THE AMATEUR’S KITCHEN GARDEN. 35 
in the garden of the amateur, where alterations are as a rule 
constantly being made. The principal point is to make the 
joints to fit nicely, and to fasten rafters down with screws 
previously well greased to prevent their rusting. 
The sashes must be five feet four inches in length, and three 
feet five inches ill width, to fit a frame of the width above 
mentioned, with rafters three feet six inches apart. The 
wood-work should be two inches in thickness, and each light 
have three sash bars, and be glazed with glass nine and a half 
inches wide ; and by allowing one inch for the outside frame- 
work, and a third of an inch for each of the sash-bars, it will 
be found that glass of the size recommended will fit without

squares is not of so much importance, but those twelve inches 
in length will have the best appearance, as the length will be 
proportionate to the breadth. 
We now come to the span-roof form. This is drawn on 
a smaller scale, as the lights are in two, and a greater width of 
frame can be allowed without the lights being too heavy 
to move about. This frame is seven feet wide, one foot high 
at the sides, and two and a half feet high in the middle. The 
lights are three feet nine inches in length, and have the handles 
fixed at the bottom instead of the top, but in other respects 
they are made in precisely the same manner as those for the 
lean-to. There is a difficulty in handling the lights of a span- 
roof which does not occur with those of the lean-to. They 
cannot be drawn out of the way when watering, but must 
either be held up with the hand, or a wooden support, or be 
lifted bodily away. The centre-piece against which the lights
