schools. Indiana has few large cities, so the Indiana plan covers this sort of case rather well. The professional and academic requirements are the same in both cases and the final 4-hour credit in the teaching of science is stiU required but instead of devoting so much time to one science it is recommended that the student take 68 hours in science as follows-"They must make a credit of two years, 24 hours each, in two and any two of the following fields: biology, physics, chemistry. They must further make a credit of 8 hours either in geography and geology or in physiology. They must make a credit of four hours in the professional academic course dealing with the problem of teaching science in the high school. The remaining eight hours of the 68 are treated as elective." There foUows this advice "Students should study these options with great care rememberingin each case that the license issued will be strictly limited to the subject studied. They should acquaint themselves with the probable requirements they will meet in the high schools where they hope to teach and take such group combmations as will give them license to do aU the work expected of them." I t is obvious that the student who thus takes a bit of this and a bit of that cannot hope to be the kind of chemistry teacher that this committee was appointed to help produce. While state laws are not all alike yet nearly everywhere the demands of the professional credits encroach on proper preparation in the major subject. Far be it from us to urge narrowness of preparation. We would rather urge breadth not only in science but in the humanities as well. However, with a four-year limit and with legal limitations in regard to so-called professional preparation we do not see how the above suggestions can be bettered. It is hoped that the reading of this report will stimulate much thoughtful discussion of the problem to the end that your committee may receive assistance in preparing a better one a t a later meeting.

Light Alloys May Be Metals of Future. America leads the world in the practical development of light, tough alloys for struchval purposes. Francis C. Frary of New Kensington, Pa., told members of the Amerioln Chcmical Society. There are only two light metals, aluminum and magnesium, which seem to face an increasing demand in the future, Mr. Frary said. Other light metals are chiefly used as chemical reagents, hut not for alloys. Magnesium-rich alloys are k i n g perfected and their use in aviation and other fields where lightness is the main consideration and cost relatively unimportant, is increasing. Aluminum alloys on the other hand are competing with brass and steel, especially in the transportation field. Sheet, castings, forgings. and structural shapes made of these alloys, have the strength of mild steel and only one-thiud its weight, Mr. Frary said, and their use d l rapfdly increase.4CWd Sen&
