The Tree Frog always knew the right thing to do, and he said "Pukr-r-rup!" so loudly that all stopped talking at once. When they were quiet he said: "We will now listen to a duet, 'Katy,' by the two singers who are up the tree. All please join in the chorus." So it was begun again, and both the leaders were good-natured, and all the Katydids below joined in with "did or didn't, did or didn't, did or didn't." And that was the end of the quarrel.
