The neighbourhood of Pateley-bridge possessing many water-falls on which more mills might be built, gave rise to an idea of cutting this last-mentioned stone by water-sawing, into scantlings for fire-places, hearths, and slabs; but upon an experiment being tried, it was found to contain what is termed the dry heads, which cause a division of the parts when brought into service, otherwise it yields a beautiful polish, and exhibits much of the shell and feather; but notwithstanding this last attempt hath failed to augment its value, another in reserve still remains of no small moment, which is that of the most excellent GREENHOW-HILL LIME. In the district where it has long been used as a manure either for arable or grassing land, no comment on its superior utility is requisite; but to those parts where its presence hitherto hath been forbidden by the rugged and steep hills, and to others at too great a distance to warrant the expense of a long land carriage, something of its superior quality as a manure in this place may not, we hope, be deemed unseasonable, especially as the carriage of it, when the Railway is constructed, will be an object of less notice, and this will be exemplified hereafter. We have said before, the stone of Greenhow-hill has been submitted to analysis, to prove a corresponding property with that of Middleton-Tyas; this inquiry was extended to ascertain if they produced similar lime, and we have great satisfaction to inform the public this was the case. We say a great satisfaction, because we have it in proof, that the Middleton-Tyas lime is situated in a country, where a knowledge of its excellence is not confined to narrow limits by steep and forbidding hills, but being more favourably situated, it has been for a great number of years, and is now, with increasing demand, conveyed generally 17 or 18 miles, and in some instances, into the immediate vicinity of other kilns, even at 24 miles distance. The reader will be best able to calculate the expense of this lime to the consumer, when he is informed that the cost at the kilns is 12s. per chaldron of 32 bushels Winchester, one of which weighs 7st. 8lb.
