48 J. J. STEVENSON — CARBONIFEROUS OF APPALACHIAN BASIN 



In the most southerly basins a bed known as the "Alpha," and some- 

 times of workable thickness, is present at 83 feet below the Buck Moun- 

 tain. In the next basins north borings near Beaver meadow found coal 

 at 27 to 38, 89, and 148 feet, while one at Beaver meadow found no coal 

 in 235 feet. At Honey brook, 6 or 7 miles west, thin streaks were found 

 at 16 and 56 feet ; but at a little distance northwest another boring 

 found only the Alpha, about 100 feet and 6 feet thick. In the Hazleton 

 basin there seem to be no coals at both ends of the basin, though at 

 Hazleton the Alpha is present at 157 feet, and near Stockton two thin 

 streaks are present in the upper 50 feet. No coals appear in any of the 

 Green Mountain sections, but Mr Smith states that the Alpha, too thin 

 to be mined, has been found in several shafts. 



At the eastern extremity of the Black Creek basin, where the Potts- 

 ville is about 300 feet thick, no coal is present in the upper half ; but 

 borings near Jeddo found streaks at 28 and 85 feet, while one at a little 

 way south passed through the whole formation without finding a trace. 

 Near Harleigh, at the western extremity of the basin, one boring shows 

 streaks at 72 and 160. Another finds them at 24, 60, 77, and 120. 

 Northward, near Tomhicken, in the next basin, coal is found in several 

 borings at 53, 65, 72, 76, and 100 feet, but all are regarded as belonging 

 to one bed. Such variations are much less than those in the intervals 

 between the " splits " of the Mammoth bed within this area, which have 

 been proved up by continuous workings. Westward beyond Tomhicken, 

 in this as well as the little McCauley basins, the Pottsville coals are 

 practically unrepresented, having been found only near Gowen, where 

 are two streaks at 45 and 90 feet. 



Northward, in the eastern portion of Little Black Creek basin, near 

 Hollywood, the only coal is a thin bed at 84 feet ; but 2 miles farther 

 east streaks are reported at 68, 93, and 107 feet ; 6 miles farther east 

 one boring finds no coal in 190 feet, while another gives 1 and 3 feet at 

 24 and 75 feet. In the Upper Lehigh the most northerly basin, where 

 the Pottsville is but 165 feet thick, two coals are reported, the upper at 

 17 to 35 feet, from 15 to 42 inches thick, and the other, the Alpha, at 98 

 feet and 52 inches thick. The persistent horizon in this field is that of 

 the Alpha, varying from 60 to 150 feet below the Buck Mountain. Above 

 it are two others, which in many places show thin streaks of coal, but 

 the lower streak may be only a split from the Alpha. 



In the Northern field one finds at some localities a bed known as coal 

 bed "A," very near the middle of the Pottsville. Its distribution is 

 uncertain. The bed is present in the southern district of this field, 

 where its thickness is from 1 inch to 3 feet ; but it appears to be absent 

 from most of the other districts, though traces of it are shown near
