More and more the fact is being recognized that among the chief qualifications of the successful business man is the ability to use plain, clear-cut, but withal graceful and effective English.

The average text-book is weak on the subject of Correspond ence, and the pupil is required to write letters about a great variety of matters which have no connection with each other, and which frequently concern things so far beyond the scope of his knowledge and experience that he can not comprehend the supposed situation. The result is that many times he makes no point in his letter, because he does not understand what he is writing about, uses a few worn-out phrases and makes several ludicrous errors. Ask the same pupil a few questions about some business or some line of work with which he is familiar and, omitting the Dear Sir and Yours truly, he may give you, orally, a fairly good business letter.
