Not a sound could she hear from her companion, so silently did the latter move away.

After Harriet had gone, Jane called down to her friends that she was going to move from the spot and that they should keep quiet.
The hours passed slowly for Jane.

She was too active to care to sit down calmly and wait when there were things to be done, so Jane decided that she too would explore a little on her own account.

Jane had been gone about an hour when she heard voices directly ahead of her.

She glanced about in quest of a safe hiding place.
