C. H: S. General Science, A Book of Projects by Edgar A. Bedford, Dewitt Clinton

High School, N. Y. C. Pages XXIII +387 +11. 1372X19 cm.

Cloth. 1921. Allyn & Bacon, Chicago. This is one of the best books of the kind which has come to the attention of the writer. No particular part of the sciences is treated more than the others. In fact, there is a fair division of the discussion among the various sciences treated. There has been an attempt made to cultivate a spirit of inquiry and open-mindedness. Also, to put the pupils in possession of certain fundamental truths which give an explanation of everyday life and to help the pupils learn a few of the forces and their effects which surround them. The projects have been selected largely

The Teaching Museum should include enlarged models of the different protozoa.

Accurate models of the typical laboratory forms will clear up much of the vagueness that confuses the student in his early dissections.

Models showing the embryological development of Amphioaus, Frog, etc., will enable the teacher to present the principles of animal growth and development in a vivid clean cut fashion.

from everyday phenomena. The illustrations have been selected with reference not only to their familiarity to the pupils but also for their value in bringing home many of the facts of nature. It is profusely illustrated with drawings in half-tones, of which there are 296, and which have been especially selected for this work. The projects begin with bold face type. It is splendidly written, the diction is fine, and put up in a way that the young pupil will understand. The type is printed in ten point type on splendid paper. It is a text which should be in the hands of every general science teacher.

C. H. S. Geography of Illinois, by D. C. Ridgley, Illinois State Normal University.

385 pages. 22 chapters and many illustrations. University of Chicago Press. 1921. $2.65. Ridgley's Geography of Illinois will serve as a model for the development of similar studies in other states. In the modern text for elementary geography, the "state supplement" has reverted to the style of the gazeteer. The pupil finishes the elementary school too frequently, in ignorance of the simple facts of his own state and community. This text interests the citizen, stimulates the teacher and pupils. It is an authoritative geographical study of Illinois in compact and convenient form.

The geographical features, natural resources, and climate are clearly set forth. The response of people to these geographical influences are illustrated by the development of the different occupations.

The chapter upon weather and climate of Illinois, presents the climatic problems in clear statements, excellent pictures and graphs. This chapter is followed by one upon native vegetation which arouses the interest of those living in the Middle West.

The chapters on the natives and the coming of the white man unfold the familiar stages of conquest, hunter, pioneer, and permanent settlement. The rapidity of settlement is remarkable and the geographic influences which controlled the migration are clearly set forth.

The growth of transportation is presented in chapter four. The part of transportation in the development of a great state suggests a basis for civic lessons in good roads and available markets. As the land (transportation) occupation in Illinois has passed rapidly through different stages, so transportation of all kinds has undergone remarkable changes.

It has three hundred illustrations of maps, charts, graphs in black and white. Many of the important maps are splendidly colored to emphasize important details.

The excellence of this text will invite its wide use among teachers and pupils of geography. It should be followed by similar texts for other states.

The compilation shows excellent judgment in selection of material and organization. The text is a necessary handbook for teachers of regional and commercial geography.

L-270 Gaertner Polariscope
A new design embodying all that was desirable in the old Nor-
remberg types together with some distinctly novel features.
The optical parts are mounted on a single rod which can be tilted
and clamped at any angle to suit the position of the light source
and the convenience of the observer. Any of the optical parts
can be swung out of position when not in use or removed en-
tirely from the rod.
The polarizer is a sheet of plane glass which can be rotated either
to reflect light into the analyzer or to the mirror at the bottom
of the rod.
