We can be but partially acquainted even with the events which actually influence our course through life, and our final destiny. There are innumerable other events if such they may be called which come close upon us, yet pass away without actual results, or even betraying their near approach, by the reflection of any light or shadow across our minds. Could we know all the vicissitudes of our fortunes, life would be too full of hope and fear, exultation or disappointment, to afford us a single hour of true serenity. This idea may be illustrated by a page from the secret history of David Swan.
