roof is changed, running across from 

 east to west, the main houses run from north to
