During these preparations the sea became narrower and narrower, and the sailors discovered that they were entering the mouth of a river. The water was fresh, and there was land on both sides. The trirema glided slowly onwards up the sparkling river. The weather was brilliant, and the whole of nature was gloriously peaceful. And how the magnificent merchantman enlivened the great solitude!
On both sides of the river primeval forests, high and thick, met their view. Pine-trees grew right to the water's edge. The river in its eternal course had washed away the earth from the roots, and the hearts of the seamen were moved with solemn awe at the sight, not only of these venerable trees, but even more by that of the naked roots, which resembled the mighty limbs of a giant. 'Here,' they thought, 'man will never succeed in planting corn; here the ground will never be cleared for the building of a city, or even a farmstead. For miles round the earth is woven through with this network of roots, hard as steel. This alone is sufficient to make the dominion of the forest everlasting and unchangeable.'
Along the river the trees grew so close, and their branches were so entangled, that they formed firm, impenetrable walls. These walls of prickly firs were so strong and high that no fortified city need wish for stronger defences. But here and there there was, all the same, an opening in this wall of firs. It was the paths the wild beasts had made on their way to the river to drink. Through these openings the strangers could obtain a glimpse of the interior of the forest. They had never seen anything like it. In sunless twilight there grew trees with trunks of greater circumference than the gate-towers on the walls of Rome. There was a multitude of trees, fighting with each other for light and air. Trees strove and struggled, trees were crippled and weighed down by other trees. Trees took root in the branches of other trees. Trees strove and fought as if they had been human beings.
But if man or beast moved in this world of trees they must have other modes of making their way than those which the Romans knew, for from the ground right up to the top of the forest was a network of stiff bare branches. From these branches fluttered long tangles of gray lichen, transforming the trees into weird beings with hair and beard. And beneath them the ground was covered with rotten and rotting trunks, and one's feet would have sunk into the decayed wood as into melting snow.
