Student: But I don't know who you are.
Voice: Oh yes, you do.
Student: Who are you?
Voice: Your old schoolfellow, Tom ——. You know me.
Student: Why, he's in Canada.
Voice (sharply): No he ain't, he's here; but be quick.
Student (opening the lid): Perhaps he's come by the underground railroad? Hallo!
Voice (not so muffled, as described in directions): Now then, give us a hand.
Student (closing the lid or door sharply): No, I won't.
Voice (as before): Have pity (Tom, or Jack, or Mr. ——. as the case may be), or I shall be choked.
