ating probably for all time the vegetation of the preceding one. 
Again; the variety of the ballast matter, consisting as it does of 
granite, chalk or flint, sandstone, the refuse of slate quarries, clay, 
alluvium of divers kinds, etc., must be taken into consideration ; 
and more important still may be the variation of climate of our 
northern latitudes from that of the lands from which the several 
substances were originally procured. It is quite reasonable to 
assume that but for the notice taken of them by my co-workers 
and myself, all record of their existence upon our coast-line would 
quickly have perished. 
The case is somewhat different at Silloth. There the dressings 
from Messrs. Carr’s large corn mills, consisting of what a native 
Cumbrian would designate as ‘‘popple,” are either gratuitously 
distributed or sold at a nominal figure to the mill-workers and 
other labourers for poultry-keeping purposes. Scattered about the 
banks contiguous to the dwellings, the waste corn is quickly picked 
up by the fowls, and the residue, consisting of the smaller seeds, 
by and bye germinates, and the hillocks are quickly clad with vege- 
tation of home, or more commonly of foreign origin. The few 
opportunities that occur to me of visiting this station, never fail to 
result in the discovery of some plants not previously noted. 
I have gathered at Silloth the following different species classed 
as indigenous to some portion or other of the United Kingdom. 
This is probably the stage at which I may most appropriately 
refer to the recent alterations that have been made in the arrange- 
ment of plants in the 8th or latest edition of the London Catalogue, 
as compared with preceding issues. The former editions contained 
at the end an appendix, which embraced a large number of species 
considered as aliens, casuals, waifs of cultivation, etc. The great 
majority of these have been re-introduced by Mr. Fred J. Han- 
bury and his editorial co-workers. The change can hardly be 
classed as a popular one, and I fear that it may be productive of 
confusion in quarters where the science of Botany is but imperfectly 
understood. As, however, the members of the British Association 
have accepted the new order of things, I have followed their 
example. Many such stragglers have been found at Silloth,
