No more likely place could be found for the great birds to rear their young; the cliff looked inaccessible, and days would pass, sometimes weeks, and not a soul come near. "Old Master Rayburn must be right," thought the lad. "What eyes he has for everything of this kind. There are no rooks in the beeches; there isn't a jackdaw about; and I haven't seen a rock-dove; all proof that the ravens are here, for the others would not dare to nest near them. Only be to hatch young ones for food. But I don't see my gentleman nor his lady." A hoarse, distant bark was heard, just as the lad's neck began to ache with staring up in vain, in the search for the nest, and he sat perfectly motionless, crouched amongst the hemlock and heracleum, to be rewarded by seeing a shadow thrown on the white limestone far on high, and directly after one of the great glossy black birds alight, right on the edge of the cliff, from whence it hopped into the air, and seemed to let itself fall some forty feet, down behind a stunted patch of broom, which had rooted in a cleft. There it disappeared for a few moments, to reappear, diving down toward the stream, but only to circle upward again, rise higher and higher, and finally disappear over the cliff, half a quarter of a mile away. "Found it!" panted Mark; "a nest with young ones. Chance if there are any eggs for Master Rayburn." He leaned back to examine the place. "Can't get up there," he muttered at last; "but it would be easy to get down from the top. I could do it, but--" He took off his cap, and gave his brown hair a vicious scratch, for there were other obstacles in the way. It would be easy to wade across the river; easy to make his way along the other side to where the cliff sloped, five hundred yards lower down the stream. From there he could reach the high down, which was broken off short to form the cliff, and walk along the edge till he was exactly over the nest, and then descend. Those were not obstacles, but trifles. The great difficulty was moral. That great mass of limestone was on the Darley estate, and for a few minutes, the lad felt as if he must give it up. But obstacles only spurred him on to action, and he cried to himself, petulantly: "Is it theirs? Who are they, to claim an open wild place like that? They'll be saying next that all Darbyshire belongs to them. It's as much ours as theirs, and, if we had our rights, it would be ours. I shall go, in spite of all the Darleys in the county. Who are they? Piece of rock and moor like that, and they claim it. Let them. I shall not stop away for them." The boy flushed, and ignoring the fact that he was about to commit a trespass, he slipped off shoes and hose, waded straight across the shallow river, and sat down on the other side to dry his feet, and put on hose and shoes again.
