Up-to-date traveling in the author's established footloose manner hops, skips and long jumps from Ireland to England; France to Holland; Denmark, Norway, Sweden and Finland, to Austria, Italy, Spain, Majorca, Portugal; from North Africa to Phoenix, Ariz., and Martha's Vineyard; from Williamsburg to San Francisco and Los Angeles; from the Virgin Islands, the Bahamas and Bermuda to Mexico, Hawaii and Japan. This magpie collection capsules high spots in scenery, living quarters, shopping -- and the alimentary canal; it covers train, steamer, plane, steamship (particularly the new liners) and car travel; it briefs seasons as well as cities and catches the immediate atmosphere in blithe spirits. These bargings around come from Saturday Review columns and give the last minute news on the travel scene in which the useful hints are hidden rather than obtrusive.
