It is fortunate that the milfoil is attributed with so many virtues and has the sanction of the great Achilles, whose name it bears, and who is said to have discovered its healing properties, and to have employed them for the benefit of his soldiers; for certainly it is not pretty. That is, we think it is not pretty when we see it along the roadside. Placed under a microscope, however, it is astonishing the amount of beauty it reveals. In some parts of England it is still used for weaving bridal wreaths and has been thus celebrated in flower-lore.
