THE CHAIRMAN, introducing the lecturer, said it gave him very great pleasure to welcome a visitor from a great and friendly country. Norway was only a small country speaking from the point of view of the number of its nationals, but it was a great country judged by the character of its people, which was surely the way to judge the stature of a country. Welcoming the lecturer personally, and referring to his history and achievements, the Chairman said that from 1949 to 1954 Mr. Arild had acted as Assistant Chief Engineer in the Bridge Division of the Norwegian State Railways, and since 1954 he had been the Director of that Division.
