ON TREES AND SHRUBS.

a beautiful shade of yellow, deepening to bronzy-brown before 

 they fall. This species is also attractive in winter on account 

 of the brownish-coloured bark of the young shoots, which at that 

 season are seen to excellent advantage. 



The Golden Larch cannot be depended upon to reproduce 

 itself from seed. The usual method of propagating it is by 

 grafting in early February on stocks of the Common Larch 

 (Z. europcea). Select young, well-ripened scions, about the thickness 

 of a lead-pencil. After they have been secured to the stock, 

 place them in a moderately warm case, and when a union has 

 taken place, remove to more airy quarters. 



Pseudotsuga Douglasii (Abies Douglasii, Picea Douglasii, 

 Tsuga Douglasii). — 

 Few Conifers are better 

 known or more exten- 

 sively planted than the 

 Douglas Fir, intro- 

 duced to this country 

 from North America, 

 in 1827. It is' a 

 splendid tree for the 

 park and landscape, 

 but shelter from east 

 winds is advisable. 

 It is of rapid growth, 

 and forms a pyra- 

 midal tree, varying in 

 height according to 

 soil and position. The 

 branches are hori- 

 zontal, and the small 

 branchlets are supplied with rich 

 green leaves. Its pendulous and 

 attractive cones (about 3m. long) 

 are borne freely on medium-sized 

 trees. P. D. brevifolia bears some 

 resemblance to the Silver Firs, and 

 is worthy of extended culture; it 

 is of pyramidal habit, and of slow 

 growth, with polished green leaves. 

 P. D. glauca is a pretty variety, 

 of close, compact habit, and with 

 beautiful glaucous leaves ; it grows 

 freely, keeps its colour well, and 

 is thoroughly hardy. P. D. pumila 



(Colorado variety) is a distinct variety of neat, compact growth. 

 Where low-growing Conifers are required, this one should find 

 a home. P. D. Stairii, which originated at Castle Kennedy,
