“No, my Lord,” said the lad in a firm tone, “and moreover, beside you I am afraid of nothing.”

“So much the better. These AGUARAS are not very formidable either; and if it were not for their number I should not give them a thought.”

“Never mind; we are all well armed; let them come.”

“We’ll certainly give them a warm reception,” rejoined Glenarvan.

His Lordship only spoke thus to reassure the child, for a secret terror filled him at the sight of this legion of bloodthirsty animals let loose on them at midnight.

There might possibly be some hundreds, and what could three men do, even armed to the teeth, against such a multitude?

As soon as Thalcave said the word AGUARA, Glenarvan knew that he meant the red wolf, for this is the name given to it by the Pampas Indians. This voracious animal, called by naturalists the Canis jubatus, is in shape like a large dog, and has the head of a fox. Its fur is a reddish-cinnamon color, and there is a black mane all down the back. It is a strong, nimble animal, generally inhabiting marshy places, and pursuing aquatic animals by swimming, prowling about by night and sleeping during the day. Its attacks are particularly dreaded at the ESTANCIAS, or sheep stations, as it often commits considerable ravages, carrying off the finest of the flock. Singly, the AGUARA is not much to be feared; but they generally go in immense packs, and one had better have to deal with a jaguar or cougar than with them.

Both from the noise of the howling and the multitude of shadows leaping about, Glenarvan had a pretty good idea of the number of the wolves, and he knew they had scented a good meal of human flesh or horse flesh, and none of them would go back to their dens without a share. It was certainly a very alarming situation to be in.

The assailants were gradually drawing closer. The horses displayed signs of the liveliest terror, with the exception of Thaouka, who stamped his foot, and tried to break loose and get out. His master could only calm him by keeping up a low, continuous whistle.

Glenarvan and Robert had posted themselves so as to defend the opening of the RAMADA. They were just going to fire into the nearest ranks of the wolves when Thalcave lowered their weapons.
