258 BULLBTIN NO. 62. 



While, unfortunately, we have no old specimens of the latter 

 species on the grounds, yet in the new experiment the Scotch 

 Pines have proved much the easier to handle and are more re- 

 sistant of drouth. They are, too, far more rapid growers and 

 more robust trees. To the eye of the cultivator, the Austrian 

 differs from the Scotch Pine, in having- a more spreading- habit 

 of growth, and coarser, longer, darker green needles. So far 

 as our new plantation now shows, the Austrian is next best to 

 the Scotch Pine for this region. A fuller trial may prove the 

 Bull Pine to be equal of either. 



Blue Spruce. (Picea pungens Engel.) A native of Utah 

 known in the State as Parry's Spruce and Colorado Blue 

 Spruce. For an ornamental evergreen, this is, perhaps, the 

 best of all for this State. In its natural environment, thriving 

 in any moist, well drained soil, exceedingly beautiful and attrac- 

 tive, it would be hard indeed to find for this region an ornamen- 

 tal that would surpass or equal it. Our specimens have 

 attained an average height of 15 feet and a circumference of 12 

 inches. Fig. 11, shows a Blue Spruce removed from the 

 experimental plat last winter to the College campus; as the cut 

 shows, it is a very handsome tree for the lawn. 



The Blue Spruce at maturity reaches a height of 100 feet, 

 is very tall in proportion to its circumference, and is spire-like in 

 shape, with very short branches. The foliage has a beautiful, 

 blueish tint which gives the tree its name. This fine coloring 

 is especially noticeable in young specimens and in these it is apt 

 to be somewhat variable; in older trees the foliage assumes a 

 deeper green and a less variable cast. The bark is thin, except 

 at the base of the tree, and of a brownish color; the twigs vary 

 from brown to yellow, depending on their age. The cones are 

 about three inches long and half as wide, cylindric in shape, 

 and light yellow in color. The wood is of value for lumber and 

 paper. 



This tree is a favorite one in Utah, and in the Eastern 

 States and in Europe as well, for ornamental planting, and 

 well deserves its popularity. Judging from experience on these 

 grounds it is not at all a difficult tree to transplant, and when 

 young can easily be brought down from its home in the moun- 

 tains. Its greatest defect is, that with old age it becomes 

 ragged and unkempt, showing all the marks of old age.
