RATS AND MICE IN ESSEX. 123 It is quite easy to believe that the stack seemed positively alive with mice, as was asserted. Rats have been commonly reported as coming and going quite mysteriously, appearing in large numbers on a certain homestead all at once, and in other cases disappearing as suddenly—the same occurring in the hedgerows and fields. Much damage to pea and bean plants when sown in the spring was complained of, owing to the rats removing the seed. Mr. Taber had a large field of kale which, in the winter, was suddenly attacked by rats, eating out the pith ; they quite spoiled part of the field, and then as suddenly dis- appeared, to be found, however, in a neighbouring stack of Mr. Wake- lin's, where between 200 and 300 were killed. The rat being a murivorous animal, it is not often that any numbers of rats and mice together are found in the same stack ; the smaller mouse is the more destructive species, as it spoils so much more than it requires for its own maintenance,—not so the rat. Even our bargemen have been troubled with the rat plague, and they have a wholesome dread of getting this animal on board. If such is suspected a supply of fresh water is at once provided for them, as it is only through two two-inch planks to the water outside, and a rat is sure to find the way through this thin partition if long imprisoned. Lately a valuable cargo of guano was spoiled and a Maldon barge nearly sunk, owing to the existence of a rats' hole in the vessel. One barge-captain related how the rats at certain wharves would come on board, and in one instance he had to arm himself with the mop and knock them off into the water as they came along the warp one after the other. Other members may be able to give further details and add to this account of the plague of rats and mice in Essex. I must, however, say a word or two as to its cause. I have heard four different causes suggested, in all of which there is probably some truth. Locally, for preference, certainly comes the Rabies (muzzling of dogs) Order of 1889 of the Board of Agricul- ture ; then the number of derelict or uncultivated farms in the county which have been supposed to provide happy breeding-grounds. Advertisements for stoats and weasels for export to Australia and New Zealand have appeared in our newspapers, and with these worth five shillings each, it is quite possible that the natural enemies of rats and mice have been unduly interfered with. The almost complete extermination of kestrels and owls has gone on unchecked
