216 pp. By the author of Our Hearts Were Young and Gay. Illustrated by Mircea Vasiliu. This is, happily, another of Emily Kimbrough's delightful travel books, this time about a two-week cruise on a converted barge on the river Shannon, in Ireland. As the eight passengers hurried to board a Killaloe, the owner commented, "Time enough." And so there was, for what amounted to a suspension of time with no thought of clocks or calendars, just the quiet, constant beauty of the passing Irish scenery.
