Edwin Lee proved himself not ungrateful for the kindness.  In a few years he became one of Mr. Darlington’s most active, trustworthy and intelligent clerks; while his kind, modest, gentlemanly deportment at home, won the favor and confidence of all the family.  With Edwin, Kate grew up as with a brother.  Their intercourse was of the most frank and confiding character.

But there came, at last, a change.  Kate from a graceful sweet-tempered, affectionate girl, stepped forth, almost in a day, it seemed to Edwin, a full-grown, lovely woman, into whose eyes he could not look as steadily as before, and on whose beautiful face he could no longer gaze with the calmness of feeling he had until now enjoyed.

For awhile, Edwin could not understand the reason of this change.  Kate was the same to him; and yet not the same.  There was no distance—­no reserve on her part; and yet, when he came into her presence, he felt his heart beat more quickly; and when she looked him steadily in the face, his eyes would droop, involuntarily, beneath her gaze.

Suddenly, Edwin awoke to a full realization of the fact that Kate was to him more than a gentle friend or a sweet sister.  From that moment, he became reserved in his intercourse with her; and, after a short time, firmly made up his mind that it was his duty to retire from the family of his benefactor.  The thought of endeavoring to win the heart of the beautiful girl, whom he had always loved as a sister, and now almost worshipped, was not, for a moment entertained.  To him there would have been so much of ingratitude in this, and so much that involved a base violation of Mr. Darlington’s confidence, that he would have suffered anything rather than be guilty of such an act.

But he could not leave the home where he had been so kindly regarded for years, without offering some reason that would be satisfactory.  The true reason, he could not, of course, give.  After looking at the subject in various lights, and debating it for a long time, Edwin could see no way in which he could withdraw from the family of Mr. Darlington, without betraying his secret, unless he were to leave the city at the same time.  He, therefore, sought and obtained the situation of supercargo in a vessel loading for Valparaiso.

When Edwin announced this fact to Mr. Darlington, the merchant was greatly surprised, and appeared hurt that the young man should take such a step without a word of consultation with him.  Edwin tried to explain; but, as he had to conceal the real truth, his explanation rather tended to make things appear worse than better.

Kate heard the announcement with no less surprise than her father.  The thing was so sudden, so unlooked for, and, moreover, so uncalled for, that she could not understand it.  In order to take away any pecuniary reason for the step he was about to take, Mr. Darlington, after holding a long conversation with Edwin, made him offers far more advantageous than his proposed expedition could be to him, viewed in any light.  But he made them in vain.  Edwin acknowledged the kindness, in the warmest terms, but remained firm in his purpose to sail with the vessel.
