And this is the sense of the word "grammar" which our inaccurate student detests, and this is the sense of the word which every sensible tutor will maintain. His maxim is "a little, but well"; that is, really know what you say you know: know what you know and what you do not know; get one thing well before you go on to a second; try to ascertain what your words mean; when you read a sentence, picture it before your mind as a whole, take in the truth or information contained in it, express it in your own words, and, if it be important, commit it to the faithful memory. Again, compare one idea with another; adjust truths and facts; form them into one whole, or notice the obstacles which occur in doing so. This is the way to make progress; this is the way to arrive at results; not to swallow knowledge, but (according to the figure sometimes used) to masticate and digest it.
