“ At Harvard, although there are chapters of a few of the fraternities, their influence is insignificant, their place being taken by a group of local societies, some of them class organizations. At Yale, the regular system of fraternities obtains in the engineering or technical department (the Sheffield Scientific School) , but in the classical department the fraternity chapters are called “junior” societies, because they limit their membership to the three upper classes and allow the juniors each year practically to control the chapter affairs. ”
