Earthquakes are, and ever have been, very frequent through the whole of Mexico. Yet they have never been very severe, particularly at the city, as is demonstrated by the very existence of a city upon such a mass of soft earth as I have shown in a former chapter constitutes the foundation of Mexico. A reasonable amount of hard shaking would dislocate its muddy basis and engulf the city. Now and then some unusually frail structure is toppled down, and the church steeples are swayed a little this way or that, but the cement that sustains them has heretofore proved sufficiently cohesive to save them from being shaken to pieces or tumbled down.[60] Some ten years ago, the convent church, in which was the miraculous image of our Saviour, was thrown down, and the image that had annually poured forth its precious blood for the healing of the spiritual and temporal maladies of all pious believers was buried under the ruins. But this calamity was only a precursor of a greater miracle; for, on removing the rubbish, the sacred image was found intact, and as ready as ever to bleed again to order for ready pay. The spiritual interpretation of this astounding phenomenon was, that the devil, in his malice, had attempted, as of old, to crush the miraculous power of the Saviour; and now, again, as upon the high mountain, he was foiled, and the flow of blood was not intermitted.
