At that moment there was a heavy splash as a large silvery fish flung itself completely out of the water and then fell back, while the noise it made startled a covey of ducks, which went fluttering and paddling up stream. "Must be inhabitants here, I should say," exclaimed the American, shading his eyes with his hand. "A bit shut in and shady, but all the better in a tropical country: why, it's lovely. Here, gentlemen, I'm getting a bit tired of being cramped up in a boat. I vote we call this Golden Valley and come and live here for a year or two." "To hunt for the Golden City?" said Brace mischievously. "Oh, no," said Briscoe quietly; "this place makes me feel as if I didn't want to hunt for anything, only to knock myself up a hut, or to find a sort of cave up on one of these shelves, and then just go on living like. Why, it's a ready-made Paradise, and we seem to have pretty nearly got beyond the reach of the flood." "Then let's lie up here," said the captain, "and set your Dan to work. It is very beautiful, but it will be better after we've had a bit of something to eat." CHAPTER THIRTY FIVE. NIGHT IN THE CANON. There was a murmur of approval all through the boat, and soon after the lines were made fast ashore, and Brace was one of the first to climb up to the level shelf the captain had marked out. From here he could command a view of the river banks for quite a mile before the narrow canon curved, and they loveliness of the place was so surpassing that he stood speechless, forgetting everything in the beauty of the scene, green and golden in the level rays of the sun, with every here and there the shadows deepening into violet. Brace started as if out of a waking dream as a hand was laid upon his shoulder, and he turned to face Briscoe. "What can you see?" said the latter, in a low voice. For answer Brace simply pointed along the canon, and the American took a long look in silence before venturing to speak again. "Yes," he said slowly; "very pretty, but I'm not a very sentimental man. One minute I feel as if I should like to live here, and the next I feel certain it would be too dull. Can't see any more signs of the Indians, can you?" "No," said Brace. "What sort of a place have you got here? Oh! that's all right; quite a cavern there. Do splendidly for Dan and the boys to make the fire in, out of sight, for we don't want it to bring down strangers upon us. Let's have a look." Brace had not noticed any cavern, but now his attention was drawn to it he saw at the back of the shelf that there was a broad rift in the cliff, some ten or a dozen feet wide and seven or eight high, while upon entering it was to find that they could look forward into darkness of unknown depth, while the roof seemed to rise as it receded. "Looks big," said Briscoe, raising his gun as if to fire.
