It can not be asserted that ostriches are polygamous, though they often appear to be so.

When caught they are easily tamed, but are of no use in their domesticated state.
The egg is possessed of very great vital power.

One kept in a room during more than three months, in a temperature about 60 Deg., when broken was found to have a partially-developed live chick in it.

The Bushmen carefully avoid touching the eggs, or leaving marks of human feet near them, when they find a nest.

They go up the wind to the spot, and with a long stick remove some of them occasionally, and, by preventing any suspicion, keep the hen laying on for months, as we do with fowls.
