The six groups here enumerated--Dakota, Mandan, Pawnee, Maskoki, Algonquin, Iroquois--made up the great body of the aborigines of North America who at the time of the Discovery lived in the lower status of barbarism. All made pottery of various degrees of rudeness. Their tools and weapons were of the Neolithic type,--stone either polished or accurately and artistically chipped. For the most part they lived in stockaded villages, and cultivated maize, beans, pumpkins, squashes, sunflowers, and tobacco. They depended for subsistence partly upon such vegetable products, partly upon hunting and fishing, the women generally attending to the horticulture, the men to the chase. _Horticulture_ is an appropriate designation for this stage in which the ground is merely scratched with stone spades and hoes. It is incipient agriculture, but should be carefully distinguished from the _field agriculture_ in which extensive pieces of land are subdued by the plough. The assistance of domestic animals is needed before such work can be carried far, and it does not appear that there was an approach to field agriculture in any part of pre-Columbian America except Peru, where men were harnessed to the plough, and perhaps occasionally llamas were used in the same way.[52] Where subsistence depended upon rude horticulture eked out by game and fish, it required a large territory to support a sparse population. The great diversity of languages contributed to maintain the isolation of tribes and prevent extensive confederation. Intertribal warfare was perpetual, save now and then for truces of brief duration. Warfare was attended by wholesale massacre. As many prisoners as could be managed were taken home by their captors; in some cases they were adopted into the tribe of the latter as a means of increasing its fighting strength, otherwise they were put to death with lingering torments.[53] There was nothing which afforded the red men such exquisite delight as the spectacle of live human flesh lacerated with stone knives or hissing under the touch of firebrands, and for elaborate ingenuity in devising tortures they have never been equalled.[54] Cannibalism was quite commonly practised.[55] The scalps of slain enemies were always taken, and until they had attained such trophies the young men were not likely to find favour in the eyes of women. The Indian's notions of morality were those that belong to that state of society in which the tribe is the largest well-established political aggregate. Murder without the tribe was meritorious unless it entailed risk of war at an obvious disadvantage; murder within the tribe was either revenged by blood-feud or compounded by a present given to the victim's kinsmen. Such rudimentary _wergild_ was often reckoned in wampum, or strings of beads made of a kind of mussel shell, and put to divers uses, as personal ornament, mnemonic record, and finally money. Religious thought was in the fetishistic or animistic stage,[56] while
