Although it is only the future that matters, the Centenary of this Society justifies a glance at the past—but what is one to look at? So much has happened.

There is one thing I must say at the outset—that I find it very difficult to believe that it has all happened. Cerainly what has been achieved could not possibly have been foreseen in 1914, and this leads me to something which I believe in very firmly indeed—that is, the futility of planning over a long period. Such planning must be on the most flexible basis possible.
