He turned away from the pit with a dull feeling about the heart.
But he would not yet wholly abandon hope.
He conceived the idea that Barney might have been carried into some other part of the berg, and would yet turn up all right and safe.
With this faint hope, Frank went from one passage to another, looking for a descending one.
But none seemed to exist.
In his excitement he did not take the pains to note just where his footsteps were carrying him.
From one passage to another he went in a frantic way.
Suddenly he came to a narrow opening between walls of ice.
A beaten path seemed to lead through this. But this fact Frank did not appear to notice.
He fancied that this passage might lead him into the berg deeper, so he made an effort and squeezed through.
