question: My first is in boulder and I have a stone,  My second is thrice in an apple alone,  My third may be found at the end of a hem,  My fourth starts a stick and a stop and a stem,  My fith's in the middle of pop but not pip,  My sixth is the second you'll find in a snip.   My first half can stop up a broad river's flow,  My second half no daughter, the other you know.   I'm found in pudden and pie and good wine,  And I know all your names, so can you tell me mine?
