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 . sionof 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 system, and those on the flat faces and readingin one direction only, belong to another system. To read a scale; feet and inches are spoken of atthe reduced size, just as they are in the full size, orU. S. Standard. In marking figures on a drawing so as to representfeet and inches they are followed by apostrophes,one of them signifying feet and two of them meaninginches. Thus: 6 feet and 3 inches is written feet and inches being separated by a hyphen ordash. Some use a period or decimal point betweenfeet and inches, but the dash is better and less liableto confusion. If we would read 6-3 on a scale of y^ to the VM \ \ \ \ \ \ \ \ \ fa E~erT 3 TOOLS—IN PRACTICE 59 We would lay the scale on the drawing with the ^4scale markings close to and parallel with the line tobe measured, and read the feet in one direction and theinches in the other direction, in both instances startingfrom the zero mark. It must be observed that where there are two scaleson the same face, they must of necessity, be readfrom opposite directions: one from the left to right,the other from right to left. This applies to all scales, whether the wood onwhich the marks are printed be flat or triangular incross section. This one illustration as to the met
