714 Crops for Pickling and Preserving. 
And again : — 
The practice of sowing onions in drills 6 inches wide is used success- 
fully. 
It will thus be seen that suitable land may be gardened for 
an indefinite time, provided sufficient manure is applied and 
proper methods are adopted. 
As representing the system of growing garden and pickling 
crops in market-gardens, the following rotation given me by 
Mr. W. Cooper, of Willow Hill, Morhanger, Beds., whose father 
is one of the most successful men in the business, may be of 
interest: — (1) Early peas, after which the land is broken up 
and seed-beds for producing cabbage-plants are sown ; (2) either 
cucumbers, kidney beans, or early potatoes ; (3) vegetable mar- 
rows, with rye or onions (for seed) as shelter. Some growers 
crop with kidney beans and early potatoes on the same land for 
years. Mr. Cooper, who is a briner as well as a grower, works 
his land on the market-garden-farming system, the following 
being an illustration of his treatment when getting ordinary 
land into fit condition for his purpose : — (1) Potatoes, manured 
with 100 bushels of soot per acre; (2) cauliflowers, manured 
with 30 tons of rotten London dung ; (3) oats manured 
with 100 bushels of soot; (4) onions manured with 40 tons 
of rotten London dung. When the land is worked round into 
condition, he prefers to take onions before cauliflowers. 
The systems of cropping hitherto mentioned do not include 
the quick succession of catch-crops ; illustrated, for example, in 
the growing of two crops at one time on the same land, which 
is not infrequent. Thus, onion seed and parsley seed are often 
mixed together and sown at one time. The onion crop is on the 
ground six months or so, and is then pulled ; the parsley is not 
injured by this, but after a hoeing, to keep down the weeds, 
grows rapidly, and is gathered through autumn a>nd winter. 
Cauliflowers, Brussels sprouts, Savoy cabbages, and other green 
crops are frequently planted among the small-topped varieties 
of early and second-early potatoes, so that when the potatoes 
are dug the land is still carrying a crop well on its way to 
maturity. Three crops are sometimes on the ground at once, 
the mixed seed being sown thus : radishes, carrots, and parsley. 
The radishes quickly become fit for pulling, and in this way make 
room for the carrots, which are pulled and bunched throughout 
summer. The ground is then left to the parsley, which, being 
of slow growth in its early stages, does not require much space 
until it has been on the land some months, though it begins to 
grow rapidly when once well established. 
Additional instances might be quoted, but this is not neces-
