sure. Its specific gravity is very high, the stone weighingupwards of 150 lbs. the cubic foot. The cohesive poweris very great, and hardly rivalled by any limestone.—D. T. A.] _
188 Stocks, Michael, Shebden Hall , near Halifax —
Proprietor.
Specimens of ashlar building stone, from the Shebden-head quarries, near Halifax. The seam from which thespecimens are obtained is between the lowest, or “Halifaxbeds,” and the “Lowmoor beds” of coal; and betweenthe lowest of the latter, or “better bed” coal, and theNortliowram flag-stone. The Halifax beds of coal imme-diately overlie the millstone grit.
[The coal grits of Yorkshire supply a very good build-ing material, well adapted for local purposes. Wherethere is not too large a proportion of organic impurities,the sandstones of the coal measures may often be de-pended on; but there is apt to be a want of cementingingredients to bind the sand and gritty particles toge*fcher.—D. T. A.]

[The different building and road materials, above re-ferred to, will be found to present some rocks of con-siderable interest, hitherto little used for economic pur-poses. The marbles and other calcareous rocks are allfrom the carboniferous limestone, and entirely confinedto the southern extremity of the island, near Castletown,where they occupy about 16 square miles, for the mostpart covered by tertiary gravel. The sandstones, schists,and granites are more abundant, but less valuable.
Of the calcareous rocks, the black flagstones of Poolvashcontain much carbon and some argillaceous matter, andare very durable. The different marbles have the sameproperties as the carboniferous limestones of Derbyshire;and the porphyritic rocks are generally of good quality. -D. T. A.]_
