Vacation J o u r n a l s and Memoirs.

31

Journals of Travel are required to be kept during the summer vacations. Entries should be made as often as once a week, and consist of notices of manufactories, especially of their peculiar mechanical methods and machines. Dimensions of large or important machinery, such as stationary engines of water works, blowing or hoisting engines, and machinery in use in mining or other operations, may form a part of the record. The Journals of the first Vacation are to be read and discussed in connection with the class in Designing and Shop Practice, and those of the second in connection with the class in Cinematics and Principles of Mechanism. They should be illustrated by sketches reproduced upon the blackboard. Reports or memoirs upon visits and observations of the third vacation, will be required instead of journals, to be read in the class in Machine Drawing during the middle term of the fourth year. These reports should be made upon rare and interesting mechanical operations or machinery, such as making gas pipe, spinning zinc, copper and brass ware, manufacturing saws, etc. They will be placed in the Library of the School, and should be illustrated by ample sketches and drawings. APPARATUS. This School is provided with plates and a cabinet of models for illustrating mechanical movements and elementary combinations of mechanism. This collection is rapidly increasing by our own manufacture, and by purchase from abroad. A supply of Riggs' models has lately been added, and more are ordered from the celebrated model manufactury of J. Schroeder of Darmstadt, Germany. About two hundred valuable models have lately been received from the U. S. Patent Office. This plan shows the arrangeMechanical Laboratory. ment of the Mechanical Laboratory. The bottom and left-hand side of the plan correspond to the two faces of the Mechanical Building, shown in perspective on page 17. In the Boiler and Furnace Room, T is a Root's Sectional Safety Boiler of 33 horse-power, which supplies steam for the enDRAUGHTING gine, and for warming the buildAND CLASS HKOOM ing. The Forge and Furnace, U U, are in this room, and also a moulder's bench with sand and the appliances for making brass, iron, and other castings. At Z are the Pumps, and Stilwell Heater and Lime Extractor for supplying the boiler with water. In the Machine Shop, A is the Engine, of 16 nominal horse-power, but capable of working to 30. It is regulated by a variable cut-off of new design and simple construction, by Professor Robinson. It was made by the students of the University. A Richard's Indicator of the most approved construction is fitted to the cylinder. The main line of shafting is cold-rolled iron, 72 feet long, and furnished with the best iron pulleys
