44 THE ESSEX NATURALIST. road-sweepings, has quite suddenly produced startling results. Here have sprung up the Blue Pimpernel (which has apparently walked four miles across country from Cressing), together with Wild Mignonette (Reseda lutea), a piece or two of Dwarf Mallow, Sun Spurge, White Heartsease, and a riot of Annual Mercury, Many-seeded and Upright Goose-feet and Dyer's Rocket. This last and the Teasel are always plentiful in Bocking from the esteem in which they were held by the bay-trade. In St. Peter's Road a single clump of Melilot has dug itself in on the trench cut last year for an electric cable. I think it has tramped from Felsted, four miles away. In August I found a milfoil in colour as red as the reddest knapweed, with mottlings deeper still. He was on a sandy southern bank and perhaps the drought had turned his head. But this cannot apply to a Cow-mumble of similar hue which I found against Pattens Wood, Blackmore End, for she was sheltered from the sun and in a damp locality. In the next parish to Bocking Miss Vaughan has in her garden at Rayne (self-sown) a tall species of London Rocket which she regarded as Sisymbrium Clio, but which Miss Campbell now identifies as S. Altissimum. In the same garden (raised from wild seed) are those two lovely little Crane's-bills, striatum and phaeum; the former is white with delicate mauve veins, giving the effect of an old-fashioned printed cambric, the latter the rich deep tint of vintage port. A visit to Tiptree Heath during a prolonged air-raid at the end of August produced food for reflection, with the flower of a heathen race so furiously raging together overhead, and the flowers of God's field smiling up at him from below. Here was a riot of Copse Buck-wheat, Sneezewort, Stinking Chamomile, and Greater Bird's-foot Trefoil all tangled up together in rich profusion; hard by were flowering rushes and cottony bushes of Sallow, the nomenclature of which is beyond my feeble knowledge. Mention of Bird's-foot reminds one that our simple-minded forefathers had wonderful powers of observation which led them to the study of nature and to apt nomenclature. From the feathered tribe they named Crowfoot, Cuckoo-pint, Wake-robin, Dove's nest or Columbine, Bird's-eye, Hawk's-beard, Larkspur,
