Provisions of all sorts are exceeding cheap and plentiful in Dacca: the fertility of its soil, and the advantages of its situation have, long since, made it the centre of an extensive commerce; it has still the remains of a very strong fortress, in which, a few years back, was planted a cannon of such extraordinary weight and dimensions, that it fell into the river, with the entire bank on which it rested; the length of the tube was fourteen feet, ten and a half inches, and the diameter of the bore one foot, three and one eighth inches: it contained two hundred and thirty-four thousand four hundred and thirteen cubic inches of wrought iron, weighed sixty-four thousand four hundred and eighteen pounds avoirdupoise, and carried a shot of four hundred and sixty-five pounds weight.
