(9) For the internal cohesion of the pack, there must be the equivalent of a recognised table of precedence amongst its members; and this is reconciled with the spirit of emulation, by fighting until each knows his place, followed by complete submission on the part of the inferior. Mr. Th. Roosevelt says of a pack of dogs employed in bear-hunting, “at feeding-time each took whatever his strength permitted, and each paid abject deference to whichever animal was his known superior in prowess.”[46] Mr. W. H. Hudson writes of dogs on cattle-breeding establishments on the pampas, that he presumes “they are very much like feral dogs and wolves in their habits. Their quarrels are incessant; but when a fight begins the head of the pack, as a rule, rushes to the spot,” and tries to part the combatants—not always successfully. “But from the foremost in strength and power down to the weakest there is a gradation of authority; each one knows just how far he can go, which companion he can bully when in a bad temper or wishing to assert himself, and to which he must humbly yield in his turn.”[47] The situation reminds one of a houseful of schoolboys, and of how ontogeny repeats phylogeny. Where political control is very feeble, as in mining camps or backwoods settlements, civilised men revert to the same conditions. Fifty years ago, “all along the frontier between Canada and the United States, every one knew whom he could lick, and who could lick him.”[48] Amongst Australian aborigines, we are told that “precedence counts for very much.”[49] (10) A pack of wolves relies not merely upon running down its prey, but resorts to various stratagems to secure it: as by surrounding it; heading it off from cover; driving it over a precipice; arranging relays of pursuers, who take up the chase when the first begin to flag; setting some to lie in ambush while the rest drive the prey in their direction. Such devices imply intelligent co-operation, some means of communicating ideas, patience and self-control in the interests of the pack and perseverance in carrying out a plan. Failure to co-operate effectually is said to be punished with death. Primitive man, beginning with more brains than a wolf, may be supposed soon to have discovered such arts and to have improved upon them.
