Manual Of Topographical Drawing PDF Download

Excerpt from A Manual of Topographical Drawing Professor smith's Manual on Topographical Drawing first appeared in 1854, and was at that time the only American treatise of any extent on the subject. In the course of time, the plates became somewhat worn with age, and required to be redrawn. The text, also, although retaining its original value as a presentation of the subject, was found to differ materially in respect to the order of presentation from that adopted in our leading technical schools. It was thought, therefore, that some advantage might be gained, and the work better fitted for use as a text-book, by recasting it in accordance with what experience had shown to be a more acceptable arrangement of its several parts. The Editor, acting under the most liberal instructions from the Publishers, has endeavored to carry out the aims indicated above as thoroughly as time and other circumstances would per mit, and with the loyal purpose of preserving intact as much of the Author's text as possible. While it is quite certain that there is still much room for improvement in the work as now pre sented, it is hoped that the changes and additions in both the ten and plates will, in some degree, merit the approval of teachers. The intermingling of two separate writings on almost every page renders it inexpedient to attempt to point out all the changes which have been made. Nor is any discrimination necessary; instructors and others who are familiar with the original work will readily perceive the alterations. It may be stated in this connection, however, that the extensive additions which have been made in the first part of the work have been introduced in the hope of rendering it more serviceable to those who may not have the benefit of a teacher's guidance.
