His example was doubtless infectious, for the Ann Arbor citizens continued their tree-planting efforts around the outside of the Campus in the spring of 1858, while a group of sixty trees presented to the University were set out inside. The seniors of '58 left a memorial in the shape of concentric rings of maples about a native oak in the center of the Campus, one of the few survivals of the original forest growth, which has since become known as the Tappan Oak, and is now marked by a tablet on a boulder placed there in later years by '58. Many of these maples still survive, though all traces of the circles are lost. The juniors also set out another group further to the east, while Professor Fasquelle planted a number of evergreens east of the north wing to balance a similar group of Professor White's at the south. The maples outside the walk on State Street were also the gift of Professor White and were balanced by a similar row of elms on the inside, given by the Faculty of the Literary Department. This general interest in Campus improvement did not escape the Regents and successive appropriations, though comparatively small, continued the work until Michigan now has, in the words of the father of the movement, written forty-six years after his work was undertaken, "one of the most beautiful academic groves to be seen in any part of the world,"--a monument to him and to the students of his time. The development of the building program, if a thing so haphazard can go by that name, was less fortunate for the University. Only in very recent years has there been any appreciation of the need of some degree of uniformity and planning for the future. Many of the present buildings have been evolved, as the needs of the University grew, rather than planned, while others have been built to suit the tastes of certain officers, or the special needs of the departments concerned, with no reference to the larger unity which has come to be recognized as so necessary in any group of buildings. Some of the oldest buildings have gone; in particular the two residences on the north, which became the old Dental College and the Homeopathic School in their last incarnations, while the picturesque old Medical Building followed them a few years later. The two on the south still survive; the President's House, though often remodeled, still retains its old lines, but the adjacent building, now known as the Old Engineering Building and used largely for instruction in modern languages in the Engineering College, has lost all semblance of its former character.
