How Natural History Should Be Expounded.—Natural history, like the history of the [pg 099] war and victory of moral and intellectual forces in the campaign against anxiety, self-delusion, laziness, superstition, folly, should be so expounded that every reader or listener may be continually aroused to strive after mental and physical health and soundness, after the feeling of joy, and be awakened to the desire to be the heir and continuator of mankind, to an ever nobler adventurous impulse. Hitherto natural history has not found its true language, because the inventive and eloquent artists—who are needed for this purpose—never rid themselves of a secret mistrust of it, and above all never wish to learn from it a thorough lesson. Nevertheless it must be conceded to the English that their scientific manuals for the lower strata of the people have made admirable strides towards that ideal. But then such books are written by their foremost men of learning, full, complete, and inspiring natures, and not, as among us, by mediocre investigators.
