, and must be blanched as required. Place a
few in frames and other protected spots. In the unused corners of sheds
and outhouses they may be safer than out of doors.

==Parsley.==--In all cold districts it is wise to secure a bed of Parsley,
in a frame or pit, or if a few plants were potted in September, they may
be wintered in any place where they can have light and air freely. It is
so important to have Parsley at command as wanted, that it may be worth
while to put a frame over a few rows as they stand in the open quarter,
rather than risk the loss of all in the event of severe weather.

==Radish.==--Sow one of the long sorts for a first supply in some warm
spot, to secure quick growth.

==Underground Onions== to be planted in rows one foot apart. They should
not be earthed up, for the young bulbs form round the stems in full
daylight.

THE ROTATION OF CROPS IN THE VEGETABLE GARDEN

This is a subject worthy the attention of those who aim at the largest
possible production and the highest possible quality of every kind of
kitchen-garden crop, for it concerns the natural relations of the plant
and the soil as to their several chemical constituents. The principle
may be illustrated by considering the demands of two of the most common
kitchen-garden crops. If we submit a Cabbage to the destructive agency
of fire, and analyse the ashes that remain, we shall find in them, in
round numbers, eight per cent. of sulphuric acid, sixteen per cent. of
phosphoric acid, four per cent. of soda, forty-eight per cent. of
potash, and fifteen per cent. of lime. It is evident that we cannot
expect to grow a Cabbage on a soil which is destitute of these
ingredients, to say nothing of others. The obnoxious odour of sulphur
emitted by decaying Cabbages might indicate, to anyone accustomed to
reflect on ordinary occurrences, that sulphur is an important
constituent of Cabbage. If we submit a Potato tuber to a similar
process, the result will be to find in the ashes fifty-nine per cent. of
potash, two per cent. of soda, six per cent. of sulphuric acid, nineteen
per cent. of phosphoric acid, and two per cent. of lime. The lesson for
the cultivator is, that to prepare a soil for Cabbage it is of the
utmost importance to employ a manure containing sulphates, phosphates,
and potash salts in considerable quantity; as for the lime, that can be
supplied separately, but the Cabbage must have it. On the other hand, to
prepare a soil fo
