How Lincoln is running the machine in Arkansas.
--The following letter from Lincoln, to a Unionist in Arkansas, is very characteristic:When I fixed a plan for an election in Arkansas I did it in ignorance that your convention was at the same work. Since I learned the latter fact I have been constantly trying to yield my plan to them. I have sent two letters to Gen. Steels and three or four dispatches to you and others, saying that he, (Gen. Steele,) must be master, but that it will probably be best for him to keep the convention on its own plan. Some single mind must be master, else there will be no agreement on anything, and Gen. Steele, commending the military and being on the ground, is the best man to be that master. Even now citizens are telegraphing me to postpone the election to a later day than either affixed by the convention or me. This discord must be silenced.
