This is best seen in the repro-duction of the photograph, where the side sheet is shownas coming down straight from a pwint just below thechownsheet and the sloi>e of the back head is cared forby its own Hanging, which has a depth of something morethan 12 in. at the bottom, in excess of that at the top. The grouping of the staybolts at the lower front cor-ners is slightly changed from the common practice by a.

The distribution of these staybolts followsa usual practice of using a complete installation in thethroat sheet and side sheets up to the crown sheet andthen putting in four rows across the top at the front endto act as sling stays and then using rigid stays over thebalance of the surface of the roof sheet.
