On December 6 he writes that another Ghost dance had then been in progress for six days, and that the Indians had announced their intention to dance one week in each month until the grass grew, at which time the medicine-men had told them the messiah would come, bringing with him all their dead friends. (_G. D., 13._) This dance, however, was attended by a much smaller number of Indians, and skeptics had already arisen among them to scoff at the new believers. The leaven was working, and only a little shrewd diplomacy was needed to turn the religious scale, as is shown by an extract from a third letter, dated January 10, 1891, from which it would seem that Agent Plumb is a man of practical common sense, as likewise that Esau was not the only one who would sell his birthright for a mess of pottage: Christmas day was the day set for commencing another dance. On learning this, I told the Indians that it was my intention to give them all a big feast and have a general holiday on Christmas, but that I would not give them anything if they intended to dance. I told them they could play all of their usual games, in fact, have a good time, but that dancing was forbidden. I showed them how continued dancing at various Sioux agencies had ended in soldiers being sent to stop them. I stated the case as clearly as I could; the Indians debated it two days, and then reported that while they hoped their dead friends would come back, and believed that dancing would help to bring them, yet they were friends of the government, and friends of the whites, and my friends, and would not hold any more resurrection dances without my consent. Up to this date they have kept their word. I have no hope of breaking up their dances altogether, but I have strong hopes of controlling them. (_G. D., 14._)
