Onions may be raised successfully either from seed or from sets. If to be grown from seed no time should be lost in getting it sown in the spring. Sow in drills and thin the plants when about the size of quills, disturbing the remaining plants as little as possible. For southern latitudes and for an early supply it is better to grow onions from sets planted three inches apart, in drills. Sets are small onions grown the previous year, from seed sown quite thickly. Sets may be planted very early, as they will not be injured even if the ground should freeze after they are planted. _Wethersfield_ and _Danvers_ are good varieties. For extra large specimens, select _Italian varieties_. KOHL RABI, EARLY CABBAGE AND CAULIFLOWER. Seed of kohl rabi, early cabbage and cauliflower should be sown in a hotbed, and the plants transplanted to the open ground when four inches high. Kohl rabi is grown for its turnip-shaped bulb, which is formed above ground, by the expansion of the stem. The bulb should be used while young and tender, as age detracts from its good quality. Set the plants eight inches apart in the row. For later use sow seed in drills and thin to the proper distance apart. When well grown and properly prepared for the table, the kohl rabi is one of the most desirable of vegetables, and should be in every garden. _Early White Vienna_ is the best variety. Plant early cabbage in rows, with plants eighteen inches apart in the row. After trying several different sorts I have decided upon _Early Jersey Wakefield_, _Early Flat Dutch_, and _Fottler’s Brunswick_, as the best varieties for this latitude, and, as the cabbage worm has made late cabbage an uncertain crop for several years past here, in southern Illinois, we have planted largely of the Early Flat Dutch cabbage and had it picked and put up before the cabbage worm made its appearance. This I know, from experience, to be better than the use of all the insect powders combined.[20] To grow cauliflower to perfection, the ground needs extra heavy manuring, and the plants must be supplied with an abundance of water as soon as heads begin to form. Plants should stand the same distance apart as early cabbage. The outside leaves should be pinned together over the centre, to shield the head from the direct rays of the sun, which often cause it to turn green, thus rendering it inferior in quality or entirely unfit for use. _Early Snowball_ and _Erfurt_ are both good and reliable. Nowhere does success depend more on the quality of the seed than in the cauliflower. SWEET CORN.
