in the near region of Great Falls, a leaden plate bearing the
arms of France, and raised a monument above it, which the Verendryes named
_Beauharnois_. It is stated that this monument was erected on a
river-bluff, between bowlders, and that it was twenty feet in diameter.

There are people who claim to have discovered this monument, but they fail
to produce the leaden plate with the arms of France that the explorers
buried. The search for this hidden plate will one day begin, and the
subject is likely greatly to interest historical societies in Montana, and
to become a very poetic mystery.

Into this wonder-land of waterfalls, sun-dances, and legends, our young
explorers came, now paddling in their airy canoe, now bearing the canoe on
their backs around the falls.

Mr. Mann's white face was a surprise to the native tribes that they met on
the way, but Benjamin's brightness and friendly ways made the journey of
both easy.

They came to the Black Eagle Falls. The great nest still was there. It was
as is described in the book of the early explorers.

It hung over the mists of the rapids, and, strangely enough, there were
revealed three black plumes in the nest.

Benjamin beheld these plumes with a kind of religious awe. His eyes
dilated as he pointed to them.

"They are for me," he said. "One for me, one for father, and one for you.
I'll get them all."

He glided along a shelf of rocks toward the little island, and mounted the
tree. The black eagles were yet there, though their nest was empty. He
passed up the tree under the wings of the eagles, and came down with a
handful of feathers.

"The book was true," said he.

They went to Medicine River, now called the Sun River, and there witnessed
a Sun-dance.

It was a scene to tempt a brilliant painter or poet. The chiefs and
warriors were arrayed in crystals, quartz, and every bright product of the
earth and river that would reflect the glory of the sun.

They returned from where the city of Great Falls is now, back to the
mountains and to the tributaries of the Columbia. Benjamin appeared
before his father, on his return, with a crest of black eagle's plumes,
and this crest the young Indian knight wore until the day of his death.

"I shall wear mine always," he said to his father. "You wear yours."

"Yes," said his father, with a face that showed a full heart.

"Both together," said Benjamin.

"Both together," replied Umatilla.

"Always?" said Benjamin.
