The "scuttle-mouths," as they are termed from their huge shell, pay no attention to season, and consequently oyster-day has now in a great degree lost its significance. The 4th of August is still, it is true, the opening day at Billingsgate, but the supply from without has taken the wind out of its sails. Only those who have witnessed the crowds filling all the streets leading to the market long before the hour of business--six o'clock in the morning--can understand the eagerness exhibited of old to obtain some of the first day's oysters. All this is now gone. There were not more than eighteen smacks at the opening of the present year, and, few as were the arrivals, the buyers were not eager. The Mid-Channel oysters, which have thus disturbed the old trade, are of a large and by no means delicate kind, such as come from Tenby, Jersey, &c.--coarse fish, eaten by rough men--third-class oysters, in fact, which rarely penetrate to the West End, unless to make sauce. Real natives are greater aristocrats among their fellows than ever; the demand for them has for a long time far exceeded the supply, and the price has consequently risen. Of the birth, parentage and nurture of this delicate fish, a curious tale could be told. Designed for fastidious palates, much care and attention is bestowed upon its breeding. The _habitué_ of the Opera, who strolls up the brilliantly lighted Haymarket towards midnight, and turns into any one of the fish supper-rooms that line its western side, little dreams of the organization at work to enable him to enjoy his native. Most of the oysters, with the exception of the Mid-Channel bed, are regularly cultivated by different companies, who rear and tend them at different parts of the south coast, and of the Thames at its mouth. Of these companies there are nine, in addition to individuals who possess and work what might be called sea-farms, several of which are miles in extent. In all the beds there is a certain space dedicated to natives. At Burnham, Essex, the "spat," or fecundated sperm, is stored in large pits, and sold as native brood, which is afterwards "laid" in that portion of the different beds appropriated to privileged oysters. Here the young natives remain for three years, when they are generally brought to market. So far their education is left, in a certain degree, to nature; but once in the possession of the fish-shopkeepers, art steps in to perfect their condition. They are now stored in large shallow vats, being carefully laid with their proper sides uppermost, and supplied daily with oatmeal: a process which is calculated rather to fatten than to flavour, and there are many who think that, like show cattle, they are none the better for over-feeding. "Natives," packed in barrels, form one of the articles of food that is largely sent out of London into the country, as all persons know who travel much at Christmas time, and notice with astonishment the pyramids of oyster-barrels which
