The simple truth of the matter is that every normal person has an excellent capacity for memory. If it seem poor, inefficient, as inattentive to what is going on round about as a messenger boy reading a dime novel while he loiters on his way, it is because the memory is not given a fair chance. Every time, it is the fault of the owner, not of the memory. The memory needs exercise, training, just as does the hollow chest. It will respond gratefully to treatment, as surely as the lungs to deep breathing. And the response of the mind is swifter, subtler, far more splendid.
