The caption for the photograph on page 1405 in Leslie Roberts' article "Federal report on acid rain draws criticism" (News & Comment, 18 Sept., p. 1404) incorrectly implies that acid rain has damaged spruce trees on Whiteface Mountain. The cause of the spruce decline is not yet known, although air pollution is generally believed to have contributed.
