124 RATS AND MICE IN ESSEX. and unlamented; let us hope this plague may stay the hand of the destroyer on some few estates in the county, if only out of consider- ation for the tenants' produce. Doubtless the great immediate cause of this unwonted injury from these two destructive and prolific rodents—always acknowledged as the farmers' enemies—was the wet harvest and the mild winter. In Essex we had heavy rains from the end of July through August, culminating in the great storm and tempest of September 2nd and 3rd. This drove most of the rats and mice more especially into the traves and sheaves of corn, which were perforce left out in the fields for a much longer period than is usual; these were used as the rodents' homes and were carted home with their inhabitants. The corn being in bad condition it was impossible to thresh it for some time and the mice increased and multiplied throughout an unusually mild winter. Some corroboration of this being the true explanation is found in the fact that I have known stacks on frames (supposed to be vermin-proof) to be as badly affected as any; doubtless the mice were stacked with the corn. Let us hope this unwelcome rodent plague is stayed, but it is nevertheless the duty of our members to assist in writing its true history. Richard Jefferies' "After London" (see pp. 9-12), is not yet. An Albino Mistle-thrush.—Last week a lad brought me a bird which he had killed with a stone, it turned out to be a white Mistle-thrush, about a month old ; there are a few very faint markings on some of the breast-feathers, but in other respects it is pure white. The specimen is in the hands of Messrs. Cooke and Co., Museum Street, for preservation.—R. N. Arnold Wallinger, Writtle, Chelmsford, May 20th, 1890. Golden Eagle laying at Woodham Walter.—I have just had the pleasure of blowing two eggs of the Golden Eagle, In markings, one very much resembles the specimens figured in Butler's "British Bird's Eggs" (pl. i., fig. 1), but both are more elongate ; the other is more streakily blotched with lilac-brown. These were laid by Mr. Garratt's bird in March last, one on Thursday the 13th, the other on the following Saturday. Mr. Thomas Garratt, of Bishop Stortford, had the eagle when young, and kept her for seventeen years; upon his death, three years ago, it was brought by his brother, Mr. Samuel Garratt, to Hoe Mills, Woodham Walter, so it is now twenty-one years old. Last year, for the first time, it laid an egg which was found broken in its aviary. This year the eggs were removed, and two duck's eggs substituted in a nest ; there she sat well on for a week, when they were disturbed and broken, apparently by accident. The eagle herself is a fine bird, and Mr. Garratt is endeavouring to procure her a mate.—Edward A. Fitch, Maldon.
