Notes of travel in the E side of Sierra From Truckee, Walker River, Carson mtns etc Nut Pine Wild Sheep Abies concolor [Picea Grandis] 4 ft dia [diameter] 457 yrs old 8000 ft elevation ab [above] sea on trib [tributary] of the Truckee above Bronco. This is considerably older than firs of the same dia growing on richer moraine soils at lower points on the South & mid portion of the range, & I notice that the same slowness of growth & greater longevity is common to the magnifica & the pines also. In the cases of all trees that have to suffer hunger or severer cold in youth the growth is of course slow, otherwise the woodrings show a more rapid growth in youth gradually diminishing in old age. This diminution of the thickness of the rings does not however always indicate a corresponding lowering of the vigor of the tree because the surface over wh the wood layer is laid increases more rapidly
