The same steps which had rendered all
scientific notions practicable, had gradually eliminated the faults
which originally existed, and they were now becoming good, sound,
available instruments. At present, he could only regard this electric
launch as a luxury. He had hoped that Mr. Reckenzaun would have been
able to say something which would have enabled poor men to look forward
to the time when they might enjoy themselves in them on the river; but
he was told at Vienna, when he enjoyed two or three trips in this boat
on the Danube, that her cost would be about L800, which was a little too
much for most people. They wanted something more within their reach,
so that at various points on the river they might see small engines
constantly at work supplying energy to secondary batteries, and so that
they might start on a Friday evening, and go up as far as Oxford, or
higher, and come down again on Monday morning. He must congratulate Mr.
Reckenzaun on the excellent diagrams he had constructed.
