ibus albis which 1 fur the present call Galium 

 Mollugo, though I think I am wrong in the 

 name : I never seen this plant before, excepting 

 in dryed specimens in the collection of Dr. Bar- 

 ton. In going up the river we came to a bed of 

 of coal, which points out close to the edge of the 

 water. 



Mr. Hart observed, that there was an open 

 Coal pit at about 2. m. from there, & if I choosed 

 we would go to it ; this was as welcome an offer 

 to me as could be. We crossed Millcreek & turn- 

 ed off from the river. — In this wa.k I found Con- 

 volvulus spithamaeus— Asclepias quadrifolia & 

 Gratiola officinalis, in full flower. In crossing- 

 Mill creek <fe coming up the hill by the saw mill, 

 I observed on the slaty gneis a good many signs 

 of copper, being in this nighborhood ; the bloom 

 of vertigriss showed itself in several specimens of 

 stone & altogether the stone seemed to be of the 

 same kind as that near Mr. Hughes' Iron Works 

 at An tie tarn in which place copper has been 

 found. We at last arrived at the Coal mine, the 

 sight of which, I admired more than I could have 

 expected ; It lays in draught or hollow, where one 

 of the faces of the stratum of coal has been opened, 

 by a little stream of water running with great 

 swiftness alongside of it, & down a deep hollow 

 by a kind of cascade. The face of this hill or 

 stratum of coal is about 26 feet, from the sur- 

 face of the ground, to the level of the little run ; 

 the coal beginns about 3 feet below the surface 

 & its stratum goes below the level of the run ; 

 so that it may be judged to be a bed of coal more 

 than 30 feet thick. A: probably more strata below
