FIELD NOTES. 
BIRDS. 
Sanderling in Craven.—On August 14th, 1909, a female 
Sanderling was shot at Tosside-in-Craven, by C. P. Charles- 
worth, of Skipton. It is unusual for this species to be so far 
inland.—W. Wilson, Skipton-in-Craven. 
Weights of Birds.—During the seasons of 1908 and 1909 
I weighed a few birds which passed through my hands, and 
which may be interesting to record. The birds were all dead 
at the time of being weighed, with the exception of the Little 
Owl, which was placed on the scales alive :—Gold Crest, 74 
grains; Blue Tit, 186 grains; Twite, 250 grains; Nuthatch, 
(in poor condition) 320 grains ; Short-eared Owl, 1 lb. ; Great 
Crested Grebe, 24 lbs. ; Peregrine Falcon, 2 lbs. 6 ozs. ; Little 
Owl, 8 ozs.—W. WILson, Skipton-in-Craven.

FISHES. 
Destruction of Fresh-water Fish in the Wharfe.— 
Evidently through some abominable carelessness at the 
gas works in allowing chemical refuse to escape into the river, 
enormous numbers of fish (over 3000 dead, have been taken 
out) have been destroyed below Ilkley. The majority of these 
were trout, though two barbel weighing each 8} lbs., a large size 
for this portion of the Wharfe, were found. Practically all the 
trout were under a pound in weight.—R. FortTuNE, Harrogate.

ARACHNIDA. 
British Velvet Mites.—The actual specimens of mites des- 
cribed by Dr. C. F. George, of Kirton Lindsey, in a series of 
articles to this journal, have been presented by him to the Hull 
Municipal Museum, where they will be available to students 
of this branch of Arachnology. The following is a list of the
