region. 



[The intervals indicated are those between the horizons in whoso colnnins tlie numbers occur.] 



It is ot" interest, however, to note a few of tlie \ariations. sucii as 

 that in the interval between the Buck Mountain coal and Lykens coal 

 No, 1, which at Colket is 103 feet; at Good Sprino-. -t miles Mest, 

 210 feet, while at New Lincoln, farther south, l)ut in reality al)()ut 2^ 

 miles from either (xood Spring- or Colket, it is 250 feet. Similarly, the 

 inter\al between the Lykens coals 5 and ♦>, which is but -tT or 4S feet 

 in tlie New Lincoln and Lincoln mines, measures 75 feet at Kalmia, 

 with which direct underground connection is mad<'. wliilc the same 

 thivkness is observed at Williamstown. 



In passino- from the subject of the variability of the terranes of the 

 Pottsville formation, it should be ob.served tliat tlic succeeding Coal 

 ^Measures also, especially in the Panther Creek r)asin and the regions 

 west of Potts\ilie. show the continuation of conglomerate sedimenta- 

 tion in enormous (jiuuititics. though the formation is generally softer
