"And have you seen devils among them?" asked Father Ferapont.
"Among them? Among whom?" asked the little monk, timidly.
"I went to the Father Superior on Trinity Sunday last year, I haven't been since. I saw a devil sitting on one man's chest hiding under his cassock, only his horns poked out; another had one peeping out of his pocket with such sharp eyes, he was afraid of me; another settled in the unclean belly of one, right in the guts, another was hanging round a man's neck, and he was carrying him about without seeing him."
"You—can see spirits?" the little monk inquired.
"I tell you I can see, I can see through them. When I was coming out from the Superior's I saw one hiding from me behind the door, and a big one, a yard and a half or more high, with a thick long gray tail, and the tip of his tail was in the crack of the door and I was quick and slammed the door, pinching his tail in it. He squealed and began to struggle, and I made the sign of the cross over him three times. And he died on the spot like a crushed spider. He must have rotted there in the corner and be stinking, but they don't see, they don't smell it. It's a year since I have been there. I reveal it to you, as you are a stranger."
"Your words are terrible! But, holy and blessed Father," said the little monk, growing bolder and bolder, "is it true, as they noise abroad even to distant lands about you, that you are in continual communication with the Holy Ghost?"
"He does fly down at times."
"How does he fly down? In what form?"
"As a bird."
"The Holy Ghost in the form of a Dove?"
"There's the Holy Ghost and there's the Holy Spirit. The Holy Spirit can appear as other birds—sometimes as a swallow, sometimes a goldfinch and sometimes as a blue tit."
"How do you know him from an ordinary tit?"
"He speaks."
"How does he speak, in what language?"
"Human language."
"And what does he tell you?"
"Why, today he told me that a fool would visit me and would ask me unseemly questions. You want to know too much, monk."
