which is not sufficient for the easy passage of the woof. She inserts
her batten edgewise into this opening and then turns it half around on
its long axis, so that its broad surfaces lie horizontally; in this
way the shed is opened to the extent of the width of the batten--about
3 inches; next the weft is passed through. In fig. 42 the batten is
shown lying edgewise (its broad surfaces vertical), as it appears when
just inserted into the shed, and the weft, which has been passed
through only a portion of the shed, is seen hanging out with its end
on the ground. In Plate XXXV the batten is shown in the second
position described, with the shed open to the fullest extent
necessary, and the weaver is represented in the act of passing the
shuttle through. When the weft is in, it is shoved down into its
proper position by means of the reed-fork, and then the batten,
restored to its first position (edgewise), is brought down with firm
blows on the weft. It is by the vigorous use of the batten that the
Navajo serapes are rendered water-proof. In Plate XXXVIII the weaver
is seen bringing down this instrument "in the manner and for the
purpose described," as the letters patent say.

When the lower shed has received its thread of weft the weaver opens
the upper shed. This is done by releasing the healds and shoving the
shed-rod down until it comes in contact with the healds; this opens
the upper shed down to the web. Then the weft is inserted and the
batten and reed-fork used as before. Thus she goes on with each shed
alternately until the web is finished.

It is, of course, desirable, at least in handsome blankets of
intricate pattern, to have both ends uniform even if the figure be a
little faulty in the center. To accomplish this some of the best
weavers depend on a careful estimate of the length of each figure
