PALiEONTOLOGICAL BEPORT OF GEOLOGICAL SUKVEY. 551 



of iron, have preserved the impressions of fossil plants in a very good 

 state. The ferns, when present, belong to the largest species. With 

 the Lepidodendron and their fruits, found in great abundance at Wilkes- 

 barre, Carbondale, Minersville, Tamaqua, and Summit Lehigh, the 

 fefns mostly seen in these low veins are Alethopteris Serlii, with its 

 near relative Alethopteris (Pecopteris) lonchitica, and also with Neurop' 

 tens hirsuta and Neuropteris Clarksoni, Lsq'x. The fruits and needles 

 of Lepidodendron, viz : Lepidostrobus and Lepidophittum, are also very 

 abundant in the Mammoth vein of the anthracite, and since we did 

 not find any specimens of these fruits any where else, viz: in any 

 other bed above, their presence may be relied upon as a true character 

 of the lowest beds of the coal basin in general, (p. 8 to 9, MSS.) 



"We have already alluded to the identity of the great Apalachian 

 coal with the anthracite formation, asserting that this identity is espe- 

 cially striking by comparison of the flora of the different strata. 



"The lowest bed of the basin (our coal No. 1, B,) rests on the con- 

 glomerates, and crops out at Summit Portage, where we collected some 

 Lepidodendron and Lepidophillum; at Johnstown, where the black 

 slates of the roof are charged with Lepidostrobus, especially with 

 Lepidostrobus brevifolius, Lsq'x., and also with Lepidodendron, at 

 Cuyahoga Falls, Ohio, where the shales abound with the same plants, 

 and also with Peopteris lonchitica, and some Sigillaria. There is also 

 there plenty of fruits — Curdiocarpon, Carpolithes — as at the low vein 

 of Trevorton, Penn. The last place where we had opportunity to ex- 

 amine this vein, so rich in fine fossil vegetables, is on the great Ka- 

 nawha river, three miles above Charlestown, where we found the roof 

 shales covered with Alethopteris Serlii, and with some fine Lepidoden- 

 dron, and Lepidostrobus in abundance. From this we shall necessari- 

 ly be permitted to draw this conclusion: that this vein of coal, pre- 

 serving so well it characteristic fossil plants, and at so great distances, 

 was formed at the same time, and under the same circumstances, as 

 well in the whole extent of the great Apalachian coal as in the anthra- 

 cite coal-fields." (Pages 10, 11, MSS.) 



This is nearly a repetition of what we have said about the lowest 

 bed of coal, viz: No. l,B,of the western coal-fields of Kentucky; and 

 for this basin, also, we must necessarily draw the same conclusions as 

 above. 



The correspondence of No. 2 coal with cannel coal C, of Pennsyl- 

 nia, of our No. 4 with the Pomeroy vein of Ohio, and with the Gates 

 and Salem veins of ,the anthracite, at Pottsville, as also the relation 

 of No. 6 ccal with the Steiger's bed of Athens, Ohio, have been already 

 and sufficiently pointed out.
