PROBABLY every one of us has received a violent blow in the face from those green doors at the entrance of University. Just as you are rushing in, some one coming out is sure to drive the door between your eyes, - the result of which action is to remind you of required Astronomy. Under ordinary circumstances one comes out under stronger incentive than one goes in, and this additional danger from those deadly doors is enough to discourage all attendance within the portals of University. The College might, at a trifling expense, put glass into the doors, and thus give a man at least a chance to avoid being knocked down before he enters the recitation-room. Another danger which awaits the unfortunate who must enter University descends from above. We refer to the masses of ice and snow which, in ordinary winters, drop from the roof on to the steps, - masses heavy enough to crush the skulls of the whole Freshman class. If the College will place an additional railing on the edge of the roof over the doors, a danger which threatens many valuable lives may easily be removed.
