"What?" demanded his chum.

"I thought I heard a cry from across the river."

Both listened, but nothing came to their ears.

"You must have been mistaken," said the doctor's son, and resumed
his work of picking strawberries.

"No use of picking more," said Snap, a few minutes later. "We'll
be lucky to get over with these. Perhaps we'll drop half of them,
trying to swim."

"Hi, look there!" shouted his companion, and pointed across the field
in the direction of the river.

A flock of sheep had suddenly appeared, some fifteen or twenty in
number. At the head was a large ram, who gazed in wonder at the two
boys in their bathing outfits.

"Say, that ram means business!" ejaculated Snap, an instant later.
"We had better clear out of here."

"Come on, I'm willing," responded the doctor's son, and started
for the stream, carrying the basket of strawberries in one hand.

"Let us go up the stream," went on Snap. "No use of getting too
close to him. I don't like his looks."
