Emissaries (#). [L. emissarius, fr.
emittere, emissum, to send out: cf. F.
émissaire. See Emit.] An agent employed to
advance, in a covert manner, the interests of his employers; one sent
out by any power that is at war with another, to create

Buzzing emissaries fill the ears
Of listening crowds with jealousies and fears.

Syn. -- Emissary, Spy. A spy is one
who enters an enemy's camp or territories to learn the condition of
the enemy; an emissary may be a secret agent appointed not
only to detect the schemes of an opposing party, but to influence
their councils. A spy must be concealed, or he suffers death;
an emissary may in some cases be known as the agent of an
adversary without incurring similar hazard.
