n accord with G. This dog visits a house next
door to another church, the bell of which sounds F. He never shows the
slightest interest when this bell is rung. When I play compositions in
F-sharp, an English fox-terrier of mine will lie on the floor and listen
for an hour at a time. If I change to the key of E-flat, B-flat, or G, he
will soon leave the room.

A question naturally obtrudes itself here in the matter of the dog which
barks in accord with the church-bell. Does he do this knowingly
(consciously), or is it simply an accident? I believe the former, and
consider it the result of an acquired psychical habitude.

That the dog is conscious (self-conscious) that his voice is in accord
with the bell, I will not venture to assert, for, knowledge on this
point, I take it, is beyond the power of man to acquire. I mean by the
word, "knowingly," when I say that the dog knowingly pitches his voice
in accord with the bell, not that he has any knowledge whatever of
harmony, such as an educated musician possesses, or such even as the
inherited experiences of a thousand years of music-loving ancestors
would naturally impress upon the mind of a civilized European of to-day,
but that he has an acquired imitative faculty (a faculty possessed by
some of the negroes of Central Africa as well as by many other savage
races), of attuning his voice to sounds which are pleasing to his ears.
In support of this proposition I instance the fact of the dog's acquired
habit of barking, which has been developed since his domestication. In
his wild state the dog _never_ barks.

Man himself has done much toward arousing and cultivating the imitative
faculty in the dog (which, in the beginning, impelled this highly
developed animal to _answer_ his master, thus originating the first
vocables--barking--in the canine language), by conversing with him. In
all probability, it is only an "anatomical barrier and a psychical
accident" at best, which prevent the dog from addressing his master
through the agency of speech itself!

The dog's voice is exceedingly pleasing to himself, and, most
frequently, when "baying the moon," he is listening to his own singing,
_not_ (as is generally supposed) as it pours forth from his throat, but
in a more pleasing manner, as it is breathed back to his listening ears
from the airy lips of Echo!

That dogs have discovered that pleasing phenomenon, the echo, I do not
question for a single instant. If a dog which is
