In every part of our district, " very fine examples of this tree are 

 often met with, and, when growing in an appropriate situation, such 

 as on the hanks of a river, the margin of a purling brook, or in one 

 of our low, sheltered, and sunny haughs, it forms a heautiful and 

 interesting feature, its silvery and plume-Hke foliage giving an air of 

 lightness and grace to the landscape, and producing, by its contrast 

 with foliage of a deeper tint, that effect so agreeable to those who 

 view such scenes with the eye and feeling of an artist." P. J. Selby. 

 — Trunks of large trees of this species are exposed in the deep drain- 

 ing of some of our mosses.

 — " It grows in great abundance, and with every appearance of being 

 a native, upon the river of Eden at Mellerstain in the Merse; but has 

 undoubtedly been introduced, along with many other exotic trees, in 

 the plantations about that fine place. One tree of this sort, upon the 

 river below the house, was measured in September 1 79o and found 

 to be 4 feet 10 inches in circumference 4 feet above the ground, and 

 30 feet high." — " Brought originally from England or from abroad, 

 but long cultivated in Scotland as a basket Willow. It is probably a 

 native of the east, and perhaps of the southern parts of Europe." — 

 " Its brio-ht green foliage and its white bark render it one of the 

 most pleasing trees to the eye. It is therefore remarkably adapted 

 for ornamenting any marshy grounds, or the sides of lakes." Walker.
