They penetrated by their thickest extremities no less than
from eighteen to twenty-four feet into the earth; and one of the
trees having by accident struck against another, it instantly
cleft it through its whole length, as if it had been struck by
lightning.
After the trees had descended the slide, they were collected
into rafts upon the lake, and conducted to Lucerne. From thence
they descended the Reuss, then the Aar to near Brugg, afterwards
to Waldshut by the Rhine, then to Basle, and even to the sea when
it was necessary.
It is to be regretted that this magnificent structure no
longer exists, and that scarcely a trace of it is to be seen upon
the flanks of Mount Pilatus. Political circumstances having taken
away the principal source of demand for the timber, and no other
market having been found, the operation of cutting and
transporting the trees necessarily ceased.(4*)
Professor Playfair, who visited this singular work, states,
that six minutes was the usual time occupied in the descent of a
tree; but that in wet weather, it reached the lake in three
minutes.
