On the other hand, the memory should be specially taxed in youth, since it is then that it is strongest and most tenacious. But in choosing the things that should be committed to memory the utmost care and forethought must be exercised; as lessons well learnt in youth are never forgotten. This precious soil must therefore be cultivated so as to bear as much fruit as possible. If you think how deeply rooted in your memory are those persons whom you knew in the first twelve years of your life, how indelible the impression made upon you by the events of those years, how clear your recollection of most of the things that happened to you then, most of what was told or taught you, it will seem a natural thing to take the susceptibility and tenacity of the mind at that period as the groundwork of education. This may be done by a strict observance of method, and a systematic regulation of the impressions which the mind is to receive.
