"The work of the lost people!" said the chief, endeavouring to displace some stones from their artificial bed, but which resisted all his efforts.

"This does look as though civilized people had lived here," said the trapper. "This wall has been built to confine the water to its channel, in times of heavy rains, so that it shall not inundate the plain. Probably, these strange fruit trees are the seed of some brought here from other regions by those builders which have planted themselves, flourished, grown, and outlived all the changes that time has wrought."

"My forefathers have a tradition that it was a strong people that built these things, more cunning and powerful than the white man, until the Great Spirit became angry with them, and then they dried up like the grass on the prairie when there is no rain; for, who is there that dare brave him without being consumed with his anger?"

"We will go down to that copse yonder," said the trapper. "If I am not mistaken, there is more than trees there."

"An herd of deer, perhaps," said the chief, preparing his bow for action.

"I think not, unless deer are grey, and of inordinate proportions. From here, it looks like piles of stone. Perhaps more of the work of those who curbed these waters," said Howe.

As they drew near, large blocks of stone, squared and smoothly hewn, lay in their path, and covered the ground around them. Crossing over these, they came to a range of grey stone, that had the appearance of once having been a high building, but which was now thrown down, and tumbled into a shapeless mass. To the right of these stones they saw a small square enclosure, strongly built of grey hewn stone, and the joints fitted with a precision that would do credit to a stone-cutter in our day. Every layer was strongly cemented with a composition that seemed to have amalgamated with the stone, for on striking it with the tomahawk, it did not even chip off, but gave back a ringing sound, like the hardest granite. One thing they noticed was very singular, both in the wall of this enclosure and in that by the river. The cement in which it was laid was much darker than the stone, being almost black, while the fallen building which they first came to was laid in a white cement, quite like, in appearance, our own.

Going around this enclosure they were astonished to find that they were in a city in ruins. Before them lay whole squares of shapeless masses, overgrown with trees and shrubs, but the perfect regularity of the form and finish of the blocks of stone, of which they had been composed, with the mortar in which they had been laid still clinging to them, were sufficient to convince them that they had once been buildings of more than ordinary proportions and finish.

They attempted to force their way over this irregular pile of rubbish; but found it a dangerous undertaking, as the blocks on which they placed their feet yielded to their weight, and slipping from their beds, threw them on the sharp edges of the stones—a proceeding they did not at all relish. After receiving three or four such falls apiece, and preferring the longer route as the safest, they started to go around it, in order to investigate the forest beyond as they caught a glimpse of some buildings still standing, through the leaves, that hid the main structure from sight.

Taking their way around the western side of the obstruction, they came to a long wide avenue, on which nothing but moss and small dwarf shrubs grew, and which was perfectly smooth and level.
