ON A RECENT SUBSIDENCE AT MUCKING, ESSEX. 253 15 (1858), we learn that "stones for grinding wheat, nay, large quantities of that grain itself, apparently charred, were found in what had been a subterranean granary in one of the Castella" (Castlecarey). It is also worth recording here that in the Gentleman's Magazine Library (Romano-British Remains, Part. II., p. 352) it is mentioned that in the old British camp in Wiltshire, known as Battlesbury, "a quantity of parched corn was found, some years ago, curiously preserved underground in a sort of stone trough." Battlesbury is near Warminster, and stands on the western edge of Salisbury Plain. The date of this account of Battlesbury is 1787. It may also be useful to note in this place that a brief account is given in Trans, Essex Field Club, Vol. iv., pp. 108-110, of ancient British subterranean granaries discovered in the camp known as Winklebury, on the borders of Wiltshire and Dorset, and of others in the Isle of Portland. A consider- able amount of blackened corn was found in them at both the places mentioned. Deneholes in the Chalk, even when destroyed (for instance) during the enlargement of a great chalk-pit, are visible during the progress of their destruction. If, like those of Hangman's Wood, and of Stankey and Cavey Spring, Bexley, they exist in groups which have made the areas they occupy useless for other purposes, they retain for centuries a certain proportion of open shafts, which allow their characteristic features to be noted. Consequently, whatever may be the views held by their explorers as to the purposes of their makers, to all they are obviously ancient and remarkable. But the shallower subterranean storehouses, in sand, gravel, and clay, would very seldom have their existence revealed except when the sudden collapse of their chambers disclosed their sites. When this occurred, they would be much more likely to have their true nature and former uses recognised by farmers and labourers whose families had long been resident in the locality, and who possessed traditional information about them, than to attract the attention of a local antiquary. For, apart from the fact that antiquaries are few in number, they naturally tend (like Mr., Clowes) to be interested in a rude subterranean chamber only when it contains coins, pottery, or inscriptions, and not when it
