forks, magnets, batteries, coils of wire, tin
trumpets, and cigar-boxes. No one outside of
the Sanders family was allowed to enter it, as
Bell was nervously afraid of having his ideas
stolen. He would even go to five or six stores
to buy his supplies, for fear that his intentions
should be discovered. Almost with the secrecy
of a conspirator, he worked alone in this cellar,
usually at night, and quite oblivious of the fact
that sleep was a necessity to him and to the
Sanders family.

"Often in the middle of the night Bell would
wake me up," said Thomas Sanders, the father
of Georgie. "His black eyes would be blazing
with excitement. Leaving me to go down to
the cellar, he would rush wildly to the barn and
begin to send me signals along his experimental
wires. If I noticed any improvement in his
machine, he would be delighted. He would leap
and whirl around in one of his `war-dances' and
then go contentedly to bed. But if the experiment
was a failure, he would go back to his workbench
and try some different plan."

The second pupil who became a factor--a
very considerable factor--in Bell's career was a
fifteen-year-old girl named Mabel Hubbard, who
had lost her hearing, and consequently her speech,
through an attack of scarlet-fever when a baby.
