198 Notes and News. [zoe 



Professor Daniel C. Eaton, Yale University, New Haven, 

 Conn., desires specimens of Sphagnum, or Bog Mosses, from Cali- 

 fornia. They have been found in swamps near Mendocino City; 

 at the head of Williams Lake, near Lassen Peak; in wet meadows, 

 Mariposa Grove; in bogs near Kings River; Mt. Dana, Mt. 

 Brewer, Upper Tuolumne Caflon, Yosemite Valley in the spray 

 of Vernal Falls. The following instructions for collecting' and 

 preserving should be noted. They may be expected anywhere 

 in cold bogs: 



" All the plants for one series of sixty specimens should be 

 gathered at one time and place, to avoid the chance of mixing 

 two different forms under one number. The plants of dense 

 habit of growth should be separated into broad, thin specimens 

 while fresh, cleaned of foreign matter, and preserved in botan- 

 izing portfolios in the usual manner, taking care not to subject ihem 

 to any severe compression . Just enough pressure to keep them flat is 

 enough. Floating plants, such as the plumose forms of .5. cus- 

 pidatum, are best prepared by spreading the specimens on letter- 

 paper, as is usual in preserving the more delicate seaweeds. If 

 the collector has no means of pressing the specimens, they may 

 be gathered in bulk, and, when air-dried, .sent in packages to 

 Professor Eaton, who can have them softened and spread out for 

 drying at some convenient time. Care should be taken to note 

 the place and time of each collecting, and the approximate 

 height of the station above sea-level." 



Professor C. H. Gilbert and Professor O P. Jenkins, of the 

 Stanford University, have joined Dr. Barton W. Evermann, of 

 the U. S. Fish Commission, in an expedition to examine the 

 headwaters of the Columbia in regard to the fish fauna, the 

 obstructions to the ascent of salmon, and the location of a 

 salmon hatchery. 



Professor W. E. Ritter, of the State University, has spent a 

 part of his vacation in making, with the assistance of several 

 of his students, a biological reconnoisance of Santa Catalina 

 Island. 



Professor C. H. Tyler-Townsend, of the Agricultural Col- 

 lege, Las Cruces, New Mexico, has taken the position of Curator 

 of the Scientific In.stitute at Kingston, Jamaica.
