UHEMISTRAY Chemistry is one of the great forces which is determining the civilization and development of mankind. The physician makes abundant use of it in combatting disease, the progressive manufacturer in improving processes and products of manu- facture, the sanitary chemist in the treatment of municipal water supply and sew- age, and the metallurgist in the extraction of metals from their ores. Progress in other sciences has been in a measure based on the discovery of the chemist. The scope of chemistry is so great that some knowledge of the subject is essential to those who wish to keep in touch with the progress of civilization. The course as offered gives as much attention as possible to the practical sides of the subject without neglecting the basis for its advanced pursuit. Some time is devoted to the consideration of the fundamental laws, theories, and principles of the subject. These must be understood for they serve as a foundation upon which the applications rest. Among the many phenomena of every day life which require some knowledge of chemistry for their proper interpretation may be mentioned, the decay of wood, rusting of iron and tarnishing of metals, combustion, bread-making, souring of milk, the conversion of cider into vinegar, the proper use of cleaning powders, and TWENTY-EIGHT

the nature, preparation and digestion of food. Along with the study of the various elements and compounds, the use of these substances in the manufacture of some of our great commodities is shown as, for example, explosives, mortar and cement, soap, crude oil and coal tar products, sugar, paint and steel. Department of History and Government ANCIENT HISTORY The aim of this course is to give a real background for the student's knowledge of present social, political, industrial, religious and economic conditions. A reason for each of these conditions is to be found some where in ancient or modern Euro- pean history. The object is to lead the pupil to see that civilization is not a product of chance but a slow and gradual development. Emphasis throughout the year is on the present and its relation to the past rather than on the past and its relation to the present. The point of view is from the present back to the past. Questions asking explanation of present institutions in the light of past history are a daily part of the course. lt is hoped that in this way the interdependence of past and present may be partly shown, although it is recognized that a year course in Modern European History should be added to the history work of the High School before the work can be thoroughly done. ECONOMICS Many of the well-known principles of economics are encountered by the average High School student before he reaches the last of his High School work, but without a study of these economic laws and conditions he fails to get an adequate concep- tion of their operation and effect. The knowledge gained by experience often is not organized and related consciously and this is best done in the class room. Ap- plication of the law to outside conditions is asked for frequently and examples of the practical working of economic law are called into discussion daily. A correla- tion between the theory of economis- and current history is also attempted and this phase of the work will be more fully developed next year with the hope the more vital live issues may be introduced and discussed from their economic standpoint. ENGLISH HISTORY This course is given with a two-fold purpose. One is to trace the development of the Anglo-Saxon race as a matter of world history, and the other is to provide a proper foundation for the study of American History in the Senior year. The lat- ter point of view colors the work quite largely. All the great landmarks in the strug- gle for freedom by Englishmen from the granting of Magna Charta in 1215 to the Revolution of 1911 are emphasized. Students are led to see their own history in the field covered prior to American colonial settlement. Those events that brought about the migration of the Puritans from England in the Stuart reign. and later the revolt of the colonies so formed and their consequent independence receive especial attention. CIVICS A systematic study of the structure and development of the American Govern- ment, national, state, and local, with emphasis upon actual workings. Current events as well as historical in executive, legislative and judicial departments of national and state governments are used to illustrate the various provisions in the constitution. AMERICAN HISTORY The place of American History in the American High School is undisputed and no justification for the time spent in its study is needed. The opportunity offered to TWENTY-NINE
