Scarlet and Hyssop

It has been ordained by the wisdom of Nature that the same fact shall strike the majority of her foolish children almost simultaneously. This phenomenon can hardly have escaped the most casual observer; the majority of swallows, for instance, in any given area will agree, practically in the same week, that our English autumn is no longer tolerable, and with consenting twitterings set their heads southwards; or in the spring, again, one may observe that in any given field daisies and buttercups will determine, only to be nipped by unpunctual frosts, that it is now time to come out, while even man, that most vacillating and least uniform of all created things, has a certain sympathy in his sensations; the sap stirs with moderately equal effervescence in the most dissimilar units; and without further preamble, to take the case in point, London settles without consultation, but with considerable unanimity, when spring may be considered to have stopped and summer to have begun.
