With the multitude of other opportunities for education which American life affords, will any large body of men and women attend extension lectures? Will they attend after the novelty is worn off, say during the third year? Will they do anything more than attend? Will they follow courses of study, write essays, and pass examinations? Will the extension system, any better than its decayed predecessor, the old lyceum system, resist the demands of popular audiences and keep itself from slipping out of serious instruction into lively and eloquent entertainment? If the lectures are kept true to their aim of furnishing solid instruction, can they in the long run be paid for? Will it be possible to find in our country clusters of half a dozen towns so grouped and so ready to subscribe to a course of lectures on each day of the week that out of the entire six a living salary can be obtained? Will the new teachers be obliged to confine themselves to the suburbs of large cities, abandoning the scattered dwellers in the country, that portion of our population which is almost the only one at present cut off from tolerable means of culture? If in order to pursue these destitute ones, correspondence methods are employed, in addition to the already approved methods of lecture instruction, will lowering of the standard follow? In England three or four years of extension lectures are counted equivalent to one year of regular study, and a person who has attended extension courses for this time may be admitted without further examination to the second year of university residence. Will anything of the sort be generally attempted here? These grave questions are as yet insusceptible of answer. Affirmative, desirable answers do not seem probable; but experience alone can make the matter plain. Of course the managers are watchfully bearing such questions in mind, and critical watchfulness may greatly aid the better answer and hinder the less desirable. Accordingly anything like a discussion of this class of practical doubts would be inappropriate here. Data for the formation of a confident opinion do not exist. All that can be done by way of warning is to indicate certain large improbabilities, leaving them to be confirmed or thwarted by time and human ingenuity.
