1868) that he measured, in the Himalaya, a tree 
of this species which was upwards of forty feet

My eardener: Robert. .Pettit, has tried to 
propagate this species by grafting on A®sculus 
Hippocastanum and rubicunda; and it seems

(June, 1864). The tree in the arboretum, 
which I have so repeatedly mentioned, flowered 
very well last year; and this summer it has a 
greater abundance of thyrsas of flowers than it has 
ever yet shown. The blossoms are now beginning

between the stables and the east lodge, bore 
flowers last year for the first time, and has flowered 
again more abundantly in the early part of this

fruit last year, and four thriving young plants have
