has gloss	eng: :For other uses of the word see Emissary. An emissary (Latin emissarium, from ex and mittere, to send out) is a channel, natural or artificial, by which an outlet is formed to carry off any stagnant body of water. Such channels may be either open or underground; but the most remarkable works of the kind are of the latter description, as they carry off the waters of lakes surrounded by hills.
