IT was on one of the cool, brilliant days which early June brings to the Narragansett country, that the steamer Eolus pushed out from Wickford Pier on her afternoon trip to Newport. The sky was of a beautiful translucent blue; the sunshine had a silvery rather than a golden radiance. A sea-wind blew up the Western Passage, so cool as to make the passengers on the upper deck glad to draw their wraps about them. The low line of the mainland beyond Conanicut and down to Beaver Tail glittered with a sort of clear-cut radiance, and seemed lifted a little above the water. Candace Arden heard the Captain say that he judged, from the look of things, that there was going to be a change of weather before long.
