 distance and abide the result, did not appear in the transaction. 

 The cr}' was raised, Let us have the Final Report, whatever it 

 is, and have done with it ! let us see what we have paid a hun- 

 dred thousand dollars for, at all events. 



On the 12th of April, 1851, a resolution passed the Legislature 

 by a vote of 49 to 42, appropriating $32,000 to the revision and 

 publication of the Final Report of the survey. Excepting one 

 or two who were entrusted with the secret, the members were 

 unaware that additional surveying was in question. Mr. Rogers 

 however, immediately took the field, assisted by Mr. Sheafer, Mr. 

 Desor, jSIr. Lesquereux, and myself. Mr. Sheafer brought to the 

 work his long experience aud thorough acquaintance Avith the 

 underground of the anthracite region, Mr. Lesquereux perfected 

 his S3'stem for identifying the dirterent coal-beds by their vege- 

 table fossils. Mr. Desor applied his Alpine studies to the local 

 drift, the outcrop marks of the region to be studied. I under- 

 took the task of mapping on a large scale, and representing in 

 light and shade the surface aspects, the outcrop terraces, the 

 sandstone ribbing of the gaps, the varied erosion of the crests, 

 and the relationship which the opened gangways bore to these. 

 The Southern Basin, from ten miles east of Pottsville to twenty 

 miles west of it, was cross-barred in parallel lines, one or two 

 thousand feet apart, running from the crest of the Sharp Moun- 

 tain, about N. 2.5"^ W. to the crest of the Broad Mountain, and 

 in some cases to the summit overlooking the valley of the Ma- 

 hanoA*. These lines, measured, levelled, and staked, were tied 

 together by transverse staked and levelled lines, one set running 

 along the hill tops, another along the valley bottoms. To this 

 system all the railroad surveys were tied ; the branch roads, 

 gangways, trial and air shafts were located properly ; and in a 

 few indispeusible cases, where beds had not been opened, new 

 trial shafts were made. 



Six months passed thus, every working moment occupied. 

 The map advanced as the surveying furnished the material. Still, 

 quite as much remained undone. Another year was wanting to 

 complete the first and second basins, to say nothing of the third. 

 But Mr. Rogers could not keep his corps together. The follow- 

 ing spring he employed a land surveyor (Mr. Poole) to com- 

 plete the map as far as Mauch Chunk, and joined with him a
