_Abies Menziesii_, or Menzies’s spruce, usually called “Spruce” by lumbermen of the country, is botanically very similar to the species last described, but the cones are larger and the leaves sharper pointed. It bears a large quantity of cones, which are generally aggregated near the top, obscuring the foliage, and giving the trees a peculiar tawny appearance. The wood is light, white, and fine grained, and would rival that of the last named species but for the fact that the trunk has a number of slight curves, so that it is impossible to obtain good saw logs of sufficient length from it. Its habitat is along the cañons from seven to nine thousand feet altitude, and seems to end about where _A. Engelmanni_ begins. It is, however, a smaller tree, and less abundant. _Abies subalpina_ is of little value as a timber tree; the wood is soft and spongy, from which circumstance it is locally known as “Pumpkin pine”, but the more appropriate name of “White balsam” is also applied to distinguish it from _A. concolor_, which is called “Black balsam”. This species grows high up on the mountains and plateaus, generally from nine to eleven thousand feet. It is very tall, often attaining a height of 80 or 90 feet. Its trunk is straight and limbless for a great distance. This species has been but little known to botanists heretofore, from the fact that it has been confounded with _A. grandis_, but Mr. Engelmann decides, from specimens collected by Mr. L. F. Ward, that it must be considered as a new species. _Abies amabilis_ and _Abies grandis_, spruces resembling the “White balsam” in their general appearance, occur in the Wasatch Mountains, but are not abundant. _Juniperus Californicus_, var. _Utahensis_, or White cedar, is very abundant over the foot hills and lower mountain slopes, and, like the piñon pine, is much used for fire wood. It has also the characteristic durability of the junipers, and makes excellent fence posts. It grows low, is diffusely branched, and is valueless for milling purposes. _Juniperus Virginiana_, or Red cedar, is also found in this region. Its habitat is near the streams and at moderate altitudes. It is said to lack the durable qualities for which it is noted at the east, and which seem to be transferred to the other species. _Populus angustifolia_, or Cottonwood, is the chief representative of the poplar family in this region. The people of the country distinguish two varieties or species, the Black cottonwood and Yellow cottonwood. The former is said to be useless for lumber, while the latter has some slight value. It forms no part of the forest proper, but fringes the lower reaches of the streams, rarely occurring higher in altitude than 6,000 feet. Its rapid growth and its proximity to the irrigable lands make it valuable for fuel, although it is not of superior quality.
