Take note of how long a “not very long mission” is:
In August of 1852, . . . a special conference was held in the old tabernacle on this square. President Heber C. Kimball opened by saying:
“We have come together today, according to previous appointment, to hold a special conference to transact business, a month earlier than usual, inasmuch as there are elders to be selected to go to the missions of the earth, and they want an earlier start than formerly. . . .
“The missions we will call for during this conference are, generally, not to be very long ones; probably from three to seven years will be as long as any man will be absent from his family.”
