Glenarvan, with Robert at his side, galloped along without saying a word. His bold, determined nature made it impossible to take failure quietly. His heart throbbed as if it would burst, and his head was burning. Paganel, excited by the difficulty, was turning over and over the words of the document, and trying to discover some new meaning. Thalcave was perfectly silent, and left Thaouka to lead the way. The Major, always confident, remained firm at his post, like a man on whom discouragement takes no hold. Tom Austin and his two sailors shared the dejection of their master. A timid rabbit happened to run across their path, and the superstitious men looked at each other in dismay.

“A bad omen,” said Wilson.

“Yes, in the Highlands,” repeated Mulrady.

“What’s bad in the Highlands is not better here,” returned Wilson sententiously.

Toward noon they had crossed the Sierra, and descended into the undulating plains which extend to the sea. Limpid RIOS intersected these plains, and lost themselves among the tall grasses. The ground had once more become a dead level, the last mountains of the Pampas were passed, and a long carpet of verdure unrolled itself over the monotonous prairie beneath the horses’ tread.

Hitherto the weather had been fine, but to-day the sky presented anything but a reassuring appearance. The heavy vapors, generated by the high temperature of the preceding days, hung in thick clouds, which ere long would empty themselves in torrents of rain. Moreover, the vicinity of the Atlantic, and the prevailing west wind, made the climate of this district particularly damp. This was evident by the fertility and abundance of the pasture and its dark color. However, the clouds remained unbroken for the present, and in the evening, after a brisk gallop of forty miles, the horses stopped on the brink of deep CANADAS, immense natural trenches filled with water. No shelter was near, and ponchos had to serve both for tents and coverlets as each man lay down and fell asleep beneath the threatening sky.

Next day the presence of water became still more sensibly felt; it seemed to exude from every pore of the ground. Soon large ponds, some just beginning to form, and some already deep, lay across the route to the east. As long as they had only to deal with lagoons, circumscribed pieces of water unencumbered with aquatic plants, the horses could get through well enough, but when they encountered moving sloughs called PENTANOS, it was harder work. Tall grass blocked them up, and they were involved in the peril before they were aware.

These bogs had already proved fatal to more than one living thing, for Robert, who had got a good bit ahead of the party, came rushing back at full gallop, calling out:

“Monsieur Paganel, Monsieur Paganel, a forest of horns.”

“What!” exclaimed the geographer; “you have found a forest of horns?”
