The vine of the cucumber must be kept in vigorous growth, not only by cultivation and a sufficient water-supply, but by care in removing all the fruit as soon as formed, for, if the seeds be permitted to mature, the vine will quickly perish. It is the purpose of the vine's existence to produce ripe seeds, and it will make repeated and long-continued efforts to accomplish this end. In gathering the cucumbers, it is important to avoid injuring the vine. Some growers use a knife; others break the stem by a dexterous twist, without injuring the vine in the least. [Illustration: Johnson & Stokes' Perfected Jersey Pickle Cucumber.] It requires 300 cucumbers (more or less) of fair pickling size to make a bushel, and it is estimated that an acre will produce from 100 to 200 bushels, or even more. When the pickles are pulled while quite small, the number runs up to 125,000 per acre; and the pickle factories in some cases make their estimates on a yield of 75,000 per acre. The price is variable, but often quite profitable. CUCUMBER.--For planting in the South to ship to Northern markets use Improved Arlington White Spine. Giant of Pera is a fine table sort. For pickling, plant Johnson & Stokes' Perfected Jersey Pickle. For description see our "Garden and Farm Manual." =Downy Mildew.=--A disease which lately threatened to destroy the business of growing pickles in New Jersey and elsewhere, the downy mildew of the cucumber, can be fully overcome by spraying the vines with Bordeaux mixture. It requires six or seven applications, at intervals of a week or ten days, to conquer this comparatively new disease. Downy mildew is a fungous trouble affecting the leaves and destroying the further usefulness of the vine. A recent New York experiment showed a yield of $173 worth of pickles per acre under spraying as against complete failure where the Bordeaux mixture was not used. The cost of spraying was $9.50 per acre, leaving $163.50 per acre as the value of the crop saved by the operation. EGG PLANT. The advisability of growing egg plants in farm gardening operations is a question of location. On a suitable soil, near a good market, the operation will be a profitable one, if rightly managed. The egg plant is a tender vegetable, botanically allied to both the tomato and the potato, but less hardy than either, especially when young. For this reason it is best to delay sowing the seed, even in hot-beds, until cold weather is past, for the tender seedlings never fully recover from a chill or set-back. Indeed, for the farm gardener the month of May is early enough to sow the seed under glass, for this plant grows with great rapidity in a warm soil, and May-sown seed not infrequently yields plants that outstrip those sown a full month earlier.
