Animals: Too Many Beavers

If too many bears threaten to spoil the touring in Yellowstone Park too many beavers interfere with travel in Palisades InterstatePark (New York and New Jersey). Two dozen of the nocturnal, Hooveresque rodents dammed one stream so successfully that it backed up and floodeda highway. Major W. A. Welch, the park manager and engineer, set traps, caught the entire offending colony, saved State money by transferring the animals last week to a swamp which he wanted transformed into a lake to improve the scenery.
