But a scene of less grandeur, yet more beautiful, is the view of the solitary author himself in his own study—so deeply occupied, that whatever passes before him never reaches his observation, while, working more than twelve hours every day, he still murmurs as the hour strikes; the volume still lies open, the page still importunes—"And whence all this business?" He has made a discovery for us! that never has there been anything important in the active world but what is reflected in the literary—books contain everything, even the falsehoods and the crimes which have been only projected by men! This solitary man of genius is arranging the materials of instruction and curiosity from every country and every age; he is striking out, in the concussion of new light, a new order of ideas for his own times; he possesses secrets which men hide from their contemporaries, truths they dared not utter, facts they dared not discover. View him in the stillness of meditation, his eager spirit busied over a copious page, and his eye sparkling with gladness! He has concluded what his countrymen will hereafter cherish as the legacy of genius—you see him now changed; and the restlessness of his soul is thrown into his very gestures—could you listen to the vaticinator! But the next age only will quote his predictions. If he be the truly great author, he will be best comprehended by posterity, for the result of ten years of solitary meditation has often required a whole century to be understood and to be adopted. The ideas of Bishop BERKELEY, in his "Theory of Vision," were condemned as a philosophical romance, and now form an essential part of every treatise of optics; and "The History of Oracles," by FONTENELLE, says La Harpe, which, in his youth, was censured for its impiety, the centenarian lived to see regarded as a proof of his respect for religion.

"But what influence can this solitary man, this author of genius, have on his nation, when he has none in the very street in which he lives? and it may be suspected as little in his own house, whose inmates are hourly practising on the infantine simplicity which marks his character, and that frequent abstraction from what is passing under his own eyes?"

This solitary man of genius is stamping his own character on the minds of his own people. Take one instance, from others far more splendid, in the contrast presented by FRANKLIN and Sir WILLIAM JONES. The parsimonious habits, the money-getting precepts, the wary cunning, the little scruple about means, the fixed intent upon the end, of Dr. FRANKLIN, imprinted themselves on his Americans. Loftier feelings could not elevate a man of genius who became the founder of a trading people, and who retained the early habits of a journeyman; while the elegant tastes of Sir WILLIAM JONES could inspire the servants of a commercial corporation to open new and vast sources of knowledge. A mere company of merchants, influenced by the literary character, enlarges the stores of the imagination and provides fresh materials for the history of human nature.

FRANKLIN, with that calm good sense which is freed from the passion of imagination, has himself declared this important truth relating to the literary character:—"I have always thought that one man of tolerable abilities may work great changes and accomplish great affairs among mankind, if he first forms a good plan; and cutting off all amusements, or other employments that would divert his attention, makes the execution of that same plan his sole study and business." Fontenelle was of the same opinion, for he remarks that "a single great man is sufficient to accomplish a change in the taste of his age." The life of GRANVILLE SHARP is a striking illustration of the solitary force of individual character.

It cannot be doubted that the great author, in the solitude of his study, has often created an epoch in the annals of mankind. A single man of genius arose in a barbarous period in Italy, who gave birth not only to Italian, but to European literature. Poet, orator, philosopher, geographer, historian, and antiquary, PETRARCH kindled a line of light through his native land, while a crowd of followers hailed their father-genius, who had stamped his character on the age. DESCARTES, it has been observed, accomplished a change in the taste of his age by the perspicacity and method for which he was indebted to his mathematical researches; and "models of metaphysical analysis and logical discussions" in the works of HUME and SMITH have had the same influence in the writings of our own time.

Even genius not of the same colossal size may aspire to add to the progressive mass of human improvement by its own single effort. When an author writes on a national subject, he awakens all the knowledge which slumbers in a nation, and calls around him, as it were, every man of talent; and though his own fame may be eclipsed by his successors, yet the emanation, the morning light, broke from his solitary study. Our naturalist, RAY, though no man was more modest in his claims, delighted to tell a friend that "Since the publication of his catalogue of Cambridge plants, many were prompted to botanical studies, and to herbalise in their walks in the fields." Johnson has observed that "An emulation of study was raised by CHEKE and SMITH, to which even the present age perhaps owes many advantages, without remembering or knowing its benefactors. ROLLIN is only a compiler of history, and to the antiquary he is nothing! But races yet unborn will be enchanted by that excellent man, in whose works 'the heart speaks to the heart,' and whom Montesquieu called 'The Bee of France'." The BACONS, the NEWTONS, and the LEIBNITZES were insulated by their own creative powers, and stood apart from the world, till the dispersers of knowledge became their interpreters to the people, opening a communication between two spots, which, though close to each other, were long separated —the closet and the world! The ADDISONS, the FONTENELLES, and the FEYJOOS, the first popular authors in their nations who taught England, France, and Spain to become a reading people, while their fugitive page imbues with intellectual sweetness every uncultivated mind, like the perfumed mould taken up by the Persian swimmer. "It was but a piece of common earth, but so delicate was its fragrance, that he who found it, in astonishment asked whether it were musk or amber. 'I am nothing but earth; but roses were planted in my soil, and their odorous virtues have deliciously penetrated through all my pores: I have retained the infusion of sweetness, otherwise I had been but a lump of earth!'"

I have said that authors produce their usefulness in privacy, and that their good is not of immediate application, and often unvalued by their own generation. On this occasion the name of EVELYN always occurs to me. This author supplied the public with nearly thirty works, at a time when taste and curiosity were not yet domiciliated in our country; his patriotism warmed beyond the eightieth year of his age, and in his dying hand he held another legacy for his nation. EVELYN conveys a pleasing idea of his own works and their design. He first taught his countrymen how to plant, then to build: and having taught them to be useful without doors, he then attempted to divert and occupy them within doors, by his treatises on chalcography, painting, medals, libraries. It was during the days of destruction and devastation both of woods and buildings, the civil wars of Charles the First, that a solitary author was projecting to make the nation delight in repairing their evil, by inspiring them with the love of agriculture and architecture. Whether his enthusiasm was introducing to us a taste for medals and prints, or intent on purifying the city from smoke and nuisances, and sweetening it by plantations of native plants, after having enriched our orchards and our gardens, placed summer-ices on our tables, and varied even the salads of our country; furnishing "a Gardener's Kalendar," which, as Cowley said, was to last as long "as months and years;" whether the philosopher of the Royal Society, or the lighter satirist of the toilet, or the fine moralist for active as well as contemplative life—in all these changes of a studious life, the better part of his history has not yet been told. While Britain retains her awful situation among the nations of Europe, the "Sylva" of EVELYN will endure with her triumphant oaks. In the third edition of that work the heart of the patriot expands at its result; he tells Charles II. "how many millions of timber trees, besides infinite others, have been propagated and planted at the instigation and by the sole direction of this work." It was an author in his studious retreat who, casting a prophetic eye on the age we live in, secured the late victories of our naval sovereignty. Inquire at the Admiralty how the fleets of Nelson have been constructed, and they can tell you that it was with the oaks which the genius of EVELYN planted.[A]

[Footnote A: Since this was first printed, the "Diary" of EVELYN has appeared; and although it could not add to his general character, yet I was not too sanguine in my anticipations of the diary of so perfect a literary character, who has shown how his studies were intermingled with the business of life.]

The same character existed in France, where DE SERRES, in 1599, composed a work on the cultivation of mulberry-trees, in reference to the art of raising silkworms. He taught his fellow-citizens to convert a leaf into silk, and silk to become the representative of gold. Our author encountered the hostility of the prejudices of his times, even from Sully, in giving his country one of her staple commodities; but I lately received a medal recently struck in honour of DE SERRES by the Agricultural Society of the Department of the Seine. We slowly commemorate the intellectual characters of our own country; and our men of genius are still defrauded of the debt we are daily incurring of their posthumous fame. Let monuments be raised and let medals be struck! They are sparks of glory which might be scattered through the next age!

There is a singleness and unity in the pursuits of genius which is carried on through all ages, and will for ever connect the nations of the earth. THE IMMORTALITY OF THOUGHT EXISTS FOR MAN! The veracity of HERODOTUS, after more than two thousand years, is now receiving a fresh confirmation. The single and precious idea of genius, however obscure, is eventually disclosed; for original discoveries have often been the developments of former knowledge. The system of the circulation of the blood appears to have been obscurely conjectured by SERVETUS, who wanted experimental facts to support his hypothesis: VESALIUS had an imperfect perception of the right motion of the blood: CÆSALPINUS admits a circulation without comprehending its consequences; at length our HARVEY, by patient meditation and penetrating sagacity, removed the errors of his predecessors, and demonstrated the true system. Thus, too, HARTLEY expanded the hint of "the association of ideas" from LOCKE, and raised a system on what LOCKE had only used for an accidental illustration. The beautiful theory of vision by BERKELEY, was taken up by him just where LOCKE had dropped it: and as Professor Dugald Stewart describes, by following out his principles to their remoter consequences, BERKELEY brought out a doctrine which was as true as it seemed novel. LYDGATE'S "Fall of Princes," says Mr. Campbell, "probably suggested to Lord SACKVILLE the idea of his 'Mirror for Magistrates'." The "Mirror for Magistrates" again gave hints to SPENSER in allegory, and may also "have possibly suggested to SHAKSPEARE the idea of his historical plays." When indeed we find that that great original, HOGARTH, adopted the idea of his "Idle and Industrious Apprentice," from the old comedy of Eastward Hoe, we easily conceive that some of the most original inventions of genius, whether the more profound or the more agreeable, may thus be tracked in the snow of time.
