Excerpt from A Course of Instruction in Machine Drawing Design: For Technical Schools and Engineer Students Practice in machine drawing does more for the student than merely teach him to use his instruments skilfully, or to properly represent objects by plan, elevation, and section for he is at the same time acquiring an intimate knowledge of the construction of the thing drawn. Hence forth the observant student who has been drawing, say an engine connecting rod, compares every new connecting rod he sees with the one he has drawn. The eye sees what it possesses the power to see, and every new example with which he becomes thoroughly familiar, by drawing it, enlarges his power of Vision, and enables him to see with advantage many things which would otherwise pass before him unobserved.
