268 THE ESSEX NATURALIST. is not the place for a technical description of boats' sails and rigging but a knowledge of the elementary differences between the various types of boats gives the same gain in intelligent interest to a waterside ramble that a slight knowledge of botany adds to a walk in the country. Therefore, let a "Stumpy" be distinguished from her taller sister by the absence of topmast and topsail, and a river Barge from a sea-going Barge by her usually taller mast and absence of bowsprit. All barges, being flat-bottomed, have leeboards, which are lowered when sailing to prevent the boats being blown sideways across the water like pieces of paper on a pond and in this respect are similar to the Dutch Schuyts, Botters and most other Dutch sailing vessels. Nevertheless, they have no direct ancestry in Holland and are, in fact, the last descendants of a long line of English cargo boats. At one time, the Hay Barge was a familiar sight on the rivers of Essex, loading her bulky stack at some remote farm quay in an Essex creek and sailing on a two or three days' journey to London. Now, this traffic is carried almost entirely by road and I have seen but few hay-barges in the last ten years. Timber is a frequent barge cargo in these days of much building and so are bricks, while cement barges are more often seen in Kentish waters than north of the Thames. Cement barges often carry sails prominently decorated with the trade mark of their owners. Formerly, all sorts of trades used barge sails to carry their advertisements but now one seldom sees any marks but those of cement companies. Corn is never carried by water for short distances now that the motor-lorry can reach almost every farm, but before the war many Essex barges were engaged in this trade. For both cement and corn, a thoroughly seaworthy and watertight hull is essential, for if once a barge is strained or "wrung," as it is called, by laying her on an uneven bed or across a small runnel, she may become leaky and useless for these special cargoes, easily spoiled by water. For some years, I owned an Essex corn barge which had been used by the Admiralty during the war for carrying explosives; after at least forty years' hard work she was as sound when converted to a barge-yacht as when she was built. "Rainbow" (that is her name) was one of the smallest of this class of boat,
