It is much to be regretted that the slavocrats look at but one side of the question. Of all the fanatics in the country, they have, of late, become the most unreasonable and ridiculous. Let them deliberately view the subject of slavery in all its aspects and bearings, and if they are possessed of honest hearts and convincible minds, they will readily perceive the grossness of their past errors, renounce their allegiance to a cause so unjust and disgraceful, and at once enroll themselves among the hosts of Freedom and the friends of universal Liberty. There are thirty-one States in the Union; let them drop California, or any other new free State, and then institute fifteen comparisons, first comparing New-York with Virginia, Pennsylvania with Carolina, Massachusetts with Georgia, and so on, until they have exhausted the catalogue. Then, for once, let them be bold enough to listen to the admonitions of their own souls, and if they do not soon start to their feet _demanding_ the abolition of slavery, it will only be because they have reasons for suppressing their inmost sentiments. Whether we compare the old free States with the old slave States, or the new free States with the new slave States, the difference, unmistakable and astounding, is substantially the same. All the free States are alike, and all the slave States are alike. In the former, wealth, intelligence, power, progress, and prosperity, are the prominent characteristics; in the latter, poverty, ignorance, imbecility, inertia, and extravagance, are the distinguishing features. To be convinced, it is only necessary for us to open our eyes and look at facts--to examine the _statistics_ of the country, to free ourselves from obstinacy and prejudice, and to unbar our minds to convictions of truth. Let figures be the umpire. Close attention to the preceding and subsequent tables is all we ask; so soon as they shall be duly considered and understood, the primary object of this work will have been accomplished. Not content with eating out the vitals of the South, slavery, true to the character which it has acquired for insatiety and rapine, is beginning to make rapid encroachments on new territory; and as a basis for a few remarks on the blasting influence which it is shedding over the broad and fertile domains of the West, which in accordance with the views and resolutions offered by the immortal Jefferson, should have been irrevocably dedicated to freedom, we beg leave to call the attention of the reader to another presentation of the philosophy of free and slave labor.
