534 ACCLIMATIZATION OF FOREIGN TREES AND PLANTS. 
damaged by the nipping easterly winds, but this occurs only 
in unfavorable seasons; and even if the tree never flowered 
at all, its lovely foliage would still make it one of the most 
beautiful evergreens of which our gardens can boast. A 
plant of the variety Donkelarii has stood out for twelve 
years in a garden at Forest Hill with a northern aspect, 
without the slightest protection during the severest winters, 
and now forms a good-sized bush, densely clothed with mag- 
nificent foliage. "The Camellia ought to be planted out in 
every garden, and with a little attention for the first year or 
two, it would prove quite hardy, at least in the more south- 
ern — and each season it — increase in attractive- 
ness.” 
The climate of the south of Blip is far more congenial 
to the introduction of foreign trees and shrubs than that of 
the northern counties, not from the greater severity of the 
winters in the north, for the minimum temperature of the 
year is often as low in Kent or Hampshire as in Yorkshire 
or Northumberland, but from the shorter and cooler sum- 
mers. Many plants absolutely require a considerable per iod 
of high temperature to enable them to ripen their wood suf- 
, fiiently to withstand the winter frosts, and especially to 
induce them to flower. In many parts of Scotland, how- 
ever, the climate is as favorable to horticulturists as in any 
district in England. In the Duke of Sutherland's estate at 
Dunrobin, on the east coast of Sutherlandshire, Hydrangeas, 
myrtles, and other half-hardy plants, grow as freely and as 
unchecked out of doors as they do in Devonshire or Corn- 
wall. The equalizing effect of the Gulf Stream on the tem- 
perature is no doubt the cause of this special immunity from 
frost. The proximity of the sea-coast is not generally fav- 
orable to the growth of trees and shrubs, not so much from 
the saltness of the air as from the prevalence of high winds, 
which are very injurious to growing vegetation. Young and 
tender shoots which will bear a moderate amount of cold, 
will sometimes. be scorched as if by fire by a tempestuous 
night. — The. Quarterly Journal of Science.
