Contact with the earth in the burrow and with the wet feet of the sitting bird, soon discolours this egg, and renders it almost like a ball of peat in appearance. When disturbed at their breeding places, such Puffins as may chance to be outside the holes soon fly off to the sea, and join the hosts of birds that swarm in the water near every breeding station. Those in the burrows, however, remain, allowing themselves to be dragged out without making any attempt to escape. Great caution and gloves are recommended, for the Puffin resents intrusion and bites fiercely, being able to inflict a nasty cut with its powerful beak and sharp claws. I still retain the most vivid impressions on my visit to the grand colony of Puffins on Doon, one of the St. Kilda group. Every available place is honeycombed with their holes; the ground cannot afford accommodation for all, and numbers of birds have to seek nesting places under the masses of rock lying on the grass-covered hillsides, or in the crannies of the cliffs at the summit of the island. As soon as we had fairly got ashore, and begun to walk up the slopes, the Puffins, in a dense whirling bewildering host, swept downwards to the sea, or rose high in air to circle above our heads, in the direst alarm. It seemed as if the whole face of the island were slipping away from under me, just like flakes of shale down a quarry side! Not a single bird, so far as I could ascertain, uttered a note, but the whirring noise of the millions of rapidly beating wings sounded like the distant rush of wind! But even Doon does not harbour so many Puffins as find a home on the face of the mighty cliff Connacher; and when we fired a gun and disturbed them from this noble precipice, it seemed as though the face of the entire cliff was falling outwards into the Atlantic, the enormous cloud of birds overpowering one with its magnificence! As soon as the young are reared the land is deserted, and the wandering pelagic life resumed. In connection with this species mention may be made of its former repute as an article of food. Old records inform us that the young Puffins were regularly gathered by the owners of the breeding-places, and were salted down for future food. Gesner and Caius assert that the Puffin was allowed to be eaten during Lent, probably because, in the words of Carew, of its coming nearest to fish in taste. More than two hundred years ago Ligon, in his _History of Barbadoes_, complains of the ill taste of Puffins which he had received from the Scilly Islands (once a great centre of exportation of these birds), and asserts that this kind of food is only for servants. The taste for salted and dried Puffin, however, still lingers in the land; for at St. Kilda vast numbers are caught, and so preserved by the natives for food. Dried Puffin, perhaps a twelvemonth old, is one of the few delicacies of the island; whilst the feathers help materially to pay the rent! _Divers, Grebes, and Cormorants_
