valuable for lumber that, except in inaccessible places, the best trees 
have been cut. The huge trunks, often 6 or 7 feet in diameter, rise as 
straight symmetrical pillars to a height of 150 or 200 feet, and are coy- 
ered with fine beautiful bark. The long and graceful branches are 
usually confined to the upper parts of the trees, and the cones they 
carry are the longest known, frequently attaining a length of a foot and 
a half aud sometimes of 2 feet. They are very light, however, and 
when falling are by no means 
so dangerous to the passer [|

they cease at an aititude of

fairly common in McCloud 
Valley and at Sisson, whence 
they extend south along the 
Sacramento Canyon to ‘The 
Loop. They are at present 
more abundant in the neigh- 
borhood of Black Butte than 
elsewhere about the moun- 
tain. In the Shasta region 
they are not so large as on 
the west slope of the Sierra 
in central California; still

KNOBCONE PINE (Pinus attenuata, fig. 17) —The knobeone pine is 
a tree of erratic distribution. On Shasta it is confined to the lower 
slopes on the south side, from Panther Creek easterly to a point 
between the branches of Mud Creek, where it ranges irregularly from 
an altitude of 3,800 up to 5,600 feet. The latter limit is attained in a 
gully a little east of Wagon Camp, in a continuation of the Panther 
Creek strip. Lower down on Panther Creek, where the original forest 
of ponderosa and sugar pines has been removed by the combined work 
of lumbermen and forest fires, and the slopes are now covered by 
an impenetrable jungle of manzanita, this singular pine remains, com-
