but the fungus appeared to belong to a different
genus, and the hairy ants, who live in decaying wood and have small
gardens built of bits of wood-fibre, beetle-dung, etc., have not
succeeded in cultivating and selecting Kohl-rabi to the same high
degree. An allied genus of ants, _Cyphomyrmex_, were also found to be
fungus-growers.

This elaborate study, which is illustrated by beautiful plates and
photographs of the mushroom gardens, constitutes, as Mr. Willis (whose
summary has here been followed) remarks, one of the most fascinating
contributions to our knowledge of mycology and of animal industries
which have been made for many years.
