field meetings for 19h 357 



Haswell, Easington and Deneholme, Friday, 

 July i ith, 191 i. 

 The fourth meeting of the season was held in South-East 

 Durham under the genial guidance of Mr. Edward Potts. 

 Detraining at Haswell the party proceeded by a lane leading 

 by Easington, to Haswell Moor, which, to the disappointment 

 of all, was found to have been recently drained and brought 

 under cultivation ; so that now fertile fields lie where once the 

 Primula farinosa and several other interesting marsh plants 

 were wont to grow. At Thorpe the higher reaches of Horden 

 Dene provided a picturesque walk for some distance seawards, 

 when the party followed the sea banks to Blackhall Rocks, 

 where a hearty tea at the inn was enjoyed. Several plants 

 were observed in flower, including the dwarf mallow, the 

 twayblade, the sweet-scented orchis and the Geranium 

 sanguineum, its exceedingly handsome crimson flowers con- 

 trasting beautifully with an equally profuse display of the 

 golden rock-rose. 



After tea an hour was spent investigating the Blackhall 

 Rocks ; a huge example, of the maritime woodlouse, Ligia 

 oceanica, and colonies of the rockpool springtail, Anurida 

 maritima, being observed. 



Personally I was only able to join the party in the afternoon, 

 and was therefore unable to carry out much collecting. Several 

 thrips, mostly common, were taken from corn, rest harrow and 

 marjoram ; a rare and little-known woodlouse, Trichoniscoides 

 albidus B.-L. was found on the sea-banks, and several 

 myriapods, listed below, were seen between Horden and 

 Blackhall Rocks.
