Lincoln and his intimate political advisers were not slow to note the signs of danger; and the remedy devised threw upon him the burden of a new responsibility.

It was decided in the councils of the Republican leaders that Lincoln should challenge Douglas to joint public debate.
The challenge was sent by Lincoln on July 24; Douglas proposed that they should meet at the towns of Ottawa, Freeport, Jonesboro, Charleston, Galesburg, Quincy, and Alton, each speaker alternately to open and close the discussion; Douglas to speak one hour at Ottawa, Lincoln to reply for an hour and a half, and Douglas to make a half hour's rejoinder.

In like manner Lincoln should open and close at Freeport, and so on alternately.

Lincoln's note of July 31 accepted the proposal as made.

"Although by the terms," he wrote, "as you propose, you take four openings and closes to my three, I accede and thus close the arrangement." Meanwhile each of the speakers made independent appointments for other days and places than these seven; and in the heat and dust of midsummer traveled and addressed the people for a period of about one hundred days, frequently making the necessary journeys by night, and often speaking two and sometimes even three times in a single day.
