27 the sections. The students are practiced in so handling their instruments as to reduce to a minimum the errors due to con- struction and wear of bearing surfaces. Each party consists of a transit man, two chain men, and a pole man, the transit man being in charge. The work consists of determinations of distances from measured bases, and heights of inaccessible objectsg check readings of angles, and means of repeated angles to insure careful manipulation 3 extended meanders to illustrate methods of surmounting difficulties: complete sur- veys of two or more farms, with location of buildings, intersect- ing fences and roads. In these surveys, magnetic bearings, true bearings, azimuth from assumed meridian, and deviation angles are used. If the error of survey exceeds Mlm the work is not accepted. A simple triangulation of a river, a lake, or harbor is also given. In the Practice of Leveling, the adjustments of instruments and sources of error are learned. The Boston, New York, and Philadelphia rods are used. A working party consists of a leveler, a rodman, and two or more chainmen, as the character of the work may require. Difference of level of two points is determined 3 section levels for profile are run 3 determinations of overflow contours for river and mill work are requiredg grade contours for railroad, and contours for topography are taken. The precautions necessary to secure desirable results are dwelt upon daily. Throughout the Sophomore and Junior years, at least two weeks of each summer vacation are devoted to work in the field. Upon completing the Course in Civil Engineering the student, in addition to his theoretical knowledge, should possess a thorough mastery of all the instruments which he will be called upon to use in his profession, and at the same time should have acquired the elements of a liberal education, sanity of judgment, and the ability successfully to undertake and control engineering enterprise of magnitude.

Q!! flf 'ffl llil The Course of Civil Engineering is intended to meet the requirements of students desiring to enter the profession of civil engineer, and it aims to equip the student with the theoretical and practical training requisite for successful independent work. The instruction demands much practice in the field and the drafting room, and a thorough mastery of all the instruments required for use in the profession. The general principles underlying engineering science are surveyed by means of lectures and recitations. The Field Work commences with the steel tape, pins, and ranging poles. Chains ot' former patterns are exhibited and discussed, and dynamometer and thermometer attachments are considered. A field party consists of four members, to each of whom special duties are assigned, one being director of the party. This elementary practice is designed to familiar- ize the student with the instruments, and to demonstrate their range and their limitations. Only methods which are of prac- tical utility are used. Some of these applications are :-check measurements of distances, to insure skillful manipulation and avoidance of sources of errorg erection of perpendiculars at given points on a line, and running perpendiculars from given points to located linesg running of parallelsg measurements of anglesg laying out curves 5 and survey of area by distances and intersections. Students next enter upon the practice of surveying with compass and transit. The instruments are thoroughly mas- tered, and all their adjustments perfected by the members of

Special preparation is afforded those who in after life may be concerned with electric railways, with the telephone, with electro-metallurgy, with electric lighting, generation, trans- mission, and the utilization of electric power. In shaping the worlc the aim has been to educate the student in accurate observation, in a truthful recording of his observations, in the drawing of correct inferences, and in the embodiment of his work in concise English, and also to impart such a knowledge of electrical engineering practice as to enable him to enterany of its branches, having acquired sufficient skill in the manipula tion of instruments and machines to fit him to carry on inde- pendently and with confidence the tests and measurements liable to occur in practice. Numerous problems in construc- tive engineering and designing impress upon him the import- ance of details, and in these problems working drawings to scale are required whenever necessary. Each candidate for the degree of Electrical Engineer is furthermore required to carry out an original investigation and to present a thesis embodying its results-this kind of work seeming best adapted to develop the individual resources of the student and to give him confidence in the results obtained. For the Freshman year there are prescribed courses in English, in trigonometry, in analytical geometry, in French or German, in mechanics, in shop-work, in general chemistry, and in mechanical drawing.
