282 REMAINS OF A SUPPOSED PILE-DWELLING. required to light a fire in the centre of the bed of an artificial pool, or, even if he did so, why he should burn in' it a large quantity of flints and other stones. Moreover, the fact that the undisturbed sandy clay on which the deposit rests shows no sign of the action of fire is strong evidence that the burning did not take place in situ ; while the extent of the deposit (even if no greater than is now visible) is also against the idea that it is merely an ancient domestic hearth. The only suggestion I am able to offer in explanation of the presence of the deposit is that, over the spot where we find it (that is to say, about the centre of the pool), there was once a pile-dwelling which, through some misfortune, was destroyed by fire, and that, as it burned, the flints and other stones which formed the floor fell to the bottom of the pool, together with the ashes and other remains of the dwelling. The spot is just such a one as would be chosen as a dwelling place by Early Man, for it is well concealed, and in former days the surrounding country was even more densely wooded (as the name of the parish implies) than it is now. The theory I advance, though admittedly in need of further support, is plausible at the least, and may serve till a better is forthcoming, Since I first discovered the deposit, I have visited it in company with Mr. Mothersole, of Chelmsford, who had no better suggestion to make. The only means of putting the theory to the test, and of ascertaining definitely the origin and extent of the deposit is, of course, to excavate its site by means of the spade. If this were done, fragments of pottery or other objects of human handiwork, sufficient to afford evidence as to its date and origin, would probably be brought to light. It seems very desirable that such investigation should be made. Who will undertake it ?
