It is still customary with our boys, in most parts of England, to go out and gather slips with the willow flowers or blossoms at this time: these are selected as representatives of the palm, because they are generally the only plants at this season, easily to be come at, in which the power of vegetation can be discovered.
In the neighbourhood of London, too, "palming" is still a practice on the Sunday before Easter. The weavers of Spitalfields, leaving their murky workshops, customarily ramble into the fields and lowlands of Essex, on this day. to gather "palm," and inhale a better atmosphere. Our artist has depicted a scene of the return of one of these parties. The yellow catkins, or male-flowers, are more highly prized than the white, or female flowers.
