Anothermethod of ascertaming the strength of the pick is to place the handflat on the top of the box, with the little finger just over the edgeof the slot in which the picker-stick moves, known as the picker-race, thus covering the slot to the extent of almost four the picker presses sufficiently hard against it to push the handaway, the stick has too strong a pick and too long a range, whichmay be remedied by letting out the lug-strap. Occasionally thepick-shaft drops slightly and allows the back end of the cone torest on the cam, m which case a hard pick results. Raising it upagam will ease the pick. When the pick is found to be all right,the box pressure must be increased, and this must be done with 218. WEAVING 205 allowances for future changes in speed and atmosphere. A veryslight change is usually sufficient, and many times arranging thecheck-spring at the end of the box will obviate the difficulty. Asfixing for present conditions generally necessitates altering backagain for the next change, the best method is to fix for averageconditions, and thus save time and work. 13. An early or late pick will cause the loom to bang shuttle should- commence to move when the crank is on thetop center. When the picking motion is late, it may readily benoticed by watching the shuttle as it leaves the shed to enter thebox. The shed closes upon it and the tendency is for the warpto become broken. Test the pick from both sides to see if bothsides are a little late. If so, the probable cause is that the drivinggears have slippe
