Passage 10.13.3
τέχνη τιθασεύειν, προσφέρουσιν ἔτι κειμένοις πίτυος τῆς ἡμέρου καρπὸν προεκλέξαντες ἐκ τῶν ἐλαχίστων ἐλύτρων· ἑτέρας δὲ οὐκ ἂν τροφῆς τό γε παραυτίκα ἅψαιτο τὰ θηρία· τέλος δὲ διαλαβόντες δεσμοῖς ἄγουσι.
They have a skill for taming them: they offer, while the animals still lie on the ground, selected kernels of the fruit of the cultivated pine, carefully picked from their smallest husks. Indeed, at that particular moment, the beasts would touch no other sort of food. Finally, after tying them up securely, they lead them away.
