A NEW HARBOR IN PORTO RICO 



ANOTHER good harbor in Porto 

 Rico has been added to those which 

 the labors of the U. S. Coast and Geo- 

 detic Survey have introduced to the 

 world at large. Although every harbor 

 in Porto Rico has doubtless long been 

 known to fishermen and local traders, 

 the cartographers knew nothing about 

 Ensenada Honda, Jobos, or Guyanilla 

 until the detailed hydrographic surveys 

 of the Coast Survey were published. 



To the list above given may now be 

 added Boqueron Bay, which has just 

 been surveyed. It lies ten miles to the 

 southward of Mayaguez and four miles 

 north of Cabo Jojo, the southwestern 

 point of Porto Rico. 



Boqueron Bay is an indentation on the 

 coast about two miles deep and two miles 



wide at the mouth. It is protected by 

 a coral reef across the mouth, through 

 which two passages lead into the harbor. 

 Through the northernmost, close under 

 point Guaniquilla, four fathoms can be 

 carried, while the passage just south of 

 the middle of the reef has a depth of six 

 fathoms. Once inside, good holding 

 ground of not less than four fathoms is 

 found over an area of about one and 

 one-half square miles. The water shoals 

 towards the head of the bay where the 

 small town of Boqueron is situated. 

 This forms the commercial outlet for 

 the valley of the Borinquen River and of 

 the region as far back as the town of 

 Eajas. This tributary region- produces 

 considerable quantities of sugar, mo- 

 lasses, and cocoauuts.

GEOGRAPHIC LITERATURE 



The Romance of the Colorado River. 



By Frederick S. Dellenbaugh. With 



maps and illustrations. Pp. 800. 



New York : G. P. Putnam's Sons. 



This work is an account of the ex- 

 ploration of this wonderful river from 

 the time of Alarcon, Melchior Diaz, and 

 the friars of the early Spanish days up 

 through the explorations of early hunt- 

 ers and trappers, the army explorations, 

 and finally the two expeditions of Pow- 

 ell. It is not generally known that 

 Powell made two descents of the Colo- 

 rado — the first, the narrative of which 

 is well known, in 1869, and a second in 

 the years 1871 and 1872. The story of 

 this second trip through the series of 

 wonderful canons is here told for the 

 first time and by a member of the ex- 

 pedition. Powell's second expedition 

 through the canons of the Green and 

 Colorado necessarily followed the same 

 route as his first, but the passage down 

 the river was slow and was interrupted 

 by many side trips, for the study of the 



geology and physiography of this won" 

 derfully interesting region ; so while 

 the first expedition took but a little over 

 three months, in the second passage of 

 the canons, which ended at the mouth 

 of Kanab Creek, some sixteen months 

 were expended, mainly in exploration 

 of the surrounding regions. The story 

 is fascinating and well told, for the 

 author is an artist with the pen as with 

 the brush. The book is beautifully 

 printed on heavy paper and is amply 

 and fitly illustrated. H. G.

 Mr Frankenfield gives a permanent

 dentedly high floods of 1903 in the 

 Mississippi watershed, and of the work 

 of the U. S. Weather Bureau in con- 

 nection with the floods. The high water
