more applicable to these shores. However, if you should sail all the way from Greenland to Buzzard's Bay along the coast, you would get sight of a good many sandy beaches. But whether Thor-finn saw the mirage here or not, Thor-eau, one of the same family, did; and perchance it was because Lief the Lucky had, in a previous voyage, taken Thor-er and his people off the rock in the middle of the sea, that Thor-eau was born to see it.
This was not the only mirage which I saw on the Cape. That half of the beach next the bank is commonly level, or nearly so, while the other slopes downward to the water. As I was walking upon the edge of the bank in Wellfleet at sundown, it seemed to me that the inside half of the beach sloped upward toward the water to meet the other, forming a ridge ten or twelve feet high the whole length of the shore, but higher always opposite to where I stood; and I was not convinced of the contrary till I descended the bank, though the shaded outlines left by the waves of a previous tide but half-way down the apparent declivity might have taught me better. A stranger may easily detect what is strange to the oldest inhabitant, for the strange is his province. The old oysterman, speaking of gull-shooting, had said that you must aim under, when firing down the bank.
A neighbor tells me that one August, looking through a glass from Naushon to some vessels which were sailing along near Martha's Vineyard, the water about them appeared perfectly smooth, so that they were reflected in it, and yet their full sails proved that it must be rippled, and they who were with him thought that it was a mirage, i. e. a reflection from a haze.
