Mr. I. in his "Introduction," informs us that his work "grew out of a private correspondence, which the author, at the solicitation of his friends, has been led to throw into the present form, modifying in a great measure the epistolary vein, and excluding, so far as possible, such portions of the original papers as were of too personal a nature to be intruded upon the majesty of the public--while he has embodied, so far as was compatible with the new arrangement, every thing likely to interest the general reader." The aim of the writer, we are also told, has been to present the result of his experience and observations during a residence of several years in that district of our country which gives the title to the work. It is, indeed, a matter for wonder that a similar object has never been carried into execution before. The South-West, embracing an extensive and highly interesting portion of the United States, is completely _caviare_ to the multitude. Very little information, upon whose accuracy reliance may be placed, has been hitherto made public concerning these regions of Eldorado--and were the volumes of Professor Ingraham absolutely worthless in every other respect, we should still be inclined to do them all possible honor for their originality in subject matter. But the "South-West" is very far from worthless. In spite of a multitude of faults which the eye of rigid criticism might easily detect--in spite of some inaccuracies in point of fact, many premature opinions, and an inveterate habit of writing what neither is, nor should be English, the Professor has succeeded in making a book, whose abiding interest, coming home to the bosoms and occupations of men, will cause any future productions of the same author to be looked for with anxiety.
