CHAPTER II.
SAWMILLING.
The principal saws in a mill are of three kinds, the circular, Fig.
32, the gang, Fig.

33, and the band, Fig.34.The circular-saw, tho very rapid, is the most wasteful because of the wide kerf, and of course the larger the saw the thicker it is and the wider the kerf.
The waste in sawdust is about one-fifth of the log.

In order to lessen this amount two smaller saws, one hung directly above the other, have been used.

One saws the lower half of the log and the other the upper half.

In this way, it is possible to cut very large logs with the circular-saw and with less waste.
