Extract of a letter dated July 2d, 1834, from Mr. NATHAN COLE, of St. Louis, Missouri, to Arthur Tappan, Esq. of this city: "I am not an advocate of the immediate and unconditional emancipation of the slaves of our country, yet _no man has ever yet depicted the wretchedness of the situation of the slaves in colors as dark for the truth_.... I know that many good people _are not aware of the treatment to which slaves are usually subjected_, nor have they any just idea of the extent of the evil." TESTIMONY OF REV. JAMES A. THOME, _A native of Kentucky--Son of Arthur Thome Esq., till recently a Slaveholder._ "Slavery is the parent of more suffering than has flowed from any one source since the date of its existence. Such sufferings too! _Sufferings inconceivable and innumerable--unmingled wretchedness_ from the ties of nature rudely broken and destroyed, the _acutest bodily tortures, groans, tears and blood_--lying forever in weariness and painfulness, in watchings, in hunger and in thirst, in cold and nakedness. "Brethren of the North, be not deceived. _These sufferings still exist_, and despite the efforts of their cruel authors to hush them down, and confine them within the precincts of their own plantations, they will ever and anon, struggle up and reach the ear of humanity."--_Mr. Thome's Speech at New York, May,_ 1834. TESTIMONY OF THE MARYVILLE (TENNESSEE) INTELLIGENCER, OF OCT. 4, 1835. The Editor, in speaking of the sufferings of the slaves which are taken by the internal trade to the South West, says: "Place yourself in imagination, for a moment, in their condition. With _heavy galling chains_, riveted upon your person; _half-naked, half-starved_; your back _lacerated_ with the 'knotted Whip;' traveling to a region where your _condition through time will be second only to the wretched creatures in Hell_. "This depicting is not visionary. Would to God that it was." TESTIMONY OF THE PRESBYTERIAN SYNOD OF KENTUCKY; _A large majority of whom are slaveholders._ "This system licenses and produces _great cruelty_. "Mangling, imprisonment, starvation, every species of torture, may be inflicted upon him, (the slave,) and he has no redress. "There are now in our whole land two millions of human beings, exposed, defenceless, to every insult, and every injury short of maiming or death, which their fellow men may choose to inflict. _They suffer all_ that can be inflicted by wanton caprice, by grasping avarice, by brutal lust, by malignant spite, and by insane anger. Their happiness is the sport of every whim, and the prey of every passion that may, occasionally, or habitually, infest the master's bosom. If we could calculate the amount of wo endured by ill-treated slaves, it would overwhelm every compassionate heart--it would move even the obdurate to sympathy. There is also a vast sum of suffering inflicted upon the slave by humane masters, as a punishment for that idleness and misconduct which slavery naturally produces.
