Onion threads.—These are a finest example of garnish to salads of all kinds, more delicate even than chives. They are simply the young stalks thrown up by the seeds when planted eight or ten days. Onion and celery seed are both invaluable if lightly planted in shallow boxes and kept well watered in a warm corner of the scullery, or some place of the kind, as they are then always at hand for flavouring.
