THE COLD GRAPERY. 145 



the front of which were placed upright sashes two and a 

 half feet in hight, and on these the gutter. From the 

 gutter was sprung the bars, ten inches apart each way, 

 running on the east side clear to the ridge pole ; on the 

 west framed to within 2 feet of it, so as to give room for 

 lifting sashes. These were two feet wide by six long. 

 To these sashes, eight in number, were attached Hitch- 

 ing's patent ventilating apparatus, which by turning a 

 crank opens these sashes from one to twenty-four inches, 

 as desired. The front sashes may be made so that 

 every alternate one can open outward. The glass used 

 is known as second quality English or French, 8 x 10 

 inches, and put in without the use of any putty on 

 the top of the glass, the manner of glazing being to 

 " bed" the pane in soft putty, pressing it down tightly, 

 and then tacking in the glass with large glazing points 

 about the size shown in fig. 58; 

 we find it an excellent plan in 

 glazing to turn up the edge of 

 these points as in fig. 59, so that 



they can catch under the edge of Fig. 53. Fig. 59.

place, otherwise it would slip down, and give a great deal 

 of trouble. Glaziers will not use the points in this way 

 unless compelled to do so, as it takes a somewhat longer 

 time. Glass should never be lapped more than a quarter 

 of an inch, if much more, the water gets between the 

 laps, and when it freezes the glass is cracked. With 

 these instructions about the erection of the glass and 

 wood-work, any intelligent mechanic should be able to 

 build from the plan given. Provision for water should be 

 made by building a cistern inside the grapery, say four 

 feet deep by eight feet in diameter, or that capacity in an 

 oblong shape would be better. This cistern can be sup- 

 plied by water from the roof, having a waste-pipe for 

 overflow. These general directions for such a structure
