“Then you will be gobbled up by either one alligator or one shark,” he replied; “for though the water is brackish, the alligators come down here to pick up any morsels they can find, and the sharks come for the same purpose.”

I thanked him for his warning, but still felt rather doubtful if he was right. To convince me, he procured two pieces of offal, which he carried at the end of his stick, and accompanied me down to the landing-place, a rough stone pier which projected into the lake. Taking a piece, he jerked it some distance into the water, when in an instant a huge pair of jaws with rows of sharp teeth rose above the surface and snapped it up. He then took the other piece and threw it in an opposite direction, when just as it reached the water another pair of jaws, the lower part of silvery-whiteness, rose above the water, and the meat was gone.

“You see, my young friend, you can have your choice,” he said; “but I don’t think you will wish just now to bathe in this place.”

I assured him I did not; and he having lighted a big meerschaum pipe which he drew from his pocket, we returned to the fort. I inquired whether he was the surgeon of the forces stationed there.

“Such an occupation would not suit my fancy,” he answered, shrugging his shoulders; “though, while I am here, I willingly cooper up those who require my services. I am a traveller and naturalist, desirous of seeing the country and the strange creatures it contains, and in search of adventures, which I may perhaps some day narrate for the enlightenment of the world.”

I, of course, replied that I hoped he would do so, as I should like to read the work of one who had rendered me so essential a service; and I added that I felt deeply grateful to him, as he had certainly saved my life by preventing me from venturing into the water.

“It was at no great cost to myself,” he answered; “but I should have grieved to see one so young swallowed by a saurian, and who is, at all events, capable of becoming food for powder, if for nothing else—eh? What do you say, my young friend?”

Somewhat uncertain whether or not the doctor was quizzing me, I replied that I hoped I might some day become fit for a better fate than he suggested.

“Yet such has been the lot of many a fine man with a head on his shoulders, who has run it into a quarrel not his own,” he observed. “I know what war is—a horrible, detestable affair at the best. Take my advice: Have nothing to do with it. Both parties now striving for the mastery are savages. You will find that out before long—though do not tell the commandant what I say, or he may chance to order me out to be shot, as a traitor to the cause of liberty. Bah!—there is only liberty where good laws exist, which all obey! Here, the only laws obeyed are those administered at the point of the bayonet. But don’t repeat this,” he added, putting his finger to his lips and turning away.

After parting from the doctor, I returned to the house of the commandant, whom, with my uncle, I found at breakfast. I at once made inquiries about my friend of the morning.
