But when those whom they sent never returned, they took it amiss that they should be condemned always to be sending people and not getting them back, and so they carry the offerings, wrapped in straw, to their borders, and tell their neighbors to send them on from their own country to the next;

and the offerings, it is said, come by this conveyance to Delos [25.2833,37.4] (Perseus)Delos. I can say of my own knowledge that there is a custom like these offerings; namely, that when the Thracian and Paeonian women sacrifice to the Royal Artemis, they have straw with them while they sacrifice.
