Another work may be merely mentioned as illuminating the facts of slavery. It is Frederic Law Olmsted's three volumes of travels in the slave States. He studied them with the eyes of a farmer and a practical man; a well-equipped, fair, and keen observer. His testimony, already touched on in these chapters, is very strong as to the economic mischief of the system, its frequent cruelties, its demoralization of both master and slave, and the absolute need of its ultimate extinction. From his pages we can borrow but one or two passages. The contrasts of slavery are epitomized in two plantations he found side by side in Mississippi. On one the slaves had good food and clothes, were not driven hard, were given three stops in the day for meals, and had the time from Friday night till Monday morning for themselves. In this time the men cultivated gardens and the women washed and sewed. They were smartly dressed, and seemed very contented; many could read and write; on Sundays there was a church service and a Sabbath school taught by their mistress, both of which they could attend or not as they pleased. On the other plantation, owned by a religious woman, the working hours were from 3.30 A. M. to 9 P. M. The slaves had only Sunday free from labor, and on that day there were three services which they had to attend under penalty of a whipping. They were never allowed off the plantation, and were whipped if they talked with slaves from other plantations. Said a neighbor, "They can all repeat the catechism, but they are the dullest, laziest, and most sorrowful negroes I ever saw." As to the possibilities of gradual emancipation, which he favored, Olmsted wrote that in Cuba every slave has the right of buying his own freedom, at a price which does not depend on the selfish exaction of his master, but is either a fixed price or is determined in each case by disinterested appraisers. "The consequence is that emancipations are continually going on, and the free people of color are becoming enlightened, cultivated, and wealthy. In no part of the United States do they occupy the high position which they enjoy in Cuba." So much for the despised Spanish-American. From a still different standpoint--that of the non-slaveholding Southern white--the system was reviewed and scathingly judged in Helper's _The Impending Crisis_. But that, like _Uncle Tom's Cabin_, was not merely a book, but an event, and as such is to be mentioned in its place among events. The general survey of the slave system in itself need not here be carried further. As to its essential character and basal principle, no truer word was ever spoken than that which Mrs. Stowe puts in the mouth of the slaveholder St. Clare:
