"When a sufficient number of specialists are assembled on a college faculty, the subject of which each knows only a small part of is said to be covered, and the academic department to which they all belong is regarded as fully manned. In ancient Ireland, if legend is to be trusted, there was a tower so high that it took two persons to see the top of it. One would begin at the bottom and look up as far as sight could reach, the other would begin where the first left off, and see the rest of the way."
