Then Sindre put a lump of iron into the fire.
He said to Brok, "Now blow as hard as you can."
And Sindre went out. Brok blew and blew. The same mean fly came again, and bit him on the forehead. It bit so hard that the blood ran into his eyes.
Brok put up his hand to brush away the fly.
Just then Sindre came back.
He took the hammer out of the fire.
