In my own second-year work, in which the students have had all the fitting-school training and the freshman drill besides, I am not infrequently confounded by the inability of students to understand the meaning of words which one uses as a matter of course. The statement that Raleigh secretly married a Lady in Waiting, for instance, reappeared in a note-book in the assertion that Sir Walter ran away with Queen Elizabeth's waiting-maid; and a remark about something which took place at Holland House brought out the unbelievable perversion that the event happened "in a Dutch tavern." Personally I have never discovered how far beyond words of one syllable a lecturer to students may safely go in any assurance that his language will be understood by all the members of his class; but this is one of the things which must be decided if teaching is to be effective.
