Timely Books of General Interest 



Tlie Pliilippiue Islands and Their People 



A Eecord of Personal Observation and Experience, with a Short Summary of the More Important 

 Facts in the History of the Archipelago. By Dean C. Worcester, Assistant Professor of Zoology, 

 University of Michigan. Svo. Cloth Extra. Price, $4.00. 



This is no mere record of an ordinary traveller. Professor Worcester twice visited the Philippines. 

 On his second trip he remained nearly three years in the islands, and a royal order from the Spanish Govern- 

 ment materially aided him in gathering information. Dr. Frank S. Bourns, now on the staff of the com- 

 mander-in-chief of our forces at Manila, was with the author on both of his visits, and has furnished a large 

 number of photographs from which the illustrations have been made. 



The Control of the Tropics 



By Benjamin KiDD, Author of " Social Evolution." ISino. Cloth. Price, TS cents. 



The appearance of Mr. Kidd's book is particularly timely, and as it deals especially with problems 

 which are now confronting us, its circulation has been very extended ; the first edition is about exhausted, 

 and a second is in active preparation. 



" Mr. Kidd's thinking is close and logical and his conclusions are well worthy of thoughtful consider- 

 ation. " — The Tribune, Chicago. 



The Rise and Growth of American Politics 



A Sketch of Constitutional Development. By Heney Jones FoED. ISino. Cloth. $1.50. 



Mr. Ford has set himself a difficult task. From their inception he reviews our politics from the 

 standpoint of an outsider, as Mr. Bryce did in his "American Commonwealth.' Yet it is an explanation of 

 causes rather than a narrative of events, aiming to give the reader an understanding of the actual system of 

 government under which we live. 



To the student, whether of constitutional history or of political parties, the book is not only readable, 

 but of great value.

 Queen's University, Kingston, Canada ; Author of " Kant and his English Critics," etc. Snd Edition.

and partially rewritten text.

By Henky Van Dyke, D.D. (Princeton, Harvard, Yale), LL.D. (Union), Pastor of the Brick Church 

 • in New York. Sixth Edition Revised, with a New Preface. 12nio. Cloth. Price, $1.25.

 issued in a cheaper form and will doubtless attract many new readers. 



" It is the best one of a very few books I should venture to put into the hands of a young man troubled 

 by doubts." — James O. Mueeay, D.D., Dean of PHnceton University.
