Must it be confessed! That great child of a Cousin Benedict had hoped for a moment that they would not be able to pass. Such a voyage seemed to him unnecessary. He regretted Alvez's factory and the hut that contained his precious entomologist's box. His chagrin was real, and indeed it was pitiful to see the poor man. Not an insect; no, not one to preserve!

What, then, was his joy when Hercules, "his pupil" after all, brought him a horrible little beast which he had found on a sprig of the tikatika. Singularly enough the brave black seemed a little confused in presenting it to him.

But what exclamations Cousin Benedict uttered when he had brought this insect, which he held between his index finger and his thumb, as near as possible to his short-sighted eyes, which neither glasses nor microscope could now assist.

"Hercules!" he cried, "Hercules! Ah! see what will gain your pardon! Cousin Weldon! Dick! a hexapode, unique in its species, and of African origin! This, at least, they will not dispute with me, and it shall quit me only with my life!"

"It is, then, very precious?" asked Mrs. Weldon.

"Precious!" cried Cousin Benedict. "An insect which is neither a coleopter, nor a neuropteran, nor a hymenopter; which does not belong to any of the ten orders recognized by savants, and which they will be rather tempted to rank in the second section of the arachnides. A sort of spider, which would be a spider if it had eight legs, and is, however, a hexapode, because it has but six. Ah! my friends, Heaven owed me this joy; and at length I shall give my name to a scientific discovery! That insect shall be the 'Hexapodes Benedictus.'"

The enthusiastic savant was so happy—he forgot so many miseries past and to come in riding his favorite hobby—that neither Mrs. Weldon nor Dick Sand grudged him his felicitations.

All this time the perogue moved on the dark waters of the river. The silence of night was only disturbed by the clattering scales of the crocodiles, or the snorting of the hippopotami that sported on the banks.

Then, through the sprigs of the thatch, the moon appeared behind the tops of the trees, throwing its soft light to the interior of the boat.

Suddenly, on the right bank, was heard a distant hubbub, then a dull noise as if giant pumps were working in the dark.
