PARKS AND PLEASURE-GROUNDS. 



124, 128 are large, spreading, and irregular ; of 123, horizontal, spread- 

 ing, and twisted ; of 125, loose and robust ; of 130, few and horizontal, 

 in regular whorls ; of 129 and 132, densely set. The colour of 125 is a 

 silvery green; of 124 glaucous ; of 115, 116, 123, hght green; of 121 

 and 129, vivid green ; and of 126, 128, 130, dark green. The length 

 of the leaves varies generally from 2 to 8 iaches, but ia 124, 125, 128, 

 130, it ranges from 10 to 12 iaches. P. insignis, Sahinima, macro- 

 carpa, and ponderosa are of very rapid growth. P. Tcsda, radiata, 

 and tuberculata stand the sea-breeze weU in their native countries, 

 and are expected to prove acquisitions to parks near the sea-coast ia the 

 United Kingdom, P. Sahiniana requires a rich loam; Gerardiana 

 thrives amongst rocks and crags ; Tceda, ia very barren ground, but 

 attains its greatest perfection in swampy soils. P. indgnis and rigida 

 afford effective shelter. The timber of P. rigida is valuable, and that of 

 P. ponderosa is expected to prove so. The hght silvery colom^ of P. 

 Sahiniana and maorocarpa will be as marked in ornamental scenery 

 during the whole year, as the summer garb of the Himtiagdon willow ; 

 and the hght greens of P. Teocote, patula, and Gerardiana, as that of 

 the simuner greens of the deciduous trees.
