scattered trees in San Luis Obispo County on the north and south ridges between 

 the Carisso Plains and the valleys where San Luis Obispo and Arroyo Grande are 

 situated. Messrs. Plummer, Goswell, Hatton, and Sterling recently noted it in the 

 Santa Barbara Reserve east of Pine Mountain between Thorn Meadows and Pine 

 Mountain Lodge, and in part of the Alamo Mountain region. It was also seen by 

 Mr. Hatton in the San Gabriel Mountains on Mount Wilson, Pine and Brown Flats, 

 etc., and forming a timber forest from the head of Sheep Creek throughout the 

 Upper Swarthout Valley on to some of the higher portions of the San Gabriel and 

 San Antonio watersheds, as well as in the vicinity of Mount Gleason, in the eastern 

 part of the San Gabriel Reserve. R.. D. Craig reports that in the San Bernardino 

 Mountains yellow pine forms the main stand from Little Bear Valley to Sawpit 

 Canyon and occurs less abundantly nearly to Cleghorn Pass and Deep Creek. A 

 range not previously published and just reported by Mr. Flintham for northeastern 

 California is in the northern part of Modoc Reserve, on the Shafer and Warner 

 mountains, and extending from the latter range into Surprise Valley at an elevation 

 of 4,800 feet to within a few miles of the Nevada line. 



Limber pine (Pinus fexilis}. Two additional new stations for this pine in southern 

 Idaho, west of the Continental Divide, have just been reported by A. E. Oman, 

 forest assistant. One is near the headwaters of Cub and Maple creeks, at an eleva- 

 tion of 7,500 to 8,000 feet, in the Bear River Reserve, and the other is on the summit 

 of Oxford Peak, in the same reserve, at an altitude of 9,000 to 9,500 feet. 



Bristle-coif", pine (Pinus aristata). Heretofore the southern limit has been in the 

 Culebra Range of Colorado. J. H. Hatton has, however, recently reported that this 

 pine extends southward over the northern part of New Mexico, and H. P. Baker 

 also reports it at 11,000 feet elevation on slopes just below Pecos Baldy Pass in the 

 Pecos River Reserve. 



Lodgepole pine (Pinus murraijana). It is surprising that up to the present time no 

 record has been published of the occurrence of lodgepole pine as far east as the 

 Black Hills, South Dakota, the nearest point being several hundred miles farther 

 west. Henry S. Graves supplied the first record of its presence in the southeastern 

 part of the Black Hills by a photograph he took in 1897 of a tree 3 feet in diameter on 

 Squaw Creek. Recently R. P. Imes, technical forest assistant, reported having 

 found a stand of about 40,000 feet of lodgepole pine in sec. 5, T. 2 N., R. 2 E.; also a 

 medium-sized group in sec. 29, T. 3 N., R. 3 PI, and a single tree in the northeast 

 quarter section of sec. 27, T. 3 N., R. 3 E. 



Sitka spruce. (Picea sitchensis). The southmost station now known for this tree is 

 Fort Bragg, on the Mendocino County coast, recently reported by S. J. Flintham. 

 It is hoped that further careful search will be made in this region, where the range of 

 Sitka spruce is believed to be still imperfectly known. 



Weeping spruce (Picea breweriana). Until recently this rare and little-known 

 spruce has been known to occur in the western part only of the Siskiyou Mountains, 

 in southern Oregon and northern California. It is supposed to have been found also 

 on Black Butte at the western base of Mount Shasta, in 1863, but it has not been seen 

 there since. Recently the range has been extended southward about 100 miles by 

 Miss Alice Eastwood, of the California Academy of Sciences, and by E. Koch, who 

 discovered groves on Canyon Creek (T. 35 N., R. 10 W.) in the southern Trinity 

 Mountains; while C. J. Buck, R. B. Wilson, and S. J. Flintham recently reported 

 weeping spruce on several mountain ridges in the Klamath and Trinity forest reserves, 

 from one of which specimens were sent to this office for identification. 



Further search should extend the range and, it is hoped, rediscover this spruce 

 near Mount Shasta, where Prof. W. H. Brewer found it so long ago. 



Tamarack (Larix laricina}. The long conjectured occurrence of tamarack in Alaska 

 is now confirmed by the explorations of L. B. Bishop, Biological Survey, and by L. 

 M. Prindleand A. F. Brooks, of the U. S. Geological Survey, who observed it on the
