There is a very charming book, brightly written, and dealing with an interesting people, which reaches very high in the literature of travel. We refer to Lady Eastlake's "Residence on the Shores of the Baltic, described in a series of Letters," in which, with a polished pen and a quick observation, she sets before us the patriarchal simplicity of life and honest character of the Esthonians. Travel-books by ladies were rare at the time that Lady Eastlake (then Miss Rigby) wrote, and the success of her work was influenced, no doubt, by this rarity; but its reputation may well rest upon its genuine merit. Only, justice compels us to say that writing of almost equal merit, sometimes of superior, is now poured out every year, nay, every month, by adventurers of the "other sex." A female traveller has ceased to be a _rara avis_; delicately-nurtured women now climb Mont Blanc or penetrate into the Norwegian forests, or cross the Pacific, or traverse sandy deserts, or visit remote isles, in company with their husbands and brothers, or "unprotected." This great and rapid increase in the number of female travellers is partly due, no doubt, to the greater facilities of locomotion; but we believe it is also due to the greater freedom which women of late years have successfully claimed, and to the consequent development of powers and faculties, their possession of which was long ignored or denied. MRS. TROLLOPE. Frances Milton, so well known in English literature under her married name of Trollope, was born at Heathfield Parsonage in Hampshire, in 1787. She received, under her father's supervision, a very careful education, and developed her proclivities for literary composition at an early age. She was but eighteen when she accepted the hand of Mr. Thomas A. Trollope, a barrister, and the cares and duties of married life for some years diverted her energies into a different channel. The true bent of her talents--a sharp, bold, and somewhat coarse satire--she did not discover until after her visit to the United States (1829-1831). There she conceived an antipathy to American manners and customs, which seems to have awakened her powers of sarcasm, and resulted in her first publication, "Domestic Life of the Americans." The peculiarities she had found so obnoxious she sketched with a strong, rough hand; and the truth of her drawing was proved by the wrathful feelings which it provoked in the breasts of its victims. Reading it now, we are naturally inclined to think it a caricature and an exaggeration; but it is only fair to remember that, since its appearance half a century ago, a great change has come over the temper of American society. The great fault of Mrs. Trollope is, that she is always a critic and never a judge. She looks at everything through the magnifying lens of a microscope. And, again, it must be admitted that she is often vulgar; whatever the want of refinement in American society, it is almost paralleled by the want of
