Moral writers used to commiserate the poor blind Mole for having to expend its energies in ceaseless toil in the dark underground, and then rhapsodise on its marvellous adaptation to its rôle in nature, getting lost in admiration of the mathematical skill displayed in the construction of the "fortress" they had never seen and which was largely an imaginative piece of engineering. It is true that its body may be said to fit the tunnels it has excavated, though it might be more accurate to say that the tunnels are modelled upon and by the Mole's form, for it is the constant passage of the animal backwards and forwards that smooths and consolidates their walls. The sense of sight is of less importance to it than that of smell, which is apparently its most highly-developed sense, though that of hearing is very acute.
