Calif ornia juniper (Juniperus calif arnica). This tree had not been observed in the 

 Sierras north of Kernville on Kern River until Geo. B. Sudworth found it grow- 

 ing abundantly as far up the South Fork of Kern River as 7 miles below Monache 

 Meadow. 



Goldenleaf chinquapin (Caxlanea chrywphylla). Heretofore this tree has not been 

 known in Oregon except on the Cascade Range, but J. B. Leiberg found it in 1899 as 

 a shrub on the Klamath-Des Chutes divide to the east, and W. T. Cox discovered it 

 in 1903 in the southern Coast Range of Oregon in the present Siskiyou National 

 Forest, The extension is of very great interest. 



Garry oak (Quercus garryana) . Previously not known east of Trinity National 

 Forest, this tree was reported by A. R. Powers in the foothills of the Plumas, Diamond 

 Mountain, and Lassen Peak National Forests. Further careful field observations are 

 likely to reveal other outlying stations. 



Engelmann oak (Quercus engelmanni). E. A. Mearns (not of the Forest Service) 

 has very recently reported this species occurring a short distance beyond the Mexi- 

 can line, in lower California. Heretofore it has not been known farther south than 

 the mesa back of San Diego. 



Blue oak (Quercus doug/asii). Blue oak was reported by F. G. Plummer and M. G. 

 Gowsell in 1905, and by J. H. Hatton in 1906, in the southern California Coast Ranges, 

 in the watersheds of the Santa Ynez and Santa Maria rivers of the northwestern 

 part of the Santa Barbara National Forest, a locality in which it has not been 

 previously known. It is known, however, to occur a little farther north in the 

 northern part of the San Luis Obispo National Forest on the northern slopes of the 

 Sierra Liebre range, and in San Fernando Valley on the southern slopes of the San 

 Gabriel Mountains. Specimens or notes from this general locality are greatly 

 desired, as well as information concerning the northern extent of this oak in the 

 Sacramento Valley and in the Coast Ranges, where it is known at present only as far 

 as Redding and Mendocino County. 



Notes and Specimens Desired 



The Coast Ranges of Oregon and southern California have not been carefully 

 explored for the little known or unknown trees which they doubtless contain. In 

 Oregon the exact northern limit in the Coast Ranges of sugar pine, white fir (Abies 

 concolor), goldenleaf chinquapin, California black oak, and a number of other trees, 

 is unknown, while in California the exact southern limits of such Coast species as 

 Sitka spruce, western hemlock ( Tsuga Jielerophylla), yellow cedar, and Law r son's 

 cypress, as well as the western or northern limits of various California oaks and 

 junipers, are all yet to be determined. It is hoped that National Forest officers and 

 others will assist in completing our knowledge of the range of these trees by contrib- 

 uting notes and specimens.

Check Scaling 1 Results 



The work of check scaling on the Black Hills National Forest conducted by Assist- 

 ant Lumberman Hamilton, under the direction of Supervisor Smith, has shown that 

 in the cases of two of the officers the check scale varied from the original scale only 

 one-tenth of 1 per cent. This accurate work is to be highly commended, and it is 

 hoped that the check scaling on other Forests will show equally good results.
