the secondary causes of the extermination of the buffalo may be catalogued as follows:
(1) man's reckless greed, his wanton destructiveness, and improvidence in not husbanding such resources as come to him from the hand of nature ready made.
(2) the total and utterly inexcusable absence of protective measures and agencies on the part of the national government and of the western states and territories.
