of the ground, it actually wears out before it rots. The scent of the 



timber is delicious. I think if its wonderful durability were better 

 known in England it would be largely imported." 



The common Arbor Vitae is useful for belts and screens, and is one 

 of the best of Conifers for high hedges, in a moist soil, formed for 



protective purposes. On dry sandy land it becomes thin and unfur- 

 nished, and should, if planted at all, be only sparingly used. 



Thuia occidentalis Elwangeriana.— A dwarf dense bush, with 



numerous sub-erect branches, slender branchlets and dimorphous 



foliage. In one kind the leaves are linear, acute, and spreading ; 



"in the other they are scale-like and closely imbricated in four rows 



like those of the species. 



This variety is of American origin. 



Thuia occidentalis Hoveyi. — A dwarf compact variety, resembling 

 in habit Biota orientalis aurea, and having • short dense branchlets, 

 with foliage of a brighter colour than that of the common form. 



This variety is also of American origin. 



Thuia occidentalis lutea.— A self-coloured variety, the whole of 



the foliage and young growth being of a bright yellow above and 



orange-yellow beneath. It is of a lighter tint than the variety Ver- 

 vaeneana. 



It originated in the Nurseries of Messrs. Maxwell, of Geneva, New- 

 York, and is generally known in American gardens under the name of 

 George Peabody's Arbor Vitse. 



Thuia occidentalis pendula.— In this variety the principal 

 branches are recurved towards the trunk, and the branchlets are 

 tufted at their extremities. 



Thuia occidentalis variegata differs from the species only in 

 having many of the branchlets pale yellow. 



Thuia occidentalis Vervaeneana is one of the most distinct and 

 ornamental of all the varieties of the American Arbor Vitas. During 

 the growing season, all the branchlets, which are more slender than 

 in the species, are tinged with a deep golden-yellow, which changes 

 in winter to a brownish-orange. 



It originated in the Nursery of M. Vervaene, at Ghent.
