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 . ans that one standardinch extends the length of 4 feet according to the re-duced scale. And so it is with each and every re-duced scale. These reduced scales are numerous and graduatedfrom Y% inch to the foot to 3 inches to the foot. Thelatter being just one-quarter full size (Standardmeasure). If the student examines the Instrument which iscalled a Scale, the triangular form most used bystudents, he will find a series of markings, one sectionof each of which is marked into 12 equal subdivisions,each of these subdivisions represents one inch or onetwelfth of a foot, according to the particular scalewhich is indicated by the figures at the extreme left *The illustration, Fig. 41, is made so the figures read one way only,whereas, in the actual instrument the figures are stamped so they facetoward the cove, both ways. This is to facilitate reading the figuresby looking over the scale, instead of from the near side. However, inactual practice the figures are often in an inverted 58 ARCHITECTURAL DRAWING of the markings. Immediately at the right of these12 small subdivisions will be noted a zero mark(indicated by a cypher thus: 0). This zero is apoint from which all measurements must be read. Tothe right of this zero mark will be seen a successionof figures (numbers) ranging from 1 to as many asare possible in the length of the instrument. It must be noted that some of these numbers areon the flat face of the wood, and some are in the coves,or concave surfaces, but it will be realized that eachline of figures are a system in themselves; i. e., all ina cove and reading in the same direction belong toone sy
