mechanically supplied to the fires.
The slabs, once considered as waste, contain much material that is now
utilized. From the live rolls, on which all the material falls from
the main band-saw, the slabs are carried off by transfer chains,
and by another set of five rollers to the "slasher," Fig. 50, which
consists of a line of circular-saws placed 4' 1" apart. This slasher
cuts up the slabs into lengths suitable for lath or fence-pickets.
Fig. 49. Or they can be resawn into 16" lengths for shingles or
fire-wood.

material lengthwise into laths.]

into lengths suitable for lath or fence-pickets.]

From the "slasher" the 4' 1" lengths are carried on by traveling
platforms, chains, etc., to the lath-machines, Fig. 51, where they are
sawn up, counted as sawn, bound in bundles of 100, trimmed to exactly
4' in length and sent off to be stored. The shingle bolts are
picked off the moving platforms by men or boys, and sent to the
shingle-machine, Fig. 52, where they are sawn into shingles and
dropped down-stairs to be packed. Shingle-bolts are also made from
crooked or otherwise imperfect logs.

Of what is left, a good part goes into the grinder or "hog," Fig. 53,
which chews up all sorts of refuse into small chips suitable for fuel
to supplement the sawdust if necessary. Band-saws make so little dust
and such fine dust that this is often necessary.

[Illustration: Fig. 51. Combination Lath-Binder and Trimmer. With this
machine the operator can trim the bundles of lath simply by tilting
the packing frame over from him causing the bundles to pass between
the saws, thereby trimming both ends at one movement.]

[Illustration: Fig. 52. Hand Shingle-Machine. This machine is used in
Sawmills in which it is desired to utilize slabs and trimmings by
sawing shingles therefrom, or to saw shingles from prepared bolts.]

If there is any refuse that cannot be used at all it goes to the
scrap-pile, Fig. 54, or to the "consumer," the tall stack shown in
Fig. 37, see p. 33.

Boards ordinarily sawn from logs are "slash-sawn," i. e., they are
tangential or bastard, each cut parallel to the previous one. By this
process, only the central boards would be radial or "rift" boards.
