As a friend to the children commend me the Yak.
 You will find it exactly the thing:
 It will carry and fetch, you can ride on its back,
 Or lead it about with a string.

The Tartar who dwells on the plains of Thibet
   (A desolate region of snow)
 Has for centuries made it a nursery pet,
 And surely the Tartar should know!

Then tell your papa where the Yak can be got,
 And if he is awfully rich
 He will buy you the creature -- or else he will not. 
   (I cannot be positive which.)
