first every time you tie your shoes or sign your name. To illustrate the second, I need only ask you to supply the end of this sentence: Columbus discovered America in Speech reveals many of these habits of thought. Certain phrases persist in the mind as habits so that when the phrase is once begun, you proceed habitually with the rest of it. When some one starts "in spite," your mind goes on to think "of"; "more or" calls up "less." When I ask you what word is called up by "black," you reply "white" according to the principles of mental habit. Your mind is arranged in such habitual patterns, and from these examples you readily see that a large part of what you do and think during the course of twenty-four hours is habitual. Twenty years hence you will be even more bound by this overpowering despot.

Our acts our angels are, or good, or ill, Our constant shadows that walk with us still. Since you cannot avoid forming habits, how important it is that you seek to form

those that are useful and desirable. In acquiring them, there are several general principles deducible from the facts of nervous action. The first is, guard the pathways leading to the brain. Nerve tissue is impressible and everything that touches it leaves an ineradicable trace. You can control your habits to some extent, then, by observing caution in permitting things to impress you. Many unfortunate habits of study arise from neglect of this. The habit of using a "pony," for example, arises when one permits oneself to depend upon a group of English words before translating a foreign language.

Nerve pathways should then be guarded with respect to what enters. They should also be guarded with respect to the way things enter. Remember, as the first pathway is cut, subsequent nervous currents will be directed. Consequently if you make a wrong pathway, you will have trouble undoing it.

Another maxim which will obviously prevent undesirable pathways is, go slowly at first. This is an important principle in all learning. If, when trying to learn the date 1453, you carelessly impress it first as 1435, you are likely to have trouble ever after in remembering which is right, 1453 or 1435. As you value your intellectual salvation, then, go slowly in making the first impression and be sure it is right. The next rule is to guard the exits of the nervous currents. That is, watch the movements you make in response to impressions and ideas. This is necessary because the nervous current pushes on past obstructions, through areas in the brain, until it ends in some form of movement, and in finding the way out, it seeks those pathways that have been most frequently travelled. In study, it usually takes the form of movements of speech or writing. You will need to guard this part of the process just as you did the incoming pathway. You must see that the move

ment is made which you wish to build into a habit. In learning the pronunciation of a foreign word, for example, see that your first pronunciation of it is absolutely right. When learning to typewrite see that you always hit the right key during the early trials. The point of exit of a nervous current is the point also where precautions are to be taken in developing good form. The path should be the shortest possible, involving only those muscles that are absolutely necessary. This makes for economy of effort.

The third general principle to be kept in mind is that habits are most easily formed in youth, for this is the period when nerve tissue is most easily impressed and modified. With respect to habit formation, then, you see that youth is the time when emphasis should be laid upon the formation of as many useful habits as possible. The world recognizes this to some extent and society is so organized that the youth of the race are given leisure and protection

so that they may form useful habits. The world asks nothing of you during the next four years except that you develop yourself and form useful habits which will enable you in later life to take your place as a useful and stable member of society.

In addition to the principles just discussed, there are a number of other maxims which have been laid down as guides in the formation of new habits. The first is, make an assertion of will. Vow to yourself that you will form the habit, and keep that resolve ever before you.

The second maxim is, make an emphatic start. Surround yourself with every aid possible. Make it easy at first to perform the act and difficult not to perform it. For example, if you desire to form the habit of arising at six every morning, surround yourself with a number of aids. Buy an alarm clock, and tell some one of your decision. Such efforts at the start "will give your new beginning such a momentum that the temptation to break
