colate. They have sluice gates and the 

 fish come in from outside. They are 

 also caught in the open sea and brought 

 to the enclosures, but practically no 

 attempt at fish culture is made. The 

 fish in the sea-ponds are mostly ama- 

 ama, or mullet, and the awa, but a 

 larger variety is found in the fresh and 

 brackish water ponds. There are prob- 

 ably not more than half as many ponds 

 in use now as there were thirty years 

 ago, owing chiefly to the disappearance 

 of the native population, but partly be- 

 cause the interior ponds can be used 

 for the culture of rice and taro. There 

 are, however, still on the Island of 

 Oahu fish ponds, several of which are 

 a hundred acres or more in size. 

 These ponds supply annually more 

 than half a million pounds of fish, 

 valued at $140,000. 



SCIENTIFIC ITEMS. 

 The British Association for the Ad-

 Ray Lankester, director of the British 

 Museum of Natural History, has been 

 elected president for 1906. — The sev- 

 enty-seventh meeting of German Men 

 of Science and Physicians was held in 

 Meran last month under the presi- 

 dency of Dr. Franz von Winckel, pro- 

 fessor of gynecology, at Munich. — The 

 American Anthropological Association 

 has met at San Francisco under the 

 presidency of Dr. Frederic Ward Put- 

 nam, of Harvard University and the 

 University of California. The program

 papers. 



Professor T. C. Chamberlin, of the

 U. S. Geological Survey, who, on the 

 nomination of the National Geographic 

 Society, was placed in charge of the 

 scientific work of the expedition, re- 

 ports that a considerable amount of 

 scientific work has been accomplished. 



When the Popular Science 

 Monthly was established in 1872, the 

 first number was issued in November, 

 and for the past thirty-three years the 

 volumes have begun with the Novem- 

 ber and May numbers. Most subscrip- 

 tions to the Monthly, however, begin 

 with January, and it is in the interest 

 of subscribers to receive complete vol- 

 umes. It is also more convenient in 

 quoting a journal for the year to 

 correspond with the volume. We shall 

 consequently include eight numbers in 

 the present volume. The index will 

 be given in the December number and 

 volume LXVI1I. will begin in January, 

 100G.
