is stuck into the ground, pointing in the direction pursued, with a
number of cuts, notches, or marks corresponding to the number of days
which the party spent after leaving the last camp until leaving the
present camp, serving to show to the recruits to the main party the
course to be followed, and the distance.

A hunting party in advancing takes the same precautions as a war
party, so as not to be surprised by an enemy. If a scout ascends a
prominent elevation and discovers no game, the blanket is grasped and
waved horizontally from side to side at the height of the shoulders or
head; and if game is discovered the Indian rides back and forth (from
left to right) a short distance so that the distant observers can view
the maneuver. If a large herd of buffalo is found, the extent traveled
over in going to and fro increases in proportion to the size of the
herd. A quicker gait is traveled when the herd is very large or haste
on the part of the hunters is desired.

It is stated that these Indians also use mirrors to signal from one
elevation to another, but the system could not be learned, as they say
they have no longer use for it, having ceased warfare(?).

SCHEME OF ILLUSTRATION.

In the following pages the scheme of graphic illustration, intended
both to save labor and secure accuracy, which was presented in the
_Introduction to the Study of Sign Language_, is reproduced with some
improvements. It is given for the use of observers who may not see
that publication, the material parts of which being included in
the present paper it is not necessary that the former should now be
furnished. The TYPES OF HAND POSITIONS were prepared for reference
by the corresponding letters of the alphabet to avoid tedious
description, should any of them exactly correspond, or by alteration,
as suggested in the note following them. These, as well as the
OUTLINES OF ARM POSITIONS, giving front and side outline's with arms
pendant, were distributed in separate sheets to observers for their
convenience in recording, and this will still be cheerfully done
when request is made to the present writer. When the sheets are not
accessible the TYPES can be used for graphic changes by tracing the
one selected, or by a few words indicating the change, as shown in the
EXAMPLES. The OUTLINES OF ARM POSITIONS can also be readily traced for
the same use as if the sheets had been provided. It is hoped that this
scheme, promoting uni
