[George Q. Cannon]
... we learned that several of the brethren who have plural families are pursuing an unwise course and bringing their families into Colorado, which action excites the fears of the Prest. of the Stake. He thinks there is danger of an attack being made. It was decided that Brother John Henry Smith should go to San Luis as soon as convenient and correct this; show the brethren the great danger in which they are not only placing themselves, but the whole people, by such conduct, because many of us have told leading men in Colorado that our folks were not living in plural marriage in that State, and if cases of this kind were discovered and brought to the attention of the courts, it might be attended with serious consequences.
