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.
A 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).
_Hilaire Belloc_.
