PRESIDENTS ADDRESS. PLS 
the party had a day most delightful for their excursion, 
thus affording an illustration of the frequently local nature of 
falls of rain ; for on the 16th it rained heavily a few miles up 
the Tyne, whilst it was fair at Castle Eden ; and on the 17th it 
rained heavily at Castle Eden and was fair up the Tyne. It is 
unnecessary to dwell long upon the attractions of a place so well 
known for its picturesque beauty and for the number and rarity 
of the plants it produces. It is sufficient to say that all the 
scarce plants were observed by one or other of the party, more 
especially the rare and conspicuous Lady’s Slipper ( Cypripedium 
Calceolus). Four plants, bearing two flowers, of this pride of 
our Northern Flora, were seen, but as great treasures and with a 
due regard to that excellent rule of the Club, which pledges itself 
to prevent as far as possible the extirpation of rare species—they 
were left undisturbed. 
In the other departments of natural history but little was 
done, arising in a measure from the floral attractions being so 
great, and from the peculiar and beautiful scenery of the Dene 
being new to many of the party. A species of Saw Fly, which 
had not before been taken by any of the party, was caught, but 
this was the only insect taken worth notice, although the loca- 
lity, as might be expected, affords several rare species. The 
party was entirely a pic-nic one, for, from the great distance, it 
was impossible for those present to dine together as usual, without 
being too late to return home that day. 
The Third Meeting took place on Monday, July 12th, in a 
range of country extending from Haydon Bridge to Walltown 
and Haltwhistle ; a district highly interesting to the geologist 
and botanist, and also to the antiquarian, from its possessing the 
most extensive remains of the Roman Wall now in existence. 
The face of the country is very much broken by irregular hills 
of limestone and sandstone ; and at Walltown, and from thence 
towards the North, the edge of the great whin sill shews itself, 
after having been thrown up by the great Stublic Dyke. In the 
hollows are numerous hags or mosses, and here and there a small 
lake. As might be expected, many of the plants peculiar to 
such districts are found here in abundance, some of them
