quantities are taken to the several world 
fairs, and are on exhibition in eastern and 
foreign museums. Grand trees are they, be¬ 
coming three to five feet in diameter in the 
San Bernardino Mountains. They extend 
northward along the Santa Lucia Mountains 
to San Luis Obispo, where they were first 
seen in 1830 by Dr. Coulter. An outlying 
grove of about 1,000 acres of small but beau¬ 
tiful trees ennobles Mount Diablo on the north 
side, in full view of the village of Clayton. 
To be seen at their best, the reader should 
visit the largest trees, holding out on their 
long limbs the great cones in pairs or trip¬ 
lets, when opened resembling wicker baskets. 
They are ten to twelve inches long, and weigh 
eight to ten pounds, by far the heaviest cones 
known. The scales terminate in hooks, curv¬ 
ing inward, the largest near the base on the 
outer side being often three to four inches 
long. The leaves, in threes, are almost un¬ 
excelled, fourteen to eighteen inches long. 
TWO CURIOUS PINES 
In strong contrast with these big Heavy- 
cone Pines is the little Knob-cone or Narrow- 
cone Pine (P. attenuata ), found in small 
groves at middle altitudes from the San Ber¬ 
nardino Mountains along the sunny slopes of 
the Sierra to Shasta, with several noted groves 
in the Coast Mountains, especially one large 
body on the summit of Mt. St. Helena, and 
a smaller on the eastern slope of the Oakland 
hills, but a few miles from that city. 
Usually small trees growing in masses, they 
become slender and tall, beginning to bear at 
an early age; the bright little cones, four to 
six inches long, are produced in circles, one 
marking each year’s growth, and hold fast 
on trunk and limbs, if the tree is separated
