Ajrcadj pooplc everywhero ■ee o'.early that the trunk lino frcm the Clieapeake to the Ohio is to be cno of ih most important iu cur country; and wbatevar Cinoinnati may do for herself, the e ties norih of her will, you may depn'l upoa. it, o:jnneot theiüje'ves with tfw great üue. Tharn are niready, F think, thrco linas in the interior, now pUnnfld and baius? survayed to conooct with the great Qkegipeake 1 ue. The line frnm To'.edo to P.im-eroy will conneut with the Gliesnpeake roud, by a hort at the nio i'h of the Kanawha. The primary o'ijast, boweTor, of the Toledo and Porneroy line is to reach the great coal and Timi beds. A straight line fi'oui Toledo to I'omsroy (and tho proposed routo is as neor traight as railroaiis can be made), will pass through ttiis place (Granville), ond ; oon aftr strike the coal reeion. 1 fsring Perry county from tLe nortn, we Btou gei i:ito the threkf st teds df coal ; in the State. At Str.ightsv;!le, and ! in tbe m-ighborhood, hre i nmeuse beds f eTceilent cosí, asid iha natural wea'.th of tbat región is nlniost incalcuable. If ! eur geologis's wculd go to work and i describe defin and measure the coal i bed, the iron strata, and the suliferous rocks of Southeastern Oiiio, tiiey would do the State more g-"od tban they can do iu a thousand yearu of vin speeu'ations upon tho probiem of creation, or ia describing tlie sume üies, whioh they ■ay are abundant in the s'.rata bclow. They were cvea'ed BOT.ehuw, and thu hotc ia not the milüontb part of the im portanee as the uhat comes of it. Pnesrng through the immense bed of coal in the south half cf Perry eouuiy, we soon reicii the salift;r.iu3 rocks. The new road will strike Nelsonrille, and go through Atfaeoa to Pomeroy. There we reach u gre t deposit of alt At about 1,000 or 1,200 fect lielow the surface, ure the ealt work?. From tho eai lies-t ettleraenl of this State salt has been made on the Muskingum and Hocking, but it is only iu reeent ycars tb.'it its produetion at Portsmoutn lias becotoe of importance.
