Those, again, who will join with children and help them in their sports, will learn by this mode to understand the feelings and interests of childhood; while, at the same time, they secure a degree of confidence and affection which can not be gained so easily in any other way. And it is to be regretted that parents so often relinquish this most powerful mode of influence to domestics and playmates, who often use it in the most pernicious manner. In joining in such sports, older persons should never yield entirely the attitude of superiors, or allow disrespectful manners or address. And respectful deportment is never more cheerfully accorded, than in seasons when young hearts are pleased and made grateful by having their tastes and enjoyments so efficiently promoted. Next to the want of all government, the two most fruitful sources of evil to children are, _unsteadiness_ in government and _over-government_. Most of the cases in which the children of sensible and conscientious parents turn out badly, result from one or the other of these causes. In cases of unsteady government, either one parent is very strict, severe, and unbending, and the other excessively indulgent, or else the parents are sometimes very strict and decided, and at other times allow disobedience to go unpunished. In such cases, children, never knowing exactly when they can escape with impunity, are constantly tempted to make the trial. The bad effects of this can be better appreciated by reference to one important principle of the mind. It is found to be universally true that, when any object of desire is put entirely beyond the reach of hope or expectation, the mind very soon ceases to long for it, and turns to other objects of pursuit. But so long as the mind is hoping for some good, and making efforts to obtain it, any opposition excites irritable feelings. Let the object be put entirely beyond all hope, and this irritation soon ceases. In consequence of this principle, those children who are under the care of persons of steady and decided government know that, whenever a thing is forbidden or denied, it is out of the reach of hope; the desire, therefore, soon ceases, and they turn to other objects. But the children of undecided, or of over-indulgent parents, never enjoy this preserving aid. When a thing is denied, they never know but either coaxing may win it, or disobedience secure it without any penalty, and so they are kept in that state of hope and anxiety which produces irritation and tempts to insubordination. The children of very indulgent parents, and of those who are undecided and unsteady in government, are very apt to become fretful, irritable, and fractious.
