There is no Royal Road to Memory. The cultivation of the memory depends upon the practice along certain scientific lines according to well established psychological laws. Those who hope for a sure "short cut" will be disappointed, for none such exists. As Halleck says: "The student ought not to be disappointed to find that memory is no exception to the rule of improvement by proper methodical and long continued exercise. There is no royal road, no short cut, to the improvement of either mind or muscle. But the student who follows the rules which psychology has laid down may know that he is walking in the shortest path, and not wandering aimlessly about. Using these rules, he will advance much faster than those without chart, compass, or pilot. He will find mnemonics of extremely limited use. Improvement comes by orderly steps. Methods that dazzle at first sight never give solid results."

The student is urged to pay attention to what we have to say in other chapters of the book upon the subjects of attention and association. It is not necessary to state here the particulars that we mention there. The cultivation of the attention is a prerequisite for good memory, and deficiency in this respect means deficiency not only in the field of memory but also in the general field of mental work. In all branches of The New Psychology there is found a constant repetition of the injunction to cultivate the faculty of attention and concentration. Halleck says: "Haziness of perception lies at the root of many a bad memory. If perception is definite, the first step has been taken toward insuring a good memory. If the first impression is vivid, its effect upon the brain cells is more lasting. All persons ought to practice their visualizing power. This will react upon perception and make it more definite. Visualizing will also form a brain habit of remembering things pictorially, and hence more exactly.''

The subject of association must also receive its proper share of attention, for it is by means of association that the stored away records of the memory may be recovered or re-collected. As Blackie says: "Nothing helps the mind so much as order and classification. Classes are few, individuals many: to know the class well is to know what is most essential in the character of the individual, and what burdens the memory least to retain." And as Halleck says regarding the subject of association by relation: "Whenever we can discover any relation between facts, it is far easier to remember them. The intelligent law of memory may be summed up in these words: Endeavor to link by some thought relation each new mental acquisition to an old one. Bind new facts to other facts by relations of similarity, cause and effect, whole and part, or by any logical relation, and we shall find that when an idea occurs to us, a host of related ideas will flow into the mind. If we wish to prepare a speech or write an article on any subject, pertinent illustrations will suggest themselves. The person whose memory is merely contiguous will wonder how we think of them."
