Experimental archaeology has now a definite place in research and the late Paul Johnstone was a pioneer in organizing such experiments especially with boats. In our February issue we published a reconsideration of his experiment, in collaboration with Professor Marstrander, on building a hide boat. We now welcome a discussion by Mr Christensen and Dr Morrison on the recent publication The building and trials of the replica of an ancient boat: the Gokstad faering Part 1. Building the replica by Sean McGrail. 59 pp. 50 figs. Part 2. The sea trials by Eric McKee. 38 pp. 25 figs. National Maritime Museum. Maritime monographs and reports no. 11, 1974. London. Ed.
