They crossed without mishap, and, having shod themselves again, mounted the turfy slope where the larks flew up from their hiding-places among the stones. Vashti's talk was of the birds, for in all Brefar the spot best worth visiting is Merriman's Head, where the birds congregate in their thousands--cormorants, curlews, whimbrels, gulls and kittiwakes, oyster-catchers, sandpipers--these all the year round--and in early summer the razorbills and sea parrots. Zenobia, it appeared, knew not only Merriman's Head, but every rock, down to the smallest and farthest in the Off Islands, where these creatures nested. She spoke to them of the island from which Annet took her name--a low-lying ridge to the west of St. Ann's, curved like a snake, in nesting-time sheeted with pink thrift. There the sea-parrots breed, and so thickly that you can scarcely set foot ashore without plunging into their houses; but there is a mound near the western end where no sea-parrot may come, for the herring-gulls and the black-backs claim it for their own. She spoke of Great Rose, still further westward, where the gulls encamp among the ruined huts once used by the builders of the Monk Lighthouse; of Little Rose, where the great cormorant is at home; of Melligan and Carregan, the one favoured by shags, the other by razor-bills and guillemots. And so talking, while they wondered, she brought them across the hill to the great headland. Merriman's Head, in truth, is itself an islet, being cut off from Brefar by a channel, scarcely eight feet wide, through which the seas rush darkly with horrible gurglings. The cleft goes down sheer, and was cut, they say, with one stroke of a giant's sword. Beyond it the headland rises grim and stark--a very Gibraltar of the birds, that roost in regiments on its giddy ledges. As the children came down to the brink a flock of white gulls seemed to drop from the rock, hung in the air for a moment, and began wheeling overhead in wide circles, uttering their strange cries. A score of little oyster-catchers, too, tucked up their scarlet legs and skimmed off in flight. But the majority kept their posts and looked down almost disdainfully. "They know we can't get to them," said Matthew Henry. "But wait till I am grown up! Then I'll come over to Brefar and build a bridge." "You will not need a bridge when you are grown up," said Vashti. "See!" She stepped back a pace or two, and the children, before they guessed her purpose, saw her flash past them and leap. She cleared the chasm, easily alighted, and stood smiling back at them, while the birds poured out from their ledges, cloud upon cloud of them. Their wings darkened the air. Their uproar beat from cliff to cliff, and back again in broken echoes, like waves caught in a narrow cave and rebounding. Vashti looked up and laughed. Like a witch she stood, waving her arms to them.
