Excerpt from How to Read a Drawing
The understanding of a drawing has appeared to many who are not familiar with this branch of education to be a very difficult study. It has been the writer"s province to know that there are a vast number of mechanics who look upon drawings with awe, thinking that to become proficient in the understanding of drawings they first must have scholarly or technical knowledge. It is the purpose of this book to show that this is a very erroneous idea, it being a fact that this branch of education requires less study than almost any other branch of useful knowledge; and all the education necessary is, that the student be able to read and understand the English language.
As to its usefulness, I doubt if there is any branch of education that compares with it; for by drawings we can express our thoughts and desires more clearly and concisely, and they can be understood more readily, than by any other system known to the civilized world. In the commercial or industrial world no work of consequence is carried on without them, and, from the making of a special bolt to the building of a railroad, drawings are necessary.
Who then, realizing this, can afford to be without this knowledge? Surely not those whose wages are small, for their wages will always be small unless they acquire useful knowledge which will tend to better their conditions in life; surely not those in the higher stations of life, for unless they understand drawings they must depend solely upon some one else who has this knowledge, in order that their desires may be carried out. The manager, purchasing agent, superintendent, foreman, mechanic, clerk, shopman, or laborer, will find this knowledge to be a stepping-stone toward success.
