otes) fishing along the main shore, as 

 well as on some of the islands in the 

 Santa Barbara Channel, working one 

 place after another as long as each local- 

 ity continues profitable and using a div- 

 ing suit in pursuit of the business. It 

 was stated at the time that a party of 

 Japanese, with headquarters on Carmel 

 Bay (a few miles south of Monterey 

 Bay), left early in August last for the 

 coast of San Luis Obispo County, with 

 the intention of collecting abalenes near 

 Morro Rock. In the following October 

 it was reported that the expedition proved 

 a failure, not because of a scarcity of 

 abalenes, for they were found to be in 

 great abundance, but for miles along 

 the shore the\- were all dead. The ocean 



bed was covered with an oily, bituminous 

 slime, or something of the kind, pre- 

 sumably due to the earthc[uake on April 

 i8, and fatal to the shell-fish. 



The discharge into the sea of poisonous 

 matter, whatever its character, may have 

 occurred before or since the quake of 

 April 1 8, and the disturbance, whenever 

 it occurred, may have been comparatively 

 local and restricted to a limited range 

 along the main shore. 



The postmaster at Morro informed me 

 that the shock of April i8 was very slight 

 at that place — so slight that "some people 

 were not awakened by it." 



Point Pinos is about 90 miles south of 

 the entrance of San Francisco Bav, and 

 Morro is 100 miles south of Point Pinos. 



FOR TEACHING PHYSIOGRAPHY 



THE United States Geological Sur- 

 vey has selected a list of 100 of 

 its atlas sheets for the purpose of illus- 

 trating a variety of physiographic forms. 

 This has been published as a leaflet, giv- 

 ing under each sheet the principal physio- 

 graphic form or forms which it illus- 

 trates, and with this list is a cross-refer- 

 ence list showing the sheets on which 

 each topographic form is illustrated. For 

 instance, aggrading streams are illus- 

 trated on the Maxwell (Cal.) sheet, 

 alluvial fans on the Cucamonga ( Cal. ) 

 sheet, anticlinal mountains on the Cloud 

 Peak (Wyo.) sheet, denuded plateaus 

 on the Corazon (N. Mex.) sheet, dissect 

 fault blocks on the Needles (Ariz.) 

 sheet, glaciated topography on the Becket 

 (Mass.) sheet, lacustrine plains on the 

 Amargosa (Nev.-Cal. ) sheet, kettle mo- 

 raines on the Edgely (X. Dak.) sheet, 

 wind erosion on the Coldwater (Kans.) 

 sheet, etc. These atlas sheets, with the 

 aid of such a list, will prove very helpful 

 to teachers of physiography. 



This set of 100 sheets with the leaflet 

 will be sold for $3 by the U. S. Geological 

 Survey, Washington, D. C.
