Nanking district they are generally sown or planted 
in October upon those lands which produce rice or 
cotton during the summer months. Frequently 
the sowing takes place before the cotton or the dry 
summer crops have been removed from the ground, 
and the young plants are seen coming up amongst 
these crops, and ready to take their place when 
they are removed. ‘This is done in order to give a 
longer season for the ripening of the different crops, 
and is very generally practised in the northern dis- 
tricts. The wheat and barley ripen in Fokien in 
April, and in the neighbourhood of Shanghae about 
the middle of May. About Chinchew and Amoy 
the wheat crops are so poor that the labourers pull 
them up by the hand, in the same manner as we 
do in our moorlands in England and Scotland. 
They are of course much better in the rich district 
of Shanghae, but the varieties of both wheat and 
barley are far inferior to ours; and as the Chinese 
sow them too thickly, they are generally much 
drawn, and the heads and corn small. The beans 
and peas seem to be exactly the same as our field 
kinds, and are certainly indigenous to the northern 
parts of China. Very large quantities of the cab- 
bage tribe are cultivated for the sake of the oil 
which is extracted from their seeds. They are 
planted out in the fields in autumn, and their seeds 
are ripe in April and May, in time to be removed 
from the land before the rice crops. It must not
