4 'sets" much if they are cut off a few times in cultivating 

 early in the season. When the first crop is gathered, the 

 land is thoroughly cultivated, and the horseradish plants 

 given good care. This plant makes its greatest growth in 

 autumn and is dug on the approach of winter or can be left 

 until spring. It must never be left two years on the same 

 land, or else great labor will be required to get rid of it, and 

 the roots will be so crooked as to be almost unsalable. 

 Horseradish is used almost entirely after grinding or grating 

 the roots and mixing with vinegar. It will keep for any 

 length of time when thus prepared and kept in air-tight pack- 

 ages. It is also ground and dried, and the young leaves are 

 sometimes used for greens. The demand is limited, though 

 considerable quantities are sold each year. Under some 

 conditions it is a paying crop, but the business is very apt to 

 be overdone. There are no varieties. 



KALE OR BORECOLE. {Brassica oleracea var. ) 



Native of Europe and Asia. — Annual or biennial. — The 



seed is like that of 

 the cabbage or 

 kohl-rabi. Under 

 this head is grouped 

 a number of vege- 

 tables closely rela- 

 ted to the cabbage 

 and kohl-rabi that 

 are used for greens. 

 Fig. 77. Kale. None of them are 



sufficiently hardy in the extreme north to stand out over win- 

 ter. They are here cultivated in the same manner as turnips. 

 In sections where the winters are mild, some of them are es- 

 teemed for planting in autumn for early spring use. 



KOHL-RABI. (Brassica oleracea var.) 



Kohl-rabi has been derived from a plant nearly allied to 

 the cabbage, and its seed resembles cabbage seed. Its pecu- 

 liarity is its swollen stem just above the ground, which is 

 used for the same purpose and grown in the same general way
