DEAR SIR,--Lyman was mortified that he could not visit Monticello. He is gone to Europe a second time. I regret that he did not see you, he would have executed any commission for you in the literary line, at any pain or any expense. I have many apprehensions for his health, which is very delicate and precarious, but he is seized with the mania of all our young clerical spirits for foreign travel; I fear they will lose more than they acquire, they will lose that unadulterated enthusiasm for their native country, which has produced the greatest characters among us. Oh! Lord! Do you think that Protestant Popedom is annihilated in America? Do you recollect, or have you ever attended to the ecclesiastical strifes in Maryland, Pennsylvania, New York, and every part of New England? What a mercy it is that these people cannot whip, and crop, and pillory, and roast, _as yet_ in the United States! If they could, they would. Do you know the General of the Jesuits, and consequently all his host, have their eyes on this country? Do you know that the Church of England is employing more means and more art, to propagate their demi-popery among us, than ever? Quakers, Anabaptists, Moravians, Swedenborgians, Methodists, Unitarians, Nothingarians in all Europe are employing underhand means to propagate their sectarian system in these States. The multitude and diversity of them, you will say, is our security against them all. God grant it. But if we consider that the Presbyterians and Methodists are far the most numerous and the most likely to unite, let a George Whitefield arise, with a military cast, like Mahomet or Loyola, and what will become of all the other sects who can never unite? My friends or enemies continue to overwhelm me with books. Whatever may be their intention, charitable or otherwise, they certainly contribute to continue me to vegetate, much as I have done for the sixteen years last past. Sir John Malcolm's history of Persia, and Sir William Jones' works, are now poured out upon me, and a little cargo is coming from Europe. What can I do with all this learned lumber? Is it necessary to salvation to investigate all these Cosmogonies and Mythologies? Are Bryant, Gebelin, Dupuis, or Sir William Jones, right? What a frown upon mankind was the premature death of Sir William Jones! Why could not Jones and Dupuis have conversed or corresponded with each other? Had Jones read Dupuis, or Dupuis Jones, the works of both would be immensely improved, though each would probably have adhered to his system. I should admire to see a counsel composed of Gebelin, Bryant, Jones and Dupuis. Let them live together and compare notes. The human race ought to contribute to furnish them with all the books in the Universe, and the means of subsistence.
