V. — On the Composition of two Varieties of Kold-Rali and if 
Cattle- Cahhaye. By Dr. Augustus Voelcker. 
There arc two crops which deserve to be more extensively culti- 
vated than they are at present : the one is Kohl-rabi, the other 
Cattle-cabbage. Both crops have this in common, that they are 
not injured by frost, provided that the young plants are not planted 
out too early in the spring, in which case they get over-ripe 
before the winter sets in, and in a rainy and warm autumn or 
mild winter are certain to be spoiled. If Kohl-rabi or cabbages, 
therefore, are intended as winter food for cows or sheep, they 
should not be planted out too soon, nor should the whole crop be 
put out at one time. When the seed has been sown and the 
young plants set out at proper intervals of time, a regular succes- 
sion of cabbages or Kohl-rabi may be kept up as easily in the 
field as it is in a vegetable garden, and a supply of very nutritious 
and wholesome food be secured at periods of the year when other 
food is scarce. 
Kohl-rabi especially stands the frost remarkably Avell. In 
Germany, where a small variety is grown in gardens for the table, 
it is not considered good until it has stood at least a week's hard 
frost. As food for lambs it far surpasses white turnips, and is 
equal to any kind of green food with which I am acquainted. 
With proper management it may be grown so as to come in at 
the lambing season ; and even should the bulbs sprout abundantly 
and become themselves deteriorated or unfit for food, still I 
believe that sheep-breeders will not regret having reserved a 
Kohl-rabi field for the lambing season, instead of one of white 
turnips, because the tops and sprouts of Kohl-rabi, unlike those 
of the white turnip, are very nutritious. The Kohl-rabi is a 
plant which belongs, as most readers of this Journal are aware, 
to the cabbage tribe. Its leaves consequently resemble in taste, 
composition, and nutritive properties, those of the cabbage much 
more than those of the turnip, which latter are more watery and 
far less nutritious. 
I much regret that I had no opportunity last season of ob- 
taining the leaves of Kohl-rabi plants for analysis ; but as it is 
my intention to examine this season a large number of bulbs 
of Kohl-rabi, I shall at the same time direct my attention to the 
composition of the leaves. 
In the mean time the subjoined analysis of two varieties of 
Kohl-rabi may be of some interest to those who intend to grow 
this crop. The bulbs were kindly supplied to me by Mr. Innes, 
steward to Colonel North, who was a successful grower of Kohl- 
rabi last year, and has formed a decidedly favourable opinion of
