The second source from which fibre is extracted is that from
the stems of plants such as flax, hemp, jute and the like. A photographical
reproduction of a group of hemp plants grown by the Authors appears
in Fig. 6. A female plant is illustrated on the right, while the
remaining two which are taller are male plants.
A thin cross-section cut from the stem of such a plant exhibits
the characteristics in Fig. 7, in which A is the cuticle or outer
bark, B is the woody part, and C the pith. The fibrous layer is
between the two dark circles D, and a few groups of fibres in
this layer are indicated by the letter E. Here, again, a considerable
amount of extraneous matter must be separated from the bast layer,
and when separated, the latter appears in the form of long ribbons.
The cuticle and bast layer were originally stripped from the plants;
the former were then placed in the mouth so that the saliva could
aid in the separation of the fibrous layer to produce finer threads.
And although at the present time this method is practised for
thread making in many primitive communities, it need hardly be
said that much more efficient methods have long been practised
for commercial purposes, such methods being known by the technical
terms "retting," "breaking," and "scutching."
