182 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
Conservatory, and a lily pond and students’ garden, the party 
drove by Garrioch Bridge and Bilsland Drive to Ruchill Park, 
where some planting of an experimental kind is being carried 
out. Owing to the pollution of the atmosphere by gases from 
foundries, glass-works, etc., in the vicinity, only the hardiest of 
trees and shrubs will grow here, those which have been found 
to thrive best being species of Crategus and Pyrus, Cotoneaster 
Srigida, and Rosa rugosa, which, curiously enough, seem to do 
better here than in some other apparently more favoured 
situations in the city. The party next proceeded to Springburn 
Park, which has the highest altitude of all the city parks, 
and here again it was noted that thorn and /Pyvus were the 
trees which seemed to thrive best in the smoke-polluted city 
atmosphere. After an inspection of the fine Winter Garden the 
party resumed their drive, and passing through the north- 
eastern part of the city, where a number of the large locomotive 
engineering works, Parkhead Forge and St Rollox and other 
chemical works are situated, Tollcross Park was reached. 
Here attention was drawn to what might be described as three 
distinct generations of trees, the oldest of which are fast dying 
off owing to the effects produced by the underground workings. 
After a light refreshment, kindly provided by the Corporation, 
the party drove southwards, passing through Glasgow Green, 
where the difficulties attendant upon tree culture in cities are 
all too evident, to Queen’s Park. Here the atmospheric 
conditions are much more favourable, and the trees are, 
for a city, comparatively healthy; but in the old Caledonian 
Camp which covers the hill it was noted that the grove of 
beech was now showing marked disagreement with its environ- 
ment. An inspection of the Propagating Department, from 
which all the plants for decoration at municipal functions, 
etc., are supplied, finished this part of the tour, and a move 
was next made to the old garden and grounds of Camphill, 
where the last Cedar of Lebanon in the city grows; but the 
condition of this tree affords ample proof that evergreen conifers 
are ill-adapted to the smoky conditions which obtain in large 
cities. A drive through the residential district of Pollokshields 
by Maxwell Park to Bellahouston Park brought the tour to 
a close, and to those unacquainted with the city of Glasgow 
and its atmospheric conditions the afternoon’s outing was, 
especially from an arboricultural point of view, an extremely
