Affairs in Illinois.
--A letter from a reader of the Sun, at Mount Pleasant, Union county, Illinois, says this season has been one of the sickliest ever known in that section of the State. In no less than five counties the circuit courts had to adjourn over on account of the general prevalence of sickness. Of the crops, the writer remarks that cotton is turning out about eight hundred pounds to the acre in the seed, and the corn forty bushels to the acre, while the tobacco crop is quite small. Prices are: For tobacco, ten cents per pound; cotton, nine cents in the seed and thirty-eight cents in the lint; wheat, two dollars and twenty-five cents per bushel; corn, sixty cents; pork, fifteen dollars per one hundred pounds; beef, ten to twelve cents per pound, and flour twelve dollars a barrel.
