“ Indeed, this keen participation in the nature and delights of the young was the secret of his success during the Kafiristan exploration. It was the touchstone of his sympathy with the various barbaric tribes with whom he had to come in contact, and whose nature he did not require to learn, for he had already sounded all that was human in its touching variety. Love and sympathy for man as man, could alone give this knowledge and furnish this magic key to hearts in wilds unknown. No human system of mental training could ever do it. ”
