The coals in this section are at 48, 300, 597, 629, 669, 681, 771, 885, 

 930, 1,053, and 1,128 feet below the Buck Mountain coal bed. Mr White 

 would draw the line for base of Pottsville at about 20 feet below number 

 25, thus giving somewhat more than 1,150 feet for the thickness. The 

 numbered beds have been mined. Coals numbers 2 and 3 may be re- 

 garded as one bed, for at New Lincoln colliery they are separated by a 

 mere parting. The division between Upper and Lower Pottsville may 

 be made at a few feet below Lykens Valley number 3, for above that the 

 rocks are more massive than below. Here, too, Mr White finds reason 

 for a paleontological separation. He visited some of the old workings 

 at the extreme western end of the southern prong, which were described 

 by Mr Taylor. Though the slates on the dumps were much disinte- 

 grated, he was able to recognize the plant remains, and thereby to deter- 

 mine that the whole of the Pottsville is represented there. 



The relations in the northern prong are quite similar. A series of bor- 

 ings near the western extremity showed eleven streaks of coal, 1 inch to 

 3 feet 2 inches, but two of these become 5 and 9 feet thick within a short 

 distan'ce. In the Lykens Valley region, farther east, the beds of the 

 upper division above numbers 2 and 3 are wanting, those beds, united 

 into about 5 feet of shale and coal, being separated by somewhat more 

 than 600 feet of mostly conglomerate from the Buck Mountain horizon 

 above. The Whites coal bed, regarded as number 4, is at 825 feet, and 

 number 5 is at 1,056 feet, while number 6 and the little coal below are 

 at 1,131 and 1,175 respectively. The anomalous interval is that of the 

 Whites bed, which is more than 100 feet higher in the column than in
