To the President and Executive Committee of the Michigan State Agricultural Society : 

 I have the honor to submit the following report of the exhibit of the Machinery 

 Department at the State Fair at Jackson, September 10 to 14, 1888. 



Report of Superintendent. 



Machinery Hall at Jackson, in which most of the entries were exhibited, is a build- 

 ing 50 by 150 feet. The roof is supported by posts which stand in such a way as to give 

 us five aisles lengthwise of the building, and thirteen aisles crosswise. The space free 

 of posts in any particular place was 10 by 11£ feet. The main di'iving shaft for 

 machinery was 2 7-16 inches in diameter, and located in the center of the building 

 lengthwise. It was a matter of some difficulty to arrange machinery exhibits in such 

 a building to the best advantage, and impossible to satisfy the demands of all exhibitors. 

 I finally decided that the exhibits could best be shown if in the south part of the build- 

 ing the center space and side space were reserved for exhibits, with two aisles for 

 spectators, and in the north part of the building, the whole space to be given to exhibits, 

 with the exception of one aisle. The Chairman of the Business Committee very kindly 

 had the building divided in this way. This was quite satisfactory to exhibitors, and 

 would have been perfectly so had there been a second line of shafting on the west side 

 of the building over Division H. 



The arrangement of the building is shown in the accompanying blue print. 



The following exhibits were shown in the building: Division A, sections 1 and 2, 

 E. Dennis & Co. showed a collection of power planers, buzz saws and band saws. Sec- 

 tions 3 and 4, Geo. Wolcott, Jackson, showed several power shapers for working metal, 

 and one lathe in operation. Division B was entirely occupied by the exhibit from the 

 mechanical departments of the Agricultural College. The work shown was manu- 

 factured entirely by the students, and consisted of three lathes for working in wood, 

 shown in operation in section 1. About 75 machine drawings and 100 more of specimens 

 of turning in wood were shown in division 2. One 15-inch engine lathe, one 15-inch 

 turret lathe, one 12-inch engine lathe, one pair of 12-inch surface plates, and about 150 

 specimens of blacksmith-shop work were shown in sections 3 and 4. One 25-horse 

 automatic power engine, one 4-horse power double engine and three 3-horse power 

 engines were shown in operation in sections 5 and 6. 



In Division C, section 3, Dennis & Glover, of Saline, Mich., exhibited an emery 

 grinding machine and a Waid engine model. In section*4 Rodebaugh, Garrison & Co., 

 of Jackson, exhibited several varieties of saw-mill dogs, saw guides and self-oilers, also 

 an interesting model of the first power log turner. Space 5, mill machinery by John 

 Hutchinson Co. Space 2, F.W. Olds, of Munich, Mich., made an exhibit of saw frames. 

 In Division E, sections 1, 2, 3 and 4 were occupied by the Smith Purifier Co., of Jack- 

 son, who made a very instructive and complete exhibit of modern mill machinery. 

 Space 6 was occupied by Wm. Herring, of Allen, Mich., with an exhibition of apple- 

 reducing machinery. The whole of Division D, two sections in Division A, and one 

 section in Division C, were occupied by agricultural implements, under the supervision 

 of Mr. Young, of Paw Paw.
