30.--Additional investigations suggested 228

Experience had demonstrated the propriety of some changes in the
alphabet and a considerable enlargement of the scheme as given in the
first edition of the work, and in the second Major Powell has made many
modifications. The schedule of relationship was so large that graphic
representation was considered necessary, and charts were prepared which
it was thought both the student and the Indian could follow it with
comparative ease. Experience has shown that the idea was well founded.

As in the first edition, blank spaces were given after each schedule for
such additions as might suggest themselves to the collector; and to
further facilitate the work separate alphabet cards of convenient size
accompanied the volume.

This publication has not been long enough in the hands of collectors to
meet with great returns, though a sufficient number have been received,
filled or partly filled, to justify the Bureau in anticipating, in the
not distant future, the receipt of a body of material prepared according
to scientific methods which, when published, will prove a valuable
contribution to this branch of ethnologic research.
