Fig. 4 illustrates method of findinglengths and bevels of jack rafters. Lay out diagram a-b-e-a; with point e asa center, describe are a-d, and with f as a For cheek cut, find length, c, of bevel,Fig. 1, on any piece of stuff (rememberthat 5-12 of run and length, cut on length,will give cheek cuts of jacks for octagon (inthis case 2% and 10, cut on 10) ; transferlength of bevel to diagram, as i at g-h,Fig. 4, now transfer all the marks on line. renter, describe arc c-d.

I believe that with a careful study of theforegoing and my previous article on thesame subject, which appeared in the De- 52 The Carpenter cemher nnnibor of The Carpenter, any onewith a fair knowledge of roof framingshould be able to frame any roof of thiskind. It must be remembered that the run riseand radius of curves used in this article Removing a Splinter. When a splinter .has been driven deepinto the hand it can be extracted withoutpain by steam.
