Armored Truck Which Swam Hudson to Be Shown in Washington.

The amphibious tank which traveled 25 miles an hour on Riverside Drive on Tuesday, then climbed 100 feet up the slope of the Palisades and swam across the Hudson River under its own power, will be demonstrated in Washington within the next few weeks, according to Walter Christie, the inventor.  Army and Navy officers as well as members of the Senate and House Committees on Military affairs will be spectators.  The tank carries a field gun, crew, with supplies and shelter and ammunition enough for a day's firing.

Mr. Christie said yesterday that he is now devoting himself to the perfection of a device for the conversion of a motor truck into a caterpillar tractor in a few minutes.  He said that a truck manufacturing company was interested in his invention and that he would soon give a public demonstration.

The device, he said, is a caterpillar attachment compact enough to be carried by a motor truck for use on very bad roads and to get trucks out of ditches and ruts.
