In the coast mountains it is a fine, tall, rather slender tree, about from sixty to seventy-five feet high, growing with the grand _Sequoia sempervirens_, or Redwood.

But unfortunately it is too good to live, and is now being rapidly destroyed for tan-bark.
Besides the common Douglas Oak and the grand _Quercus Wislizeni_ of the foot-hills, and several small ones that make dense growths of chaparral, there are two mountain-oaks that grow with the pines up to an elevation of about 5000 feet above the sea, and greatly enhance the beauty of the yosemite parks.

These are the Mountain Live Oak and the Kellogg Oak, named in honor of the admirable botanical pioneer of California.

Kellogg's Oak (_Quercus Kelloggii_) is a firm, bright, beautiful tree, reaching a height of sixty feet, four to seven feet in diameter, with wide-spreading branches, and growing at an elevation of from 3000 to 5000 feet in sunny valleys and flats among the evergreens, and higher in a dwarfed state.

In the cliff-bound parks about 4000 feet above the sea it is so abundant and effective it might fairly be called the Yosemite Oak.
