The top of the true peat is found at various depths, from one foot to eight feet below the surface of the ground; and the depth or thickness of this peat is also very different, from one foot to eight or nine feet, the ground below it being very uneven, and generally a gravel. My friend Mr. Osgood has dug two feet into this gravel, to see if any peat lay below it, but could not find any.
The truest and best peat has very little (if any) earth in it; but is a composition of wood, branches, twigs, leaves, and roots of trees, with grass, straw, plants, and weeds; and lying continually in water makes it soft and easy to be cut thro' with a sharp peat-spade. The colour is of a blackish brown; and if it be chewed between the teeth it is soft, and has no gritty matter in it, which the clob has. It is indeed of a different consistence in different places, some being softer, and some firmer and harder; which may perhaps arise from the different sorts of trees it is composed of.
To get at the peat, they first dig up the surface of the ground till they come to the clob, throwing the earth into the empty pits, from which they have already cut out the peat: they then dig up the clob, and either sell it to the poor for firing, or lay it in heaps, to burn to ashes, to be sold to the farmers. Then they cut out the true peat, with a peculiar kind of spade, in long pieces, vulgarly called long squares, about three inches and a half broad every way, and four feet long, if the thickness of the peat will allow that length: and as they cut it out in long pieces, they lay them in a regular order carefully, in rows upon the ground, to be dried by the sun and wind. If the peat be thick, when they have cut one length of the spade for some distance, they return again, and cut down another length of it (or four feet), and so on, till they reach the gravelly bottom, if they can sufficiently drain it of the water, which continually comes in, tho' proper persons are employed to pump out as much of the water as they can all the time. As the peat dries, and is turned by persons appointed for that purpose, to dry it the better, it breaks into smaller lengths, and then it serves not only the poor; but many other persons, for firing, and gives a good heat. It is sold for about ten shillings a waggon-load, delivered at their houses in the town. The ashes also prove very good manure for both grass and arable land; and the farmers give from four pence to six pence a bushel for them, which renders this firing very cheap.
Great numbers of trees are plainly visible in the true peat, lying irregularly one upon another; and sometimes even cart-loads of them have been taken out, and dried for firing: but the nearer these trees lie to the surface of the ground, the less sound is the wood: and sometimes the small twigs, which lie at the bottom, are so firm, as not to be easily cut thro' with the usual peat-spade. These trees are generally oaks, alders, willows, and firs, besides some others not easily to be known. The small roots are generally perished; but yet have sufficient signs to shew, that the trees were torn up by the roots, and were not cut down, there being no sign of the ax or saw; which, had they been felled, would have been plainly visible.
No acorns are found in the peat, tho' many cones of the fir-tree are, and also a great number of nut-shells. They are all of a darkish colour; and the nuts are hollow within, and some of them have a hole at the broad end.
A great many horns, heads, and bones of several kinds of deer, the horns of the antelope, the heads and tusks of boars, the heads of beavers, &c. are also found in it: and I have been told, that some human bones have been found; but I never saw any of these myself, tho' I have of all the others.
But I am assured, that all these things are generally found at the bottom of the peat, or very near it. And indeed, it is always very proper to be well and faithfully informed of the exact depth and place, where any thing of these kinds is found; whether it is in the earth above the peat, or in the clob; or in the true peat, or at the bottom of it; which will greatly assist us in forming a just judgment of the real antiquity of the things that are found, or at least of the time they have lain there. Besides this, as they formerly used to cut out the peat in large plots here and there, leaving spaces full of peat between those pits (whereas now they draw off the greatest part of the water by pumps, and so clear out all the peat regularly as they go on); so it must be carefully observed, whether whatsoever is found here be dug out of these old peat-pits, or not; for axes, and other things, may have been formerly dropt into these pits, before they were filled up again with earth, and may now be dug out of them again. My father has now in his possession an iron hatchet, not greatly differing from the modern form, which was found lying flat at the very bottom of the peat: it was covered with a rust near half an inch thick, and the handle was to it, which seemed to be of beech-wood, but was so soft, that it broke in bringing it up: but as the person is dead, who found it, I can't say whether it lay in an old peat-pit, or no.
Mr. Osgood found, some years ago, an urn, of a light brown colour, and large enough to hold above a gallon, in the true peat about eight or ten feet from the river, near a mile and a half west of this town, in Speen-moor. It lay about four feet below the level of the ground, and about one foot within the peat; and over it was raised an artificial hill, about eight feet higher than the neighbouring ground; and as the whole hill consisted of both peat and meadow-ground intermixed together, it plainly appeared, that the peat was older than the urn; and that the persons, who raised the hill, must first have dug a large hole in the peat, to bury the urn there, and so formed the hill of the peat and meadow-ground mixed together. Round the hill, where the urn lay, they had made also many half-circular ridges, with trenches between them, one beyond another, in this manner:
Where a is the river, and c the hill; and the half circles shew some of the ridges, the number of which Mr. Osgood has now forgot. The urn was broke by the peat-spade, and it came up only in small pieces, so that nothing was found in it; and no body happened to be there at that time but the peat-cutters.
