of a good size, and our severe winters have killed many fine 

 specimens. In the south of England, in Ireland, and in the south- 

 west coast of Scotland, many grand specimens are growing and 

 thriving well. 



P. Jeffreyi (Jeffrey's Pine). — Introduced in 1852. Habitat, 

 the Shasta Valley in California. This pine very much resembles 

 Finns ponderosa ; and, like the latter, it is perfectly hardy, and 

 has leaves about 8 or 9 inches long. Its wood is also valuable, 

 and the tx'ee ornamental. 



F. Lamhertiana (the Sugar Pine). — Introduced in 1827. 

 Habitat, California and north-west of America. Grown under 

 favourable circumstances in its native habitat, a tree which had 

 been blown down was found to be 215 feet in length, and girthed 

 16 feet. In addition to its value as timber, which is good, and 

 its ornamental efiect, its seeds, which have a sugary taste (hence 

 the common name), are used as food. 



P. Laricio (the Corsican Pine). — Introduced in 1759. Habitat, 

 Corsica, Spain, Italy, Greece, Germany, and the Caucasus, where 

 it grows from GO to 150 feet high, with a proportionate girth. 

 It is a free growing tree when once established, but difficult to 

 transplant when of any size. Its branches grow in regular whorls, 

 with leaves of a cheerful green. Its wood is of fair quality, and 

 it is a good ornamental tree. 



There are several varieties of P. Laricio, such as P. L. 

 CaraTuanica, compacta, contorta, nana, pendula, and others, all 

 of which are curious or ornamental, and deserve a place in large 

 collections of choice trees. 



P. macrocarpa (the Large-coned, or Coulter's Pine). — Introduced 

 in 1832. Habitat, California; gi'owing in 36° of latitude, at an 

 elevation of 3000 to 4000 feet. It attains a height of 100 feet, 

 and a girth of 9 to 12 feet. Kemarkable for the size of its cones, 

 which are sometimes 14 inches long and 6 in diameter. The large 

 seeds are edible. If moderately sheltered, and grown on a dry, 

 porous soil, it is perfectly hardy in this country, and is a good 

 ornamental pine. Also known as P. CouUeri. 



P. initis (the Yellow Pine). — Introduced in 1739. Habitat, 

 New England States and Georgia, North America. This is the pine 

 which produces the valuable " yellow pine " timber of commerce. 

 The tree does not often exceed 80 feet in height. Although 

 ])0ssessing no special ornamental property, it should be planted 

 for the sake of its timber. Its habit of growth very much
