ALL‐METAL construction is much to the fore in many countries, in various forms; some engineers still cling to fabric as a covering, relying solely on structural members to take all the stresses, while others prefer taking full advantage of the use of metal throughout, including covering, both to obtain increased durability and to make the skin take its share of the load. It appears probable that, for important machines at least, the latter school is likely to predominate in the future. But it constitutes a much more difficult task if advantages are not to be attained at the expense of other qualities, such as small cost, low weight and ease of repair, to mention but a few. Some firms are working hard in France to arrive at a satisfactory solution of the problem; amongst them, Messrs. Weymann‐Lepère are noteworthy for their recent and strikingly original efforts.
