fhells, both univalve and bivalve, many of which are yet perfe, forming a fratum feveral feet in depth of pure calcareous earth; but the exa depth of this bed of marl has never yet been aſcertained, for want of a proper level to carry o the water: It probably may afford matter of ſpeculation to ſome readers to be informed, that in the middle of this marl there is an horizontal ſtratum of ſand about 12 inches thick; and alſo that, a few years fince, a Red Deer Stag, in the attitude of running, and in every part complete,‘was found embedded in the marl; horns of the ſame animal have been found at diferent times in perfed preſervation; and a part of the ſcalp, with the cores of a pair of horns belonging to ſome animal of the Bos Taurus ſpecies, were lately found here: we have never ſeen any breed of cattle, the horns of which were of equal magnitude; for though the outſide ſhell or horn part was wanting, yet the cre was 24 inches long, and 12 inches circumterence at the root; and when in a perfe ſtate and covered with the outfide ſhell, muſt have been about g inches diameter: their form is a gentle curve, and have all the appearance of a pair of bull’s horns; but probably of a different breed of cattle to any we have at preſent.

Clay Marl,—is alſo found in ſmall quantities, but in fitu- ations where it could not be conventently uſed with efect,

Lead Ore,—has hitherto never been found in any quan- tity but in the mountainous diftriés on the ſouth-weſt part of the county, towards the head of that branch of South Tyne, called Allendale; and a ſmall quantity at Fallowfield, a little to the north of Hexham,*

In this county, lead ore is wrought by the Zing, a meaſure containing 8 cwt. of clean ore; the workmen being paid by the owners of the mine at different prices,

* The lead mines in Allendale produce about 12000 bings of lead ore annually, which at 41. 45. od. per bing, is upwards of

50090L a year. SZ from
