and although there was a rally to I'OO the next two years, 

 it has not yet recovered its pristine look of vigour. Au 

 older tree, No. 31, began to fall off in appearance when 

 under 2 feet in girth, and, when a little above it, became 

 very thin in the branches and unsightly, and was cut down 

 in 1887. Notwithstanding its shabby look, its rate for the 

 last five years was 1"02. 



No. 91. Abies grandis. No. "24. Abies Hookeriana. 



Ah. grandis. In the Abies collection, very healthy, densely 

 clothed to the ground. The annual rate has been 1| inch, 

 and the range, 1*15 to 1*80, is moderate. Numerous vesicles 

 appeared on the stem in 1891, but there has been no 

 exudation of turpentine. 



Ah. Hookericma. A bushy, well-clothed tree, with an up- 

 right habit, on the west side of the Ahies collection, with a 

 rate of 0"59 and the moderate range of from 0'50 to 0"70. 



PiNUS EXCELSA. 



Nos. 2 and 3 are in the collection of Pinus, and No. 11 on 

 " the Triangle." 



No. 2 is three-quarters closely surrounded and over- 

 shadowed, but not touched by other trees. It seems quite 

 healthy, but is short-branched ; its rate, I'OS, is probably fair 

 for so young a tree, and the range, 0'90 to 1-20, is small. 



No. 3, near the last and similarly situated, but more over- 

 shadowed and pressed by neighbours, has still shorter branches 

 and is more straggling though symmetrical. Its rate, 0*57, 

 little more than half that of No. 2, must be exceptionally low.
