Our native bean-eaters have mistaken the stranger; they have not had time as yet to grow familiar with it, or to appreciate its merits; they have prudently abstained from touching the _ayacot_, whose novelty awoke suspicion.

Until our own days the Mexican bean remained untouched: unlike our other leguminous seeds, which are all eagerly exploited by the weevil.
This state of affairs could not last.

If our own fields do not contain the insect amateur of the haricot the New World knows it well enough.

By the road of commercial exchange, sooner or later some worm-eaten sack of haricots must bring it to Europe.

The invasion is inevitable.
According to documents now before me, indeed, it has already taken place.
