THE AMERICAN GREY SQUIRREL IN THE BRITISH ISLES. 193 Euston Station; and there was a flamboyant account in the Morning Post of 24th September, 1920, of the hunting of one in Earl's Court Road. In the western district they made their appearance at a later date, being first observed in the central parks about fifteen years ago (say 1908), but they did not become noticeable till about 1914. The controlling authority, H.M. Office of Works, have kindly given me a report for the Royal Parks and I have included their information in these notes. (See also Appendix B.) From this it appears that at present the estimated number in the central parks is only about twenty, and the Department having extended their patronage and approval to the efforts to establish bird sanctuaries in the Royal Parks have determined to keep down the numbers of the squirrels. Here are their words from the published Report of their special Committee:— "Another and serious danger to bird life arises from the "presence of grey squirrels in large numbers in the Central Parks.

None of the other London Parks seems to harbour this squirrel although casual occurrences have been reported; for instance, Mr. W. S. de Lisle has seen it in Clissold Park. Home Counties. Essex.—Coming to the Home Counties the genius loci re- quires that Essex be mentioned first, even although it is the only one of the five in which the grey squirrel has not secured a footing. I have only one definite record, kindly given me by Miss G. Lister, from Mr. George Mitchell, whose work takes him frequently through the Epping district. He knows the grey squirrel well in its native North America and saw one in the upper part of Epping Forest near Gaynes Park during the summer of 1921, but has not seen it anywhere since. Miss Johnson tells me that some years ago grey squirrels frequented 7. Bird Sanctuaries in Royal Parks, p. 5, H.M. Stationery Office, 1922.
