These experiments do not tell much of importance; they are curious,
and perhaps of sufficient interest to bring before your notice. The
fragments are all preserved in tubes, and labeled, so that any one who
likes to see them can do so.

Of the advantage which a machine which will collapse or fold up when
desired, but retain its form on the road, offers in convenience, it is
unnecessary for me to speak.

Of double machines, the Rucker tandem bicycle seems to me to be in every
respect the best, but I should add that I speak only from imagination
and not from experience. The independent steering, the impossibility of
capsizing forward or sideways, the position of the rider over his work,
the absence of any little wheel with its mud throwing and vibrating
tendencies, combine to make a machine which ought to be superior in
almost every desirable quality to any other; what it may be in practice
I hope to hear in the discussion.

Of double tricycles, the Sociable has been tried by many, and is
practically a failure in so far as traveling quickly and easily
is concerned. The Tandem, though it presents so objectionable an
appearance, seems likely to become a favorite, for it surpasses any
single tricycle, and rivals the bicycle in speed. How it may compare in
comfort or in safety with the single machine, perhaps those few who are
well acquainted with them will say; at any rate, in the case of the
Humber, greater stability is given to the steering, owing to the weight
of the front rider.

Time will not allow me to say more of these machines, or to attack the
