102 G 5 . REPORT OF PROGRESS. I. C. WHITE. 



boro', a sandstone 150' above the base of the New Milford 

 group has been extensively quarried and nsed in building 

 the great viaduct across the Starrucca valley on the N. Y., 

 L. E. & W. H.R. It is a greenish gray rock, tolerably 

 hard, and seems quite durable. 



In passing up Starrucca creek i'rom Stevens' Point, the 

 outcrop of the New Milford Sandstone group is almost 

 constantly seen, the massive members jutting out of the 

 hills in lines of vertical cliffs. I was informed that near 

 Webster's mill a seam of coal 1" to 2" thick is seen in one of 

 these sandstones. 



Along the Susquehanna in this township the Drift is very 

 thickly piled in immense heaps, but no crystalline bowlders 

 were seen in any of the material. 



9. Thompson, in Susquelianna county. 



This is a small area lying directly south from Harmony, 

 and like it, adjoins the Wayne county line. 



It is drained principally by Starrucca creek, the left branch 

 of which takes its rise in the southern, and central portions 

 of the township. 



The rocks belong to the middle portion of the Cats'/till 

 series. 



The surface is very rough, and huge cliffs of sandstone 

 are seen in almost every hill, while large bowlders cover the 

 ground almost everywhere. 



Just west from Starrucca Depot, the following section was 

 seen in descending the steep hill to the Jefferson Branch R.
