Instrumental music classes in the public schools of Tulsa, Oklahoma, have experienced a phenomenal growth during the past twenty years. Prior to this period, opportunity for instrumental music expression was limited to the high school band and orchestra,which rehearsed outside of school hours. No instruction other than this was provided and the student who wished to play in the school band or orchestra studied first from private instructors. In this study the investigator has examined a great many devices for measuring capacities and aptitudes which are known to the profession. He has attempted to evaluate these procedures in the light of sound educational philosophy. He has set forth a plan which he believes will materially improve the instrumental program through discovering unsuspected musical capacity and through sound guidance in the selection of suitable instruments.

For four hundred years the Red River Valley has been the battleground between contending Indian tribes and European races, and for almost three hundred of these years the river has been a disputed boundary line, either between rival nations, or between neighboring states of our country. The river has never been of much importance as a commercial route, yet very few rivers in all the United States have played so an important and persistent a part in this history of their sections as the Red River has played in the history of the Southwest.
