TESTIMONIALS. 



From wh&t I know of PROF. GUYOT'S Wall Maps, etc., I have no hesitation in saying 

 that, both as to method and execution, they are incomparably superior to anything of the 

 kind thus far published ; and, in connection with the series of text-books by the same 

 author, which, I understand, are soon to be published, they will form the most valuable 

 means for the study of geography, in which department there is urgent necessity for new 

 books adapted to the present advanced state of the 'science. In fact, it is the simple truth, 

 that no other geographer living understands the relations of the physical feature of 

 our earth so well, or knows how to present them to students with suck simplicity 

 and clearness, as PROF. GUYOT.

PROFESSOR GUYOT, the author of "The Earth and Man," is one of the ablest Physical 

 Geographers in the world, and is remarkable not only for his general knowledge and his 

 comprehensive views, but also for the simplicity of his method of presenting his favorite 

 science to readers or hearers. His Maps exhibit in a striking manner all these qualities, 

 being eminent for their clearness and for their bold exhibition of the grander truths, aside 

 from unimportant details. 



They are, therefore, peculiarly well adapted for Class Instruction, and for the children 

 of our Common Schools, as well as those more advanced. The same will, I feel assured, be 

 true of his Text-Books on Geography.

PROFESSOR GUYOT, who has been from the first establishment of the Smithsonian In- 

 stitution one of its most esteemed collaborators, is preparing a series of Maps and Manuals 

 of Political and Physical Geography, which, from my personal knowledge of the extensive 

 learning and conscientious industry of the author, I can warmly recommend to the public. 



The Wall Maps of the series which have already appeared are, in regard to exposition 

 of scientific principles, accuracy of detail, amount of information, and general style of exe- 

 cution, greatly superior to any works of the kind previously published in this country.
