“Bob! Bob!”
The child remained invisible.
James came up to the captain and the two brothers.
“You haven’t seen Bob, have you?” he asked in a very anxious voice.
“No,” Frank answered.
“I saw him half an hour ago,” Fritz declared; “he was playing with the albatross.”
And all began to call him, turning in every direction.
It was in vain.
Then Fritz and James went to the promontory, climbed the nearest rocks, and looked all over the creek.
Neither child nor bird was there.
