A search for an American hiker missing on a tiny Caribbean island since last month was scaled back after police dogs, helicopters and the coast guard failed to turn up any sign of him, the governor of Saba said yesterday. Joel D. Gove, 47, an environmental consultant from Trenton, was last seen Dec. 28 as he hiked toward an abandoned mine on the volcanic island.

A search launched when Gove was reported missing on Dec. 30 was called off after 10 days, Gov. Sydney Sorton said. Trail workers and tourists have been asked to watch for any trace of him. "We don't know what has happened to this gentleman," Sorton said. "We are looking into all possibilities."

Gove's ex-wife and American officials, including an FBI representative, came to the Dutch island after the search began. Saba, a five-square-mile island popular with divers just south of St. Maarten, has a population of about 1,500. - AP
