s of the condition
known as double consciousness. On his New England side he was cunning
and calculating, always cautious, measuring his distance before he
risked his stroke, as nicely as if he were throwing his lasso. But
he was liable to intercurrent fits of jealousy and rage, such as the
light-hued races are hardly capable of conceiving, blinding paroxysms of
passion, which for the time overmastered him, and which, if they found
no ready outlet, transformed themselves into the more dangerous forces
that worked through the instrumentality of his cool craftiness.

He had failed as yet in getting any positive evidence that there was
any relation between Elsie and the schoolmaster other than such as might
exist unsuspected and unblamed between a teacher and his pupil. A book,
or a note, even, did not prove the existence of any sentiment. At one
time he would be devoured by suspicions, at another he would try to

in with the old Doctor, on a former occasion, and saw her, will remember
that she was strangely carried away by it, and became almost fearful in
the vehemence of her passion. The sound of the castanets seemed to make
her alive all over. Dick knew well enough what the exhibition would
be, and was almost afraid of her at these moments; for it was like
the dancing mania of Eastern devotees, more than the ordinary light
amusement of joyous youth,--a convulsion of the body and the mind,
rather than a series of voluntary modulated motions.

Elsie rattled out the triple measure of a saraband. Her eyes began to
glitter more brilliantly, and her shape to undulate in freer curves.
Presently she noticed that Dick's look was fixed upon her necklace. His
face betrayed his curiosity; he was intent on solving the
