to the Bighorns and southward as far as Bozeman and the Big Hole River. Its 

 occurrence farther south, however, in the more western mountains and on the east- 

 ern lowlands of the Missouri and Yellowstone rivers is extremely doubtful. It has 

 been observed in the northern mountains of Idaho, and possibly it extends to the 

 ranges north of the Snake River Valley, yet positive proof of its occurrence there is 

 lacking, as are also definite records for it in Nevada, Oregon, and Washington, from 

 which it has been reported. 



Long supposed to exist in the coast region of Alaska and the valley of Mackenzie 

 River, balm-of-gilead has, through recent explorations of W. A. Langille and W. H. 

 Osgood, of the Biological Survey, been discovered in the coast of Alaska at Cook's 

 Inlet, to which it comes, from the Bering Sea forest, across the low base of the 

 Alaskan" Peninsula, They found it also on the north end of Kadiak Island and near 

 the passes at the head of Lynn Canal. It should be looked for carefully along 

 the seaward side of the coast ranges, where it has possibly been confused with 

 J'<)i,n/tix ti-irhnrnrj):i. Its northern range was lately extended above the Yukon 

 Valley through field investigations of W. J. Peters and F. C. Schrader, of the U. S. 

 Geological Survey, who discovered groves of this tree along the Anaktuvuk River 

 (latitude 69 20'), a branch of Colville River, in the Arctic watershed. This local- 

 ity, the northmost one known, is 75 miles from the Arctic Ocean. 



Toumt'i/ ( ><(k ( Quercus Toumeyi). Heretofore this little-known oak has been found 

 only in the Mule Mountains, southeastern Arizona. A new location for it, the Chi- 

 ricahua Mountains, was reported in 1906 by H. D. Burrall, and in 1907 by J. S. 

 Holmes. Mr. Holmes sent specimens of the tree to the Forest Herbarium with a 

 statement that it occurs on the northwestern end of the Chiricahuas, on the west 

 slope, at the head of Bonita Canyon and on White Tail Canyon, at elevations of 

 about 6,000 to 6,200 feet. 



Arizona MndrdTi'i (Ai'htitti* arizonica.} The Arizona madrona has heretofore been 

 known only in the Santa Catalina and Santa Rita mountains, southern Arizona, and 

 southward on the Sierras of Chihuahua, Mexico. Recently, however, a number of 

 new locations have been added in other mountains of southern Arizona. In 1894 

 Dr. N. L. Britton, of the New York Botanical Garden, and T. H. Kearney, of the 

 Bureau of Plant Industry, collected specimens at Fort Huachuca, where it was 

 recently observed also by R. S. Kellogg. Mr. Kellogg and H. D. Burrall reported 

 it from the Chiricahua Mountains, at elevations between 6,000 and 7,900 feet, while 

 Mr. Kellogg and W. R. Mattoon found this tree in Frye Canton, at 5,800 to 7,500 

 feet elevation, in the Mount Graham National Forest. 



BRANCH OF GRAZING. 



During the month of June, Mr. A. F. Potter, Assistant Forester, in charge of the 

 Branch of Grazing, will be engaged in conferences with supervisors in Colorado. 



All official letters from Forest officers should be addressed to the Forester, no matter 

 what officer signed the letters to which they are replies. (See page 9, Service Order 

 No. 106. ) Each letter should bear upon one subject or one case only. (See page 132 

 of " The Use Book.") 



Duplicates of Form 861 should be sent the Forester in all grazing trespass cases.
