The Pine. Pinus Linn. The pines are found in most of the colder parts 

 of the world, where they cover immense areas. Few trees will endure 

 greater extremes of cold and the region of their natural habitat extends north to 

 Greenland. They are so constituted as to flourish upon poor, gravelly or sandy 

 soils, while their abundant and enduring- foliage, in its various shades of green 

 renders them of signal value in ornamental planting, whether used as shelter or 

 screen, or as a background against which to group deciduous trees and shrubs. 



White Pine. Pinus strobus Linn. As an ornamental tree the white pine is 

 probably the most valuable of the group, since its color is more cheerful and its 

 foliage more pliant and graceful than that of any other species. Unlike some of 

 the other pines, the shape of the tree does not become rounding at the top with in- 

 creasing years, but it permanently retains the form of a taper ing shaft. Making 

 a der.se growth, it is of great value in the formation of plantings for shelter and 

 protection. It is perhaps most graceful and beautiful when grown on thin, sandy 

 soil, as the tree then assumes a dignified, stately, spire-like form sometimes 150 

 feet tall, while if reared on land abounding in fertility the head is much more 

 dense. In rate of growth it is very rapid, hence of unusual value where speedy 

 results are wanted, as in the case of windbreaks and open screens. The great 

 white pine forests of North America are found in a belt extending across the 

 northern part of the United States and southern Canada. 



The Red Pine, sometimes called Norway pine (Pinus resinosa Ait. ), so named 

 on account of its attractive, bright red bark, is found native in New England 

 and the region extending northward through Canada and westward to Wis- 

 consin. The trees vary from SO to 75 feet in height and the wood is very rich in 

 resinous matter, being only excelled in this regard by that of the pitch pine. Its 

 habit of growth is peculiar in that the needles are borne in thick tufts on the 

 ends of the branches. These needles are long and of a dark green color and, as 

 they contrast well with the reddish bark, the tree is not an unattractive one. 

 While not of as great value from the ornamental standpoint as some of the other 

 pines, its distinctive habitof growth and hardiness entitle itto a place in collections. 



Western Yellow Pine. Pinus ponder os a Dougl. This species is found in 

 river valleys and on the lower mountain slopes along the Pacific coast, being 

 common in Oregon, where it often attains a height of one hundred feet with a 

 greater part of the trunk free from branches. It resembles the Austrian pine in 

 form, but is of a darker green and has long, glossy needles, which are borne in 

 plume-like clusters, While the appearance of the young tree is quite attractive* 

 the yellow pine will probably not be much used as an ornamental, on account of 

 the coarse and open appearance presented by the mature specimen, although its 

 vigor of growth and hardiness commend it for use in certain positions. 



Austrian or Black Pine. Pinus Austnaca Link. This la'rge speading species 

 is found native in Austria and adjacent countries. It is one of the irost widely 

 planted kinds and its merits have made it a general favorite. It has a massive 

 appearance and a symmetrical outline, due to its branches being placed equally 

 distant apart around the trunk, and as it is of a rich, dark green color, it is 

 very handsome as seen from a distance and harmonizes well with both white 

 and Scotch pines. However, an intimate examination will disclose a coarseness 

 which renders it unsuitable for planting near residences, although it makes a 

 satisfactory specimen when located in some remote site upon the lawn. For use 

 where an evergreen of strong, rapid growth, hardiness and adaptability to a 

 great diversity of soils is desired, the Austrian pine is one of the best trees to be 

 had. It is of exceptional value when used in shelter strips for protesting 

 orchards and buildings. While it does not grow so rapidly when young as the 

 Scotch pine, it lives to a greater ajfe, and will succeed in a moister soil than is 

 suited to most of the pines.
