Tubes and Tubular Structures

The present decade will pass down into history notorious for many things good and bad. It will be styled a time of improvement in many ways. It will be remembered as covering the period of the world’s greatest war, but it will also be remembered among all trades appertaining in any way to engineering as the age of progress in the manufacture and manipulation of steel tubing.

The Ornithopter

There is very little probability that any new form of flying device will be originated during the Great War, since the talents and experiments necessary can be more usefully devoted to the improvement of the airplane. The latter has proved so successful that there is small prospect that any rival could develop to a comparable degree of efficiency in the present environment.
