This work possesses a double interest; first, as a most stirring and graphic delineation of life, character and scenery on the borders of Texas, and second, as indicating an almost unknown region of the Continent, rich in gold mines and wealth of various kinds, and tempting both curiosity and cupidity to its exploration. Mr. Webber proposes to head an expedition of some sixty men, to be called the “Centralia Exploring Expedition to California, via the valleys of the Pecos, the Gila, and Colorado of the West,” for the purpose of discovery and profit; and in the course of this delightful book of adventure, he spreads before his readers the evidence he possesses of the existence of the region into which he desires to penetrate. If his expedition succeed we have little doubt that it will be one of the most interesting and romantic since the time of Cortez; and the leader himself has qualities of valor, endurance and chivalric sentiment, sufficient to carry him through the difficulties of any enterprise, however arduous. Apart from the information relating to a new gold region, Mr. Webber’s volumes possess an engrossing interest as records of adventure. The author has a sureness and vividness of conception, and a power of expression, which combined make his delineations singularly fresh and life-like. To read this book is the next best thing to viewing the objects it describes. It displays a representative genius of a high order, and if the author would concentrate his energies, he might produce a novel which would give him a place in the front rank of our original minds. * * * * * _Rural Letters and other Records of Thought at Leisure, written in the intervals of more hurried Literary Labor.
