In the selection of specimens from this copious material, Maitland displayed a felicitous strategy the aim of which was to exhibit, as rapidly as might be, the range and versatility of the Society's operations. A sequence of volumes illustrating any one department of law would fatigue attention, warn off subscribers and fail to make the desired impression on the general historical public. It was better to begin upon several different types of record than to work one vein without intermission; better for the cause of science, and a course more likely to bring forward good contributors as well as to stimulate public interest in the undertaking. With a general editor less perfectly equipped such a scheme might have been hazardous; but Maitland was master of the whole field and could be trusted not to fail in proportion and perspective. In swift succession the members of the Selden Society received volumes illustrating Pleas of the Crown, Pleas of Manorial Courts, Civil Pleas, manorial formularies, the Leet jurisdiction of Norwich, Admiralty Pleas; then an edition of the _Mirror of Justice_ followed by a volume on _Bracton and Azo_. Of these first eight volumes Maitland wrote four and contributed a brilliant introduction to a fifth--the edition of the _Mirror_, executed by his pupil and friend Mr W. J. Whittaker. It was an astonishing performance; even had the work been spread over twelve years of robust energy it would still have been astonishing. It was accomplished in half that time by a busy, delicate, University Professor who apart from statutory Professorial lectures was simultaneously engaged in writing the classical _History of English Law_.
