TREK PLANTING IN UTAH. 225 



easily from cutting's, and thrives where a tree of almost any kind 

 can be grown. 



In this experiment the Carolina Poplar has proved to be per- 

 fectly hardy, very thrifty, and is a fairly handsome tree. In 

 their nine years of growth the trees have reached an average 

 height of 39 feet, and have attained a circumference of 40 inches. 

 The wood is soft, dark brown in color, and weighs 24 pounds 

 per cubic foot. Fig-. 3 and the row of trees at the left in the cut 

 on the front cover, show the character of the Carolina Poplar 

 very well. This is probably the best species of poplar for gen- 

 eral planting- in this region. 



To farmers living- where coal is expensive, or must be hauled 

 a great distance, and where timber for fuel is getting scarce, a 

 matter of paramount importance is to plant trees of some sort 

 in such quantities that a supply of timber for fuel can be had. 

 Though the wood does not make the best fuel, yet, all things 

 considered, no tree is better adapted for this purpose in Utah, 

 than the Carolina Poplar. Its qualities, as given above, fit it 

 pre-eminently for this purpose. In growing the trees in a wood- 

 lot, cuttings, either rooted or unrooted, should be set in rows 

 eight or ten feet apart and half that distance from each other in 

 the row; the trees to be thinned when poles large enough for 

 firewood are produced. The young forest will require careful 

 attention in tillage and watering the first year. Fig. 4 shows a 

 two-acre wood -lot of this description that will produce fuel 

 enough to keep a farmer in firewood for ten or twelve years. 



Bolleana Poplar. {Populus alba bolleana Lauche.) Known 

 also as Bolle's Poplar. This poplar has proved itself to be 

 quite as hardy and almost as thrifty as the Carolina. In growth, 

 during the same number of years, it has reached a few feet 

 greater stature, 43 feet, but not quite so great a circumfer- 

 ence, 29 inches, as the preceding poplar. In shape, the Bol- 

 leana is much like the more common Lombardy, but differs much 

 from it in color of foliage and trunk, being in respect to color 

 of foliage more like the Silver Poplar and having a hue dis- 

 tinctive to itself for its trunk. It makes a cleaner growth, a 

 more symmetrical, spire-like top, sprouts less, and lives longer 

 than the Lombardy, with which it is so often compared. Its 

 narrow top makes it a poorer shade tree than the Carolina, and 

 ts white foliage and greenish-white shoots and shaft, are a
