TREE PLANTING IN UTAH. 231 



cold; is said to attain a large size and to live long-, and has con- 

 siderable merit for ornamental planting-. With these qualities, 

 the Siberian Poplar can be recommended as a valuable tree to 

 plant. The specimens in the collection here, average 37 feet 

 hig-h and 29 inches in circumference. Its heavy foliage gives it 

 an air of durability that any other poplar, which we know, 

 lacks. It grows from cuttings. 



Petrovski Poplar. (Popukts laurifolia Led.) Known also 

 as the Certinensis Poplar. Bailey and Green give this poplar 

 credit for being the best of the Russian introductions. But 

 on our grounds, its merits are not so apparent as are those of 

 the Siberian Poplar. It is a more rapid grower, but its habit 

 and foliage do not fit it nearly so well for the shade and shelter 

 for which these trees would be largely planted, and we doubt if 

 there is much difference in the value of the timber of the two 

 species. Both sorts endure extremes of heat and cold per- 

 fectly, and both resist drouth better than any other poplars in 

 our plantation, a fact well shown last season, when they 

 suffered least of all when irrigation was withheld. In form 

 it differs much from the Siberian, having a more upright habit. 

 The leaves are thick and heavy, broadly ovate in form, dark 

 green in color, with a finely toothed margin, and with short, thick, 

 stiff leaf-stocks. The small shoots are covered with down. 

 Our specimens average 40 feet in height and 41| inches in cir- 

 cumference. This poplar, like the preceding one, deserves to 

 be introduced and thoroughly tried on the farms of this region. 

 Eastern nurserymen, and possibly some of the local ones, offer 

 several Russian poplars. 



THE WILLOWS. 



For a general purpose, all-around, useful tree, the willows 

 have more merit by far than they are given credit for having. 

 Their dense, tough growth especially fits them for wind breaks; 

 their tenacious roots serve well to hold the soil on banks of 

 rivers, canals, ditches and railway embankments; the wood is 

 light, tough and elastic and serves for many purposes about the 

 farm, for which that of no other tree will answer so well. The 

 wood of some species is highly esteemed for turnery, cooper- 

 age, bats, in carriage making, handles for tools, etc. For all these 

 purposes, willows can be grown in Utah. Osier willows for 

 basket-making and tying purposes, are now being grown some-
