It was necessary to proceed with caution; for though the "musquaw" or brown bear will seldom attack a human being unless first assaulted, our friend, if unceremoniously disturbed at night, would probably not be in a good-humour.  Our three well-trained dogs kept at our heels, but the other curs went yelping away through the forest; nor could their masters' voices succeed in calling them back.  We feared, therefore, that they would rouse up the bear, and thus give it time to escape before we could reach its dwelling.
