THE PROGRESS OF SCIENCE.

Assuan, took extensive photographs in | 

 search for a possible planet between the 

 sun and Mercury. The photographs 

 have probably not as yet been ex- 

 amined, but Professor Perrine's results 

 in Sumatra make the existence of such 

 a planet unlikely. 



As events of general interest in con- 

 nection with the eclipse, it. may be 

 noted that the Spaniards made special 

 arrangements when the circumstances 

 were so auspicious for them. Thus 

 the Jesuit Observatory, at Tortosa, was 

 in the line of the shadow, and no fewer 

 than eighty Jesuit fathers skilled in 

 astronomy assembled there. Japan 

 has been justly praised for not letting 

 its scientific and educational activities 

 be interrupted by the war. and it seems 

 fair to note that Russia was repre- 

 sented by several expeditions in Spain 

 and Egypt. A large party, chiefly of 

 amateur astronomers, observed the 

 eclipse from the steamer Arcadia. 



As it will be some time before the 

 scientific results will be made public, 

 readers of this Jotjrxal may be re- 

 ferred to the article by Director Camp- 

 bell, of the Lick Observatory, printed 

 in the issue of June of last year for an 

 admirable account of the problems of 

 the present eclipse. It may also be 



well to mention the articles on the two 

 preceding eclipses that were observed, 

 that by Professor Perrine on the 

 eclipse of 1901 (August, 1(10.3), and 

 that by Secretary Langly on the eclipse 

 of 1900 (July, 1900). 



THE FISH PONDS OF THE 

 HAWAIIAN ISLANDS. 

 The last part of an extensive study 

 of the fishes of the Hawaiian Islands, 

 by President David Starr Jordan and 

 Dr. W. Barton Evermann, published by 

 the United States Fish Commission, 

 contains a discussion of the commercial 

 fisheries by Mr. John M. Cobb. He 

 describes the fish ponds of the islands, 

 which are on a much larger scale than 

 can be found elsewhere in the United 

 States. Some of the ponds are sup- 

 posed to have been built as long as two 

 hundred and fifty years ago, and are 

 attributed by the natives to a mythical 

 race of dwarfs, distinguished for cun- 

 ning industry and engineering skill. 

 The ponds are mostly in the bays in- 

 denting the shores of the islands, but 

 there are also many ponds in the in- 

 terior, and at least one is an old 

 volcanic crater. In the sea ponds the 

 walls are about five feet in width, and 

 are built loosely to let the water per-
