666 Design for a small Green-house or Conservatory. 



Fig. 126. is one of the upright lights, 6 ft. 8 in. to the spring 

 of the arch, and rising 8 in. in the centre, fitting 

 into a corresponding frame, and secured merely 

 by three bolts (k k k). jj are two windows, 

 14 in. deep, opening upon horizontal pivots at 

 their centre ; the panes of the glass 4^ by 4. 



Fig. 127. is a slight sketch of the elevation, 

 with the doors and lights removed for the sum- 

 mer; but not being done upon a scale it does not 

 give the proportions, for the height of the para- 

 pet, including all the distance from the crown of 

 the arches to the coping, is only 2 ft. 6 in., and the pillars

between them 23 in. wide, bevelled off to 10 inside. The 

 glazing of the roof is curvilinear, each pane being only 5^ in. 

 by 4 ; the laps rather more than one eighth of an inch, with 

 putty between, except a small opening at the centre; but 

 where the best crown glass is used, and the panes so narrow, 

 I do not conceive putty necessary, where merely the usual 

 green-house temperature is wanted. Not only is the original 

 cost, and the expense of repairs, most considerably reduced 

 by adopting panes of small dimensions, but breakage from 

 frost is completely prevented, when the laps do not exceed 

 one fourth of an inch. Though my house is 43 ft. by 18, the 

 cost of glazing did not amount to 50/. 



If it should be desirable to have a bed or beds, ample direc- 

 tions are given in your Magazine (Vol. I. p. 108.), with this addi- 

 tional caution only, that where the substratum does not afford a 

 ready escape for the water, drains should be made on the out- 

 side, and far below the foundation of the house all round ; small 

 openings being left in the foundation walls, to allow the water 

 to pass freely from the bottom of the beds. Whilst speak- 

 ing of those beds in which camellias usually find a place, I 

 cannot help expressing a doubt whether it is not more advis- 

 able to have the plants in pots plunged in the soil, should
