Architectural drawing : a textbook that combines the parctical instructions and examples that the student needs, with the suggestive programs, supplementary problems, etc, required by the teacher, written by an architect of wide experience who has also taught the subject for years at Teachers' College, Columbia University, and Mechanics' Institute, New York . re, with the little fingerhooking over the back edge, just as first described,and thus insuring a perfect contact ready for a freshbeginning. The movement of sliding the left handover the blade is repeated every time it is desired touse a set-square in contact with the T-square. The Set-Square—The function of the set-squaresis to facilitate the making of short lines perpendicularor at an angle to lines drawn by the assistance of aT-square, also to make short lines in any direction inconjunction with the T-square or another set-square. Two set-squares or triangles have been described,and the method of handling obtains to both. In otherwords, the two set-squares are used in one and thesame manner, the only difference being the angularityof the line drawn. It may be found convenient attimes (very rarely, however), to use two set-squaresconjointly, but as an alternative, in architecturaldrawing, it is much more convenient to use one set-square and the T-square in combination. The method. 32 ARCHITECTURAL DRAWING for doing this, is to place one edge of a set-squareparallel to the line to be duplicated, then bringingthe T-square blade, with its upper edge resting againstthat edge of set-square, most conveniently remotefrom the edge which parallels the line to be drawn;and then, by sliding the set-square along the edge ofblade of T-square, any number of lines each parallelto the other may be made. In this operation, it becomes extremely necessarythat both T-square and set-square be held rigidly inplace, until all needed lines are drawn. There are times when it is convenient to use a set-square independent of the T-s
