POINT. 



Astronomical post 



Dome of Capitol ..- 



N. E. corner of section IG 



Intersection of axes of Capitol and 

 Michigan avenues 



liOngitudo West of 

 Gi'eenwiclj. 



84° 33' 19.G8" 

 84° 33' 23.17" 

 84° 32' 37.3G" 



84° 33' 1G.9S" 



LonKiturlo West of 

 Wasliington.

7° 30' 17.37" 



7° 30' 31.56" 



7° 30' 11.18" 



On the supposition that the longitude of Washington is 77° 03' 05.80" Avest 

 of Greenwich, the hist cohinui in tlic foregoing table was computed. 



This is the longitude of Washington commonly used in all computations, but 

 the most recent determinations of the coast survey make the longitude of Wash- 

 ington 4.05" less than the value given above. 



In accordance with these values Lansing time (dome of capital) is 5h. 38ni. 

 13.54s. behind Greenwich time, Oh. 30m. Ol.lGs. behind Washington time, Gm. 

 01.07s. behind Detroit time (lake survey observatory), 12m. 13.10s. ahead of 

 Chicago time, and 3m. 18.493. behind Ann Arbor time. 



ELEVATION OF THE COLLEGE. 



An arbitrary mark on the iron water table of College Hall, and near the 

 northeast corner, has been taken as a standard bench mark, and is the refer- 

 ence point of all the levels run on tlie College premises. 



Prof. Kedzie, desiring to test the accuracy of elevation of the College as found 

 from the barometer, learned by correspondence with the railroads that the ele- 

 vation of the D., L. & jST. R. E., at its crossing with Michigan avenue was 260 

 feet above the level of Detroit Eiver, and the M. C. R. R. at the same crossing 

 (both roads use one track at this point), was 810 feet avove the level of the sea. 

 The raih'oad at this crossing, as found by actual survey, is 9.13 feet below the 

 bench mark previously described. 



This bench mark then must be 819.13 feet above the level of the sea, and 

 269.13 feet above the water in Detroit River. 



This bench mark by actual survey is 2.35 feet below the top of the lower 

 front step of the Capitol. 



In concluding this report, I wish to call attention to the fact that the success 

 and economy which cliaractcrized the various constructions undertaken by this 

 department, were largely due to the efforts of the Engineer of the Boarding 

 Hall, Mr. Geo. Burdick. For no extra compensation, and no relief from his 

 already arduous duties, except such as could be afforded by student labor, he 

 took the immediate oversight of the construction of tlie dam, laying of the 

 water-pipe between the two halls, zincing tlie boiler room of Williams hall. 

 He also did much mechanical work about the halls that otherwise would have 

 required the services of a costly mechanic.
