- DISCUSSION ON BO-PEEP AND ARLEY TUNNELS 93 Discussion The Authors presented their Papers with the aid of lantern slides. Mr V. A. M. Robertson remarked on the importance of regular and detailed inspection of tunnels and of permanent way. The Divisional Engineer had had a responsible job in connexion with the Bo-Peep tunnel, as had the inspector, and neither of them hadfailed.
