What Was Manna?

        It is supposed that the manna of the Israelites was a saccharine exudation of a species of tamarisk, the
sap of which was set flowing by an insect. Several trees yield manna, as the flowering ash of Sicily and
the eucalyptus of Australia. In India a sweet exudation comes from the bamboo, and a similar substance
is obtained from the sugar-pine and common reed of our own country.
