The wood is white, “soft lighh Se very resinous; it is more

a specimen that I have examined, from the locality which far. 
nished the specimen of Juniper referred to above, is five a 
one-half inches in diameter and shows one hundred and thirteen 
annual layers of growth. The immense crops of large and deli- 
cately flavored seeds produced by this tree supply, as is well 
known, to the Indian tribes of the Great Basin their most im 
tant article of food. The value of this crop, and the exceliout 
quality of the wood for charcoal, make this tree, in a mining 
region entirely destitute of coal, its most valuable vegetable 
production. The introduction of Pinus monophylla into the 
age—and the pleasing glaucous tints o oliage commend 
this species to the lovers of ornamental co nife ers. 
Pinus Balfouriana* was only met with on Prospect Mountain, 
near Kureka, at an elevation of 7,500 feet, to the summit, 8,000 
generally covered with this species, but with few exceptions 
the trees have all been cut to supply the mines with timbering, 
for which purpose the strong and very close-grained, toug 
wood of this species is preferred to that of any “other Nevada 
— The specimens seen were fifteen to thirty feet high, with 
runks often two feet in diameter, pyramidal in outline, their 
. branches still remaining; so that at a little distance they 
might readily be mistaken for spraces. The bark like the 
wood is reddish in color, very thick and deeply furrowed ; that
