Many things which cannot be effected by strength, or by the vulgar way of enterprising, may yet be brought about by some new and untried means. A man of sagacity and penetration, upon encountering a difficulty or two, does not immediately despair; but, if he cannot succeed one way, employs his wit and ingenuity another; and, to avoid or get over an impediment, makes no scruple of stepping out of the path of his forefathers. Since our happiness, next to the regulation of our minds, depends altogether upon our having and enjoying the conveniences of life, why should we stand upon ceremony about the methods of obtaining them, or pay any deference to antiquity upon that score? If almost every age had not exerted itself in some new improvements of its own, we should want a thousand arts, or, at least, many degrees of perfection in every art, which at present we are in possession of. The invention of any thing which is more commodious for the mind or body than what they had before, ought to be embraced readily, and the projector of it distinguished with a suitable encouragement. Such as the use of the compass, for example, from which mankind reaps so much benefit and advantage, and which was not known to former ages. When we follow the steps of those who have gone before us in the old beaten track of life, how do we differ from horses in a team, which are linked to each other by a chain or harness, and move on in a dull heavy pace, to the tune of their leader's bells? But the man who enriches the present fund of knowledge with some new and useful improvement, like a happy adventurer at sea, discovers, as it were, an unknown land, and imports an additional trade into his own country. FABLE XL. [Illustration: THE PORCUPINE AND THE SNAKES.] A Porcupine, wanting to shelter himself, desired a nest of Snakes to give him admittance into their cave. They were prevailed upon, and let him in accordingly; but were so annoyed with his sharp prickly quills, that they soon repented of their easy compliance, and entreated the Porcupine to withdraw, and leave them their hole to themselves. 'No,' says he, 'let them quit the place that don't like it; for my part, I am well enough satisfied as I am.' APPLICATION.
