'IT should suffice each of us to know that, if we have laboured with purity of purpose in any good cause, we must have contributed to its success; that the degree in which we have contributed is a matter of infinitely small concern; and, still more, that the consciousness of having so contributed, however obscurely and unnoticed, should be our sufficient if our sole reward. Let us cherish this faith: it is a duty.'

W. R. Greg.
