In the tropical regions, the muscular energy is less, in proportion as the natural fertility of the soil is greater. In colder latitudes muscular energy is increased; and ruder elements, and a more sterile nature, proportion their claims accordingly. In arctic regions no farinaceous food ripens. Sojourners in that climate find, that bread and vegetable diet do not furnish the requisite nutriment; that pure animal food is the only sustenance that will there maintain the tone of the system, imparting a delightful vigor and buoyancy of mind. Strange as it may seem, to conform to this necessity, these dreary countries abound in infinite numbers and varieties of animals, fowls and fishes. The climate favors the drying and preserving of animal food, which is thus prepared to sustain the inhabitants, when nature imprisons the material creation in chains of ice, and wraps herself up in her mantle of snow. Thus, if we survey the whole globe, the food, climate and other circumstances will be found accommodated to the inhabitants; and they, as far as they conform to the organic laws, will be found adapted to their climate and mode of subsistence. In all positions man finds himself called upon, by the clear indications of the organic laws, to take that free and cheerful exercise, which is calculated to develope vigorous muscular, nervous and mental action. The laborer digs, and the hunter chases for subsistence; but finds at the same time health and cheerfulness. The penalty of the violation of this organic law by the indulgence of indolence is debility, enfeebled action, both bodily and mental, dyspepsia with all its horrid train, and finally death. On the other hand, the penalty of over exertion, debauchery, intemperance, and excess of every species, comes in other forms of disease and suffering. These laws, though not so obviously and palpably so, are as invariable and inevitable, as those of attraction, or magnetism; and yet the great mass of our species, even in what we call enlightened and educated countries, do not recognise, and obey them. It is in vain for them, that, from age to age, the same consequences have ensued, as the eternal heralds of the divinity, proclaiming to all people, in all languages, that his laws carry their sanctions with them. One of our most imperious duties, then, is to study these laws, to make ourselves conversant with their bearing upon our pursuit of happiness, that we may conform to them. When we have become acquainted with their universality and resistless power, we shall indulge no puerile hope that we may enjoy the present gratification of infringing them, and then evade the ultimate consequences. We shall as soon calculate to change condition with the tenants of the air and the waters, as expect to divert any one of them from its onward course.
