The _New York Columbian_ says:-- "The author has before given the public a valuable work upon the Lead Mines of Missouri, and, if we mistake not, a book of instructions upon the manufacture of glass.

He is advantageously known as a man of science and literary research, and well qualified to turn to beneficial account the mass of information he must have collected in his tour through that interesting part of the country, which has attracted universal attention, though our knowledge of it has hitherto been extremely limited.

We think there is no fear that the just expectations of the public will be disappointed; but that the book will be found to furnish all the valuable and interesting information that the subject and acquirements of the writer promised, conveyed in a chaste and easy style appropriate for the journalist--occasionally enlivened by animating descriptions of scenery.

The author has not suffered his imagination to run wild from a foolish vanity to win applause as a fine writer, when the great object should be to give the reader a view of what he describes, as far as language will permit, in the same light in which he beheld it himself.

He aims to give you a just and true account of what he has seen and heard, and his book will be referred to as a record of facts by the learned and scientific at home and abroad.
