ost probable that all the land, with the
exception of Friesland, was considered a part of Gaul.

Three great rivers--the Rhine, the Meuse, and the Scheld--had deposited
their slime for ages among the dunes and sand banks heaved up by the
ocean around their mouths. A delta was thus formed, habitable at last for
man. It was by nature a wide morass, in which oozy islands and savage
forests were interspersed among lagoons and shallows; a district lying
partly below the level of the ocean at its higher tides, subject to
constant overflow from the rivers, and to frequent and terrible
inundations by the sea.

The Rhine, leaving at last the regions where its storied lapse, through
so many ages, has been consecrated alike by nature and art-by poetry and
eventful truth--flows reluctantly through the basalt portal of the
Seven Mountains into the open fields which extend to the German sea.
After entering this vast meadow, the stream divides itself into two
branches, becoming thus the two-horned Rhine of Virgil, and holds in
these two arms the island of Batavia.

The Meuse, taking its rise in the Vosges, pours itself through the
Ardennes wood, pierces the rocky ridges upon the southeastern frontier of
the Low Countries, receives the Sambre in the midst of that picturesque
anthracite basin where now stands the city of Namur, and then moves
toward the north, through nearly the whole length of the country, till it
mingles its waters with the Rhine.

The Scheld, almost exclusively a Belgian river, after leaving its
fountains in Picardy, flows through the present provinces of Flanders and
Hainault. In Caesar's time it was suffocated before reaching the sea in
quicksands and thickets, which long afforded protection to the savage
inhabitants against the Roman arms; and which the slow process of nature
and the untiring industry of man have since converted into the
archipelago of Zealand and South Holland. These islands were unknown to
the Romans.

Such were the rivers, which, with their numerous tributaries, coursed
through the spongy land. Their frequent overflow, when forced back upon
their currents by the stormy sea, rendered the country almost
uninhabitable. Here, within a half-submerged territory, a race of
wretched ichthyophagi dwelt upon terpen, or mounds, which they had
raised, like beavers, above the almost fluid soil. Here, at a later day,
the same race chained the tyrant Ocean and his mighty streams into
subserviency, forci
