the rocks my heart bled for our friend's property,—of which he was justly proud. He abstained even from a look of dismay as we came smashing down from stone to stone. Every now and then we heard that a bolt had given way, but were assured in the same breath that there were enough to hold us together. We were held together; but the carriage I fear never can be used again. The horses perhaps with time may get over their ill usage. We were always going into a river or going out of it, and the river had succeeded in carrying away all the road that had ever been made. Unless the engineers go seriously to work I shall be the last stranger that will ever visit the Cango Caves in a carriage.
