AN important and heartening announcement is that of the amalgamation of the Institution of Mechanical Engineers and of the Institution of Automobile Engineers, which took place on April 13. During the past fifty years and more, the individual energies of engineers have been dissipated and their corporate authority has been lessened by the multiplicity of engineering institutions which grew up to satisfy the needs of specialist branches of the profession. Though many of these younger institutions have done excellent work in furthering the development of particular sections of engineering, which it was felt at the time of their foundation were neglected by the senior institutions, there is no doubt that the engineering profession has been split by conflicting allegiances, and that it has been more difficult for engineers to speak with one voice on important issues. The Institution of Mechanical Engineers was founded in 1847, so that the amalgamation occurs most happily in the year that the Institution celebrates its centenary. The Institution of Automobile Engineers is forty-one years old.
