The next improvement seems to have been the laying out and planting of the College Park, beyond a closed quadrangle behind the present Library Square, in which the students had their recreations. The walled-in court was probably thought sufficient, and most assuredly, until the whole College Park was enclosed, the unfortunate students would by no means have been allowed to wander through it. The lodge, built in 1722 for a porter, at the north-east end, seems to imply that the fencing was then in process.[77] These improvements were followed rapidly by the building of a new Dining Hall, commenced in 1740. A bequest of £1,000 seems to have been the only help required, and in 1745 it was even adorned with some of the portraits which still survive. But in 1758 this Hall was so unsafe that it was taken down, and after dismissing the College bricklayer for his work,[78] the present Hall was set up on the same site, and apparently without change of plan. It must be added, in extenuation of the bricklayer’s conduct, that the ground in that part of the College affords very insecure foundations, as we know from recent experiences. The present building has many great cracks in it, and the new rooms just added have had their foundations sunk to a great depth.[79] What is, however, more interesting as history, is to note that the style of this Hall, not finished till after 1760, is rather the plain and panelled building of the preceding generation. The Theatre (Examination Hall) is decorated in a very different, but not, perhaps, a better style. [Illustration: THE OLD CLOCK TOWER.]
