DEPARTMENT REPORTS. 69 



vacancy caused by tilie resignation of Mr. Hewlett. Mr. Hineline, ma- 

 chinist, was released in order to decrease the salary budget of the depart- 

 ment. The release of the machinist necessitated a decrease in the amount 

 of repair work done in the department shops. Such repairs as Avere abso- 

 lutely necessary were made by the instructional staff and student help. 



The Fann Mechanics Department was again given assistance in the 

 Truck and Tractor short course. Instruction was given by Mr. Sangster 

 in the forge shop, and the equipmejit of the department was used in the 

 courses in Ignition and Lighting, Truck Engines, and Carburetion. 



In the summer school, instruction was given in several machine shop 

 courses, sixteen men having been registered in this work. Mr. Wright 

 had charge of the courses. 



During the year a switch-board was added to the turbo-generator in the 

 Engineering Laboratory, and the board was so wired that connection 

 could be made to the power and lighting circuit of the Engineering Build- 

 ing. On dark days this equii^meut Avas used to decrease the load on the 

 main poAver station. Several pieces of equipment were loaned to the 

 department for test purposes, \dz:, a gasoline engine driven pumping 

 outfit, by the Novo Engine Co., and a water brake dynamometei* for 

 testing automobile engines by the Reo Motor Car Oo. Through the influ- 

 ence of one of our students, Mr. R. E. Dunlap, the Globe Mfg Co., of 

 Battle Creek, presented the department with a small air compressor, 

 such as is used in garages. 



Considerable testing of spokes and wheels wais done during the year 

 for the Motor Wheel Corporation, and some miscellaneous tests were run 

 for the City of Lansing, and various cement block concern's. 



During the year frequent shop visits were made to the Novo Engine 

 Co., the Ryan-Bohn Foundry, the Atlas Drop Forge Co., and the Reo 

 MotoT Car Co., and appreciation is expressed for the eourtesles shown 

 on tliese visits. 



I also wish to express my appreciation of the courtesies shown by the 

 Novo Engine Co., the New-Way Engine Co., and the Pruddeu Wheel Co., 

 during the investigations conducted by seniors as part of their technical 

 work. 



With the exception of the switch-board, the needs expressed last year 

 are istill present and I earnestly hope that the coming year will relieve 

 this condition. 



The optional courses of the senior year were divided as folloAvs : Steam 

 Engineering — 2 men. Industrial Engineering — 18 men. 



I wish to express my appreciation of the work of the various members 

 of the department during the past A^ear, 



The teaching schedule for the year is shown in the tables that follow. 



Respectfully submitted, 



H. B. DIRKS, 

 Professor of Meclianical Engineering.
