Lord Rockingham's ministry, which succeeded Mr.Grenville's, had, as is well known, but a brief existence, and was replaced by the cabinet so whimsically composed by Mr.Pitt, who reserved to himself the office of Privy Seal, with the Earldom of Chatham; the Duke of Grafton being the nominal head of the Treasury, but the direction of affairs being wholly in the hands of the new Earl, till the failure of his health compelled his temporary retirement from public life.

Lord Chatham was brother-in-law to Mr.Grenville, to whom in the occasional arrogance and arbitrariness of his disposition he bore some resemblance; and one of the earliest acts of his administration, when coupled with the language which he held on the subject in the House of Lords, displayed that side of his character in a very conspicuous light.
The summer of 1766 had been unusually wet and cold, both at home and abroad, and the harvest had, in consequence, been so deficient as to cause a very general apprehension of scarcity, while rumors were spread that the high prices which the shortness of the crops could not fail to produce were artificially raised by the selfish covetousness of some of the principal corn-dealers, who were buying up all the grain which came into the market, and storing it, with the object of making an exorbitant profit out of the necessities of the consumer, not only at home but abroad.

The poorer classes, seeing themselves, as they believed, threatened with famine, rose in riotous crowds, in some places attacking the barns in which the corn was stored, and threatening destruction to both the storehouses and the owners.

The ministry first tried to repress the discontent by the issue of a proclamation against "forestallers and regraters," framed in the language and spirit of the Middle Ages; and, when that proved ineffectual to restore confidence, they issued an Order in Council absolutely prohibiting the exportation of any kind of grain, and authorizing the detention of any vessels lying in any British harbor which might be loaded with such a cargo.

Our annals furnished no instance of such an embargo having been laid on any article of commerce in time of peace; but the crisis was difficult, the danger to the tranquillity of the kingdom was great and undeniable, the necessity for instant action seemed urgent, and probably few would have been inclined to cavil at Lord Chatham's assertion, that the embargo "was an act of power which, during the recess of Parliament, was justifiable on the ground of necessity," had the ministry at once called Parliament together to sanction the measure by an act of indemnity.
