whence it flows. In Turkey Lake the water has a clear, almost greenish appear- 

 ance. The measurements of intiow and outflow taken will have no value, because 

 of the swollen condition of the streams at the time they were taken. 



Cedia- Lake (or Clear Lake of the Government Surveys, also "The Lake of 

 the Red Cedars") is a shallow, regular body of water having a more than ordi- 

 narily uniform slope of basin, and in no place exceeding twenty feet in depth. 

 About its shores are wooded hills which in almost every part come very near the 

 shore, the south end excepted. Here there is some marshy land. At the north 

 end the hills reach a height of sixty feet. They are a part of the moraine which 

 separates the Mississippi and St. Lawrence valleys. Within a fourth of a mile 

 from the north end of the lake is a narrow ridge loO feet in length, 30 feet wide 

 and 8 feet high, in appearance very like a railroad embankment, which crosses a 

 narrow hollow and' divides the waters which flow into these two systems. To the 

 north of it is a swamp of perhaps fifty acres in extent, extending to the ridge. 

 On the south side a narrow channel twenty feet in width, choked with grasses, 

 etc., but still with stagnant water in it, starts a few feet from it; further down the 

 soil has waslied in and closed it, except for a narrow stream. The whole appear- 

 ance of the ridge is that it is very recent formation, but I am informed it was 

 there when the white men came. The moraine at the north, the appearance of a 

 wide valley to the southward and the shallowness of the lake make the conclusion 

 almost irresistible that this lake basin has been formed by the washing of the 

 water of the melting glacier which has rested on the north of it, as the water 

 found its way to the Kankakee. The present outlet is by a small stream flowing 

 past the town of Lowell to the southeast into the Kankakee. 



The ice beaches on this lake are larger than those of any other I have 

 noticed. On the north is a ridge of sand, probably formed in this way, 1,000 feet 

 long, 35 feet wide, and about 7 feet high in the highest part. On the east side are 

 two others, but much less conspicuous. The bottom of the lake is generally sand.. 

 Vegetation is less abundant than generally in the shallow lakes in the eastern 

 part of the State. The muskrat is very abundant, building, according to its 

 habit, reed houses in the fall in great numbers at a little distance in the lake. 

 At the northwest side near the end of the great sand ridge was found an Indian 

 mound. This had been opened and a number of skeletons found in it. On top 

 of it grew formerly an oak tree showing almost 200 "growth marks." 



I am under obligations to Rev. Timothy Ball, of Crown Point; Dr. Herbert 

 S. Ball, of Crown Point; Mr. A. D. Fisher, of Indiana University, and the Mo- 

 non Railroad Company for valuable assistance, information, etc. My report of 

 this lake would be very meager indeed had I not received the assistance from the 

 gentlemen at Crown Point.
