"Boil it down a little, and give it a lower crust, and I
should think it would make a very good custard-pie," said Jack.

We found Niobrara to be a little place of a few hundred
houses. We went into camp on the edge of the town, where we
stayed the next day, as it was Sunday. Early Monday morning we
were out on the road which led along the banks of the Niobrara
River. We were somewhat surprised at the smallness of this
stream. It was of considerable width but very shallow, and in
many places bubbled along over the rocks like a wide brook. We
spoke of its size to a man whom we met. Said he:

"Yes, it ain't no great shakes down here around its mouth,
but you just wait till you get up in the neighborhood of its
head-waters. It's a right smart bit of a river up there."

"But I thought a river was usually bigger at its mouth than
at its source," I said.

"Depends on the country it runs through," answered the man.
"Some rivers in these parts peter out entirely, and don't have no
mouth a' tall--just go into the ground and leave a wet spot. This
here Niobrara comes through a dry country, and what the sun don't
dry up and the wind blow away the sand swallers mostly, though
some water does sneak through, after all; and in the spring it's
about ten times as big as it is now. The Niobrara goes through
the Sand Hills. Anything that goes through the Sand Hills comes
out small. You fellers are going through the Sand Hills--you'll
come out smaller than you be now."
