them. They were ready to spring into the air and trust to their
swift wings the instant they should detect danger. But they did
not want to fly unless they had to. Besides, they were
curious. They were very curious indeed. They wanted to find out
what that mysterious thing moving through the water towards them
was.

So Mr. and Mrs. Quack watched that thing that looked like a
swimming branch draw nearer and nearer, and the nearer it drew
the more they were puzzled, and the more curious they felt. If it
had been the pond of Paddy the Beaver instead of the Big River,
they would have thought it was Paddy swimming with a branch for
his winter food pile. But Paddy the Beaver was way back in his
own pond, deep in the Green Forest, and they knew it. So this
thing became more and more of a mystery. The nearer it came, the
more nervous and anxious they grew, and at the same time the
greater became their curiosity.

At last Mr. Quack felt that not even to gratify his curiosity
would it be safe to wait longer. He prepared to spring into the
air, knowing that Mrs. Quack would follow him. It was just then
that a funny little sound reached him. It was half snort, half
cough, as if some one had sniffed some water up his nose. There
was something familiar about that sound. Mr. Quack decided to
wait a few minutes longer.

"I'll wait," thought Mr. Quack," until that thing, whatever it
is, comes out of those Black Shadows into the moonlight.
Somehow I have a feeling that we are in no danger."
