Careful observation is impossible while the branches are shaken by the _mistral_.

I detach the twig and lay it gently upon the ground.

The insect takes no notice of its removal; it continues its work.

I crouch beside it, sheltered from the storm behind a mass of underwood, and watch operations.
Shod with adhesive sandals which later on, in my laboratory, will allow it rapidly to climb a vertical sheet of glass, the elephant-beetle is solidly established on the smooth, steep curvature of the acorn.

It is working its drill.
