trees in gulches of the Helena National Forest, Blue spruce has also been reported 

 from the ranges of southern Idaho (Sawtooth Mountains), and from eastern Wash- 

 ington and Oregon, but these stations are yet to be verified. 



Weeping Spruce (Picea breweriana) . P. T. Harris has just reported finding weep- 

 ing spruce on the head of Parks Creek, a tributary of Shasta River (T. 41 N., R. 6 

 W). This new locality is west of Mount Shasta on the Trinity-Shasta River divide, 

 and is approximately the region in which Prof. W. H. Brewer discovered weeping 

 spruce in 1863. The partial confirmation which Mr. Harris's discovery gives of 

 Professor Brewer's report, so long unverified, is of unusual interest. G. A. Coleman 

 and others report that groves of it are said to occur on the northern and eastern 

 sides of Mount Shasta, and it is hoped that these reports may soon be verified. 



Alpine Hemlock (Tsuga mertensiana) . S. N. L. Ellis reported three additional sta- 

 tions for this species in May, 1907, on the eastern slopes of the California Sierras. It 

 is quite common in Green Creek, Mono County (T. 2 N., R. 24 E. ), and near White 

 Mountain at the head of Silver King Creek (T. 7.N., R. 22 E.), points well down 

 the slopes of the mountains, while it was found in T. 8 N., R. 20 E., on the road 

 from Big Tree to Carson, Nev. A single -grove was found in February, 1907, by 

 P. B. Kenneday (not of the Forest Service) on the east side of the Sierras, above 

 Reno, Nev., on a north slope. 



Lowland Fir (Abies grandis). W. H. Kempfer has just reported, with specimens 

 for verification, lowland fir at Plains, Montana, on Clarkes Fork of the Columbia 

 River, north of the mouth of the Missoula River. This is another new point for 

 the southern range of lowland fir in Montana. Karl W. Woodward finds this fir 

 about Swan Lake, Montana, from which he has recently sent specimens, together 

 with those of Pinus monticola, P. murrayana, Picea canadensis, Pseudotsuga taxifolia, 

 Juniperus scopulorum, J. communis, Betula papyri/era, and Populus trichocarpa. 



Macnab Cypress ( Cupressus macnabiana}. A new intervening locality was discovered 

 for this tree in April, 1907, between the Lassen Butte National Forest stations and 

 the western end of the Siskiyou Mountains. P. T. Harris, who brought specimens 

 for identification, found the grove at a point about 15 miles north of Mount Shasta, 

 near Little Shasta River (Sec. 14, T. 45 N., R. 4 W. ), where, he says, the cypress grows 

 to a height of from 6 to 20 feet on " bare lava rocks, in pure stand, in dense thickets, 

 and in an open stand." This report verifies in part the prediction that Macnab 

 cypress would be discovered at a number of stations between the distant ones already 

 established. 



Port Or ford Cedar (Chanisecyparis lawsoniana). The range of this cedar is confined 

 mainly to a narrow belt on the seaward side of the coast ranges of southern Oregon 

 and northern California. It now seems probable that it extends eastward from its 

 principal range in many isolated stations. A few such localities are known for it, 

 such as one near Waldo, Josephine County, in the Siskiyou Mountains, Oregon. In 

 1899 a small grove was observed by M. C. Gannett on the headwaters of the Sacra- 

 mento River, near Sisson, at an elevation of about 3,500 feet. One grove was re- 

 cently seen also by P. T. Harris at the head of Halls Gulch (T. 37 N., R. 6 W.), a 

 tributary of the East Fork of Trinity River, and other groves were found by him 

 around Trinity Center at from 3,300 to 4,300 feet elevation. 



Black Cottonvood (Populus trichocarpa). The range of black cotton wood in Mon- 

 tana is still imperfectly known. Careful observations and specimens are needed to 

 establish its exact occurrence in this region. It is known to exist in a few places 

 only in the northern mountains, including Swan Lake, a station east of Flathead 

 Lake, from which Karl W. Woodward has just sent a specimen. 



Balm-of-Gilead ( Populus balsamifera) . The southern limit of this poplar in Montana 

 and Idaho has not yet been determined. It is mainly an eastern species which, in 

 the mountain valleys of both States, occurs with the narrow-leaf and black poplars, 

 while in Montana it extends eastward to the Little Rocky* Mountains, probably also
