There are animals that borrow their colour from the neighbouring body, and consequently vary their hue as they happen to change their place. In like manner it ought to be the endeavour of every man to derive his reflections from the objects about him; for it is to no purpose that he alters his position, if his attention continues fixed to the same point. The mind should be kept open to the access of every new idea, and so far disengaged from the predominance of particular thoughts, as easily to accommodate itself to occasional entertainment. A man that has formed this habit of turning every new object to his entertainment, finds in the productions of nature an inexhaustible stock of materials upon which he can employ himself, without any temptations to envy or malevolence; faults, perhaps, seldom totally avoided by those, whose judgment is much exercised upon the works of art. He has always a certain prospect of discovering new reasons for adoring the sovereign Author of the universe, and probable hopes of making some discovery of benefit to others, or of profit to himself. There is no doubt but many vegetables and animals have qualities that might be of great use, to the knowledge of which there is not required much force of penetration, or fatigue of study, but only frequent experiments, and close attention. What is said by the chemists of their darling mercury, is, perhaps, true of every body through the whole creation, that if a thousand lives should be spent upon it, all its properties would not be found out. Mankind must necessarily be diversified by various tastes, since life affords and requires such multiplicity of employments, and a nation of naturalists is neither to be hoped, nor desired; but it is surely not improper to point out a fresh amusement to those who languish in health, and repine in plenty, for want of some source of diversion that may be less easily exhausted, and to inform the multitudes of both sexes, who are burdened with every new day, that there are many shows which they have not seen. He that enlarges his curiosity after the works of nature, demonstrably multiplies the inlets to happiness; and, therefore, the younger part of my readers, to whom I dedicate this vernal speculation, must excuse me for calling upon them, to make use at once of the spring of the year, and the spring of life; to acquire, while their minds may be yet impressed with new images, a love of innocent pleasures, and an ardour for useful knowledge; and to remember, that a blighted spring makes a barren year, and that the vernal flowers, however beautiful and gay, are only intended by nature as preparatives to autumnal fruits.
