The depression in girth-increase was evidently severe the 

 first year after transplantation, and continued, although to a 

 less extent, next year, but appeared to be at an end in 1889. 



No. 90. Rdinospora ohtiisa. Girth 3'05 inches 1 inch 

 above ground in spring 1887 ; was transplanted in the 

 following spring. No apparent effect on the healthy foliage. 



Although the shrub looks perfectly healthy and vigorous, 

 yet the average rate of girth-increase for four years after 

 transplantation has been only 0"15 inch, or one-third of the 

 amount in the year before transplantation. 



General Bcmarhs. It is possible that the effects of trans- 

 plantation in some of these instances were unusually unfavour- 

 able, as the early part of the season of 1887 was very dry. 

 It is remarkable that although the falling off in girth-increase 

 might generally be predicated from the poor condition of the 

 foliage, yet in some instances there was no apparent relation of 

 the kind between the two. Thus in AUcs Douglasii, No. 60, 

 although the foliage was exceedingly poor in 1889, and had not 

 improved much in 1890, nevertheless the girth-increase in the 

 former year sprang up from 045 of the previous depression to 

 1"20, and this rate was fully maintained in 1890 — probably 

 a normal rate for a tree of its age. Again, in Bctino&pora 

 obtusa, No. 90, the foliage seemed absolutely unaffected by 

 transplantation, but the girth -increase for four successive years 

 lias been reduced to an average of one-third of the rate in 

 the year previous to transj)lantation. 



A very shabby appearance in a tree even for some years 

 after transplantation should not cause despair as to ultimate 

 perfect recovery. Sir Eobert Christison was informed by 

 the elder Mr Macnab that the large Yew, now 6 feet in girth, 

 and one of the chief ornaments of the Botanic Garden, took 

 many years to recover from its third transplantation to its
