Rev. Brooke Herford conducted the morning services yesterday with especial reference to the day's being the Day of Prayer set for colleges. Dr. Herford spoke of two kinds of prayer, the prayer of the heart and the prayer of the hands. Besides our inward supplication to God, we should strive by our own deeds to make the University to which we belong better and nobler than when we found it. College men should lead not merely their own private, selfish lives, but they should live in the broader life of the University, and do their best to keep alive and promote all the higher interests which belong to an institution like Harvard.
