6 Granger on Xanesville Slate. 



this with the stalk and leaves — stalk two feet, leaves about 

 eight inches. 



No. 7 and 8, impressions are from the same, but the stone 

 contains more sand. 



No. 9, specimen of sand stone from the same bed — simi- 

 lar impressions are found in bituminous and argillaceous 

 slate, in the same bed in great abundance. 



The next stratum is sand stone varying in thickness from 

 five to fifty feet in different places. The solid parts of the 

 rock contain throughout, pieces of carbonized wood — be- 

 tween the layers, the wood is more frequently bituminized, 

 and changed to stone-coal. Trunks and branches of trees 

 petrified are often found, the bark generally changed to stone- 

 coal. In part the wood seems in these cases to have per- 

 ished, leaving a mould w^hich has been filled up with sand. 



C. No. i, 2, 3, 4 and 5 — the drawings are from specir:::ens 

 in this stratum. 



No. 1 must be the same as A. No. 1. They all resemble 

 drawings by the Rev. H. Steinhauer of Fossil Riliquia found 

 in the coal strata of England. 



No 4 is a branch about four inches in diameter a little flat- 

 tened. Above this sand stratum for many feet, lies soft ar- 

 gillaceous slate without impressions. 



D. No. 1 and 2 — specimens rest upon this and form the 

 floor of a coal stratum. 



No 1, was found in length ten feet, and in breadth four 

 feet — impression on the under side. It is doubtless the 

 same as No. 3 in the sand stone. E. Coal.- — The stratum 

 from one to five feet thick. In this vicinity but one stratum 

 is found above the river, another much thicker is found by 

 boring from 15 to 20 feet below the bed of the river. 



F. No. 1 and 2 — (drawing,) three specimens from the 

 roof of a coal bed in one place. In another, small leaves 

 and apparently flowers in the greatest abundance are found. 



G. 1, was found a few feet above the coal, a layer of sand 

 stone intervening. 



Above this, and sometimes resting on the coal, is a stra- 

 tum from two to four feet of shell hme stone — from hence 

 to the tops of the hills is either clay, slate, or sand stone. 



I can only add that these impressions afford a considera- 

 ble variety, and are found in great abundance. 



I am satisfied they are mostly of a tropical growth. It 

 would be gratifying to us to be informed o^ the species of
