The Spaniards have been celebrated above all other people for fortifications. They have left monuments of their patience, diligence, and skill all over the world, wherever they have obtained a foothold.

But to return to our tour of inspection. The famous underground ‘galleries’ of the Rock of Gibraltar, are huge tunnels, blasted and bored, foot by foot, in the living rock, sufficiently wide and deep to admit of the placing, and working of heavy artillery.
