A Rope Barometer.

In the office of the Des Moines Register is the best barometer in jlowa. It consists of an ordinary tope attached to the carrier box between the first and fourth floors, making it nearly sixty feet long. This rope is wonderfully sensitive to changes in the atmosphere. At least twenty-four hours before the average rain it begins to tighten by the absorption of moisture. Its predictions nearly always come true.
