" suggests very strongl}' tlie Laekaflaxon conglomerate of Pennsyl- 

 vania";' while Professor Claypole stated that "the two conglomerates, 

 the Allegrippus and the Laekawaxen, .... figure conspicuously in the 

 outcrops of the Chemung from Virginia to Kew York." ' Professor 

 Ijcsley, however, called attention to the fact that the Eeports for Blair, 

 Center, Clinton, Lycoming, Union, Snyder, Mifflin, and Juniata counties 

 situated in the lino of strike of these formations to the northeast of 

 Bedford, Fulton, and Huntingdon counties make no mention of these 

 conglomerates. ° He also considered the one described by Dr. I. C. White 

 at Roaring Eun, Columbia County, intermediate in location between those 

 of the southern counties and the Laekawaxen conglomerate of Pike 

 Count}'', which Dr. White provisionally correlated with the latter con- 

 glomerate,* and concluded that " Considering the solitary apparition of 

 this Eocky [Eoaring] Eun conglomerate, as we may call it, and the large 

 number of fish beds known to exist in Chemung and Catskill series, it 

 seems to me a little hazardous to adopt unhesitatingly its identity with 

 other fish-bed conglomerates in distant comities of the state. We must 

 leave to future explorers the task of proving or disproving such facts." ° 

 It appears to the writer that there is as yet insufficient evidence to 

 warrant the correlation of Stevenson's upper conglomerate of Bedford, 

 Fulton, and Huntingdon counties with the Laekawaxen conglomerate of 

 northeastern Pennsylvania. This conclusion appears to be warranted 

 when we consider the rather limited extent, in general, of deposits of 

 this character and especially when it is noted that Dr. White stated that 

 many of the pebbles of the Laekawaxen conglomerate are angular and 

 exhibit " little evidence of water wear " ° while the pebbles of Stevenson's 

 upper conglomerate he described as " generally fiat." '
