4 JS^utice of Snake Hill and Saratoga Lake, c^-c. 



quite to the base of the mountain, the distance of six or 

 leven miles further ; but, on the elevated ridge, to the 

 rorth-east, which extends as far north as the Fish-creek, 

 a distance of five or six miles, the stratification seems to 

 correspond with that of Snake Hill, consisting of alterna- 

 ting strata of graywacke and argillaceous slate, the direc- 

 tion of which is either vertical, or inclining to the south- 

 east, evincing a derangement, the effect of a process sim- 

 ilar to that which elevated those 1 have already described. 



The utmost extent, then, of the operation of the power 

 could not have exceeded the distance of three or four 

 miles from east to west, and, in the direction from north- 

 west to south-east, it might have been thirteen miles, ad- 

 mitting that it commenced at the termination of the prim- 

 itive mountains : but why may not the effects, above des- 

 cribed, he imputed to the continuation of the power which 

 elevated the primitive rocks themselves ? I have no incli- 

 nation to discuss this question ; 1 have merely stated the 

 iacts, together with such leflections as must, unavoidablv, 

 follow from a careful examination of the spot. 

 Yours very sincorcly,

P. S. 1 take the liberty to forward you a specimen ot 

 oo/?7e, an extensive formation of which has lately been dis- 

 covered in this vicinity, presuming it would be peculiarly 

 interesting to you, as hitherto, it has been supposed not to 

 occur in situ in North America, unless pcrhapsat the locahty 

 on the Ohio, mentioned by Mr. Jessup. I shall endeavour 

 to furnish you with a particular account* of it for your next 

 No. of the Journal of Science. J. M. S.
