REPORT OF THE CLUB'S DELEGATE. 105 that the best use of much of the land had been proved over hundreds of years, land which was arable in the middle ages was arable a hundred years ago and was still cultivated to-day Similarly the poorest land had always been woodland or heath. The greatest changes, from arable to grass, had taken place on land of intermediate quality. This had a bearing on the planning of land for the future, as any radical change from the present should be scientifically justified and the work watched by local societies throughout the country. Mr. J. L. Holland then gave an account of a survey of Northamptonshire which was a pioneer effort undertaken for purely educational purposes, special stress being laid on social study in geographical work. The concluding subject before the Conference was an account of a regional study in the Cotswolds carried out by members of the LePlay Society. Miss C. A. Simpson, who brought this forward, devoted a few introductory remarks to the aims of the LePlay Society, which may be summed up as co-operative work in regional survey by the study of Place, Work and Folk. She then showed how this kind of work had been done in and near a Cotswold valley, and how it had been made the basis of training in regional survey in all its branches. NOTES: ORIGINAL AND SELECTED.

Hen-Harrier and Scandinavian Lesser Black-Backed Gull in Essex. Mr. Norman H. Joy reports (in British Birds, January, 1936) that, on November 8, 1935, he saw a female Hen-Harrier (Circus c. cyaneus) and a Scandinavian Lesser Black-backed Gull (Larus f. fuscus), both flying near Burnham-on-Crouch. These records are noteworthy, especially the latter one, since this Gull has only twice before been identified for Essex.—Ed.
