So unlucky, indeed, does the left hand at last become that merely to
mention it is an evil omen; and so the Greeks refused to use the true
old Greek word for left at all, and preferred euphemistically to
describe it as _euonymos_, the well-named or happy-omened. Our own
_left_ seems equally to mean the hand that is left after the right has
been mentioned, or, in short, the other one. Many things which are lucky
if seen on the right are fateful omens if seen to leftward. On the other
hand, if you spill the salt, you propitiate destiny by tossing a pinch
of it over the left shoulder. A murderer's left hand is said by good
authorities to be an excellent thing to do magic with; but here I cannot
speak from personal experience. Nor do I know why the wedding-ring is
worn on the left hand; though it is significant, at any rate, that the
mark of slavery should be put by the man with his own right upon the
inferior member of the weaker vessel. Strong-minded ladies may get up an
agitation if they like to alter this gross injustice of the centuries.

One curious minor application of rights and lefts is the rule of the
road as it exists in England. How it arose I can't say, any more than I
can say why a lady sits her side-saddle to the left. Coachmen, to be
sure, are quite unanimous that the leftward route enables them to see
how close they are passing to another carriage; but, as all continental
authority is equally convinced the other way, I make no doubt this is a
mere illusion of long-continued custom. It is curious, however, that the
English usage, having once obtained in these islands, has influenced
railways, not only in Britain, but over all Europe. Trains, like
carriages, go to the left when they pass; and this habit, quite natural
in England, was transplanted by the early engineers to the Continent,
where ordinary carriages, of course, go to the right. In America, to be
sure, the trains also go right like the carriages; but then, those
