Evinronmentalist try to save dolphins

Environmentalists are beginning another desperate effort in a few hours to save a school of dolphins stranded for days off New York's Long Island coast. Several dolphins from the group of twenty or so have already been guided out to sea, but some have died and a number remain trapped in the shallow waters of a cove. Environmentalists will use high frequency sound generators and a flotilla of small boats to try to herd the dolphins to safety. The creatures are growing increasingly weak and it's thought today's rescue effort may be a last chance to save them.
