PRESIDENT’S ADDRESS. 321 
Roman station of Vindolana, the party crossed the country to the 
old military road, in the vicinity of which are the little moorland 
lakes, or loughs, as they are provincially called, that were to form 
the boundary of the day’s excursion. These Loughs, situated in 
a wild district unadorned with wood, possess little picturesque, 
beauty, with the exception of Crag Lough, a small sheet of water 
lying beneath fine basaltic cliffs, formed by the whin-sill, which 
here rises into a range of hills crossing the country in a direction 
nearly east and west, and presenting a bold escarpment to the 
north. These hills give a striking character to the surrounding 
scene, and are well known to the antiquary from the circum- 
stance of the celebrated Roman wall passing along their summits. 
A few of the members explored the northern shore of Crag Lough, 
where Mr. Storey gathered Polamogeton rufescens, P. perfoliatus 
and P. pectinatus: the remainder pursued the line of the Roman 
wall over the top of the crags, descending to the lake at the east 
end, where some of the more assiduous naturalists commenced 
turning over the loose stones at the water’s edge. This search 
was rewarded by the discovery of two beautiful fresh-water 
zoophytes, new to the north of England, which, as before recorded, 
were obtained by Mr. Albany Hancock. A few freshwater shells 
were observed, among which were Physa fontinalis, Planorbis 
albus, and Ancylus lacustris ; these were all of small size, ap- 
parently dwarfed by their exposure in this elevated situation, 
A searce little bivalve, Pisidium nitidum, was.also found. Brom- 
ley Lough was only reached by two of the botanists, Mr. Storey, 
and Mr. Daniel Oliver, intent upon obtaining ‘the glory of this 
barren waste’, the beautiful white water lily, Vymphca alba, which 
here grows truly wild. Scutellaria galericulata was likewise 
found, growing upon the margin of this lake. 
Again following the line of the Roman wall, whose preservation 
in so perfect a state called forth the admiration of those gentlemen 
who had not previously seen it in this locality, the party passed 
along the cliffs as far as the great Roman station of Housesteads, 
the ancient Borcovicus, where some time was spent in examining 
the extensive remains. From hence the party, well pleased with 
the events of the day, made the best of their way to Haydon
