The following brief remarks on market-gardening will, I trust, prove instructive to some of the readers of ' The Gardener,' more especially those who may not have had an opportunity of personally observing the way in which the markets of our great and fast extending metropolis are supplied with vegetables. The greater proportion of the vegetables used in the city or east end of London are grown in Essex, which is fast becoming a complete vegetable garden.

A more generally unfortunate season has seldom, if ever, been experienced, and upon no one does this fall more severely than those who follow agricultural and horticultural pursuits. Although in this immediate vicinity there are few of what are termed market-gardeners, yet nearly or quite all the farmers grow large quantities of the more common kinds of vegetables for London, more especially for the Spitalfields and Borough markets. These vegetable crops are the most expensive, but if the crops, and the prices realised, are good, they are very remunerative, and also prove excellent preparations for the ordinary farm crops. Peas, Runner Beans, and Potatoes are the most extensively grown, but many grow a few acres of Turnips, Carrots, Beet, and Onions, etc. Peas, in particular, are the most generally grown, but have not paid over well lately. This is partly attributed, strange to say, to the slackness of trade in the north, as well as in London, as in prosperous times many truckloads of bags and sieves of Peas are bought up in the London markets and despatched northwards, better prices being the natural consequence. Early Peas are mostly grown, as they generally pay best, and the land being cleared early, gives the opportunity of sowing Turnips, planting Cabbage, Broccoli, etc.

Sangster's No. 1 is most commonly sown, but Caractacus will eventually supersede it. Some of the more enterprising have sown William I., and are well pleased with it. For later supplies, Laxton's Supreme, Blue Scimitar, Yorkshire Hero, etc, are sown. The latter is a particularly good variety, being to the farmer what Veitch's Perfection is to the private gardener, and is one of the most, if not the most, useful Pea in cultivation. Peas are sown on heavily manured land in drills about 2 feet 6 inches apart, and of course no stakes are used. The growth is very sturdy, seldom exceeding 2 feet in length, and the produce is generally heavy, and the pod well filled. Next in importance to Peas are Runner Beans: these, too, are sown on land well manured, and in lines about the same distance apart as Peas. They are thinned out to about 18 inches apart; they are not allowed to run, but are kept closely pinched back; and the bloom, thrown well above the foliage, presents a very pretty sight, extending, in some instances, over an unbroken field 15 or more acres in extent. Treated in this way, they are picked from much earlier than in private gardens. This season they commenced picking the first week in August - nearly a month later than last year.

The growers experienced very great difficulty in getting a good plant, - the seed rotting in the ground in the first instance, and slugs destroying those that did vegetate. It has.also been very difficult to keep them clear of weeds. The large podded varieties are mostly grown, but some of the salesmen, who are also growers, have found the small podded varieties the most profitable, as they fetch better prices, and oftentimes selling when the coarser ones will not, and being smaller, are produced in greater profusion. The farmers, as a rule, sell their crops of Peas and Beans early in the season as they stand, either to the market salesmen or other speculative persons, who in their turn employ gangs consisting of men, women, and children, many of whom come out of towns "for the season" (one buyer I am acquainted with this season employed 120 pickers), who either work by the day or by measure. Sieves and bags are provided by the salesmen, the charge for which is included in their commission. The best prices for Peas in this district was 12 per acre, and for Runner Beans 15 per acre.

The latter is a long price as the season will be short, as, of course, the first severe frost destroys them, and we have already (4th Sept.) had some frosty nights.

Potatoes is another expensive crop, and will, I am afraid, pay very badly, disease being very prevalent, which has caused many to lift and sell early at a rather low figure. Those who fortunately have a good crop of late Potatoes will get good prices for them, but this will fall to the lot of but few. Early Dons, Early Rose, and Shaws are grown for the early supply, these being followed with Victoria and other Regents. Rocks, and Scotch Champion Red Skin, Flourhall, would not sell well last season, but many regret not having planted any this season, as such vigorous varieties only appear capable of withstanding the disease. Sutton's Magnum Bonum will eventually become a popular variety, as with us it is the only variety that has withstood the disease, and this will have the effect of bringing it into prominence. Last winter Turnips of any description realised high prices, as also did Carrots, Leeks, and Onions, being in great demand for soup making (which is more extensively made during cold weather), but as soon as the weather became mild, it did not pay to send them up. Onions are an expensive crop, on account of the cost of seed, the amount of manure, and the hand-work requisite to secure a heavy crop.

They kept badly last winter, and probably will be still worse to keep this season, as they are very backward. Where nitrate of soda was used as a manure they are still remarkably green. I have my doubts about their keeping, and shall make inquiries on the subject. Onions are oftentimes sown broadcast, and stand thickly on the ground. During the past winter "green stuff" of every description realised extraordinary high prices, this included much that was really sown for sheep-feed, such as Rape, Turnip-tops, etc. Small Cabbages were sold in the market at one penny a piece, the consumers having to pay threepence for them; and other species of the Bras-sica tribe realised proportionate high prices. Much that sold readily would not during some seasons pay for the carriage up, and I very much doubt if so great a quantity of stalks and leaves were ever eaten in London before.
