south-east from Duck Harbor lake, on the land of Mr. Rut- 

 ledge, where the following succession occurs : (Fig. 45.) 



It u fledge seel ion. 



1. Honesdale Upper sandstone, massive, white, 50' 



2. Red sandstone, 35' 



3. Honesdale Lower sandstone, 20' 



105' 



The base of the Honesdale Lower sandslone conies loll)' 

 A. T. The rock is brownish gray on fresh fracture, but on 

 its weathered surface is very whitish, with occasional small 

 black specks ; the whitish color being due to a removal of 

 the iron by atmospheric action. 



No. 2 is the same peculiar red sandy material that we con- 

 stantly rind at this horizon ; it is almost too fine in grain to 

 be called a sandstone, and yet it is so gritty and hard that 

 by no stretch of fancy could it be termed a shale. ■ 



No. 1 is very massive, and seems divided near its cen- 

 ter by a thin band of shale into two beds ; this is not seen 

 at the locality of the section, but on the opposite side of the 

 valley. Here the whole series is exposed in a steep bluff. 



Where the county road crosses the outlet of Duck Harbor 

 lake, the stream makes a fall of 20', over a massive gray sand- 

 stone, whose top is 1315' A. T. 



The Honesdale group is seen five miles south from Rut- 

 ledge's extending along both sides of the south branch of 

 Calkin's run ; the upper sandslone having an elevation of 

 1480' A. T. Far up in the hills above we see another 

 massive sandstone with an impure limestone at its base 5' 

 thick ; this is at an elevation of 1615' A. T., 135' above the 

 base of the Honesdale Upper sandslone, (approximately) 

 200' above the base of the lower o?z£, and is therefore the 

 Cherry Midge limeslone ; it is seen in large black bowlders 

 scattered over the hill tops in every direction ; on fresh frac- 

 ture this rock is seen to consist of a conglomerate mass of 

 pieces of shale, pebbles of sandslone, and immense quanti- 

 ties of what appears to be fish bones, very much broken and 

 worn, all cemented into a matrix of calcareo-siliceous ma- 

 terial, of which probably 20 to 30 per cent, is calcium car- 

 bonate.
