Social distempers, like those of the body, are accompanied by the agency of restoration. The sick man, debilitated and suffering from the violence of his symptoms, seeks his bed and calls his physician, thus placing himself in the most favorable attitude for recovery. Were it not for the realization of his distress, he might, in default of rest and medicine, hurry himself into the grave. So, within some of the more morally sensitive souls of the country, commenced to be experienced an unhappy sense of our degradation and depth of misery. Cries of warning and expostulation began to be heard in the land. One of these rose higher than the others, even echoing down through the years to our own time. It was that of Dr. Benjamin Rush, of Philadelphia. Standing in relation to Dr. Clark as of a voice crying in the wilderness, his work in the field of temperance merits more than a casual remark. It consists of but a small, thirty-two page pamphlet, but condensed in its limited proportions is a world of moral dynamite. It bears the title: "An Inquiry Into the Effects of Ardent Spirits Upon the Human Body and Mind, With an Account of the Means of Preventing and of the Remedies for Curing Them," and was published in 1785. So great had been the salutary influence of this little treatise, that the centennial anniversary of its issue was duly celebrated at Philadelphia. It is not a profound essay; indeed, the wayfaring man, though a fool, may easily grasp its lucid ideas. Neither is it calculated to be very offensive to any class of readers, for it takes issue only with distilled liquors, recommending fermented beverages as substitutes. Moreover, the confirmed toper can read the pamphlet, not only without umbrage, but with interest; for there is an intensity, a directness of statement in its style which hold the reader, even to this day, with the simple art of its literary merit. Besides, there appears running through its pages a quaint humor, which no doubt had much to do with gaining its popularity throughout the length and breadth of the land. [Illustration: From Your Father, B. J. Clark.] A unique and ingenious feature of the essay is the author's "Moral and Physical Thermometer," which forms its frontispiece. On the ascending scale, "Strong Beer" is placed in the lowest and "Water" at the highest degree, with remarks indicating improving mental and physical conditions in the rising course. On the descending scale, "Punch" occupies the highest while "Rum day and night" is found at the lowest place, accompanied between points by a fearfully intensifying array of vices, diseases and penalties. In this connection might be quoted the author's interpretation of a familiar myth: "The fable of Prometheus, on whose liver a vulture was said to prey constantly, as a punishment for his stealing fire from heaven, was intended to illustrate the painful effects of ardent spirits upon that organ of the body."
