which, if broug-ht to the surface as a marketable commodity is 
valued at Is. 6d. per ton, the inside core of the bore-hole being- 
four inches in diameter. 
The sub-division of the Permian Rocks occurs in the order in 
which they have been observed to crop up to the surface — they 
have each their usual character. 
" There can be no doubt," says Mr. Greaves, " that the beds 
penetrated beneath the Permian Rocks are coal measures, and 
there are strong indications for believing* that they belong- to that 
part of the coal measures which contain workable seams of coal." 
The g-eneral character of the measures, the few fossils brought up 
in the cores, the clean and lustrous character of the thin seam of 
coal which has been passed through, all point to this conclusion ; and 
that in the future the best portion of the Yorkshire coal field will 
be found between Barnsley and Snaith. 
We shall hope that Lord Beaumont's restoration to health will 
enable him to continue this spirited investigation for coal, near 
Snaith, and that Mr. Greaves, the able and scientific pioneer of 
these sinking operations, may, at no very future date, be able to 
announce a discovery, that Lower Osgoldcross of 58,000, and 
Lower or one half of Barkstonash of 34,000 acres may be added 
as new coal fields to others in the County of York. 
The Aire and Calder Navigation was opened in 1787; and 
the Knottingley and Goole Canal in 1826, The tonnag-e now 
reaching Goole, arriving and departing by this Canal in 1880, was 
above 392,000 tons. The return for the port of Hull and Dock 
Company, from January 1st to 31st October of the current year, 
dues was equivalent to 2,100,358 tons ; and increase over 1881 of 
214,388 tons; whilst up to the 31st October, 1882, the export of 
coal had increased by G8,000 tons.
