Country Life of June 12th has some remarkable articles on
bridges, notably one by the well-known expert Mr. McColl, which is of more than ephemeral interest. The African World (Salisbury• House, E.C. 2) has published a special African number to commemorate the opening of the Sennar Dam, at 2s. 6d. Those interested in the Sudan and Gezira irrigation
scheme should not miss this number.
