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 Elliotsville, a distance of If miles, the " clay 

 seam " — Coal No. 3 — is well exposed, running nearly parallel with the 

 railroad, and from 3 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 & 

 8izer, and Mr. Jno. Freeman in their pipe works, and at the " Excelsior 

 Works " (Conner Bros.) 



At Porter and Miner's a good coal 3 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 5^ 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 section 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 Elliotsville as the 

 Koger 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-
