lights of the Aurora Borealis are in Lancashire 'the Merry Dancers';
clouds piled up in a particular fashion are in many parts of England
styled 'Noah's Ark'; the puff-ball is 'the Devil's snuff-box'; the
dragon-fly 'the Devil's darning-needle'; a large black beetle 'the
Devil's coach-horse.' Any one who has watched the kestrel hanging
poised in the air, before it swoops upon its prey, will acknowledge the
felicity of the name 'windhover,' or sometimes 'windfanner,' which it
popularly bears. [Footnote: In Wallace's _Tropical Nature_ there is a
beautiful chapter on humming birds, and the names which in various
languages these exquisite little creatures bear.] The amount is very
large of curious legendary lore which is everywhere bound up in words,
and which they, if duly solicited, will give back to us again. For
example, the Greek 'halcyon,' which we have adopted without change, has
reference, and wraps up in itself an allusion, to one of the most
beautiful and significant legends of heathen antiquity; according to
which the sea preserved a perfect calmness for all the period, the
fourteen 'halcyon days,' during which this bird was brooding over her
nest. The poetry of the name survives, whether the name suggested the
legend, or the legend the name. Take again the names of some of our
precious stones, as of the topaz, so called, as some said, because men
were only able to _conjecture_ ([Greek: topazein]) the position of the
cloud-concealed island from which it was brought. [Footnote: Pliny, _H.
N._ xxxvii. 32. [But this is only popular etymology: the word can
hardly be of Greek origin; see A. S. Palmer, _Folk-Etymology_, p.
589.]]

Very curious is the determination which some words, indeed many, seem
to manifest, that their poetry shall not die; or, if it dies in one
form, that it shall revive in another. Thus if there is danger that,
transferred from one language to another, they shall no longer speak to
