The theoretical historian communicates his own character to his history; and if, like Robertson, he be profound and politic, he detects the secret motives of his actors, unravels the webs of cabinet councils, explains projects that were unknown, and details stratagems which never took place. When we admire the fertile conceptions of the Queen Regent, of Elizabeth, and of Bothwell, we are often defrauding Robertson of whatever admiration may be due to such deep policy.

When Hume received from Dr. Birch Forbes's Manuscripts and Murdin's State-papers, in great haste he writes to his brother historian:—"What I wrote you with regard to Mary, &c., was from the printed histories and papers. But I am now sorry to tell you that by Murdin's State-papers, the matter is put beyond all question. I got these papers during the holidays by Dr. Birch's means; and as soon as I read them I ran to Millar, and desired him very earnestly to stop the publication of your history till I should write to you, and give you an opportunity of correcting a mistake so important; but he absolutely refused compliance. He said that your book was now finished; that the whole narrative of Mary's trial must be wrote over again; that it was uncertain whether the new narrative could be brought within the same compass with the old: that this change would require the cancelling a great many sheets; that there were scattered passages through the volumes founded on your theory." What an interview was this of Andrew Millar and David Hume! truly the bibliopole shone to greater advantage than the two theoretical historians! And so the world had, and eagerly received, what this critical bookseller declared "required the new printing (that is, the new writing) of a great part of the edition!"

When this successful history of Scotland invited Robertson to pursue this newly-discovered province of philosophical or theoretical history, he was long irresolute in his designs, and so unpractised in those researches he was desirous of attempting, that his admirers would have lost his popular productions, had not a fortunate introduction to Dr. Birch, whose life had been spent in historical pursuits, enabled the Scottish historian to open many a clasped book, and to drink of many a sealed fountain. Robertson was long undecided whether to write the history of Greece, of Leo X., that of William III. and Queen Anne, or that of Charles V., and perhaps many other subjects.

We have a curious letter of Lord Orford's, detailing the purport of a visit Robertson paid to him to inquire after materials for the reigns of William and Anne; he seemed to have little other knowledge than what he had taken upon trust. "I painted to him," says Lord Orford, "the difficulties and the want of materials—but the booksellers will out-argue me." Both the historian and "the booksellers" had resolved on another history: and Robertson looked upon it as a task which he wished to have set to him, and not a glorious toil long matured in his mind. But how did he come prepared to the very dissimilar subjects he proposed? When he resolved to write the history of Charles V., he confesses to Dr. Birch: "I never had access to any copious libraries, and do not pretend to any extensive knowledge of authors; but I have made a list of such as I thought most essential to the subject, and have put them down as I found them mentioned in any book I happened to read. Your erudition and knowledge of hooks is infinitely superior to mine, and I doubt not but you will be able to make such additions to my catalogue as may be of great use to me. I know very well, and to my sorrow, how servilely historians copy from one another, and how little is to be learned from reading many books; but at the same time, when one writes upon any particular period, it is both necessary and decent for him to consult every book relating to it upon which he can lay his hands." This avowal proves that Robertson knew little of the history of Charles V. till he began the task; and he further confesses that "he had no knowledge of the Spanish or German," which, for the history of a Spanish monarch and a German emperor, was somewhat ominous of the nature of the projected history.

Yet Robertson, though he once thus acknowledged, as we see, that he "never had access to any copious libraries, and did not pretend to any extensive knowledge of authors," seems to have acquired from his friend, Dr. Birch, who was a genuine researcher in manuscripts as well as printed books, a taste even for bibliographical ostentation, as appears by that pompous and voluminous list of authors prefixed to his "History of America;" the most objectionable of his histories, being a perpetual apology for the Spanish Government, adapted to the meridian of the court of Madrid, rather than to the cause of humanity, of truth, and of philosophy. I understand, from good authority, that it would not be difficult to prove that our historian had barely examined them, and probably had never turned over half of that deceptive catalogue. Birch thought so, and was probably a little disturbed at the overwhelming success of our eloquent and penetrating historian, while his own historical labours, the most authentic materials of history, but not history itself, hardly repaid the printer. Birch's publications are either originals, that is, letters or state-papers; or they are narratives drawn from originals, for he never wrote but from manuscripts. They are the true materia historica.

Birch, however, must have enjoyed many a secret triumph over our popular historians, who had introduced their beautiful philosophical history into our literature; the dilemma in which they sometimes found themselves must have amused him. He has thrown out an oblique stroke at Bobertson's "pomp of style, and fine eloquence," "which too often tend to disguise the real state of the facts."[A] When he received from Robertson the present of his "Charles V.," after the just tribute of his praise, he adds some regret that the historian had not been so fortunate as to have seen Burghley's State-papers, "published since Christmas," and a manuscript trial of Mary, Queen of Scots, in Lord Boyston's possession. Alas! such is the fate of speculative history; a Christmas may come, and overturn the elaborate castle in the air. Can we forbear a smile when we hear Robertson, who had projected a history of British America, of which we possess two chapters, when the rebellion and revolution broke out, congratulate himself that he had not made any further progress? "It is lucky that my American History was not finished before this event; how many plausible theories that I should have been entitled to form are contradicted by what has now happened!" A fair confession!

Let it not be for one moment imagined that this article is designed to depreciate the genius of Hume and Robertson, who are the noblest of our modern authors, and exhibit a perfect idea of the literary character.

Forty-four years ago, I transcribed from their originals the correspondence of the historian with the literary antiquary. For the satisfaction of the reader, I here preserve these literary relics.
