various times dug up by the road-sides several skeletons of human beings, and of horses; they were in general but slightly covered with earth; and though the bones were much decayed, yet the teeth were sound, and appeared most commonly to have belonged to young persons, and probably had been deposited in their present situations at no very distant period of time. With the bones of a horse so found there remained the iron head of a lance, about a foot long, corroded, but not greatly decayed. Unable better to account for these skeletons, we suppose that they constituted, when alive, part of the forces of General Fairfax, and that they fell in some partial encounters with the peasantry when defending their property about to be plundered by the foragers of his army in 1645, at the time he was besieging the castle of Bristol. The siege lasted sixteen or seventeen days; many parties during that time must have been sent out by him to plunder us cavaliers, and contention would take place.

It is foreign to my plan to enumerate, and it might be difficult to discover, all the changes and revolutions which have taken place here; and I shall merely mention, that this district formerly constituted a regal forest, and we find Robert Fitzharding holding it by grant in the time of King John. We have a "lodge farm," it is true, and the adjoining grange, the "conygar," i. e. coneygard, the rabbit-keeper's dwelling, may, perhaps, have been the situation of the sylvan warren; but there are no remains, or any other indications, of a forest ever having been in existence. Names and traditional tales are all that remain in most places now to remind us of the ancient state of England, or to make credible the narratives of our old historians, who lived when Britain was a forest. Where shall we look for the remnants of that mighty wood, filled with boars, bulls, and savage beasts, that surrounded London? Even in our own days, heaths, moors, and wilds, have disappeared, so as to leave no indications of their former state but the name. Woods and forests seem to be the original productions of most soils and countries favorable for the abode of mankind, as if inviting a settlement, and offering mate

rials for its use. As colonies increase, wants are augmented; the woods are consumed; the plow is introduced, division of property follows; a total change and obliteration ensues, though the ancient appellation by which the district was known yet continues.

The parish consists in parts of a poor, shattery gray clay, beneath which we find, in some places, a coarse lias; in others a spongy, rough, impure limestone; in other parts a thin stratum of soil is spread over an immense and irregular rock of carbonate of lime, running to an unknown depth: this in many cases protrudes in great blocks through the thin skin of earth. The rock, though usually stratified, has no uniform dip, but trends to different directions; in some places it appears as if immense sheets of semifluid matter had been pushed out of the station it had settled in, by some other or later-formed heavy-moving mass, or met with an impediment, and so rolled up: that these sheets had not fully hardened at the time of being moved is yet made probable by the whole crystallization of the mass being interrupted; so that no part adheres firmly, but separates into small shattery fragments when struck. This substance we burn in very large quantities for building purposes, and for manure, which, by the facility which we have of obtaining small coal, is rendered at the low rate of three-pence a bushel at the kiln. Our farmers, availing themselves of this cheap article, use considerable quantities, composted with earth, for their different crops, at the rate of not less than a hundred bushels to the acre. This is a favorite substance for their potato land. The return in general is not so large as when grown in manure from the yard; but the root is said to be more mealy, and better flavored.

The utility of lime as manure consists in loosening the tenacious nature of some soils; rendering them more friable and receptive of vegetable fibres: it especially facilitates the dissolution and putrefaction of animal and vegetable substances, which are thus more readily received and circulated in the growing plant; and it has the power of acquiring and long retaining moisture; thus rendering a soil cool and nutritive to the

plants that vegetate in it. The power that lime has of absorbing moisture will be better understood, when we say, that one hundred weight will, in five or six days, when fresh, absorb five pounds of water, and that it will retain in the shape of powder, when slackened, or loosened, as is commonly said, nearly one-fourth of its weight.*

That lime rehardens after being made soft, as in mortar, is owing to the power which it has of acquiring carbonic acid-the fixed air of Dr. Black-from the atmosphere; when the stone is burned, it loses this principle, but re-absorbs it, though slowly, yet in time, and it thus becomes as hard as stone again: we unite it with sand to promote the crystallization and hardening. The utility of lime in various arts, agriculture, manufactories, and medicine, is very extensive, and in many cases indispensable; and the abundance of it spread through the world seems designed as a particular provision of Providence for the various ends of creation. Lime, and siliceous substances, compose a very large portion of the dense matter of our earth; the shells of marine animals contain it abundantly; our bones have eighty parts in one hundred of it; the egg-shells of birds above nine parts in ten-during incubation, it is received by the embryo of the bird, indurating the cartilages, and forming the bones. But the existence and origin of limestone are pre-eminent amongst the wonders of creation; nor should we have been able, rationally, to account for the great diffusion of this substance throughout the globe, however we might have conjectured the formation, without the Mosaical revelation. It may startle, perhaps, the belief of some, who have never considered the subject, to assert what is ap

*The weight of lime is very variable, differing in different places; but taking our lime at the average of eighty pounds to the bushel, some idea may be conceived of the cooling nature of this substance. Lime, to be used as manure, must be in a pulverized state; and by drawing on the land the quantity that we do, we convey to every acre so dressed equivalent to two hundred and fifty gallons of water, not to be evaporated, but retained in the soil as a refrigerant to the fibres of vegetation.

parently a fact, that a considerable portion of those prodigious cliffs of chalk and calcareous stone, that in many places control the advance of the ocean, protrude in rocks through its waters, or incrust such large portions of the globe, are of animal origin-the exuviæ of marine substances, or the labors of minute insects, which once inhabited the deep. In this conclusion now chemists and philosophers seem in great measure to coincide. Fourcroy observed, forty years ago, that "it could not be denied, that the strata of calcareous matter, which constitute, as it were, the bark or external covering of our globe, in a great part of its extent, are owing to the remains of the skeletons of sea animals, more or less broken down by the waters; that these beds have been deposited at the bottom of the sea, immense masses of chalk, deposited on its bottom, absorb or fix the waters, or convert into a solid substance part of the liquid which fills its vast basins."-Supplement to Chemistry, p. 263. Such are the conclusions of philosophical investigation; and the discoveries of all our circumnavigators fully corroborate these decisions as to formation. Revelation in part accounts for the removal of these stupendous masses; though, probably, unrecorded concussions since the great subversion of our planet have, in remote periods, effected many of the removals of these deposits. We find the basement of many of the South Sea Islands, some of which are twenty miles long, formed of this matter. Captain Flinders, in the gulf of Carpentaria, held his course by the sides of limestone reefs, five hundred miles in extent, with a depth irregular and uncertain; and still more recently Captain King, seven hundred miles, almost a continent, of rock, increasing, and visibly forming:-all drawn from the waters of the ocean by a minute creature, that wonderful agent in the hands of Providence, the coral insect. This brief account of the origin of calcareous rocks was, perhaps, necessary before mentioning an extraordinary fact, that, after the lapse of so vast a portion of time since the basement of the mighty deep was heaved on high, existing proofs of this event should remain in our obscure village.

The limestone rocks here are differently composed, but are principally of four kinds-a pale gray, hard and compact; a pale cream-colored, fine-grained and sonorous: these form the upper stratum of stone on our down, a recent deposit, or more probably a mass heaved up from its original station. The whole of this mass, running nearly half a mile long, is obviously of animal formation, a coral rock; a compounded body of minute cylindrical columns, the cells of the animals which constructed the material, the mouths of which are all manifest by a magnifier. The stop in the progress of the work is even visible; soft, stony matter having arisen from some of the tubes, and become indurated there in a convex form; in others the creatures have perished, but their forms or moulds remain, though obscure, yet sufficiently perfect to manifest the fact: these tubes, by exposure to the air for any length of time, have the internal or softer parts decomposed, and the stone becomes cellular. This stone burns to a fine white lime, and is very free from impurities, containing in a hundred parts

Another quarry presents, likewise, unquestionable evidence of an animal origin, veins of it being composed of shattered parts of shells, and marine substances, greatly consumed and imperfect, embedded in a coarse, gray, sparry compound; an ocean deposit, not a fabrication, and consequently has more impurities in its substance than that of insect formation: it contains about

I have called this alumine, stained with oxide of iron; but it seems more like vegetable or animal remains, adhering to the filter like a fine peaty deposit, and is lost in combustion.
