thoroughly understand a problem, a complete demonstration, showing how and why each step is taken in the solution of a problem. It is somewhat similar to the blackboard work in the college class-room, but has this advantage: the instructor's demonstration may be kept. and referred to at any time, whereas the blackboard work in the classroom is soon erased.

Instruction Papers. The Instruction Papers have been prepared especially for correspondence work by engineers and teachers who, through long practical experience and training, are in a position to know the needs of correspondence students. The papers are frequently revised to keep them up-to-date in the best and latest engineering practice. Each subject is taken up from the beginning and thorough explanations are given in at

clear, concise manner as the student progresses. They average about eighty pages each, are neatly bound, and form a valuable reference work for the student after the completion of his course.

If,

Special Examinations. Mathematics is the basis of all mechanical study; hence Arithmetic is given first to all students. however, a student already proficient in Mathematics does not care to take up the preliminary work in Arithmetic, he will be given, upon application, a special examination. This concession does not apply to other subjects, as a rule, and diplomas are awarded only to those who have carefully covered all of the course, except Arithmetic. All students, however, are strongly advised to work out all the examinations in Arithmetic.

System of Marking. In marking the student's work, the School has adopted the system used in many leading colleges, grading each paper "Perfect," "Excellent," "Good," or "Fair." These grades correspond to the following percentages: "Perfect," 100%; "Excellent," 90 to 100%; "Good," 80 to 90%; "Fair," 75 to 80%. The percentages obtained by the student in each subject are kept at the School, and the student's average per cent is given to him upon. graduation.

Final Examination. As a rule, the student is required to take a final examination before being awarded a Diploma or Certificate of

Proficiency. If his work, however, has been of high character throughout his course, no final examination is required.

Diplomas and Certificates of Proficiency. After having completed his course, and having satisfactorily passed all the examinations, the student is awarded a Diploma, certifying to these facts. The general character of the student's work throughout the whole course is indicated in the Diploma, which states that he has graduated with "Credit," with "High Credit," or with "Highest Credit."

Employment Department. This department aids students and graduates in securing positions for which their training has fitted them. It also co-operates with employers, furnishing reliable, welltrained men. The School frequently receives requests from manufacturers and engineering firms in all parts of the country for welltrained men from among its students and graduates, and the number

of these requests exceeds the School's list of available graduates and advanced students. The School keeps in touch with manufacturing interests everywhere, and is thus able to lay out courses adapted to the student's needs. Graduates and advanced students have almost invariably obtained good positions and in the section of the country desired. The School will always, upon request, advise any employer of the progress and educational capabilities of a student, or render any service to its students within its power.

Special Inquiry Department. This department is one of the sources from which a student can derive the greatest benefit. It offers a student the privilege of submitting to the Instruction Staff practical engineering questions connected with his daily work. Questions are answered in a simple, concise and practical manner and the explanation is accompanied by diagrams when necessary. Thus the School co-operates with the ambitious student in making his daily work most valuable to his employer and to himself.

Library Department. To facilitate the student's progress and to afford him a larger opportunity for reading, study and reference in subjects allied to his own course, the School has compiled a library of ten volumes, entitled "Reference Library Modern Engineering Practice." This Library is a comprehensive reference work on prac

tical methods for the Machine Shop, Engine Room, Power House, Electrical Light Station, Boiler Shop, Drafting Room, Foundry, Pattern Room, Blacksmith Shop, Round House, Plumbing Shop and Factory. For the busy mechanic, this Library is of great value, and supplies in a concise form the information needed to meet the hundred and one practical problems arising

in every-day work.

Evening and Summer Classes have been inaugurated at the Armour Institute of Technology for students in and about Chicago; these offer rare opportunity for shop and laboratory practice. The evening classes begin in the fall and continue. throughout the winter and spring months; the summer classes begin in the latter part of June and continue for six weeks.

Time Limit. A Student ordinarily completes his course in from eighteen months to two years, according to his aptitude, previous training and time for study. Obstacles, however, sometimes arise which impede a student's progress and for this reason five years' time is allowed in which to complete any course.

What a Scholarship Includes. The tuition entitles the student to instruction until his course is completed, provided this is accomplished within five years from date of enrollment. All textbooks and supplies are furnished free except drawing instruments and blank paper. The School pays postage on all letters and supplies sent by mail to the student. There is, however, an additional fee for foreign postage.

College Preparatory Work. There are a great many people who would gladly attend College if four years' High School work were not required for entrance to such institutions.

It was to meet the needs of such persons that the College Preparatory work was inaugurated. Students satisfactorily completing the course as outlined on Page 162 of this Catalogue will be admitted to the College of Engineering of Armour Institute of Technology without further examination in the studies pursued.

Patent Department. The School has made arrangements with an expert patent attorney who will advise all students regarding inventions which they wish to patent. The only expense will be the actual cost of making search, etc. Full description with sketches should be submitted.
