have been planted in masses within the present century, and never in theslightest degree pruned, and which have yet straight stems, upwards of 60 ft.high. The largest tree of Q. sessiliflora now standing in England, that wehave had any account of, is that in Studley Park, Yorkshire, of which fig. 1585.is a portrait, to the scale of 1 in. to 30 ft., and which is 118 ft. high. Thehighest existing tree of Q. pedunculata, that we have heard of, is one atTibberton Park, in Herefordshire, of which fig. 1587. is a portrait, to thescale of 1 in. to 50 ft., and which is 108 ft. high.

It is not known that there is any difference in the longevity of thetwo kinds; there being examples of both which must be upwards of 200 or300 years old. There are several oaks in England which are from 500 to1000 years old, or upwards; but, in most cases, we have not been able toascertain to which species they belong.

Geography. The British oak is a native of most parts of Europe, fromSweden to the Mediterranean ; of the north of Africa; and of the west ofAsia: and Q. pedunculata appears to be the more prevalent species; especiallyin the middle and northern regions. In Britain, the Q. pedunculata is by farthe more common: but Q. sessiliflora is found in various places throughoutthe island; for example, in addition to those already mentioned (p. 1736.),near Cuckfield, at Cowfold, and in different parts of St. Leonard’s Forest,at Coalhurst near Horsham, and at Goodwood, in Sussex. Mr. Borrer,who has given us these localities, adds : “ There is abundance of it aboutTunbridge; and I particularly recollect it near Dalgelly; and in profusion,and varying much in its foliage, in some parts of Devonshire, and espe~
