shabby stag-horned look. One of the largest in the Park, 

 however, had a fine head of spreading foliage, and although 

 11 feet in girth, grew at the rate of no less than 0"69 

 for ten years. This is a rate not exceeded by any forest 

 tree of similar size and of wdiatever species that I have 

 measured, a proof that the Oak when of considerable size 

 is not invariablv a slow "rower.

Q. rnlra. Transplanted in spring 1887 to the grassy, free, 

 but sheltered space behind the gi'eat Yew in the Botanic 

 Garden. 



In consequence of transplantation, the foliage was miser- 

 ably poor in 1887, and the increase was only a tenth of an 

 inch. In 1888 the whole of the shoots of the previous year 

 died. The tree was almost leafless, and there was no girth- 

 increase. Apparently it was in a hopeless state. Nevertheless 

 it recovered perfectly, although slowly. In 1889 the leaves 

 were scanty, but large and healthy, and the increase was 

 0-30. Xext year it was 0'90; and in 1891, although a year 

 of general depression, it rose to I'OO, and the tree was 

 handsomely clothed. Hence the normal rate is probably 

 about an inch. 



Q. Cerris. Although much older than the other trees, it 

 was selected as the only available specimen of its species. It 

 is a fine tree, with a straight, tall, cylindrical stem and a fair 

 head of foliage, well situated south of the central open space 

 in the Botanic Garden. 



Its annual rate was 0'57, exactly the same as in No. 43 

 of the former set, also a Botanic Garden tree, which as to

 beginning and end of the period. These discrepancies arise fiom unimportant 

 causes, are trifling in amount, and are of no Tuoment as regards the results.
