Excerpt from Problems in Stone Cutting: In Four Classes for Students of Engineering and Architecture This manual has been composed with the idea of represent ing, essentially, every class of structures, and every principal variety of surface, so as to make it most widely useful to the student in solving any other problems which he might meet. The student needs, desires, and appreciates explicit detailed information in due abundance, not to prevent him from think ing for himself, but to train him to do so by examples fully explained. On this principle, and supported by the best author ities, I have discussed the few problems which could be admit ted within the proposed limits, SO thoroughly as to satisfy, I trust, all who enjoy the most - indeed, the only universally -available help, viz., a printed text. I have attached scales and dimensions to the problems, which teachers and students may use or not, according as they prefer to work as if drawing actual structures for practical purposes, or to study the purely geometrical principles and Operations involved. In either case, the figures should be made, generally, from two to three times as large as those of the plates in this volume, carefully following the text, and under frequent inter rogation by the teacher, in doing so. I should add that this work presupposes a fair acquaintance with descriptive geometry, though many of its problems could be understood after the study Of my Elementary Projection Drawing. It is, how ever, complete in itself in regard to several collateral topics required for use in it, and not as conveniently found else where.
