Against the mosquitos that abound, the following have been devised by them: those who dwell higher up than the marshy country are well served by the towers where they ascend to sleep, for the winds prevent the mosquitos from flying aloft; those living about the marshes have a different recourse, instead of the towers. Every one of them has a net, with which he catches fish by day, and at night he sets it around the bed where he rests, then creeps under it and sleeps. If he sleeps wrapped in a garment or cloth, the mosquitos bite through it; but through the net they absolutely do not even venture.
