During the 1865–1866 academic year, Gallaudet responded to criticism from supporters of the oral method in Massachusetts, saying that oral instruction is usually of little value to congenitally deaf children. Gallaudet proposed that a representative of the school be sent to Europe to study the methods employed there, in order to determine which types of instructional methods might be added to those methods already being used successfully at the Columbia Institution and other American schools. Combined enrollment of all levels of instruction, including the collegiate level, exceeded 100 for the first time during this year. There were 25 students enrolled in the college, including students from 14 states. Edward Allen Fay joined the faculty as a professor of history, having learned to sign as a child.
