2i8 AROUND THE YEAR IN THE GARDEN 



comers, are of exactly the same length. Mark the lines 

 for the outsides and ends plainly by stretching stout cord 

 or a garden Line to stakes set a couple of feet beyond where 

 each corner is to be, so that the points where the strings cross 

 will indicate the exact point where it is desired to have the 

 outside corners of the greenhouse. All the posts should be 

 set in very firmly; the best way is to pour concrete aroimd 

 the bases. Set the two corner posts first and line up the 

 rest carefully with these. The best way is to have the posts 

 a little longer than needed, and saw them off level after 

 they are set. 



The 2x4 inch eave plate can go into place next. And 

 then, leaving just enough room for a light of glass to go 

 in the 16-inch way, fit the 2x6 inch sill 16 inches below 

 this, mortising it out carefully to fit snugly about the 

 posts. The bevel or shoulder in the sUl should come just 

 even with the outside of the posts, so that the latter wiU 

 not be in the way of the glass, which may be put in, with- 

 out any side bars, in a continuous row. 



The walls may then be constructed fitting the boards 

 snugly under the 2 x 6-inch sUl, and working down toward 

 the ground. Put the ridge in place, being sure that it is 

 very secure and makes a water-tight joint with the side of 

 the house. (If this cannot be secured by the use of white 

 lead, use a strip of roofer's tin.) Then mark off carefully on 

 both ridge and eave the places for the sash bars. Then start 

 with one end bar, and nail the bars into place, using finishing 

 nails. Try every third or fourth bar with a light of glass to 

 be certain that you are getting them spaced exactly right. 

 The purlin, or pipe, which supports the sash bars does not 

 have to be directly on the middle. In this lean-to, for in- 

 stance, it comes a Httle to one side. Ascertain carefully, 

 however, just where it is to come, and mark the bars on the 

 bottom side with a chalk-line. Then, with the purhn clips, 

 fasten the purhn into place. Put the pipe post supports in 

 place, being careful to get them perpendicular and in fine, 

 and set the bottoms in concrete. Do not toiich the posts 

 while the concrete is setting, which will take two or three
