The departure of the trading party is a gala occasion and all the people in Cliff Palace join to give it a noisy send-off. It is the first expedition of the spring so a great many men are in the party. As they start down the canyon, each man carries a large pack on his back. Most of a man’s burden consists of the things he will offer in trade when he reaches his destination. Perhaps he has tanned buckskin: the soft white leather has great value in the lands to the south where deer are scarce. He may have the skin of a spotted fawn he choked to death last summer. For ceremonial use the skins must not be pierced by arrows so the animals are caught and choked and such skins are excellent for trading purposes. Also, he may carry a number of large, highly-polished skinning blades made from a banded stone found near the Mesa Verde. This stone is well known over the pueblo region and the blades are highly prized. In addition to his trading materials, a man carries his bow and arrows, a blanket, a small bowl and a little food. He will be able to kill rabbits, squirrels and rats along the way and almost every night he will stop at a friendly village so little food need be carried. A small amount of parched corn, some dried meat and perhaps a little corn meal of a special type is all he will need. The corn meal was prepared last fall for this very purpose. At harvest time the fresh corn was roasted, then ground into meal. This meal was thoroughly toasted and again was ground, this time very fine. The meal is so well cooked that a man need only stir it into a bowl of cold water to have a nourishing drink. The men know all of the streams and springs along the way so there will be no hardships unless they meet enemy people. In two weeks the men begin to return and at the end of the month all are accounted for except a small party which went to the southeast for turquoise and obsidian. They are long overdue and at last the people give them up for lost. It merely means that they encountered a band of nomadic, warlike Indians and perished. Groups of savage hunters sometimes slip into the Pueblo country to prey upon the peaceful farmers and the pressure from these nomadic Indians is being felt more and more. There was a time, many generations ago, when the Mesa Verde people had no outside enemies and their villages were scattered over a vast area. At that time they lived in open pueblos out on the mesa tops and in all the broad valleys. Then nomadic hunting Indians began to drift into the Pueblo country. They raided the small villages, murdered the men, enslaved the women and children and destroyed the crops. In the border regions which were sparsely populated, village after village was destroyed by the raiders. As the pressure increased, the farming people deserted the valleys and the open mesa tops and for the last few generations they have lived in the cliff dwellings which they built in the caves of the Mesa Verde.
