Laurens. 



The township of Laurens lies directly south of New Lisbon, except the 

 northeastern corner, which is south of Hartwick, the township adjoining New

 1 nooks, the largest being Keyes brook in the northeastern corner of the town- 

 ship. The ridge on the western side of Otego creek is not nearly as steep 

 as the one on the eastern side, and it is broken by a number of brooks and 

 creeks of fair size, with corresponding valleys. 



XXIV C\ Slightly northeast of the village of Mt. Vision, in the north- 

 eastern corner of the township, is a steep hill, which rises 375 feet above the 

 Otego creek, known as Mt. Vision. The hill lies between the valleys of 

 Otego creek and Keyes brook, the latter being at its greatest distance only a 

 little more than one and one-half miles east of Otego creek. The hill has, of 

 course, been formed by the erosion of the streams on its eastern and western 

 sides, w ith its steeper Hank toward the larger stream and tapering to a point 

 opposite the junction of the two streams. On the hillside, one hundred feet 

 above the creek, are prominent ledges of coarse, arenaceous shales. They are
