of shafts. Enter first the odd and then the even shafts. An 8 harness draw of this kind, of which three repeats are shown in Fig. 3, runs as follows: 1, 3, 5, 7, 2, 4, 6, 8. Fig. 4 is a 12 harness draw of the same class. * * * * * POINT DRAWS [Illustration: Fig. 5] * * * * [Page 10] [Illustration: Fig. 6] * * * * [Illustration: Fig. 7] * * * * [Illustration: Fig. 8] * * * * [Illustration: Fig. 9] [Page 11] Point draws are a combination of a regular straight draw from back to front and one from front to back, the first and the last shafts only being used once, while the rest receive two ends each in one repeat of the draw. Fig. 5 illustrates a regular point draw in 2 repeats on 10 shafts. It will be seen that 14 ends make a repeat; in fact, the number of warp-threads required for one draw will always be double the number of harness less 2, hence a 12 harness regular point draw will require 22 warp-threads for a repeat. The drawing-in draft illustrated in Fig. 6 is a slight variation of the regular point draw; it consists, as will be seen, of a draw from back to front, and also a full one from front to back, there by causing a _double point_. Another change from the regular point draw is illustrated in Figs. 7 and 8; this class may be called _Broken point draws_, because a new draw is begun before the other one is complete. Fig. 9 also comes in this class and represents a _zigzag draw_ on 10 harness. The drawing-in drafts which we have described under the head of "Point draws," are used mostly to obtain the various pointed and zigzag effects. * * * * * SECTION DRAWS [Illustration: Fig. 10] * * * * [Page 12] [Illustration: Fig. 11] * * * * [Illustration: Fig. 12] * * * * [Illustration: Fig. 13] * * * * [Illustration: Fig. 14] * * * * [Page 13] [Illustration: Fig. 15] This division of drawing-in drafts is used e
