was drier once, before it had become covered with bog-mosses. 

 The most tempting place for lunch was a boundary stone and 

 a broken-down wire fence, there was plenty of water in one's 

 (boots, but none to drink, but the sandwiches were good. 



After traversing other parts of the bog, including a large 

 area where Ling was entirely absent, a return was made to the 

 Balder valley-slopes, and after a few more observations over a 

 few miles of rough wet walking, we sought our conveyances, 

 satisfied with the day's work which had added the Sphagnum 

 Bog as a plant association new to all. 



FIELD NOTES. 



BIRDS. 



Cuckoo's Egg in Sedge Warbler's Nest. — Whilst with 

 Rev. Mr. Woods near Driftield, I came across a Sedge Warbler's 

 nest containing four eggs, one of which was a Cuckoo's, and 

 was practically fresh. It seems late to find these eggs in July. — 

 H. G. \\'illia:\is, Bainton, Driffield.

 MOSSES. 

 Plagiothecium silesiacum B. & S. in the East Riding. — 



At the meeting of the York and District Field Naturalists' 

 Society at Fimber on Saturday, the qth July, I found the above 

 moss in fruit. It is extremely rare and of great interest to 

 bryologists. Its name in Braithwaite's ' British Moss Flora ' 

 is Isopterygimn repens.. The last time it was found in the British 

 Isles was in 1847, when Dr. Spruce discovered it in Arncliffe 

 Wood, near Goathland. The previous and first record was by 

 Mitten in Kent, in 1843. At the present time the moss is 

 known only in Yorkshire and Kent. The Fimber Station adds 

 the moss to the East Riding flora. Its habitat is a curious one, 

 on rotten wood, and pine needles. — Wm. Ingham, York, nth 

 July, 1910.
