The actual loss of _intellectual_ power, which tobacco has hitherto occasioned, and is still causing, in this Christian nation, is immense. How immense, it is impossible accurately to calculate. Many a man who might have been a giant, has not risen above mediocrity; and many a man who might have been respectable and useful, has sunk into obscurity, and buried his talents in the earth. This is a consideration of deepest interest to every philanthropist, patriot, and Christian in the land, and especially to all our youth. We live at a time, and under circumstances, which call for the exertion of all our intellectual strength, cultivated, improved and sanctified, to the highest measure of possibility. Error, ignorance, and sin, must be met and vanquished; they must be met and vanquished by light and love. The eye of angels is upon us,--the eye of God is upon us,--and shall we fetter, and palsy, and ruin our intellectual capabilities, for the paltry pleasure of using one of the most poisonous, loathsome, and destructive weeds found in the whole vegetable kingdom? Let us rather shake off this abominable practice, and rise, as individuals and as a nation, in all our intellectual potency,--and let us go forth from day to day, to the noble purposes of our destiny, untrammelled by the quid, or the pipe, or the snuff-box; and before another generation shall lie down in the grave, our efforts and our example may cause the light of human science, and the light of civil and religious liberty, and the light of Bible truth, to blaze through all our valleys, and over all our hills, from Greenland to Cape Horn,--and with a lustre that shall illumine the world. I maintain my position, IV. From a consideration of the ruinous effects of tobacco upon public and private _morals_. The ruinous effects of tobacco upon public and private morals, are seen in the idle, sauntering habits, which the use of it engenders,--in the benumbing, grovelling, stupid sensations which it induces,--but especially in perpetuating and extending the practice of using intoxicating drinks. Governor Sullivan has truly said, "that the tobacco pipe excites a demand for an extraordinary quantity of some beverage to supply the waste of glandular secretion, in proportion to the expense of saliva; and ardent spirits are the common substitutes; and the smoker is often reduced to a state of dram drinking, and finishes his life as a sot." Dr. Agnew has truly said, that "the use of the pipe leads to the immoderate use of ardent spirits." Dr. Rush has truly said, "that smoking and chewing tobacco, by rendering water and other simple liquors insipid to the taste, dispose very much to the stronger stimulus of ardent spirits; hence [says he] the practice of smoking cigars, has been followed by the use of brandy and water as common drink."
