TRANSACTIONS 
OF THE 
ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
XI. Address delivered at the Thirty-eighth Annual Meeting, 4th 
August 1891. By Isaac Bayutey Batrour, 8c.D., M.D., 
F.R.S., Queen’s Botanist in Scotland, Professor of Botany 
in the University of Edinburgh, and Keeper of the Royal 
Botanic Garden. 
Our annual meeting, of which we to-day inaugurate the thirty-

of reviewing our position with reference to the aims for the 
attainment of which we were incorporated, of considering how far 
we have progressed towards an immediate goal, and of discussing 
the lines along which we may hope to make further advance in 
the near future ; and it has appeared to me, therefore, that it would 
be fitting were I from this chair on this occasion to say something 
regarding matters which have very particularly engrossed the 
attention of the Representative Council of the Society during the 
past year, and which it is certain will demand even more attention 
during the forthcoming one. 
Into any retrospect of the work of a Society such as ours, there 
must always enter an element of sadness, As one anniversary 
after another comes round, and we measure our progress, we are 
conscious of gaps in the ranks of our comrades in work. Some 
veterans, or it may be youthful members, are no longer here to 
answer to the roll-call. And amongst those whom we miss at 
this annual meeting is one, the doyen of Scottish foresters, by 
whose death the Society has lost one of its oldest and most valued 
members. It is difficult to estimate the services which Mr William 
M‘Corquodale rendered to forestry and to this Society. His
