Excerpt from Locomotive Boilers, Steam Cylinders and Valve Gears, Locomotive Management, Breakdowns, Compound Locomotives The only requirement for admission to any of the courses offered by the International Correspondence Schools is that the applicant shall be able to read the English language and to write it sufficiently well to make his written answers to the questions asked him intelligible. Each course is complete in itself, and no textbooks are required other than those prepared by the Schools for the particular course selected. The students themselves are from every class, trade, and profession and from every country; they are, almost without exception, busily engaged in some vocation, and can spare but little time for study, and that usually outside of their regular working hours. The information desired is such as can be immediately applied in practice, so that the student may be enabled to ex hange his present vocation for a more congenial one or to rise to a higher level in the one he now pursues. Furthermore, they wish to obtain a good working knowledge of the subjects treated, in the shortest time and in the most direct manner possible.
