The spring of 1720 was a period of remarkable national prosperity. But "the grand money schemes projected of late," which appeared to the Jacobite Atterbury and others calculated to cement the royal peace and strengthen the foundation of the Government and nation, were destined to produce a very different effect. For the South Sea Bubble was about to burst. In 1711, Harley, being at his wits' end to maintain the public credit, established a fund to provide for the National Debt, which amounted to ten millions of pounds. To defray the interest he made permanent the duties on wine, vinegar, and tobacco, etc. To induce the purchase of the Government stock, he gave to the shareholders the exclusive privilege of trading to the Spanish settlements in South America, and procured them an Act of Parliament and a royal charter, under the name of the South Sea Company. The idea, hollow and groundless as it was, seized on the imagination of the most staid and experienced traders. All the dreams of boundless gold which haunted the heads of the followers of Drake and Raleigh were revived. The mania spread through the nation, and was industriously encouraged by the partisans of Harley. But this stupendous dream of wealth was based on the promises of Ministers, who at the Peace of Utrecht were to secure from the Government of Spain this right to trade to its colonies. The right was never granted by that haughty and jealous Power, further than for the settlement of some few factories, and the sending of one small ship annually of less than five hundred tons. This, and the Assiento, or privilege of supplying those colonies with African slaves, were the sole advantages obtained, and these were soon disturbed by the war with Spain, which broke out under Alberoni. The South Sea Company, however, from its general resources, remained a flourishing corporation, and was deemed the rival of the Bank of England.

It was at the close of 1719, when George I. returned from Hanover, that this Company proposed to Ministers to consolidate all the funds into one. It was strange that both Ministers and merchants could be deluded by the hope of enriching themselves by a share of the trade with the Spanish South American provinces, when Spain herself, in full enjoyment of them, was sunk into indigence and weakness, and presented the most determined resistance to the unfettered intercourse of any other nation with them. Yet Sir John Blunt, a leading director of the South Sea Company, persuaded the Ministers that by granting the Company power to deal with the public funds, and especially to buy up the unredeemable annuities which had been granted in the two preceding reigns, chiefly on terms of ninety-nine years, and which now amounted to about eight hundred thousand pounds a year, they could, in twenty-six years, pay off the entire National Debt. But, to enable them to do this, they must be empowered to reduce all the different public securities to one aggregate fund in their hands, to convert both redeemable and unredeemable debts into stock by such arrangements as they could make with the holders, and to have certain commercial privileges vested in them. Ministers accepted the proposals with great alacrity. Aislabie introduced the scheme to Parliament in the month of February, 1720, declaring that, if it was accepted by the House, the prosperity of the nation would be amazingly enhanced, and all its debts liquidated in a very few years. Craggs seconded the proposal in most sanguine terms, expressing his conviction that every member of the House must be ready to adopt so advantageous an offer. Ministers had already closed with the proposals of the Company, and they were themselves greatly disconcerted by the suggestion of Mr. Thomas Brodrick, the member for Stockbridge, who expressed his entire accordance with Ministers, but thought that the nation should endeavour to obtain the best terms for itself by opening the competition to every other company or association of men as well as that in question. Ministers were confounded by this proposal, and Aislabie endeavoured to get out of it by declaring that to do this would be like putting the nation up to auction, and that such things should be done with spirit. But Jekyll interposed, saying it was this spirit which had ruined the nation, and it was now requisite to consider seriously what was best for the public. A violent debate ensued, in which Walpole eloquently recommended open competition, and was sharply replied to by Lechmere. The question was carried in favour of competition; and then the Bank of England, which before had coolly declined to enter into the proposals, suddenly appeared in a new temper, and made liberal offers for the privilege of thus farming the public debts. But the South Sea Company was not to be outdone; it offered seven millions and a half, and the Bank gave way in despair.

Walpole, however, continued to oppose the South Sea Bill in the Commons, declaring that the terms were too extravagant ever to be fulfilled; that the experiment could result in nothing but a fearful increase of the costs of stockjobbing, and final confusion and ruin. He insisted that, before the proposals of the Company were accepted, the rise of their stock should be limited, and every means taken to prevent the fever of infatuation that would ensue from the promise of dividends out of funds which could never be realised. He proposed for this purpose the introduction of a clause fixing the number of years' purchase to be granted to the annuitants of the South Sea Company; but to this it was objected that it was the interest of the Company to take up the annuities; and, as the annuitants had the power of coming in or not, as they pleased, the Company would, of course, offer advantageous terms, and, therefore, the whole affair might be safely left to private adjustment. Aislabie added that the South Sea Company would not submit to be controlled in an undertaking they were to pay so dear for. The Bill passed both Houses.

The South Sea Company had immediately on the passing of the Bill proposed a subscription of one million, and this was so eagerly seized on that, instead of one, two millions were subscribed. To stimulate this already too feverish spirit in the public, the Company adopted the most false and unjustifiable means. They had eight millions and a half to pay over to Government as a douceur for granting them the management of the Funds; and, therefore, to bring this in rapidly, they propagated the most lying rumours. It was industriously circulated that Lord Stanhope had received overtures at Paris to exchange Gibraltar and Port Mahon for invaluable gold lands in Peru! The South Sea trade was vaunted as a source of boundless wealth in itself. In August the stock had risen from the one hundred and thirty of the last winter to one thousand! Men sold houses and land to become shareholders; merchants of eminence neglected their affairs and crippled their resources to reap imaginary profits. The Company flattered the delusion to the utmost. They opened a third, and even a fourth subscription, larger than the former, and passed a resolution that from next Christmas their yearly dividend should not be less than fifty per cent.! In labouring to increase the public delusion they seem to have caught the contagion themselves, for they began to act, not like men who were blowing a bubble which they knew must speedily burst, but like persons who had mounted permanently into the very highest seat of prosperous power. They assumed the most arrogant and overbearing manner, even towards men of the highest station and influence. "We have made them kings," said a member of Parliament, "and they deal with everybody as such."

The spirit of gambling thus set going by Government itself soon surpassed all bounds, and burst forth in a thousand shapes. It was well known that the king, his mistresses, his courtiers, his son and heir apparent, were all dabbling busily in the muddy waters of this huge pool of trickery and corruption. A thousand other schemes were invented and made public to draw in fresh gudgeons, and the Prince of Wales allowed his name to stand as governor of a Welsh Copper Company. All ranks and classes rushed to Change Alley—dukes, lords, country squires, bishops, clergy (both Established and Dissenting), were mixed up with stockjobbers and brokers in eager traffic. Ladies of all ranks mingled in the throng, struggling through the press and straining their voices to be heard amid the hubbub. There and all over the kingdom were advertised and hawked about the following and other schemes:—Wrecks to be fished for on the Irish coast; plans for making of oil from sunflower seeds; for extracting of silver from lead; for the transmuting of quicksilver into a malleable and fine metal; for importing a number of large jackasses from Spain; for a wheel for perpetual motion; and, finally, for an undertaking which shall in due time be revealed!

The South Sea Company, with a folly of which extreme greed only is capable, endeavoured to put down these rival schemes and obtained an order from the Lords Justices and writs of scire facias against several of these new bubbles. It was like raising a wind to blow away the bubbles, forgetting that their own was a bubble too, and would go with them. The moment that the people began to distrust one they distrusted all. The panic became as great as the mania had been. The South Sea stock dropped in less than a month from one thousand to below six hundred. There was a simultaneous rush to sell out, and the shares must have sunk instantly to nil but for the gigantic exertions of the Company to raise money and buy in. The relief, however, was but temporary. The bankers and pawnbrokers who had advanced money on scrip broke and fled; merchants, goldsmiths, and speculators rushed away after them. Walpole was summoned in haste from Haughton to devise some means of staying the panic. He endeavoured to get the Bank of England to circulate three millions of South Sea bonds for a year; but the Bank, seeing that the case was desperate, declined it. This was decisive. The rage and despair of the swarming dupes were indescribable. They heaped execrations not only on the South Sea Company, but on Ministers, the king, his mistresses, and the Royal Family, who had all been deep in the affair, and who had taken good care of themselves. George landed at Margate on the 9th of November, soon after which the South Sea stock fell to one hundred and thirty-five. On the 8th of December Parliament met, and promptly began to investigate the scandal.

In the House of Lords on the 24th of January, 1721, five directors who had been called before them were arrested and their papers seized. By what had been drawn from them, it appeared that large sums had been given to people in high places to procure the passing of the South Sea Bill. Lord Stanhope rose and expressed his indignation at such practices, and moved that any transfer of stock for the use of any person in the Administration without a proper consideration was a notorious and dangerous corruption. The motion was seconded by Lord Townshend, and carried unanimously. The examination being continued on the 4th of February, Sir John Blunt refused to answer their lordships, on the plea that he had already given his evidence before the Secret Committee. A vehement debate arose out of this difficulty, during which the Duke of Wharton, a most profligate young nobleman, and president of the Hell-fire Club, made a fierce attack on Stanhope, accused him of fomenting the dissensions between the king and his son, and compared him to Sejanus, who had sown animosities in the family of Tiberius, and rendered his reign hateful to the Romans. Stanhope, in replying to this philippic, was so transported by his rage, that the blood gushed from his nostrils. He was carried from the House, and soon afterwards expired.

Lord Townshend succeeded Stanhope as Secretary of State. Aislabie, who had been deep in the iniquities of the South Sea affair, was compelled to resign his post as Chancellor of the Exchequer, to which Walpole succeeded. Meanwhile the Secret Committee appointed by the Commons continued its labours indefatigably. They sat nearly every day from nine in the morning till eleven at night, and on the 16th of February, 1721, they presented their first report to the House. This revealed a vast amount of Ministerial corruption.

On the very day that this report was being read in the House died one of the accused, James Craggs, Secretary of State. His complaint was smallpox; but the state of mind induced by this exposure is supposed to have rendered the malady fatal. His father, who was Postmaster-General, was so shamefully involved in the same dishonest proceedings, that he took poison.

Charles Stanhope, though clearly guilty, escaped, after examination in the House, by a majority of three, out of respect for the memory of his deceased relative, the upright Lord Stanhope. Aislabie's case came next, and was so palpably bad that he was committed to the Tower and expelled the House, amid the ringing of bells, bonfires, and other signs of rejoicing in the City of London. The bulk of his property, moreover, was seized. This was some compensation to the public, which had murmured loudly at the acquittal of Stanhope. Sunderland's case was the next, and he escaped by the evidence against him being chiefly second-hand. He was acquitted by a majority of two hundred and thirty-three against one hundred and seventy-two. As to the king's mistresses, their sins were passed over out of a too conceding loyalty; but no favour was shown to the directors, though some of them were found to be much poorer when the scheme broke up than they were when it began. Amongst them was Mr. Gibbon, the grandfather of the historian, who afterwards exposed the injustice of many of these proceedings, though at the time they were considered as only too merited. The directors were disabled from ever again holding any place, or sitting in Parliament; and their estates, amounting to upwards of two millions, were confiscated for the relief of the sufferers by the scheme.
