" Whatever Professor Bailey writes is interesting reading. He has the rare 

 gift of an entertaining style, and what he writes people want to read. All his 

 previous books have beni widely read, and this will prove no exception to the 

 well-established rule. The secret of this popularity, if there be any secret about 

 it, is that when he writes he has something new to say, something based 

 upon experiences and observations. These are by no means all his own, for 

 he has the ability to see with the eyes of other people, as well as with his 

 own. He is thus able to bring into his pages a rich mass of new matter, which 

 gives them aditiomil interest and value." PROFESSOR C. E. BESSEY, 



University of Nebraska, in " Science."
