It is much better to start for nowhere and get there than to start
for somewhere and fall by the wayside. Just keep going, and the
machine will carry you beyond your expectations.

The Professor knew nothing about machinery and less about an
automobile, but where ignorance is bliss it is double-distilled
folly to know anything about the eccentricities of an automobile.

To enjoy automobiling, one must know either all or nothing about
the machine,--a little knowledge is a dangerous thing; on the part
of the guest it leads to all sorts of apprehensions, on the part
of the chauffeur to all sorts of experiments. About five hundred
miles is the limit of a man's ignorance; he then knows enough to
make trouble; at the end of another five hundred he is of
assistance, at the end of the third he will run the machine
himself--your greatest pleasure is in the first five hundred. With
some precocious individuals these figures may be reduced somewhat.

The Professor adjusted his spectacles and looked at the machine:

"A very wonderful contrivance, and one that requires some skill to
operate. From lack of experience, I cannot hope to be of much
practical assistance at first, but possibly a theoretical
knowledge of the laws and principles governing things mechanical
may be of service in an emergency. Since receiving your telegram,
I have brushed up a little my knowledge of both kinematics and
dynamics, though it is quite apparent that the operation of these
machines, accompanied, as it is said, by many restraints and
perturbations, falls under the latter branch. In view of the
possibility--remote, I trust--of the machine refusing to go, I
