"I floated around in deep water until my assistant came and secured the snake with a forked stick. It is now in the New York Zoölogical Gardens at the Bronx," concluded the professor.

Jud drew a deep breath. "That reminds me," he said at last, "of a time I once had with a pizen snake when I was a young man. I was hoein' corn up on a side hill in Cornwall when I was about sixteen year old," he continued. "All on a sudden I heard a rattlin' an' down the hill in one of the furrows came rollin' a monstrous hoop-snake. You know," he explained, "a hoop-snake has an ivory stinger in its tail an' rolls along the ground like a hoop, an' when it strikes it straightens out an' shoots through the air just like a spear."

"I know nothing of the kind," broke in Professor Ditson.

"Well," said Jud, unmoved by the interruption, "when I saw this snake a-rollin' an' a-rattlin' down the hill towards me, I dived under the fence an' put for home, leavin' my hoe stickin' up straight in the furrow. As I slid under the fence," he went on, "I heard a thud, an' looked back just in time to see the old hoop-snake shoot through the air an' stick its stinger deep into the hoe-handle. It sure was a pizen snake, all right," he went on, wagging his head solemnly. "When I came back, an hour or so later, the snake was gone, but that hoe-handle had swelled up pretty nigh as big as my leg."

There was a roar of laughter from Will and Joe, while Jud gazed mournfully out over the water. Professor Ditson was vastly indignant.

"I feel compelled to state," he said emphatically, "that there is no such thing as a hoop-snake and that no snake-venom would have any effect on a hoe-handle."

"Have it your way," said Jud. "It ain't very polite of you to doubt my snake story after I swallowed yours without a word."

At Manaos they left the steamer, and Professor Ditson bought for the party a montaria, a big native boat without a rudder, made of plank and propelled by narrow, pointed paddles. Although Hen and Pinto and the Professor were used to this kind of craft, it did not appeal at all favorably to the Northerners, who were accustomed to the light bark-canoes and broad-bladed paddles of the Northern Indians. Joe was especially scornful.

"This boat worse than a dug out," he objected. "It heavy and clumsy and paddles no good either."

"You'll find it goes all right on these rivers," Professor Ditson reassured him. "We only have a few hundred miles more, anyway before we strike the Trail."
