How long did the giant stay with his friend in Cornish Ogre

Someone was before me at my water - trough,

And I like a second comer, waiting

Name the poet of these poetic lines.

Who said 'Under the wide and starry sky Dig the grave and let me lie'

Who said this following 

"The Jew Shall have all justice. Soft! No haste,

He shall have nothing but the penalty'

Which nationality the story belongs to 

" How the Camel got its Hump"

What is a Sonnet
