We had observed long processions of wheelbarrow men moving from the canals through the streets carrying large loads of the green tips of rape in bundles a foot long and five inches in diameter.

During this time not a man in the train halted or slackened his pace.

This rape is very extensively grown in the fields, the tips of the stems cut when tender and eaten, after being boiled or steamed, after the manner of cabbage. Very large quantities are also packed with salt in the proportion of about twenty pounds of salt to one hundred pounds of the rape. This, Fig. 68, and many other vegetables are sold thus pickled and used as relishes with rice, which invariably is cooked and served without salt or other seasoning.

It is known among the foreigners as Chinese “clover.” The stems are also cooked and then dried for use when the crop is out of season. When picked very young, wealthy Chinese
