Illinois State Academy of Science THE HE next meeting of the Illinois State Academy of Science is to be held at Rockford College, ROCKFORD, APRIL 27-29. The tentative program that is in preparation provides forThursday afternoon, business meeting, general session. Thursday evening, general session, two addresses, one of which is the address of the retiring President. Friday forenoon, general session, address, followed by a symposium on the "Structure of the Atom." The atom of the physicist as well as that of the chemist will be discussed in a manner so as to be equally intelligible to the geologist, biologist or mathematician. Friday afternoon, sectional meetings. Academy banquet at six o'clock at Rockford College. Friday evening, general session, address by Professor MacMillan of the department of astronomy, University of Chicago, on "Cosmogony." Saturday, field trips to interesting points near Rockford, the Chamber of Commerce of Rockford and Rockford College as hosts. Plan to attend the entire program. The program committee is pleased to announce that the Illinois Branch of the Mathematical Association of America will meet in affiliation with the Academy all day Friday, and Saturday morning. Those desiring to present papers before the various sections of the Academy should send titles direct to Secretary C. Frank Phipps, State Teachers College, DeKalb, Ill. The program will be mailed on April 15. The program committee is desirous of bringing the activities of the Academy to the attention of as large a number of scientists as possible. To this end may we not have your cooperation? Please call the attention of fellow scientists to our State Academy, its purposes, scope, and accomplishments. The new arrangement of our affiliation with the American Association for the Advancement of Science, whereby one may become a member of both for the price of the latter, is particularly attractive. More than 100 Illinois scientists took advantage of this combination offer last year. Those interested should address the chairman of the Membership Committee, Professor C. F. Hottes, University of Illinois, Urbana, Ill., who will gladly forward the necessary blanks. It is expected that a number of scientists from the Wisconsin Academy of Science and the Beloit Science Club will be present. Dr. C. T. Knipp, Chairman, H. C. Cowles, C. F. Phipps, Program Committee. SIX HUNDRED COURSES OFFERED AT THE UNIVERSITY OF CHICAGO FOR THE SUMMER QUARTER. More than six hundred courses are to be offered at the University of Chicago for the summer quarter beginning June 19 and ending September 1. They will include those in Arts, Literature, Science, Divinity Law, Medicine, Education, Commerce and Administration, and Social Service Administration. The first term will begin June 19 and the second term July 27, and students may register for either term or for both. The last summer quarter attendance was the largest in the history of the University-6,458. THE REORGANIZATION OF MATHEMATICS IN SECONDARY EDUCATION. The Final Report of the National Committee on Mathematical Requirements is to be distributed free of charge to all interested in securing a copy. The complete report of the National Committee on Mathematical Requirements is in the press and will, it is hoped, be ready for distribution in April. It is published under the title "The Reorganization of Mathematics in Secondary Education," and will constitute a volume of about 500 pages. The table of contents given below indicates its general character. Through the generosity of the General Education Board the National Committee is in a position to distribute large numbers of this report free of charge. It is hoped that the funds available will be sufficient to place a copy of this report in every regularly maintained high school library and also to furnish every individual with a copy free of charge who is sufficiently interested to ask for it. Requests from individuals for this report are now being received. They should be sent to J. W. Young, Chairman, Hanover, New Hampshire. Individuals interested in securing a copy of this report are urged to send in their requests as early as possible. If the number of requests received exceeds the number the committee is able to distribute, the earlier requests will receive he preference. The table of contents of the report is as follows: Part I. General Principles and Recommendations: Chapter I A Brief Outline of the Report. Chapter II Aims of Mathematical Instruction-General Principles. Chapter III Mathematics for Years Seven, Eight and Nine. Chapter IV Mathematics for Years Ten, Eleven and Twelve. Chapter V College Entrance Requirements.

Forty per cent of the developed water power of the world is in the United States, where water wheels having a capacity of 9,243,000 horsepower have been installed, according to a recent statement of the United States Geological Survey, Department of the Interior. The leading States in developed water power are New York, with 1,300,000 horsepower, and California, with 1,111,000. These state totals compare favorably with those for some of the most progressive countries in water power development in Europe, where France leads with 1,400,000 horsepower. Norway has 1,350,000 horsepower, Sweden 1,200,000 horsepower, and Switzerland 1,070,000 horsepower. The largest percentage of power has been developed in the New England States, where the capacity of the water wheels installed is 1,381,000 horsepower and the estimated potential power at low water without storage is 868,000 horsepower. In the Pacific Coast States-Washington, Oregon, and California-the capacity of water wheels installed is 1,893,000 horsepower and the potential power at low water without storage is 11,500,000 horsepower. The largest water-power development in the world is at Niagara Falls, where the plants in operation have a capacity of 870,000 horsepower, of which 385,500 horsepower is on the United States side. The capacity of the plants at Niagara is being increased by 114,500 horsepower in the United States and 300,000 horsepower in Canada. Other large plants are one of 170,000 horsepower on the Mississippi at Keokuk, Iowa, from which power is transmitted to St. Louis, and two plants aggregating 268,500 shorsepower on St. Maurice River in Canada, from which power is transrepitted to Montreal, Quebec, and other cities. Canada ranks next to Cha United States in water-power development, with 2,418,000 horsea cofer, or over 10 per cent of the world's total. If therope has one-third of the developed water power in the world. is able tants at Rjukan, in Norway, have a total capacity of 239,000 horseThe tand at Trollhattan Falls the Swedish Government has installed Part I. of 155,000 horsepower. At Lake Fully, in Switzerland, the ly high head of 5,413 feet is utilized. France, Italy, Germany, Sweden, and Switzerland have each developed more than horsepower. Chapte Cha Asia, Japan, with 1,000,000 horsepower, and India, with only 150,000 horsepower, are the foremost countries in water-power development. New Zealand has developed only 45,000 horsepower but it rapidly increasing this amount. Australia has practically no developed water power. The island of Java has 56,000 horsepower developed or to be developed by plants under construction. Africa possesses only 11,000 horsepower of developed water power. The total potential water power of the world is estimated at 439 million horsepower at low water, of which 62 million horsepower is in North America and 28 million in the United States. Africa is richest in undeveloped water power, with 190 million horsepower; Asia has 71 million horsepower, South America 54 million horsepower, and Europe 45 million horsepower. The World Atlas of Commercial Geology, Part II, Water Power of the World, which has just been published by the United States Geological Survey, summarizes all present knowledge of that subject, mentions briefly some of the world's largest water-power developments, and gives estimates by countries and by continents of the developed and undeveloped water power. It includes 37 pages of text and 10 maps and is sold for $1 a copy.
