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.)
