 Suspension Bridges of Wire Fencing

��SUSPENSION footbridges have been built by a wire agency in Southern Oregon, to the number of twenty in Jackson County alone, which goes to show their practicability.

The method of construction is simple. Three lengths of fence are used. Two

��total tensile strength of the wires is seventy-five thousand eight hundred and eighty pounds, so that it will safely hold a load of a hundred people. The agency plans to build a one-hundred-foot wagon bridge in the near future along the same lines of construction.

The anchor posts must be well braced and put deep in concrete with long cross-pieces on the bottoms. The ends of the wires are wrapped around the posts and spliced to the wires again, so that there is no danger of their slip- ping, even though the staples may gi\c way.

The bridge shown in the photograph is three hundred and ninety-six feet long; the longest span being two hundred and fifty-six feet. At the highest point it is forty-five feet from the water. The

��A Cheap Way of Preserving Eggs

EGGS may be successfully preserved for many months in a solution of water-glass. One cjuart of water-glass, which may be purchased from any druggist for twenty-five cents, is enough to preserve twenty dozen eggs. Heat ten quarts of water to the boiling point and allow it to cool. Pour the water into a five-gallon earthenware crock, add one quart of water-glass antl mix the two. Place the eggs in this solution as soon as laid, but do not wash them. When the crock is filled to within two inches of the top of the liquid, cover and store in a cool, dry place.
