In particular, therefore: give this student all the mathematics he can absorb, and pass him from arithmetic into geometry, leaving his algebra till later. Give him plenty of grammar, taught inductively. Start him early in the elements of physics and chemistry. And as opposed to this, keep him out of the classes of descriptive botany and zooelogy. Rather let him join exploring parties for the study of plants, stones, and animals. A few pet animals are a valuable adjunct to any school museum. If there be an industrial school or machine shop near at hand, try to get him interested in the way things are made, and encourage him to join in such employments. A false generalization in the wheels of a cart supplies its own corrective very quickly, or in the rigging and sails of a toy boat. Drawing from models is a fine exercise for such a youth, and drawing from life, as soon as he gets a little advanced in the control of his pencil. All this, it is easy to see, trains his impulsive movements into some degree of subjection to the deliberative processes. With this general line of treatment in mind, the details of which the reader will work out in the light of the boy's type, space allows me only two more points before I pass to the sensory scholar. First, in all the teaching of the type of mind now in question, pursue a method which proceeds from the particular to the general. The discussion of pedagogical method with all its ins and outs needs to take cognizance of the differences of students in their type. The motor student should never, in normal cases, be given a general formula and told to work out particular instances; that is too much his tendency already--to approach facts from the point of view of their resemblances. What he needs rather is a sense of the dignity of the single fact, and of the necessity of giving it its separate place, before hastening on to lose it in the flow of a general statement. So whether the teacher have in hand mathematics, grammar, or science, let him disclose the principles only gradually, and always only so far as they are justified by the observations which the boy has been led to make for himself. For the reason that such a method is practically impossible in the descriptive sciences, and some other branches, as taught in the schoolbooks--botany, zooelogy, and, worse than all, history and geography--we should restrict their part in the discipline studies of such a youth. They require simple memory, without observation, and put a premium on hasty and temporary acquisition.
