Account of Mr. S. Siveetser''s Green-house. 5 



plate is made of timber, eight inches by four, and has a gut- 

 ter, to take off the water from the roof, grooved in it. 



The dimensions of the roof sashes are as follow^ : — lower 

 ones, nine feet by three and a half ; upper ones, six by three 

 and a half; front, two and a half by three and a half. The 

 glass made use of is seven inches by five ; five rows of lights 

 in each sash. The laps are about an eighth of an inch ; but 

 this may be varied at the option of the builder, either more or 

 less ; they should be well fitted, and the work done thorough- 

 ly by a first rate glazier, or much cold will blow in through 

 our long winter nights, and cause the consumption of much 

 more fuel. Care should also be taken that the crowning part of 

 the glass is put downwards, that the water may be carried 

 off" in the centre of the lights, and not be allowed to get un- 

 der the putty.'/ The door which opens into the green-house 

 is two feet seven inches wide and six feet high. The walk 

 is two feet six inches wide ; twelve inches in the centre be- 

 ing lattice work, which, besides the advantages before men- 

 tioned, has an exceedingly neat appearance. The front 

 stage is four feet two inches wide, and contains twelve 

 shelves ; the highest being two feet and a half from the level 

 of the walk. This will hold many plants ; over the hot wa- 

 ter pipes, which run close to the wall, is a shelf eight inches 

 wide, and made on a level with the sill of the front sashes. 

 The back border is filled up with coarse sand, to allow the 

 water to pass off* freely ; on this are placed all the large and 

 fine specimens of plants of all kinds, and their appearance 

 is highly beautiful, and the effect much more striking, es- 

 pecially upon entering the door, than when they are set up- 

 on stages. If any of the plants are very tall, the pots 

 should be sunk in the border. On the back wall is a trellis, 

 as seen in the section, on which may be trained any climb- 

 ing plants, such as passifloras of diff'erent species and 

 varieties, Multiffora roses, Lophospermum, &c. Over 

 the furnace and boiler a small stage is built, on which 

 are kept the Cactese, Crassiddcese, and other of the tribes 

 which like a dry and warm atmosphere, and which, in 

 green-houses in general, scarcely retain their life through 

 the winter. This stage maybe of any shape, but in this 

 house it is made with a square back to fit in close ; the 

 front formingaquarter of a circle, which looks extremely neat, 

 and covers the brick work. 



The end shed is built of common boards the back being 

 filled with tan in the same manner as the back and ends 

 of the house. The roof is not carried up quite so high as 

 that of the house, but is of the same pitch, front and back. 

 In front of the furnace door is a pit, four feet square, to ad- 

 mit of the easy introduction of fuel, &c.; across the opposite 

 end of the shed is a bench for potting plants ; underneath is
