Présentation de l'éditeur
Having been for several years engaged in teaching Architectural and Mechanical Drawing, both in the High School of Baltimore and to private classes, I have endeavored without success, to procure a book that I could introduce as a text book; works on Geometry generally contain too much theory for the purpose, with an insufficient amount of practical problems; and books on Architecture and Machinery are mostly too voluminous and costly, containing much that is entirely unnecessary for the purpose. Under these circumstances, I collected most of the useful practical problems in geometry from a variety of sources, simplified them and drew them on cards for the use of the classes, arranging them from the most easy to the more difficuh, thus leading the students gradually forward; this was followed by the drawing of plans, sections, elevations and details of Buildings and Machmery, then followed Isometrical Drawing, and the course was closed by the study of Linear Perspective andS hadows; the whole being illustrated by a series of short lectures to the private classes. I have been so well pleased with the results of this method of instruction, that I have endeavored to adopt its general features in the arrangement of the following work. The problems in constructive geometry have been selected with a view to their practical application in the every-day business of theE ngineer, A rchitect and A rtizan, while at the same time they afford a good series of lessons to facilitate the knowledge and use of the instruments required in mechanical drawing. The definitions and explanations have been given in as plain and simple language as the subject will admit of; many persons will no doubt think them too simple.
