Book excerpt: Excerpt from A Little Book on Map Projection This little book is intended for the use of pupils in Secondary Schools, Central Schools, Higher Elementary Schools, and the Senior classes of those ordinary Elementary Schools in which special attention is given to practical geography. Apart from the Appendix, except in one paragraph which is not essential, no knowledge is assumed of even the Trigonometrical ratios. In the Appendix a few examples are given of the application of higher mathematics to map projection. The writer is indebted for much information to the work on Map Projections by Arthur R. Hinks, M. A., F. R. S. (Cambridge University Press, 1912). The student who desires to calculate map projections other than those of the simplest type, or to estimate the errors of scale or form in any map, should study Mr. Hinks' book. The object of the present writer is description rather than calculation and, except for the sake of illustration in the Appendix, only the simplest calculations have been used. A special feature is that all the projections, except Fig. 15, are drawn to the scale of a globe two inches in diameter, which differs from the scale of 1: 250,000,000 by only one quarter per cent. The projections are, therefore, directly comparable one with another. The reader is advised to draw the projections contained in this book, or parts of them, to the scale of the school globe and to compare the meridians and parallels with those on the globe for different latitudes and longitudes. A few illustrations have been introduced from mechanics, physics, and geometry, which may appear to have but a very remote connection with geography, but they will afford subjects for lessons which will appeal to many pupils, and lead to an increased interest in map projection. It is very undesirable that the subjects of school study should be separated by "water-tight bulkheads." About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
