Parents go into their office with zeal and good intentions, but without any better knowledge than that which is supplied by the chances of unreasoning custom, impulse, fancy, joined with the suggestions of ignorant nurses and the prejudiced counsel of grandmothers. "Against stupidity the gods themselves are powerless!" We all understand that some kind of preparation is necessary for the merchant, the soldier, the surgeon, or even for making coats and boots; but for the great responsibility of parenthood all preparation is ignored, and people begin the difficult task of rearing children without ever having given a thought to the principles that ought to guide them. How fatal are the results! Who shall say how many early deaths of children and enfeebled constitutions, implying moral and intellectual weakness, are caused by ignorance on the part of parents of the commonest laws of life? Every one can think of illustrations. Our clothing is, in reference to the temperature of the body, merely an equivalent for a certain amount of food, for by diminishing the loss of heat, it diminishes the amount of fuel needful for maintaining heat. Those parents cannot be aware of this who give their children scanty clothing in order to harden them, or who only allow a dawdling walk beside a grown-up person instead of the boisterous play which all young animals require and which would produce warmth. Fathers who pride themselves on taking prizes at cattle-shows for their sheep and pigs are not at all ashamed never to ascertain the best kind of food for feeding children. They do not care if their children are fed with monotonous food, though change of diet is required for the preservation of health. And then as to the intellects of children. Ignorance puts books into their hands full of abstract matter in those early years when the only lessons they are capable of learning are those taught by concrete objects. Not knowing that a child's restless observation and sense of wonder are for a few years its best instructors, parents endeavour to occupy its attention with dull abstractions. It is no wonder that few grown-up people know anything about the beauties and wonders of nature. During those years when the child should have been spelling out nature's primer and pleasurably exercising his powers of observation, grammar, languages, and other abstract studies have occupied most of his attention. Having been "presented with a universal blank of nature's works" he learns to see everything through books, that is, through other men's eyes, and the greater part of his knowledge in after life consists of mere words.
