"In four out of every five watches brought us to be regulated, repaired, or cleaned, we find some token. Sometimes it is a bit of ribbon or lock of hair, or a rose petal. But oftener it's a four-leaf clover. The four-leaf clover is a love-token always. It is by the maiden fair given to her lover, who tenderly stows it away in the back of his watch-case."
