But we are very apt to forget that there are powers and faculties of the mind, equally vigorous, and equally eager to be exercised, that ought also to be provided for. The strength of the will, the power of exercising judgment and discretion, the spirit of enterprise, the love of command, and other such mental impulses, are growing and strengthening every day, in every healthy boy, and they are all clamorous for employment. The instinct that impels them is so strong that they will find employment in some way or other for themselves, unless an occupation is otherwise provided for them. A very large proportion of the acts of mischievousness and wrong which boys commit arise from this cause. Even boys who are bad enough to form a midnight scheme for robbing an orchard, are influenced mainly in perpetrating the deed, not by the pleasure of eating the apples which they expect to obtain by it, but by the pleasure of forming a scheme, of contriving ways and means of surmounting difficulties, of watching against surprises, of braving dangers, of successfully attaining to a desired end over and through a succession of obstacles interposing. This view of the case does not show that such deeds are right; it only shows the true nature of the wrong involved in them, and helps us in discovering and applying the remedy. At least this was Mr. George's view of the case in respect to Waldron, when he heard how often he was getting into difficulty by his adventurous and restless character. He thought that the remedy was, as he expressed it, to _load_ him; that is, to give to the active and enterprising spirit of his mind something to expend his energies upon. It required great tact and discretion, and great knowledge of the habits and characteristics of boyhood, to enable him to do this; but Mr. George possessed these qualities in a high degree. But to return to the story. Mr. George had decided on coming into Scotland from Liverpool by water, because that was the cheapest way of getting into the heart of the country. And here, in order that you may understand the course of Rollo's travels, I must pause to explain the leading geographical features of the country. If you read this explanation carefully, and follow it on the map, you will understand the subsequent narrative much better than you otherwise would do.
