Papa told us it was the opinion of geologists that the surrounding rocks, as well as the Scilly Isles, were once connected with England. Indeed, of that there can be no doubt.  Tradition declares that articles have been fished up proving that cities once stood on spots over which the tides now ebb and flow; but then tradition is the most uncertain of all uncertain things.  Although an iron kettle may have been fished up from the bottom of the sea, it might only show that it had been thrown overboard, or washed out of a sunken vessel.
