Informants agreed that the Agaidika formed a unified band under Tendoy. No other chiefs were named, although there were said to be a number of minor leaders. Tendoy acted as leader in such communal pursuits as the making of salmon traps or in the annual buffalo hunt. Informants said that he called a council of leading men of the band when any decision affecting the whole group was to be made, and the results were announced to the people by a man who held the office of "announcer." Councils might be held before the salmon season and the buffalo hunt or to plot strategy when on the buffalo hunt.
While the Lemhi Shoshone intermarried with other Shoshone and with Bannock, there was a clear-cut geographical separation between them and the above groups. Some Shoshone wintered in Montana on the other side of the Divide, but they were generally considered to be of the Lemhi band. To the west was the Sawtooth Range and the Tukurika. Although the Tukurika had some contact with the Lemhi people, there were considerable cultural differences between them, owing to the proximity of Plains Indian tribes to the Agaidika and to the different subsistent cycles of the two groups. North of the Lemhi country was the land of the Flathead; to the south the arid Snake River plains intervened between them and the Fort Hall plains population. The Lemhi Shoshone were by no means isolated, but there was considerably less overlapping of activities than in southeastern Idaho.
Winter was usually spent in the valley of the Lemhi River in the area between the modern town of Salmon and the old Mormon post of Fort Lemhi. One informant said that the population was distributed in villages of about a dozen buffalo-hide tipis, each village having a leader. During the winter the population subsisted upon dried stores of berries, roots, and the meat of buffalo and other game. The Lemhi Valley was secure from enemy attack in the winter, for the Blackfoot concentrated their attention on the Bannock encampments on the Snake River.
Other Shoshone were said to have wintered occasionally on the Beaverhead River in Montana. Steward notes that "possibly a few families lived in the vicinity of Dillon, Montana" (1938, p. 188). He lists a large winter camp of some forty families named "Unauvump," which was situated along Red Rock Creek from Lima, Montana, to Red Rock Lake (ibid.). Steward notes that this name refers to the "locomotive" and thus to the Union Pacific Railroad, which follows the Beaverhead River. We obtained the same name, but our informant thought it was merely a place name and not a camp site. Also the site was a short distance up the Beaverhead River from Dillon, Montana. In any case, the reference to the locomotive established the recency of the name. In view of the Blackfoot incursions in that area it is doubtful whether the camp on Red Rock Creek much pre-dated the treaty. However, Bannock and Shoshone buffalo-hunting parties were frequently forced to spend the winter in Montana, although the exact location of these camps is not known.
When winter ended, the Lemhi population did not move far afield in search of subsistence, but hunted and awaited the spring salmon run in April. The Indians fished with harpoons, set basketry traps, and made fish weirs. Most fishing was done in the Lemhi River, but some families fished in the Pahsimeroi River, an affluent of the Salmon River which flowed west of and parallel to the Lemhi. Some fishing took place on the main stream of the Salmon River below its confluence with the Lemhi, but only harpooning was effective owing to the depth of the water.
The weirs were put in the water each spring and dismantled in the fall and stored. Certain men were considered especially proficient in the construction and operation of fish weirs and assumed supervision over the operation.
When the salmon runs had ended, many of the Lemhi people went to Camas Prairie. Some preferred to dig roots in the Lemhi country or to hunt deer in the ranges on either side of the valley. These hunting groups were quite small and usually numbered only two to four tipis. The sojourn on Camas Prairie lasted only about a month and the Lemhi people returned for the summer-fall salmon run. When this was over at the end of August, preparations were made for the trip to the buffalo country.
At least three horses were required for the buffalo hunt: one for the hunter, another for his wife, and a third for packing purposes. Even this number was inadequate, since children also needed mounts and one pack horse was not enough to transport a good take of meat and hides. Also, the hunter should preferably have a specially trained buffalo horse, which he would ride only while the buffalo herd was being chased. While the Lemhi were richer in horses than were most Shoshone, some people were forced to stay at home. These hunted game in the mountains of the Lemhi region and adjoining areas on the Montana side of the Divide and depended to some extent on the largesse of the returning buffalo party.
The buffalo hunters crossed the Divide through Lemhi Pass to the Beaverhead River and went out to the hunting grounds along the previously described routes. Our informants had no recollection of alliances with other Shoshone or with other tribes on the buffalo hunt except for one who said that the Lemhi Shoshone hunted with Nez Percé parties after an earlier period of hostility. At this earlier time the Nez Percé and the Flathead were said to have been enemies of the Lemhi people. Lemhi informants claimed that the buffalo parties usually succeeded in reaching winter quarters on the Lemhi River before the snows closed the passes. In view of Lewis and Clark's information and our data from Fort Hall, however, it might be supposed that they were often forced to remain in Montana for the winter.
