Farther on it flows through broad valleys, which, however, present no very attractive features.
September 7th.
Early in the morning we crossed the pretty Vikensee, which distinguishes itself, like all Swedish lakes, by the multitude of its islands, cliffs, and rocks.

These islands are frequently covered with trees, which make the view more interesting.
The lake is 306 feet above the level of the North Sea, and is the highest point of the journey; from thence the locks begin to descend.

The number of ascending and descending locks amounts to seventy-two.
A short canal leads into the Boltensee, which is comparatively free from islands.

The passage across this little lake is very charming; the shores are diversified by hills, woods, meadows, and fields.

After it comes the Weltersee, which can be easily defended by the beautiful fortress of Karlsborg.
