Read it through once

In the midst of these whimsical fancies she heard a new strange sound among the leaves. It might be the wind; yet there was scarcely any wind. Sometimes it was a palpitation, sometimes a flutter; sometimes it was a sort of gasp or gurgle. Soon she was certain that the noises came from wild creatures of some kind, the more so when, originating in the boughs overhead, they were followed by the fall of a heavy body upon the ground. Had she been ensconced here under other and more pleasant conditions she would have become alarmed; but, outside humanity, she had at present no fear.
