burst and overwhelmed the neighboring country. What known force but that combination of molecular force known as capillarity can supply and sustain the waters of the lake and swamp above described?"
It is hard to answer as to the supply, but it is obvious that the force that sustains the lake at its present height is not molecular, unless a lock be a molecule. "The outlets at the canal locks," said old Mr. Wallace, "are inadequate to let out the overflow, and it has to flood the land." He was speaking of the pane-like openings in the locks to lower the water.
But suppose the locks were opened altogether, and left open, what would be the result?
The middle level of the Dismal Swamp Canal is, or is supposed to be, eight feet deep. If the middle locks were opened, the lake would be lowered eight feet, and the whole swamp west of the lake would drain into it, while that portion to the east would drain into the canal.
If there be a doubt of the consequence, look at some of the wonderful farm lands lying east of the canal from Deep Creek to South Mills. Miles and miles of fertility almost incomparable on the surface of the earth. Half a century ago every foot of this land was Dismal Swamp, forsaken morass, full of reptiles and wild animals.
