palisade, for we found a rotted cliff near by where we could get
all the flat building-stone we needed, and so we constructed a
stone wall entirely around the buildings. It was in the form of
a square, with bastions and towers at each corner which would
permit an enfilading fire along any side of the fort, and was
about one hundred and thirty-five feet square on the outside,
with walls three feet thick at the bottom and about a foot and

in the line of official business since our encounter--a condition
of armed neutrality which suited me to a T. We have just finished
it, the last touches being put on today. I quit about a week ago
and commenced working on this chronicle for our strange adventures,
which will account for any minor errors in chronology which may
have crept in; there was so much material that I may have made
some mistakes, but I think they are but minor and few.

I see in reading over the last few pages that I neglected to
state that Lys finally discovered that the Neanderthal man
possessed a language. She had learned to speak it, and so have
I, to some extent. It was he--his name he says is Am, or Ahm--
who told us that this country is called Caspak. When we asked
him how far it extended, he waved both arms about his head in an
all-including gesture which took in, apparently, the entire universe.

has assured us that he will not permit his fellows to harm us.
He calls us Galus and says that in a short time he will be a Galu.
It is not quite clear to us what he means. He says that there are
many Galus north of us, and that as soon as he becomes one he will
