ists the possibility of utilizing the agricultural waste already
produced on 10,000 acres of hemp lands instead of securing, holding,
reforesting, and protecting 40,500 acres of pulp-wood land.

The annual growth per acre, although decidedly in favor of hurds, has
little bearing on the project, because the utilization of the hurds is
subordinate to the raising of hemp, and the paper manufacturer probably
could afford to use only hurds resulting from the hemp industry.

=PHYSICAL TESTS OF THE PAPERS PRODUCED.=

Samples of paper produced in the seven tests were submitted to the
Leather and Paper Laboratory of the Bureau of Chemistry. The report of
that bureau on its tests is given in Table III.
