ST.MICHAEL'S-MOUNT, (Cornwall) in the corner of Mount's-Bay, is a pretty high rock, only divided by the tide from the main land, so that 'tis land and island twice a day. The T. here was burnt by the French in the R. of K. Hen. VIII. K. Cha. I. imprisoned the D. of Hamilton here, till the Pt. took it, and released him. Upon the top of the rock, within the fort, was a chapel dedicated to St. Michael the archangel, and an alien priory, where some of the Cornish gentry took refuge formerly, during the civil wars, as did the Lady Ann Gordon, wife of Perkin Warbeck; but it secured neither. At the Diss. of the alien priories, it was given to Sion Coll. near Brentford. At the bottom of this mount, in digging for tin, there have been found spear-heads, battle-axes, and swords, of brass, all wrapt up in linen. On the rocks along this coast is bred the Cornish chough, a bird which will not only steal money and hide it, but fire too, with which it sometimes privately burns houses. The Co. is contracted here into a sort of isthmus; so that it is scarce 4 m. bet. the Channel and the Severn sea. There have been large trees driven in by the sea bet. this mount and Penzance.
