Chapter XVIII

At last the night arrived for the gold quest. The guests had gone. Roldan, Adan, and Rafael were alone on their side of the great house. They waited, kicking their heels together with leashed impatience, until eleven o'clock. The family and servants of Casa Encarnacion went to bed at ten o'clock, but it was the custom of Don Tiburcio to go the rounds a half or three quarters of an hour later and see that his strict laws were as strictly obeyed. To-night, when he opened the doors of the three young dons in succession, heels were still, and breathing was as monotonous as his own would be an hour later. At eleven the boys dressed and swung from their windows, not daring to leave by the courtyard. Nor did they dare go to the corral and abstract three horses. Much to their distaste, for there was nothing the Californian hated so much as to travel on two legs, they were obliged to walk the miles between the Casa and the hills. But their legs were young and their brains eager; in little over an hour they were in sight of the Mission.

It looked very white and ghostly in the pale blaze of the moon, a huge mass, full of prayer and discontent. Close beside it, but without the walls, the Indians slept in the rancheria, quiescent enough, for they had no Anastacio. At midnight the great bells in the tower had rung out, filling the valley with their sweet silver clamour; but as the boys approached and skirted the wall, some distance to the right, the Mission might have been as lifeless as it is this year, in its desertion and decay.

The hills were a mile behind. The Mission, like all of its kind, stood on a broad open, that no hostile tribe might approach unseen. Cows and horses lay in their first heavy sleep, their breathing hardly ruffling the profound stillness. So great an air of repose did the silent walls and sleeping beasts give to the landscape that the boys felt the quiet of the night as they had not done in the other valley, and drew closer together, almost holding their breath lest the priests might hear it. A quarter of an hour later they were among the hills and standing before the aperture whose secrets were known only to Padre Osuna. They glanced at each other out of the corners of their eyes. Brave as they were, they did not altogether like the idea of a possible encounter with a rattlesnake or a bear in the dark and narrow confines of a cave. And if there should be another earthquake! However, they had not come to turn back, and Roldan pushed boldly in, the others following close.

For a time their way lay along a narrow passage. They had made two abrupt turns before they dared to light the lantern they had brought. When Rafael did, it revealed nothing but earthy walls and the imprint of feet on the ground. After a little, however, the passage suddenly widened, and it was Adan who uttered the first exclamation of surprise. It was, indeed, a hoarse gurgle. The walls were veined with what appeared to be irregular
