The governor could not go with them again for two days on account of business; but full of their swimming, they looked in the old bookcase, and found a book in which there were instructions, and among other things they read that the frog was the best model. Out they ran to look for a frog; but as it was sunny there were none visible, till Mark remembered there was generally one where the ivy of the garden wall had spread over the ground in the corner. In that cool place they found one, and Bevis picked it up. The frog was cold to the touch even in the summer day, so they put it on a cabbage-leaf and carried it to the stone trough in the yard. No sooner did it feel the water than the frog struck out and crossed the trough, first in one direction, and then in another, afterwards swimming all round close to the sides, but unable to land, as the stone was to it like a wall. “He kicks,” said Mark, leaning over the trough; “he only kicks; he doesn’t use his arms.” The frog laid out well with his legs, but kept his forelegs, or arms, still, or nearly so. “Now, what’s the good of a frog?” said Bevis; “men don’t swim like that.” “It’s very stupid,” said Mark; “he’s no model at all.” “Not a bit.” The frog continued to go round the trough much more slowly. “No use watching him.” So they went away, but before they had gone ten yards Bevis ran back. “He can’t get out,” he said; and placing the cabbage-leaf under the frog, he lifted the creature out of the trough and put him on the ground. No sooner was the frog on the ground than he went under the trough in the moist shade there, for the cattle as they drank splashed a good deal over. When they told the governor, he said that what they had noticed was correct, but the frog was a good model in two things nevertheless; first in the way he kicked, and secondly in the way he leaned his chest on the water. But a man had to use his arms so as to balance his body and keep his chin and mouth from going under, besides the assistance they give as oars to go forward. Next morning they went to the bathing-place again. Bevis had now to hold the rail as previously, but when he had got it at arm’s length he was told to kick like the frog.
