CHAPTER III.

THE AMOUNT AND EXTENT OF THE TRADE.

We have already discussed the causes of the domestic slave trade. In this chapter it is our purpose, chiefly, to consider its amount and extent.

In this connection our first object will be to determine whether it was carried on as a business before 1808. It appears that there were exchanges of slaves going on among the States and territories before this time, but whether this was anything more than of an occasional or incidental nature is a question.

The statutes of some of the States give some light along this line. South Carolina in 1792 prohibited the introduction of slaves either by land or sea.[98]Delaware, however, as early as 1787, passed a law which recites that: "Sundry negroes and mulattoes, as well freeman as slaves,have been exported and sold into other States, contrary to the principles of humanity and justice, and derogatory to the honor of this State."

This law prohibited their exportation without a permit.[99]It seems to have been something more than merely incidental for it was amended in 1793, as follows:

"That from and after the first Tuesday of October next, the justice of the Court of General Quarter Sessions and Jail Delivery, or any two of them, shall have the like power to grant a licence or permit to export, sell or carry out for sale, any negro or mulatto slave from this State that five justices of the peace in open Sessions now have."[100]

We have evidence to show that, by 1802, Alexandria, in the District of Columbia, had become a sort of depot for the sale of slaves, and that men visited it from distant parts of the United States in order to purchase them.[101]

About this time slaves were in great demand and very high in Mississippi,[102]and probably, also, in the new States of Kentucky and Tennessee.[103]However, it is not to be supposed that the great increase of the slave population in these sections before 1815 was due, to any great extent, to the domestic slave trade. There were five causes which may be assigned for this increase, of which the domestic trade was, probably, among the least, if not the least. No doubt, the most important was the immigration of slave holders with their slaves.[104]This immigration was considerable: the white population of Tennessee and Kentucky nearly trebled between 1790 and 1800, and between 1800 and 1810 it about doubled, and thepopulation of Mississippi more than quadrupled between 1800 and 1810. Slaves, also, increased in as great a ratio.[105]Second, we consider the South Carolina slave trade from 1804 to 1807 inclusive. From a speech of Mr. Smith of South were sold in the Carolinas, but that the most of Carolina in the United States Senate, December 8, 1820, we learn that only a small part of the negroes introduced in consequence of this trade them were bought by the people of the Western and Southwestern States and territories.[106]Third, was the natural increase. Fourth would be the illegal foreign slave trade,[107]and fifth is the domestic trade. It is impossible to more than approximate the relative importance of these factors.

However, it seems very unlikely that the domestic trade was of much consequence before 1815. Whatever impetus it may have received on account of the demand for slaves just prior tothe South Carolina trade, must have been checked by the consequent heavy importation from abroad. For, on account of this, slaves fell in price, as it is said adults, at this time, generally sold in the Southwest at one hundred dollars each.[108]

If the domestic slave trade had assumed any importance, or even if it had been going on at all before 1815, it seems more than likely that it would have been remarked by travellers, many of whom, both English and American, visited the Southwest and other sections of the country during the period in question. But so far as we can find, none of them make any mention of it whatever.[109]The newspapers of the time, also, are silent in regard to the matter. Doubtless the rise and development of the trade was hinderedor delayed by the War of 1812,[110]but almost immediately after the close of the war, it comes into notice and even prominence. In 1816 Paulding in his "Letters from the South" writes of it from personal observation, and also tells of a man who had even thus early made money in the business.[111]

At this time, indeed, conditions were very favorable to a growth of the domestic trade. The general prosperity and the high price of agricultural products, especially cotton and sugar,[112]caused a great demand for slave labor for the new and fertile lands of the South and Southwest. In 1817 and 1818 the buying up of negroes for these markets was fast becoming a regular business, and it was a very common thing to see gangs of them chained and marching toward the South.[113]They were collected from various places by dealers and shipped down the Mississippi River in flat-boats. Fourteen of these loaded with slaves for sale were seen at Natchez at once about this time.[114]

The statement was made that 8,000 slaves were carried into Georgia in 1817 from the Northern slave holding States.[115]It would seem probable that the greater part of these may have been introduced by immigrants. However, the slave trade must have been great, for on December 20, 1817, the Georgia legislature passed a law to prohibit at once the importation of slaves for sale.[116]

Between 1810 and 1820 slaves in the four States of Georgia, Mississippi, Tennessee and Louisiana in round numbers increased from 202,000 to 332,000,[117]and in some of the other States the increase was about as great. During the same time the white population in the States named increased from 419,000 to 645,000.[118]By far the greater part of this increase took place after 1815. To prove this we will take Louisiana as an example. In 1810 she had a population of 76,500,[119]and in 1815 near the close of the year her population, according to Monette, did not exceed 90,000,[120]an increase of only 12,000; but in 1820 it amounted to 154,000, of which more than 73,000 were negro slaves.[121]It appears that the slaves in Louisiana increased only about 2,000 or 2,500 from 1810 to 1815, but between 1815 and 1820 there was an increase of about 37,000.[122]This wonderful increase in population in the West and Southwest is to be accounted for by thefact that after the close of the War of 1812 immigration again set in these directions, and, as most of the immigrants without doubt were from the older Southern States, they carried with them the slaves which they had in their native States.[123]Another source from which this region received slaves at this time was through the operation of the illicit foreign trade. It is probable that 10,000 or 15,000 a year were thus introduced.[124]It therefore seems that up to this time to the domestic trade is due probably only a minor part of the increase of the slave population of this section.

During the twenties, however, if we are to give credit to the statements of travellers, the trade reached very great proportions. Baltimore, Norfolk, Richmond, Washington and other places had already become centres. Agents were placedin these cities to attend to purchase and shipment. "And thousands and tens of thousands," such is the language of an English tourist, were purchased in Virginia and Maryland for sale in Georgia, Louisiana and other States.[125]Blane, another Englishman, who visited the United States about the same time, is more to the point.

"It is computed," he says, "that every year from ten to fifteen thousand slaves are sold from the States of Delaware, Maryland and Virginia and sent to the South."[126]

Basil Hall was informed, in 1827 or 1828, that during certain seasons of the year, "all the roads, steamboats and packets are crowded with troops of negroes on their way to the slave markets of the South.[127]Vessels, indeed, from the selling States were sometimes seen in New Orleans with as many as two hundred negroes aboard."[128]

This transportation of negroes from the borderStates to the South and Southwest from about 1826 to 1832 may be partly accounted for by the probable falling off in the illicit importations[129]and by the fact that cotton and tobacco, which were the staples of some of the border States, were comparatively low in price,[130]making them very unprofitable crops to cultivate in these States. The cotton raised in North Carolina and Virginia decreased almost half during this time.[131]While it appears as if the lower price of cotton merely had the effect in the new States to increase the acreage in order to make up for the deficiency in price. In the new States there was a wonderful increase in production during this period.[132]Slaves, therefore, were of much less productive value in the border States, while in the new States the demand for them was scarcely lessened.

The "New Orleans Mercantile Advertiser," of January 21, 1830, says:

"Arrivals by sea and river, within a few days, have added fearfully to the number of slavesbrought to this market for sale. New Orleans is the complete mart for the slave trade—and the Mississippi is becoming a common highway for the traffic."[133]

In the summer of 1831, New Orleans imported 371 negroes in one week, nearly all of whom were from Virginia.[134]

In the same year, August 1831, an insurrection of slaves, in which a number of white people were murdered, occurred in Southampton County, Virginia.[135]This caused much excitement throughout the slave States. It opened the eyes of the people to the danger of a large slave population. It seemed, for a while, that it would have a very detrimental effect upon the domestic slave trade, for several importing States began to consider the advisability of prohibiting the further introduction of slaves. Two of the largest importing States,[136]indeed, passed such laws: Louisiana, which, in March, 1831, had repealed her lawregulating the importation of slaves[137]in November of the same year, at an extra session of her legislature enacted a law against their importation for sale.[138]And, in January, 1832, Alabama followed suit.[139]

The Virginia Legislature of 1831-2, also took up the question of slavery and with open doors vigorously discussed methods of emancipation, and of getting rid of the negro population. It was recognized that the value of slaves in Virginia depended greatly upon the Southern and Western markets. It was feared that other buying States would follow the lead of Louisiana, thus cutting off the outlet of Virginia's surplus slaves, and while the whites were constantly emigrating, the rapidly increasing black population would tend to become congested in the State, producing a condition of society alarming to contemplate.[140]

But these forebodings were far from ever being realized. Indeed, even before the end ofthe year the conjunction of two causes produced a great demand for slaves and they were soon higher in price than they had been for years. First, planters from the cotton-growing States visited Virginia in great numbers in order to make purchases of slaves, doubtless, thinking they could buy cheaply, as it seemed that on account of the Southampton Insurrection Virginia was determined to get rid of her slaves at all hazards.[141]Second, the most important was the advance in price of cotton. This began, also, in 1832. It continued to rise for several years and by 1836 it had doubled in price,[142]while by 1839 its production, also, had nearly doubled. This increase was due almost wholly to the South and Southwest, Mississippi alone producing nearly one-fourth of the entire crop.[143]

As a consequence we should expect to note a corresponding briskness in the slave trade. Such, indeed, was the case. We have no reason to think that more slaves were ever exported to the Southfrom the Northern slave States during any equal period of time than there were from 1832 to 1836 inclusive. Of these 1836 is easily the banner year.

In 1832 it was estimated by Prof. Dew that Virginia annually exported for sale to other States 6,000 slaves.[144]During the thirties, or even before the slave trade was carried on between the selling and buying States with about the same regularity as the exchanges of cotton, flour, sugar and rice.[145]Vessels engaged in the business advertised their accommodations. One trader, John Armfield, had three which were scheduled to leave Alexandria for New Orleans, alternately, the first and fifteenth of each month during the shipping season.[146]

That the trade had become extensive is evidenced by the newspapers. Up to 1820 it was very uncommon to find a trader's advertisementin a newspaper, but even before 1830 such advertisements had become very plentiful. One could hardly pick up a paper published in the selling States, especially those of the Eastern Shore of Maryland and Eastern Virginia, without finding one or more. These advertisements often continued from month to month and from year to year.[147]

An example or two may be interesting:

"Cash for Negroes:—I wish to purchase 600 or 700 negroes for the New Orleans market, and will give more than any purchaser that is now or hereafter may come into the market." Richard C. Woolfolk.[148]

"Cash for Negroes:—We will give cash for 200 negroes between the ages of 15 and 25 years old of both sexes. Those having that kind of property for sale will find it to their interest to give us a call." Finnall and Freeman.[149]

The number of slaves currently estimated to have been transported to the South and Southwest during 1835 and 1836 almost staggers belief. The "Maryville (Tenn.) Intelligencer" made the statement in 1836 that in 1835 60,000 slaves passed through a Western town on their way to the Southern market.[150]Also, in 1836, the "Virginia (Wheeling) Times" says, intelligent men estimated the number of slaves exported from Virginia during the preceding twelve months as 120,000 of whom about two-thirds were carried there by their masters, leaving 40,000 to have been sold.[151]The "Quarterly Anti-Slavery Magazine," July 1837, gives the "Natchez Courier" as authority for the estimate that during 1836, 250,000 slaves were transported to Alabama, Mississippi, Louisiana and Arkansas from the older slave States.[152]A committee, in 1837, appointed by the citizens of Mobile to enquire into the cause of the prevalent financial stringency stated in their report that for the preceding fouryears Alabama had annually purchased from other States $10,000,000 worth of slave property.[153]

When the panic of 1837 came upon Mississippi, it was thought, it seems, to have been caused through the amount of money sent out of the State in the purchase of slaves, and Governor Lynch, upon the petition of the people, convened the legislature in extra session, and in his message to it says:

"The question which presents itself and which I submit for your deliberation [is]—whether the passage of an act prohibiting the introduction of slaves into this State as merchandise may not have a salutary effect in checking the drain of capital annually made upon us by the sale of this description of property."[154]

The panic of 1837 caused a falling off in the domestic slave trade, and the low price of cotton which continued until 1846[155]hindered its revival. The falling off in the trade is shown by the factthat the per cent. of increase in the slave population of the cotton States was scarcely half as great between 1840 and 1850 as during the previous decade.[156]The slave trade, however, seems to have become brisker in 1843, for while only 2,000 slaves are said to have been sold in Washington in 1842, in 1843, 5,000 were sold there.[157]It does not necessarily follow, however, that all these were sent South. The increased number of sales was caused by two things: the decline in the price of tobacco,[158]and the renewed activity in the sugar industry incident upon a new duty on sugar.[159]This gave rise to a demand for slave labor upon the sugar plantations of the South, but it was a very limited demand. During this period the decline in the value of slaves was great in some States,[160]and it appears very probable there was a general depreciation in value. However, before 1850 three important things had happened, each of which had an effect upon theslave trade. First, the admission of Texas, December, 1845; second, the gradual increase in the price of cotton after 1845; third, the discovery of gold in California. The first opened a large cotton country to development and the required slave labor could be legally supplied only from the United States. The rise in cotton which continued almost uniformly until 1860[161]caused a new impetus to be given to its culture, and the discovery of gold in California infused new life into all the channels of trade.

In a few years, indeed, after 1845, the demand for slaves seems to have been greater than the supply. A writer in the "Richmond Examiner," in 1849, says:

"It being a well ascertained fact that Virginia and Maryland will not be able to supply the great demand for negroes which will be wanted in the South this fall and next spring, we would advise all who are compelled to dispose of them in this market to defer selling until the sales of the present crop of cotton can be realized as the price then must be very high owing to two reasons:First, the ravages of the cholera, and secondly, the high price of cotton."[162]

Indeed, during the fifteen years prior to 1860 the demand for slaves became so great that it caused an increase of one hundred per cent. in their price.[163]However, there was not a great increase in the domestic slave trade. According to a custom house report there were shipped from Baltimore in a little less than two years, in 1851 and 1852 only 1,033 negroes.[164]This is certainly not a large showing though it is probable a great many were sent overland to the South from this place during the same time.

In a speech before the Southern Convention at Savannah in 1856, Mr. Scott, of Virginia, made the statement that not more than half the lands in the sugar and cotton-growing States had been reduced to cultivation, and that all the valuable slaves in Virginia, Maryland, Kentucky and Missouri would be required to develop them.[165]But at this time the prosperity of the latter militatedagainst the transfer of labor to the cotton-growing States. Probably the conditions in the border States is best described by quoting from a writer in "De Bow's Review" in 1857:

"The difficulty," he says, "of procuring slaves at reasonable rates, has already been severely felt by the cotton planters, and this difficulty is constantly increasing. The production of rice, tobacco, wheat, Indian corn, etc., with stock raising, in those States affords nearly as profitable employment for slave labor as cotton planting in other States. They have not, as is generally supposed, a redundancy of slave labor, nor are they likely to have so long as their present prosperity continues.

"The recent full development of the rich agricultural and mineral resources of these States, indeed, by an immense demand for their staple productions, have not only given profitable employment to slave labor, but has improved the pecuniary condition of the slave owner and placed him above the necessity of parting with his slave property."[166]

Even Olmsted, inadvertently, no doubt, gives evidence of the prosperity of Virginia, a little before this time, when he says that in the tobacco factories of Richmond and Petersburg slaves were in great demand and received a hundred and fifty to two hundred dollars and expenses a year.[167]In North Carolina, also, good hands would bring about the same wages.[168]

Though the labor market in the border States was greater than the natural increase of the negro, yet it was hardly to be compared to the Southern demand. As a consequence, when debt, or necessity, or other reason, compelled the sale of slaves, they were often bought by traders and exported.[169]The statement was made by Mr. Jones, of Georgia, in the Savannah Convention, 1856, that negroes were even then worth from $1,000 to $1,500 each, and that there were ten purchasers to one seller.[170]

Indeed, so great was the demand for slaves at this time that the advisability of reopening the African slave trade became one of the principal topics of discussion in Southern Agricultural and Commercial Conventions.[171]In fact, the Vicksburg Convention, 1859, passed a resolution in favor of reopening the African trade.[172]

The New Orleans newspapers during all this period give evidence of the domestic trade. It was very common during the shipping season to see advertisements to the effect that the subscriber, a negro trader, had received, or had just arrived from Virginia, Maryland, the Carolinas or elsewhere, with a large lot of negroes which were offered for sale. Usually the number would be given as fifty, seventy-five, or even a hundred. This would be qualified by the statement that they would be constantly receiving fresh lots. The same advertisement would continue in the same paper for months and even years. Sometimes half a dozen of these could be found in a singleissue of a paper. It would be impossible even to approximate from this source the number sold during any given time, for it is likely the number offered for sale bore but little relation to the actual number sold. The States of Maryland, Virginia and the Carolinas were most conspicuous in these advertisements.[173]

Writers on the subject seem to be pretty well agreed that during this period, or during the fifties, about 25,000 slaves were annually sold South from the Northern slave States.[174]

It is interesting to notice in this connection what the Census Reports have to show. But in reading it should be remembered that no account is taken of the sale of slaves except as they took place between the buying and selling States. So the sale of slaves between Virginia and Marylandare not indicated nor those between Mississippi and Alabama.

The slave population of Alabama, Arkansas, Georgia, Louisiana, Mississippi, South Carolina, Tennessee and Missouri in 1820 was in round numbers 644,000, in 1830 997,000 being an increase of 353,000. The slave population in the selling States of Virginia, Maryland, Delaware, North Carolina, Kentucky and the District of Columbia at the same periods[175]was 873,000 and 993,000 respectively, being an increase in these States of 120,000. Total increase of slaves in both sections during the decade, 473,000, from which we deduct 50,000 due to the illicit foreign traffic,[176]leaving 423,000 from natural increase or about 28 per cent. Had the selling States increased at this ratio, instead of 120,000 their increase would have been 244,000. This would seem to indicate that at least 12,400 annually were carried South during this decade. However, only the smaller part of these, and those of the following decade as well, were transportedthrough the operation of the domestic slave trade. Mr. P.A. Morse, of Louisiana, writing in 1857, says that the augmentation of slaves within the cotton States was caused mostly by the migration of slave owners.[177]The "Virginia Times," in 1836, says of the number of slaves exported during the preceding twelve months "not more than one-third have been sold, the others having been carried by their owners who have removed."[178]We conclude from these and other sources[179]that at least three-fifths of the removals of slaves from the border slave States to those farther South from 1820 to 1850 were due to emigration.[180]Thus it is shown that probably 5,000[181]slaves were annually exported by the selling States from 1820 to 1830 by means of the domestic trade.

In the next decade adding Florida to the buying State and transferring South Carolina[182]and Missouri[183]to the selling list, we find that in 1830 and in 1840 the buying States had 672,000 and 1,127,000 respectively, being an increase of 455,000; while for the same periods the selling States had 1,333,000 and 1,361,000, being an increase of 28,000. The whole increase, therefore, was 483,000,[184]deducting 40,000 due to illicit foreign trade,[185]we have 443,000 or about 22 per cent. as the natural increase. Had the selling States increased at same rate it would have been 293,000 for the decade. Deducting 28,000 we find that 265,000 can be accounted for only as having been exported. Deducting three-fifths for emigration we have, removing 106,000 for the domestic traffic, an average of 10,600 per year.

By 1850, the buying States had another increase of 478,000 and the selling States 180,000. Total increase from 1840 to 1850, 658,000.[186]Deducting 50,000 illicitly imported,[187]we have 606,000 or about 24 per cent. total increase. Accordingly the selling States should have a natural increase of 326,000. Deducting the actual numberwe have left 146,000, which must have been transported. Deducting three-fifths on account of emigration, there would remain about 58,000 or nearly 6,000 per year for the domestic trade.

Adding Texas to the buying States in 1850, they then have 1,663,000, and in 1860 2,296,000, or an increase of 633,000 during the decade. And the selling States 1,541,000 and 1,657,000 respectively, being an increase of 116,000. Total increase 749,000.[188]Deducting 70,000 which were brought in by illicit trade[189]we have a remainder of 679,000 or 21 per cent. natural increase. From natural increase selling States should have had 207,000 more than the actual. Deducting three-fifths on account of emigration leaves a little more than 8,000 per year sold South annually for these ten years.

It is very probable that the emigration to the cotton States fell off during the fifties owing to the great prosperity in the border States, and it might be fair to reduce the number estimated to have been carried South by emigration to one-third or one-half, which would leave ten or twelve thousand per year for the domestic slave trade.

We feel quite confident that this statistical review of the domestic slave trade, based as it is upon the Census Reports, gives a truer idea of the actual amount of the trade between the selling and the buying States than could be got from any other sources.
