strength of a hundred men. As for his horse Svadilföri, he did more work
by half than even the mighty builder. In the night he dragged the
enormous rocks that were to be used in building the castle, rocks as big
as mountains of the earth; while in the daytime the stranger piled them
into place with his iron arms. The Æsir watched him with amazement;
never was seen such strength in Asgard. Neither TÅ·r the stout nor
Thor the strong could match the power of the stranger. The gods began to
look at one another uneasily. Who was this mighty one who had come among
them, and what if after all he should win his reward? Freia trembled in
her palace, and the Sun and Moon grew dim with fear.

Still the work went on, and the fort was piling higher and higher, by
day and by night. There were but three days left before the end of
winter, and already the building was so tall and so strong that it was
safe from the attacks of any giant. The Æsir were delighted with their
fine new castle; but their pride was dimmed by the fear that it must be
paid for at all too costly a price. For only the gateway remained to be
completed, and unless the stranger should fail to finish that in the
next three days, they must give him Freia with the Sun and Moon.

The Æsir held a meeting upon Ida Plain, a meeting full of fear and
anger. At last they realised what they had done; they had made a bargain
with one of the giants, their enemies; and if he won the prize, it would
mean sorrow and darkness in heaven and upon earth. "How did we happen to
agree to so mad a bargain?" they asked one another. "Who suggested the
wicked plan which bids fair to cost us all that we most cherish?" Then
they remembered that it was Loki who had made the plan; it was he who
had insisted that it be carried out; and they blamed him for all the
trouble.
