and seemed to be made up only of the shivers, or husks, and otherparts of juli of hazel, alder, poplar, &c. There is also great quanti-ties of this kind of turf in the northern parts of Yorkshire , and inthe bishoprick of Durham . About a mile from Langrow, in Cum-berland, is a stratum of bituminous earth, three feet thick, whichcontains parts of the trunks of trees, leaves, sprays of shrubs, andother vegetable substances, in such quantity that the far greaterpart of the stratum seemed to be formed by them. It also aboundsnear Outhorn in Yorkshire , at Kendall in Westmoreland, in Wind-sor Forest, in the Isle of Wight, and various other places. In thatwhich was dug up in the Isle of Wight, besides the twigs and leavesof hazel, were found several hazel nuts, the shells of which were un-broken, but the kernels were decayed.

How extensive and considerable the beds of peat may be in thevicinity of the metropolis, may be inferred from the following cir-cumstance:—Near a hundred years ago, in digging a wet dock atDeptford, hazel nuts, with hazel, oak, and several other kinds oftrees, were found. Within these few years, in digging the wet-docksof Mr. Perry, at Blackwall, on the opposite side of the river, and atthe distance of nearly two miles, a similar stratum was dug into,yielding peat for a considerable thickness, in which were foundhazel nuts, trunks of large trees, &c. In digging also, in the ad-joining marshes, called the Isle of Dogs, lately, for the purpose offorming similar docks, wherever the earth was opened, over anextent of several acres, peat was also found, with hazel nuts, andseveral trees ; these were chiefly oak, yew and hazel, and a few firs:but the latter, as I am informed, were but of a very small size. Atthe depth of about six, eight, or nine feet were also found bones ofseveral animals, apparently of horses and oxen, and the fragmentsof the horns of deer.

In almost every morass, which has been dug in the isles of An-
