JLehigli. Surveyed in 1874-'75 by F. Prime. See Reports on the Iron 

 Ore district, D (1875), D 2 (1878), with atlas. Note— The dehxy of the 

 last report was occasioned by the fact that the instrumental survey of the 

 limestone valley belt and of the mountains continued from year to year, 

 and was not finished until 1882. The survey of the slate belt in 1881 

 by R. H. Sanders will appear in the Report; on Lehigh and Northamp- 

 ton D 3, with atlas, mostly printed and to be published shortly. 



Liuzerne. Parts lying outside the coal, surveyed in 1882 by I. C. 

 White. See forthcoming Report G 7 (1883). Coal basin survey by C. 

 A. Ashburner and corps, commenced in 1881 and continued through 1882 

 and onwards. Western sheets ready for printing. Middle sheets in prepa- 

 ration. A special report will accompany the sheets of each division. 



liycoming. Surveyed in 1877 by A. Sherwood, and again in 1878-'79 

 by F. Piatt. See Report on Lycoming and Sullivan, G 2 (1880). Note. 

 —The delay was caused by imperfections in the first survey, which could 

 not be corrected sufficiently early in 1878. 



McKean. Surveyed in 1876, 1877 and 1878, by C. A. Ashburner and 

 A. W. Sheafer. See Report R (1880). Note— The length of this sur- 

 vey was due to the amount of instrumental work needful for its study ; 

 and the delay of its publication, to the careful preparation of its atlas of 

 illustrations. The geology of Cameron, Elk and Forest was studied pre- 

 liminarily in connection with that of McKean ; and afterwards separately 

 and in detail.
