guano

The guano, so extensively used for manure, is full of the most beautiful infusoria, some of them splendidly iridiscent; and there is no better method of testing the genuineness of this useful substance than by the microscope.

A roof made of guano palm fronds will last up to 15 years, although Maya harvesters point out that the leaves must be cut when the moon is full; otherwise, the stems become susceptible to insect damage.

The Animals of these Islands, are some Hogs, Lizards, and Guanoes; and some of those Creatures mentioned in Chap. XI. which are like, but much bigger than the Guano.
