In the constant struggle between the innocent and the artful, the latter have the advantage, so long as they confine themselves to familiar interests.  But the moment the former conquer their disgust for the study of vice, and throw themselves upon the protection of their own high principles, they are far more effectually concealed from the calculations of their adversaries than if they practised the most refined of their subtle expedients.  Nature has given to every man enough of frailty to enable him to estimate the workings of selfishness and fraud, but her truly privileged are those who can shroud their motives and intentions in a degree of justice and disinterestedness, which surpass the calculations of the designing.  Millions may bow to the commands of a conventional right, but few, indeed, are they who know how to choose in novel and difficult cases.  There is often a mystery in virtue.  While the cunning of vice is no more than a pitiful imitation of that art which endeavors to cloak its workings in the thin veil of deception, the other, in some degree, resembles the sublimity of infallible truth.

Thus men too much practised in the interests of life, constantly overreach themselves when brought in contact with the simple and intelligent; and the experience of every day proves that, as there is no fame permanent which is not founded on virtue, so there is no policy secure which is not bottomed on the good of the whole.  Vulgar minds may control the concerns of a community so long as they arc limited to vulgar views; but woe to the people who confide on great emergencies in any but the honest, the noble, the wise, and the philanthropic; for there is no security for success when the meanly artful control the occasional and providential events which regenerate a nation.  More than half the misery which has defeated as well as disgraced civilization, proceeds from neglecting to use those great men that are always created by great occasions.

Treating, as we are, of the vices of the Venetian system, our pen has run truant with its subject, since the application of the moral must be made on the familiar scale suited to the incidents of our story.  It has already been seen that Gelsomina was intrusted with certain important keys of the prison.  For this trust there had been sufficient motive with the wily guardians of the jail, who had made their calculations on her serving their particular orders, without ever suspecting that she was capable of so far listening to the promptings of a generous temper, as might induce her to use them in any manner prejudicial to their own views.  The service to which they were now to be applied proved that the keepers, one of whom was her own father, had not fully known how to estimate the powers of the innocent and simple.
