fri-IE ORACLE 69 BOTANY Although man has gone into the depths of chemistry, nature has not given him the key to the process of manufacturing starches and sugars from moisture and carbon dioxide. Since nature has retained this secret, man is dependent upon plants for his existence. The great civilizations of the world developed where conditions fav- oured the growth of rice, wheat and corn. Botany progressed slowly be- cause it had to depend upon phy- sics and chemistry for its develop- ment. While studying the struc- ture of roots, stems, leaves and fiowers, we found the microscope and magnifiying lens indispens- able. The High School has provid- ed two Busch microscopes and a set of magnifying lenses for the pupils. There is also a very good set of slides at our disposal. The first attempt to classify plants was made by Theophrastus of 370 to 285 B.C. Since his time thousands of plants have been classified. In our course this year, while studying the classification of plants, we began with a one-celled plant, the Thallophyts. Far up the scale we studied plants with very elaborate fibro-vascular systems by which food could be carried from the roots to the leaves. ' The scientific study of plants effect our modern life greatly. In agriculture, by scientific selection and the crossing of varieties, our grains and other plants have been greatly improved. Though much progress has been made, we must remember that mother nature has retained her truly great secret. ' - ORMA STEVENS, Grade XIII MATHEMATICS Boom! a United States coast battery fires a shell in target prac- tice and scores a bull's-eye fifteen miles out at sea. Construction gets under way on the new Peace bridge spanning the Niagara. Man rides the skies at thirty thousand feet. In short, the seven wonders of the world are sinking into oblivion. This has been made possible by the highly complex science--Mathematics. Whence its origin? Since 2000 B.C. mathematicians have created, developed, and compiled the fac- tors of this science-consisting of four branches: arithmetic, alge- bra, geometry and trigonometry- until today it is one vast compli- cated subject. The more we study mathematics, the more interesting we find it. It provides a solution for our curiosity whether it con- cerns the size of the earth, the distance of the stars or the time of the onset of the seasons. Such a curiosity, accompanied by neces- sity, is responsible for its origin. It was created, it is believed, by ancient priestly calendar makers. But mathematics is not only a factor for the solution of our curi- osities. Its importance in our lives is, perhaps, greater than we rea- lize, for it is the foundation of trade, the essence of exchange, the cornerstone of engineering, and, above all, the basis of educa- tion. Without mathematics none of the exact sciences could exist. Ships, cars, trains and the more modern aeroplane and submarine are brilliant products dependent in every detail on mathematics. Unfortunately, nations in our time have co-ordinated mathema- tics with the development of explosives and have used them
