MAV, 1903. A LIST OF MAMMALS ELLIOT. 177 



Requa was the next place visited, considerably to the north of 

 Eureka, and situated on the Klamath River, which at its mouth Mr. 

 Heller states is "bordered by rather steep hills with occasional small 

 flats interspersed among them. Most of these hills are heavily 

 forested with Picea, Pseudotsuga and Sequoia. A few bald hills occur 

 which lack trees and support only a growth of ferns and bushes, but 

 these are found usually a considerable distance up the river. The 

 dominant tree about the mouth of the Klamath is Picea sitkensis, which 

 grows to an immense size on the rich bottom lands. The giant arbor- 

 vita; Thuya occidentalis finds its southern limit here and Tsuga hetero- 

 phylla is also quite abundant. All three of these trees are characteristic 

 of the Canadian zone in which the whole coast line is situated. Fifteen 

 or twenty miles inland the Transition zone occurs in which oaks and 

 Douglas fir predominate, and Picea and Sequoia are lacking. " Sea lions 

 are common off the coast and also in the Klamath River, which they 

 ascend for several miles to feed upon the salmon ; also seals, Phoca 

 richardi, are plentiful and destroy a great many salmon. At Requa 

 was first procured the wood-rat I have called Teonoma f. apicalis. 

 From Requa Mr. Heller went to Crescent City, type locality of Microtus 

 angusticeps, near the boundary line of California and Oregon, where he 

 remained eight days. He says of this place that it is "situated- in a 

 low level country, which extends from the hills five miles south of the 

 town to the mouth of Smith River a somewhat greater distance to the 

 north. The region contains a considerable number of lakes and is 

 generally swampy where not forested. Spruce and Douglas fir are the 

 commonest trees near the coast, but inland a few miles the redwood 

 forests extend unbroken north and south, and with a width of six to 

 ten miles. " 



Passing now into Oregon the first stop was at Goldbeach, where a 

 stay of one month was made. Of this place Mr. Heller writes that it 

 is "situated in a hilly region at the mouth of Rogue River/ The hills 

 rise abruptly from the river to heights ranging from five hundred to 

 fifteen hundred feet, their summits usually gently rounded or compara- 

 tively level, and composed largely of serpentine rock which supports 

 a fair growth of grass or brush, but few or no trees. The forests are 

 confined mainly to the caftons or hillsides, but are not absent from 

 the ridges where these are composed of soft rocks or soil. 



The forests consist chiefly of the Douglas fir, Pseudotsuga taxijolia. 

 Near the coast Abies amabilis, Picea sitkensis, and Pinus contorta form 

 a fair portion of the timbered areas. Away from the coast Chamce- 

 cyparis laii'soniana is a fairly common forest tree. The tan-bark oak, 

 California laurel, red alder, big leaf maple, and madrofto are common
