18 A. G. Tansley. 
the party travelled to Truro. From Truro a local train was taken, 
and this was stopped by the kindness of the Great Western Railway 
Company on the line near Perranwell, so that the party could get as 
rapidly as possible to one of the best localities for Erica ciliaris. 
This plant was in splendid flower on a damp heath near the railway 
in conjunction with Ulex Galli, Erica Tetralix, Molinia cerulea, etc. 
The hybrid Erica ciliaris x Tetralix was very frequent, associated 
withthe parent species. This area has been recently encroached upon 
by arable land and is one of those which could be usefully preserved 
in perpetuity, not only as the habitat of a rare species, but as an 
example of an association which might easily come to be altogether 
destroyed. After returning to Truro the party were most hospitably 
entertained to dinner by members of the Royal Institution of Corn- 
wall, the Bishop of St. Germans presiding. A great deal of trouble 
was devoted to organising this dinner, especially by Mr. George 
Penrose, the Secretary of the Royal Institution and Curator of 
the Truro Museum. 
On August 30th the party travelled from Truro to Portsmouth 
and the peripatetic part of the expedition came to an end. During 
the week of the meeting of the British Association, however, the 
members of the party remained together, arrangements having 
been generously made by the local hospitality committee for their 
accommodation at two of the hostels belonging to the Women’s 
Training College, and here. as guests of the Mayor, they were most 
excellently entertained by Miss White the Lady Superintendent 
and Miss Fawkes the Matron, while Mr. Delahunt the Local 
Secretary of Section K, was most assiduous in his efforts to provide 
the visitors with every facility that could be desired. To all con- 
cerned in this admirable example of organised hospitality the warmest 
thanks of all the members of the party are due. 
The excursions of Section K, rather more numerous than usual, 
had been chosen with a view to the needs of the international party, 
and in addition to these one or two others were arranged apart 
from the Section. Portsmouth proved an excellent centre for 
illustrating the vegetation of the south of England, as opposed to 
that of the north and west of the British Isles, through which the 
route of the excursion mainly lay. 
On the afternoon of Friday, September Ist the party travelled 
to Chichester and drove to Kingley Vale, five miles to the north- 
west, where in a dry valley of the chalk there is probably the finest 
example of a nearly pure yew-wood in the British Isles. Some of 
the continental visitors, indeed, were of opinion that it is probably 
the finest example in Europe. Onthe top of the down above, an 
excellent example of a heath on clay-with-flints overlying the chalk, 
with Ulex nanus, a characteristic species of the heaths of the central 
part of southern England, was visited. 
Saturday, September 2nd was devoted to an excursion of 
Section K to Denny Bog and the adjacent parts of the New Forest. 
The zoned vegetation of the bog, and the adjacent woodland of oak 
and beech, proved very interesting and many good plants were 
gathered. The heathland between Beaulieu Road and Lyndhurst 
Road, on which the Scots pine, said to have been first introduced 
to the district in 1776, is rapidly spreading, was also traversed,
