borecole, or German greens. The bulb, which is green, is 
irregularly shaped, and partakes generally of the characteristics 
of No. 8. The leaves of this variety are not affected by the most 
intense frost. 
10. Early White Kohl-Rabi of Vienna (Fig. 8). — {Syn., Chou 
rave blanc tres hatif de Vienne, Fr. ; Kohl-Rabi ganz friiher 
weisser feiner Wiener, Ger.^ — This is the smallest of all the 
varieties. The bulb is perfectly globular, and of a delicate 
glaucous green ; the leaves are small, and nearly all at the top 
of the bulb ; the foot-stalks being very slender, and spreading 
where they are attached to the bulb. The flesh is white, very 
tender and succulent. They should be used for the table before 
the bulb exceeds 3i inches in diameter ; for when suffered to 
grow larger the delicate flavour and tenderness of the flesh is 
lost. This variety is the most esteemed for culinary purposes. 
11. — Early Purple Kohl-Rabi of Vienna. — {Syn., Chou rave 
violet tres hatif de Vienne, Er. ; Kohl-Rabi ganz friiher feiner 
blauer Wiener, Ger.) — This variety differs from No. 10 merely 
in the colour of the bulb, foot-stalks, and veins of the leaves. 
The flavour is said to be not so delicate, but we have found no 
difference. 
In regard to these varieties, Nos. 5 and 6 are not generally 
considered distinct from Nos. 3 and 4, the difference in the form 
of the bulb not being permanent. From the evidence we at 
present possess, we must look upon- the oblong varieties as 
sports merely of the round ; and what tends to confirm this is, 
that seed saved from both these so-called varieties produce, 
under special circumstances, round as well as oblong bulbs. 
What are the exact causes which influence the variation in the 
shape of the bulbs remain for vegetable physiologists to deter- 
mine. The purple varieties form the bulb earlier than the 
green, but both kinds arrive at maturity at the same time. 
Generally speaking, the globe varieties are best adapted for 
early crops, and the oblong, both green and purple, for the late 
or principal crops. 
The leaves of the green and purple varieties (figs. 9 and 10) 
differ somewhat in form and habit as well as colour. The 
purple kind (fig. 10) has a more upright habit, and in its out- 
line approaches the halbert shape. 
The Soil and its Preparation. 
Although the Kohl-Rabi may be raised on any good turnip soil, 
the stronger and heavier lands — even those approaching the 
condition of very stiff clays — are found most suitable for its 
growth. Where turnips will not thrive, therefore, the Kohl-Rabi
