In preparing the report on the manufacture of paper from hemp hurds it became eveident that a short discussion of the agricultural aspects of this material should be included in the publication. Such an article was prepared, therefore, and the two reports are here presented together.


THE PRODUCTION AND HANDLING OF HEMP HURDS.

By LESTER H. DEWEY, Botanist in Charge of Fiber-Plant Investigations

WHAT HEMP HURDS ARE.

The woody inner portion of the hemp stalk, broken into pieces and separated from the fiber in the processes of breaking and scutching, are called hemp hurds. These hurds correspond to shives in flax, but are much coarser and are usually softer in texture.
