6 THE ESSEX NATURALIST. Other ash branches were picked up beside the Hedingham Road (a distance of about 350 yards from the Grovei, and some are believed to have been carried further. An iron hurdle, standing beside this ditch, was overthrown and a wooden post- and-rail fence was broken down. Yet it is remarkable that two large hay-stacks, just put up on the very bank of the ditch, and not yet thatched, as well as a large heap of straw laid ready for thatching, were entirely untouched, though they can hardly have been as much as ten yards from the track of the storm. Mr. E. T. Adams, F.R.A.S., of Halstead, informs me that one of his carmen, who was on the road not far from this point whilst the storm was passing, described it to him as "a terrific rush of wind and smoke, carrying with it many small branches or twigs torn from the trees in the Grove. He thought at the time that it was a hay-stack on fire or an aeroplane coming down on fire. It appeared to leave a bluish vapour or smoke in its trail as it passed over the Hall Park in the direction of Heding- ham." After leaving the Grove, the storm reached the confines of the park, and, crossing a meadow and a field of potatoes (the ground here being approximately level), reached the road to Hedingham. Here it broke the top off a damson tree, damaged some currant bushes, and threw down an apple-tree, which it laid to the north-east. Yet a cottage, in the garden of which these trees stood, escaped injury (its thatched roof showing not the slightest evidence of disturbance), though standing within twenty-five feet of the apple tree mentioned. Crossing the Hedingham Road, the storm (pursuing now an almost easterly direction, and the ground here rising sharply) traversed two fallow fields and a meadow, in which it has left no trace of its passage. Its course here was more or less parallel with, but converging upon, the road to Halstead, which it reached in about a quarter of a mile, near Wells Farm. The occupants, Messrs. J. and A. Fenner, inform me that, watching the storm as it approached, it seemed to be coming directly up, and actually in, the road, which is here below the level of the fields on either side of it. It seems probable that they are quite right; for I can see no trace of any damage done in the fields here. Reaching Weils Farm, the storm turned up a portion (esti-
