152 A DAY ON THE CROUCH RIVER. land's famous "heat and tranquillity" formula. Let us hope this valuable spat will not be killed in the winter, as was the case in 1880.2 Of fish we found Flounder (one), Plaice (common), Dab (com- mon), Sole (several), Dogfish (one, certainly a young Galeus vulgaris), Bullhead (Agonus cataphractus, several), Fatherlasher (Cottus scorpius and C. bubalis, common as usual), and several young Thornbacks (Rata clavata). The young Tope had been feeding, apparently freely, on crabs and shrimps. It was differentiated from the picked Dogfish by the fishermen through its rough coat. They showed us how to scrub the decks with the skin, and it certainly did it very well. On November 8th, I had another day's trawling at Burnham, but which, from a fisherman's point of view—my object then—was not a very satisfactory one. We took one Eel-pout (Zoarces viviparus), one of our few viviparous fish. After it had been dead some time, I took from it fifty-five young, all very lively. Four of that little purplish wriggler, the Diminutive Lump-sucker (Liparis montagui) and one Sea-Snail (Liparis vulgaris), besides the usual, but a poor, catch of "Bull-routs" (local name for the Fatherlashers, Cottus), Dabs, Flounders, and Plaice. One Bull-rout contained a Whiting as long as itself, and several contained two crabs, besides sundry shrimps and prawns. I believe they are fully as voracious as they look, and that is saying a good deal. In my previous notes I ought to have said that during the day (July 28th) we landed on Fowlness for the purpose of inspecting the Shell-bank already referred to in the Essex Naturalist (ii. 268, and iii. 39), and found that certainly the bulk of the schram consisted of Cockle-shells, but some few other species were present ; all, of course, dead and broken. This Shell-bank, probably an old Sea-beach, may be easily traced from Sales Point, Bradwell, at the mouth oi the Blackwater, to Shelford Creek, between Fowlness and New England islands. Besides these places it gives the name to many farms, as Old and New Mountsales (=the shelly mound), the How (= the hole), and to many fields. Here, on Fowlness, the sea lavender (Statice) was in the greatest abundance and just in full bloom—a lovely sight. I do not think anything further remains so be recorded of a very pleasant and by no means unprofitable day's work. 2 Unfortunately this has happened : the destruction of oyster-brood during the late severe weather has beet] enormous.
