My visions of poverty and future distress vanished; the present seemed gilded with new charms, and the future appeared no longer to be dreaded. But you can better imagine, than I describe, the revolution of my feelings. “I have since endeavored to circulate this book as widely as my limited opportunities permit, and shall continue to do so, believing it to be the most useful work that has made its appearance.” The next extract, from an inhabitant of Pennsylvania, we have selected chiefly as it furnishes a beautiful, and, alas! a rare, example, of that parental conscientiousness which scruples to impart existence where it cannot also impart the conditions necessary to render that existence happy. In this view, the control in question is indeed all-important. Were such virtue as this cultivated in mankind generally, how soon might the very seeds of disease die out among us, instead of bearing, as now, their poison-fruit from generation to generation! and how far might human beings, in succeeding ages, surpass their forefathers in strength, in health, and in beauty! This view of the subject is to the physiologist, to the philosopher, to every friend of human improvement, a most interesting one. ‘So long,’ to use the words of an eloquent lecturer, ‘as the tainted stream is unhesitatingly transmitted through the channel of nature, from parent to offspring, so long will the text be verified which “visits the sins of the fathers on the children, even to the third and fourth generation.”’ And so long, we would add, will mankind—wise and successful whenever there is question of improving the animal races—be blind in perceiving, and listless in securing, that far nobler object, the physical, and thereby—in a measure—the mental and moral improvement of our own. Here is the extract which led to these remarks:— “I was born of poor parents, and early left an orphan. When of age, though my circumstances promised poorly for the support of a family, I desired to marry, knowing that a good wife would greatly add to my happiness. The preventive spoken of in your book presented itself to my mind, and for seven years that I have now been married, it has been used. I was successful in business, and acquired the means of maintaining a family; but still I have been unwilling, because my constitution is such a one as I think a parent ought not to transmit to his offspring. I prefer not to give birth to sentient beings, unless I can give them those advantages, physical as well as moral and intellectual, which are essential to human happiness.” From the letter of an aged French gentleman, who holds a public office in the western country, I translate the following; and I would to heaven that every young man and woman in these United States could read it:
