number 14 genera or families, comprising 70 species 
or kinds of trees—13 of the genera with 40 species 
being in California. 
Of these species 27 are pines, 2 are larches, 5 are 
spruces, 2 are hemlock spruces, 2 are false hemlock 
spruces, 10 are firs, 2 are redwoods, 2 are American 
cedars, 7 are cypresses, 9 are junipers, and 2 are 
yews. 
KNORMOUS SIZE OF TREES AND CONES. 
Three of our pines—the great Sugar, the Yellow, 
and the Jeffrey Pine—all of them being very val¬ 
uable trees, are also the largest trees of the family, 
often attaining a height of 220 feet, with a diameter 
of 10-12 feet—110 pines of foreign countries attain 
one-half of these dimensions. 
Five of our pines bear longer or heavier cones, 
with larger seeds than any found elsewhere, the 
cones of the very valuable Sugar Pine being 15-20 
inches long, while those of the Coulter Pine often 
weigh 8-10 pounds, the Gray Pine 3-4 pounds, the 
Torrey Pine 2 pounds, and the Jeffrey Pine y 2 -2 
pounds, while the largest cones outside of Cali¬ 
fornia scarcely exceed 6 inches and the heaviest 
rarely weigh 1 pound. 
Two of our spruces attain enormous dimensions 
—the very beautiful and valuable Douglas Spruce 
of the Sierra and northward becomes 300-450 feet 
high, with a trunk 8-12 feet thick. The great 
Tideland Spruce of the north coast is but little less 
in dimensions, while the cone of the Big-cone 
Hemlock Spruce of the San Bernardino Mountains 
is 5-7 inches long and 3-4 inches thick when ripe
