A frontier-town zoo is a poor thing of bare concrete and iron cages, yet Robin Lampert finds he can't look away from the exhibits, on the humid, jungle-choked colony world of Emeraude.

Hal Clement's 1963 story is a rigorous hard-SF colonization and puzzle tale. Sharp, ingenious golden-age SF. Read it for classic Clement, a meticulously imagined alien ecology and a scientific mystery, where the green world of the title poses a problem only careful observation and reason can solve.
