As we were anxious to see the Land's End, and could not approach the point in the yachts without risk, we determined to visit the famous promontory by land.  Engaging a carriage, we set off, making a circuit to see several curiosities on our way.  First we stopped at a cave, apparently part of a fortification.  Near it are two upright granite rocks, fifty yards apart, said to form the head and foot-stones of a Cornish giant.
