Bird's-eye maple veneer is much more valuable and
requires more care than almost any other, and this is packed in cases
instead of tied in bundles. The drying process is usually a slow one,
and conducted in open sheds simply exposed to the air. Mr. Densmore's
invention will revolutionize this process, and already gives his mill a
most decided advantage.
The mill will cut about 30,000 feet of veneer in a day, and this cut can
be increased to 40,000 if necessary. Mr. Densmore has already received
several large orders, and the rapidly increasing demand for this
material is likely to give the mill all the work it can do. The timber
used is principally curled and bird's-eye maple, beech, birch, cherry,
ash, and oak. These all grow in abundance in this vicinity, and the
beautifully marked and grained timber of our forests will find fitting
places in the ornamental uses these veneers will be put to.

THE CONSTITUENT PARTS OF LEATHER.
The constituent parts of leather seem to be but little understood. The
opinions of those engaged in the manufacture of leather differ widely on
this question.
Some think that tannin assimilates itself with the hide and becomes
fixed there by reason of a special affinity. Others regard the hide as
a chemical combination of gelatine and tannin. We know that the hide
contains some matters which are not ineradicable, but only need a slight
washing to detach them.
