and it was for a time turned to account for the manufacture of lamp- 
black. Burning jets of gas were made to impinge on slabs of soap stone, 
and the accumulated carbon was automatically removed by a scraper. 
The lamp-black was of excellent quality, and was used for the manu- 
facture of printer’s ink, etc. The works have recently been burned, and 
the gas is about to be utilized in Porter Smith & Co.’s fire-brick factory. 
ELLIOTSVILLE. 
Between McCoy’s and Hlliotsville, a distance of 1# miles, the “ clay 
seam ”’—Coal No, 3—is well exposed, running nearly parallel with the 
railroad, and from 8 to 4 feet above its grade. The clay is worked at 
several places, viz.: at the establishment of Messrs. Porter & Miner, where 
it is manufactured into fire-brick of good quality ; by Messrs. Garlick & 
Sizer, and Mr. Jno. Freeman in their pipe works, and at the ‘“ Excelsior 
Works” (Conner Bros.) 
At Porter and Miner’s a good coal 38 feet in thickness is found about 30 
feet above the “clay seam.” This is coal No. 4—the “ Block ” or “ Strip” 
Vein. <A well bored here is reported to have passed through 54 feet of 
coal 80 feet below the ‘‘clay seam,” but the distance is probably greater 
and the coal the same as that found at New Cumberland, and proved by 
trial to be worthless. About a quarter of a mile above Elliotsville, at 
Freeman’s terra cotta and drain-pipe works, the following seetion was 
observed: °

The openings in the upper coal, No. 7, are now all abandoned, and the 
coal here called No. 5 is regarded by the residents of Hlliotsville as the 
Roger Seam of Yellow Creek. This was at first supposed to be impos- 
sible, as its distance above the “clay coal” is so great—130 feet—and 
there is an intervening coal, No. 7, of the above section, which corres- 
ponds better in position to the Roger Vein, but a comparison of the
