76 THE ESSEX NATURALIST. described by the Magpie, where he discovered the entrance to an underground passage, through which he passed. In due course he came to a cavern, bright with silver, but not forgetting the Magpie's advice went on until he reached a second cave, this time shining with gold. This was more than he could resist, so he plunged his bill greedily into the golden dust, which carpeted the floor. At once a terrible demon appeared, emitting fire and smoke, who rushed at the terrified bird with such alarming speed that he escaped by a hair's breadth ; but he did not escape unscathed, for the dense smoke had coated his feathers and he was now quite black with the exception of his bill, which still retains the colour of the gold he attempted to take away. Even today when the Blackbird is surprised he utters cries of terror, such as were compelled by the monster. The imaginations of the folk did not seem to react readily to Geese as there is not much lore bearing on these and similar types of birds. A quaint conceit existed regarding the origin of the Barnacle-Goose. Gerard's account was that Barnacles were produced in the North of Scotland and the Orkney Islands. He tells "what his own "eyes have seen and hands have touched." On a small island off Lancashire, called the Pile of Foulders, were found parts of old ships, also trunks and branches of old rotten trees, cast up by the waves, on which was found spume or froth, which in time bred into certain shells, shaped somewhat like mussels and of a whitish colour. These shells contained an object resembling a lace of silk, one end of which adhered to the inside of the shell. The other end was attached to the belly of a rude mass or lump, which in time assumed the form of a bird and when its form became perfect the shell opened. The first thing to appear was the lace or string, then the legs of the bird hung out, and so the shell was gradually opened until the whole bird was in view and hung only by the bill. Soon it came to full maturity and fell into the sea, where it gathered feathers and grew to a fowl, larger than a Mallard and smaller than a goose, having black legs and bill, and black and white feathers spotted like a Magpie. Gerard added: "For the truth hereof, ''if any doubt, may it please them to repaire unto me, and I ''shall satisfie them by the testimonie of good witnesses." A story of the same nature, but with a different origin, relates to the
