[Hendry. 



The Librarian communicated an extract from a letter of 

 Mr. W. A. Hendry, of the Crown Land Office, at Halifax, 

 respecting the discovery of a large bed of coal among the lean 

 beds of the Joggins and Albert Mine regions : 



" No new discoveries have been made, since you were here, except 

 perhaps at the Spring Hill, which I visited two months ago. You 

 recollect its position on the map. A discovery has been made of a 

 seam of coal, said to be 16 feet 

 thick. I myself measured nearly 14 

 feet; but 16 and 18 feet has been 

 currently reported as the thickness 

 of the great coal-seam of Spring Hill. 

 The bed, with thin clay partings, 

 gives from 12 to 14 feet of good 

 bituminous coal. I am well ac- 

 quainted with the gentlemen who 

 are geologists there, Messrs. Mills 

 & Sherer." It is well known that 

 of more than a hundred coal-beds 

 outcropping among these measures on 

 the coast of the Joggins, not one is 

 much more than 4 feet. It is no- 

 ticeable that this large increase in 

 the size of one of these beds, that at Spring Hill, takes place at 

 the head of a synclinal axis, towards the east, as shown in the 

 diagram. 



The following summary of the rocks passed through in an 

 old salt boring in Clearfield County, Pennsylvania, was com- 

 municated by the Librai-ian, from a letter from Mr. John M. 

 Hale, of Reading. The Librarian remarked, in offering the 

 section, that, it was one of the most useful duties of learned 

 Societies to obtain, and place on record, the too easily lost or 

 destroyed results of the labors of the past. 



" Some twenty-five years since, a company bored for Salt Water, 

 at the junction of the Beaver Dam and Eastern branches of the 

 Clearfield Creek, where a natural salt lick existed, and employed 

 Mr. S. C Wilson to superintend the operations ; and to him I am 

 indebted for a copy of his notes, a synopsis of which I thought 

 might be interesting to you, if you have not seen them.
