control the upper reaches of the stream. It was not difficult to find
such a location. It lay three miles below town, at the junction of the
north and south branches of Coldriver. The juncture was in a big,
marshy, untillable flat, from which hills rose abruptly. From the
easterly end of the flat the augmented river squeezed in a roaring
rapids through a sort of bottle neck.

Scattergood stood on the hillside and looked upon this with satisfied
eye.

"A dam across that bottle neck," he said to himself, "will flood that
flat. Reg'lar reservoy. Millpond. Git a twenty-foot fall here easy,
maybe more. Calc'late that'll run about any mill folks'll want to build.
And," he scratched his head as a sort of congratulation to it for its
efficiency, "I can't study out how anybody's agoin' to git logs past
here without dickerin' with the man who owns the dam...." Plenty of
water twelve months a year to give free power; a flat made to order for
reservoir or log pond; a complete and effective blockade of both
branches of the river which came down from a country richly timbered! It
was one of the spots Scattergood had dreamed of.

Scattergood knew perfectly well he could not stop a log from passing his
dam. Nor could he shut off the stream. Any dam he built must have a
sluice which could be opened for the passage of timber, and all timber
was entitled to "natural water." But, as he well knew, "natural water"
was not always enough. A dam at this point would raise the level on the
bars of the flat so that logs would not jam, and a log which used the
high water caused by the dam must pay for it. What Scattergood had in
mind was a dam and boom company. It was his project to improve the
river, to boom backwaters, to dynamite ledges, to make the river
