Miss Keller does not as a rule read very fast, but she reads
deliberately, not so much because she feels the words less
quickly than we see then, as because it is one of her habits of
mind to do things thoroughly and well. When a passage interests
her, or she needs to remember it for some future use, she
flutters it off swiftly on the fingers of her right hand.
Sometimes this finger-play is unconscious. Miss Keller talks to
herself absent-mindedly in the manual alphabet. When she is
walking up or down the hall or along the veranda, her hands go
flying along beside her like a confusion of birds' wings.

There is, I am told, tactile memory as well as visual and aural
memory. Miss Sullivan says that both she and Miss Keller remember
"in their fingers" what they have said. For Miss Keller to spell
a sentence in the manual alphabet impresses it on her mind just
as we learn a thing from having heard it many times and can call
back the memory of its sound.

Like every deaf or blind person, Miss Keller depends on her sense
of smell to an unusual degree. When she was a little girl she
smelled everything and knew where she was, what neighbour's house
she was passing, by the distinctive odours. As her intellect grew
she became less dependent on this sense. To what extent she now
identifies objects by their odour is hard to determine. The sense
of smell has fallen into disrepute, and a deaf person is
reluctant to speak of it. Miss Keller's acute sense of smell may
account, however, in some part for that recognition of persons
and things which it has been customary to attribute to a special
