144 SOUTHERN CALIFORNIA ACADEMY OF SCIENCES. 



Notes. 



Up to July I, Phcenix showed 175 degrees of heat in excess of the 

 normal, yet the effect on the staff of the Agricultural Experiment Station 

 seems to have been decidedly stimulating. No less than four Bulletins 

 (see "Publicaiions Received ") have been issued from that station in less 

 than a month. In one Lippia nodiflora, in use in dry localities as a sub- 

 stitute for grass in lawns, is recommended as a soil binder in soils liable to 

 wash or on banks of irrigating ditches. The result of "Irrigation at the 

 Station Farm," and "Utilizing our water supply" at the farm is ably set 

 forth by Prof. McClatchie and the encouraging results attained commend 

 the pamphlets to every California farmer. All dwellers in the warmer 

 districts of the south-west will find in "The cool side of a house in Arizona" 

 the best method of building and the scientific reasons therefor. 



F. P. Brackett, Professor of Mathematics in Pomona College has a 

 leave of absence for the coming School year. He will spend the year in 

 study and investigation at Clarke University, Worcester, Mass , where he is 

 the recipient of an honorary fellowship. The following summer he expects 

 to spend at Yerkes Observatory in Spectroscopic investigation.

GEOLOGICAL SECTION. 



Los AngeIvES, Cai. , October 27th, 1902. 



The p^eological Section met at the Woman's Club Rooms at 8 p. m. 

 Chairman Geo. W. Parsons called the meeting to -order. Minutes of pre- 

 vious meetings read, corrected and approved. The Chairman introduced 

 Mr. David C Cunningharo as the speaker of the evening, who gave a very 

 interesting description of Chile, its climate, geology and topography. 



He stated in parts, that the natural advantages ot Chile would include 

 all the marvels of California, Colorado, Arizona, Nevada, Oregon and 

 Alaska, as to climate, minerals, desert, forests, agriculture, mountains, 

 rivers and lakes, while its climate ranges all the way from tropic to arctic, 

 with the same variation of rainfall. 



A portion of the inteiior having fertile plains furnishing wheat, cattle 

 and fruits for the less tropical regions in the North. The speaker gave a 

 thorough description of its mines and mineral formations, its nitrate and 

 borax deposits, some of which were located at an elevation of 12,000 feet 

 above sea level. 



In regard to earthquakes, there they realize the genuine article, which 

 was frequent' y accompanied with tidal waves which were occasionally very 

 destructive. His description of a trip of 17,200 feet of an altitude up the 

 mountains was full of interest. He also gave a description of the Birds and 

 Animals indigenous to the section,
