The number of silent devils was countless. Apparently they were from the lower classes, for they displayed no marks of strength or power. Their voices were rather a confusion of sounds from which no definite answers could be distinguished. There was no articulate speech, rather a pitiful moaning and subdued howling. They could put up little resistance against the powerful effects of exorcism. It seemed as though they came and left in hordes, one crowd being relieved by others of the same type. They reminded one of a traveler who is suddenly overtaken by a swarm of mosquitoes. A few puffs of tobacco drive them away, but in short order they return and pester him again.
