“ Alpha Delta Phi was then the only fraternity in the university, and no doubt much of the similarity which exists between the two fraternities is due to the fact that some of its founders were connected with the older society. The first branch of Beta Theta Pi was, like that of Alpha Delta Phi, established at Cincinnati, and, like it, was transferred to another college. The one fraternity spread East, however, and the other West. ”
