The Brown Stockings were the recipients of a very agreeable surprise last evening, in the shape of an elegant supper at Sides' restaurant, in commemoration of their well-earned victories over the Chicago club. After the repast, which was replete with all the delicacies of the season, a social hour was passed in congratulatory speeches and songs by the club glee. A substantial token of the club's appreciation of the players' good conduct on and off the field was found upon each plate set apart for the boys who wear the brown.

Also of note, I have to assume that the substantial token of appreciation was cash money.
