"But you said a little while ago that your name was Rap."

"Everybody calls me Rap, because when I go along the road my crutch hits
the stones, and says 'rap--rap--rap.'"

"Here's a dead bird," said Nat, picking something from under the fence.

"It's a White-throated Sparrow," said Rap, "and it's flown against the
telegraph wire in the dark and been killed." "We will take it to uncle
and ask him to tell us all about it."

"Yes, yes," said Dodo, "we will all go"--and Rap hopped off after the
other children so quickly that Olive had hard work to keep up with him.

This time Nat and Dodo did not hesitate outside the study door, but gave
a pound or two and burst into the room.

"Uncle Roy, Uncle Roy, we have seen two birds and written down about
them, but we didn't quite know what to call the front part where the
neck ends and the stomach begins, or the beginning of the tail, and
Olive says there are right names for all these parts. And we found Rap
in the orchard and he only has half a book, and here's a White-throated
Sparrow, and we want to know how it's made and why birds can fly and
why--"

Here the Doctor laughingly stopped them and turned to Olive for a
clearer account of what had taken place in the orchard, while Rap stood
gazing about the room as if he thought that heaven had suddenly opened
to him.
