If fruit trees be planted, vegetables may be grown in rows. As soon as the early vegetables mature they are removed, and a midsummer crop planted. These are followed by a fall or winter crop. Radishes, lettuce, and cabbage grow at the same time and on the area formerly used for one crop. Early potatoes and early cauliflower are followed by Brussels sprouts and celery, two crops being as easily grown as one by intelligent handling. The best beans are grown among fruit trees. The principles of "double-cropping" are summarized by Professor Thomas Shaw, in _The Market Garden._ "Onion sets may be planted early in the season and onion seeds may then be sown. Between the rows cauliflower may be planted. Later between the cauliflower, two or three cucumber seeds may be dropped. The onion sets up around the cauliflower may be taken out first, and the cauliflowers in turn may be removed in time to let the cucumbers develop. "Midway between the rows of onions grown from seeds, we can plant radishes, lettuce, peppergrass, spinach, or some other early relish, which will have ample time to grow and to be consumed before harm can come to the onions from the shade of any one of these crops. When the onions are well grown, turnips can be sown midway between their rows." So we get two crops of onions, besides cauliflowers, cucumbers, and turnips off the same place. Weeds won't have much chance in soil treated like that. "Multum in Parvo Gardening" (Samuel Wood) claims L 620 ($3100) from one acre by the expenditure of considerable capital in growing fruit against brick walls--it cost over $3100 to prepare the land, of which the walls cost $2300. In this system the fruit trees are pruned and trained till they look like firemen's ladders. "In the suburbs of Paris, even without such costly things with only thirty-six yards of frames for seedlings, vegetables are grown in the open air to the value of L 200 per acre." ("Fields, Factories and Workshops," page 80.) "At the present time, for fully 100 miles along the Rhone, and in the lateral valleys of the Ardeche and the Drome, the country is an admirable orchard, from which millions worth of fruit is exported, and the land attains the selling price of from L 325 ($1625) to L 400 ($2000) the acre. Small plots of land are continually reclaimed for culture upon every crag." (Same, page 133.) In California we hear (from George P. Keeney) that while good truck and fruit lands usually sell for $25 to $350 per acre, the land with full-bearing fruit or nut trees often sells at $1000, and even up to $2000 per acre. There is no reason why any intelligent persons should not make their land increase in the same way. The London Daily News reports that in one year, which was not a good season for all crops, on a half acre of land, Mr. Henry Vincent, of Brighton, England, raised the following products:
