brought it to Mimer.

The smith felt the razor edge of the bright weapon, and said, "This
seems, indeed, a fair fire edge. Let us make a trial of its keenness."

Then a thread of wool as light as thistle-down was thrown upon water,
and, as it floated there, Mimer struck it with the sword. The
glittering blade cleft the thread in twain, and the pieces floated
undisturbed upon the surface of the liquid.

"Well done!" cried the delighted smith. "Never have I seen a keener

But Siegfried took the sword again, and broke it into many pieces; and
for three days he welded it in a white-hot fire, and tempered it with
milk and oatmeal. Then, in sight of the sneering apprentices, a light
ball of fine-spun wool was cast upon the flowing water of the brook;
and it was caught in the swift eddies of the stream, and whirled about
until it met the bared blade of the sword, which was held in
Siegfried's hands. And the ball was parted as easily and clean as the
rippling water, and not the smallest thread was moved out of its place.

man, long-bearded, and clad in a cloud-gray kirtle, and wearing a
sky-blue hood, talking with Siegfried at the smithy door. And they
