KANDUM NOTES. - A material deficiency has just been discovered in the strongth of the long joist supporting the floors of the muiu oflices and the floors of the court room and the supervisors' room and other large office on the same floor. The spring of these joists is said by the contraotors and experts to be sufficient to cause the plasteriug on the under side- that is the ceilings of the main offices and of the basement rooms - to crack and fall off. Transverso beams lot into the walls aiul supporting the .joists in the center (with resulting paneled ceilings) are said to be abaolutely necesaary, at an additional cost of from $1,000 to $1,500. The same defect was discovered at Washington, Indiana, the Court House being by the eame architect and substantially from the same plans. An architect ought to better know and botter calcúlate the strength of material: or so it seems to us. If he must choapen lus plans to meet the moneys at the command of his patrons he should rui'uso to do it at such essential points. - The sixth annuat Inter-State Industria! Exposition at Chicago opened on the 4th inat., and will continue until October 19.

If iufelicitous, indisci'eet, or eveu not altogether creditable matrimonial relations, are to be scored against candidates for political honors, Dawson is not the only ambitioua aspirant- either in this or other States - who has need to stand l'roin under. - Bounced : Bishop McCoakry.

C. Joslin, ji Ypsilanti, teil the business nien of that place, and that "plainly, that thoy had not done their duty, and also that if fifteen of them would join hands and work they could drive temperance from Dexter."
