 tion of moisture and dryness, and general characteristics, its minute descriptions of the routes of the 

 various Pacific Railroads, and its very able and original discussion of The Origin ok the Prairies, 

 will make this book of the utmost interest and importance to every inhabitant of the United Slates, 

 and especially of the West. 



A writer, in the "Evening Post," who has had access to the proof sheets, says nf it: "This 

 work contains a vast range of information in every department of science. Every page evinces that the 

 author has observed extensively, and thought profoundly on the topics of which he v.rites. Treated in 

 such a spirit. Physical Geography becomes one of the most interesting subjects of knowledge. It is 

 the only work which conveys to the reader a comprehensive idea of the resources of the Great Valley, 

 and of the extent to which they can be expanded."
