was ripened. It also occurred at the same time in the Men- 
thorpe Ings, opposite Gunby. I have this season found a few 
isolated plants in Bubwith Ings, on the other side of the river, 
opposite the large masses in North Duffield Carrs. 
All the ‘ ings ’ and ‘ carr ’ land is annually flooded, generally 
in winter and early spring, but two years ago there were heavy 
floods after the hay had been cut, and a large part of the crop 
was ruined or floated away down stream. Mr. Hutchinson 
says that he thinks the plant was spread by these floods. He 
has watched the spread of Tanacetum vulgare L. for years in 
a like manner, and says that after heavy floods, it occurs 
sporadically in Gunby Ings. It has a permanent foothold here 
and there along the river bank. The elevation of the meadow 
land in the ings on either side of the Derwent is only about 
fifteen to twenty feet above sea level. I have not previously 
botanically worked the North Duffield Carrs, so I cannot state 
how long the plant has been there; but the data I have acquired 
this year will form an interesting basis for observations in 
future years.

BIRDS. 
Bird Notes from Marsden.—On the 22nd September 
last, a good specimen of the Gold Crested Wren was. brought 
tome. It had been picked up on the highway between Marsden 
and Slaithwaite. The bird had evidently met its death by 
flying against the telegraph wires. In October last, an im- 
mature specimen of the Kittiwake was shot at Booth Hey, 
Slaithwaite, and in November a Razorbill was shot in Wessen- 
den Valley, Marsden. Both these birds were brought to me. 
The movements of small flocks of Common and Black-headed 
Gulls from the latter end of March and throughout April 
have been interesting. The Common Gulls were always 
flying west, whilst the black-headed species, numbering twenty- 
one, were always flying east. On the 1st May I observed 
two black-headed Gulls feeding at the local Sewage Works, and 
these birds have remained ever since. They come daily to. 
the Sewage works for food, and apparently spend the rest 
of their time in the vicinity of the reservoirs in the Wessenden 
Valley, and on the moorlands by the Great Western Inn. 
When going through Drop Clough, Marsden, on the gth April, 
I noted the arrival of a flock of Chiffchaffs, numbering fully 
a score. The birds remained for some little time before 
dispersing, and were constantly in song. Lapwings have been 
abundant on the Cupwith Moors, and I also flushed a Woodcock 
in the same locality on the 3rd June.—ALFRED DEAN, Marsden.
