zon of Lykens coal No. 4, are nevertheless strongly suggestive of that 

 level. Thev are certainly from the Lower Lykens division.

The geographic position of this drift is shown in mine sheet xxvi, 

 Pt III of the Anthracite Atlas; and a cross section of the mountain 

 is included in cross-section sheet xxi, Pt. VI of the Atlas.^ 



D On the south side of the crest of Short Mountain, but a short 

 distance to the west of the ^' north vein drift," is located Kugler^s drift 

 (Station 30, PI. CLXXX), opened in 18'24. The positions of both 

 Kuoler's drift and Young s drift, the latter being a little to the west, 

 are'shown on mine sheet xxvi. In his report on the Stony Creek coal 

 area Dr Tavlor reports the presence of a good coal in the former, 

 reachino- a maximum thickness of 4 feet, its horizon being 25 fe^t 

 below that of the coal at Young\s drift, while a smaller bed, the ' lit- 

 tle vein " is said to have l)een discovered 20 feet lower than Kugler s 

 Although the shales from Kugler\s drift are far decayed, they still 

 reveal the presence of —

Neuropteris Pocahontas var. pentias. 1 



Although these species are insufficient in themselves to form the 

 basis of an attempt at a precise correlation, their entire agreement 

 with the flora of the region of Lykens coals Nos. 5 and H, for which 

 I have tentatively suggested the term Mariopteris eremopUroides zone, 

 will at once be recalled. Such a tentative reference carries more 

 weioht than mere suggestion, when the stratigraphic intervals of the 

 neighboring coals are taken into account. It seems, indeed, tar from 

 improbable that, if the measurements reported from these coa drifts 

 are to be relied upon, the 51-inch coal in young\s drift, which is 2o 

 feet above Kugler's, may represent Lykens coal No. 5, the Kugler s 

 drift being in Lvkens coal No. 6, while the "little vem, 20 feet below, 

 mio-ht represent the '" zero" coal of the Wiconisco Basin. It appears 

 tha't in this region of Short Mountain three coals of the Lower Lykens 

 division are present, two of which may attain a workable thickness, 

 although the attitude of the beds near the axis of the syncline prob- 

 ablv unfits them for profitable exploitation. 



E A small collection of fossil plants was obtained from the most west- 

 erly of the shafts shown on the immediate crest of the mountain on 

 mine sheet xxvi of the Anthracite Atlas (Station 31, PL CLXXX). 

 It contains the following species: 



Whittleseya Canipl)elU. 

 Trigonocarpuni auipulla^fornie. 

 Trioionocarinnn Helente. 



Mariopteris eremopteroides? 

 Neuropteris Pocahontas var. pentias 

 Lepidophylluni quinnimontanuni?
