Another method, cheaper and quite as satisfactory, especially on farms or in market gardens, is to trench the celery in the open field. The situation of the trench must be a dry one, where there will be no standing water. The trench must be nearly or quite as deep as the height of the celery, with perpendicular sides, and a foot or less in width. The stalks are set upright in the trench, with all decayed or worthless leaves removed, as closely as they will stand, without soil between them. To keep them in that condition is purely a matter of care. If they are buried deeply and the weather proves warm they will rot. But if the covering be decreased in warm weather and increased in cold weather, the celery can be kept in perfect condition. In private gardens celery is often planted in double rows, a foot apart, and wintered where it grows by covering deeply with soil. An excellent plan is to make an A-shaped trough of two boards to turn the rain, on top of which a greater or less amount of straw, leaves or litter may be piled, if needed. Mice sometimes do considerable damage to stored celery, but are more easily controlled in short trenches than in long ones. Small amounts of celery may be stored in cellars, in boxes a foot wide and a foot deep, with damp sand in the bottom. No soil is needed between the plants. The coolest and darkest part of the cellar is best for storage. =Diseases.=--Celery diseases are preventable and insect attacks are few. For blight, kainit is recommended, both in the seed-bed and open field. For rust, the Bordeaux mixture is advised. Hollow-stemmed or pithy celery is the result of poor stock or improper soil, and can be avoided by the use of more manure and more water. =New Process.=--The method of growing celery in highly enriched soil, with plants set 6 or 8 inches apart both ways, is quite feasible. The plants stand so close as to blanch each other to some extent, but the system has never attracted general favor. A great deal of water is required. Cultivation is possible only when the plants are small. =Profits.=--The use of celery is obviously on the increase, but the demand is for a first-class article. The cash results may be set at anywhere from $200 to $500 per acre. The actual net profits of well-conducted operations are considerable. WATER CRESS. Water cress, a vegetable closely allied to several other edible cresses, is used in very large quantities in all city restaurants. It is a much-esteemed winter relish, and is mostly served with every one of the thousands of beefsteak orders daily filled in the great eating houses and lunch rooms. The demand for it seems to be on the increase. [Illustration: Water Cress.] Water cress is of the easiest culture. It can be grown in the soil of a forcing house under glass, and is extensively produced in this way by market gardeners.
