committee of management of the Forth and Clyde canal, and the leading manager of various other public bodies. A genius for business on a large scale was conspicuous in all his undertakings. In 1785, he repaired to London to obtain legislative relief for the cotton trade, then in a languishing condition, and for some years afterwards he devoted a large portion of his time to similar objects. In 1788, he visited Ostend, then a depot for East India goods, to ascertain how far similar British manufactures could enter into competition with the imports of the Flemings; and it was owing to his exertions that our muslins, then an infant manufacture, became so extensively known throughout the continent Connected with this subject he published three pamphlets, which tended to make his efforts known to the British merchants. In the same year, Mr Colquhoun kid the plan of a general hall in London for the sale of cottons, which, however, was rendered of little effect by the breaking out of the war with France. On this subject he also published a pamphlet. In the month of November 1789, he settled with his family in London, and soon after began to project those improvements in the London police and magistracy, by which he earned the principal part of his fame. The police of London was at this time in a state of shameful inefficiency,
while the magistrates, excepting in the city itself, were a set of low mercenary individuals, known by the justly opprobrious title of "trading justices." On this subject Mr Colquhoun composed several popular treatises, and in 1792, when seven public offices were established, with three justices to each, he was appointed to one of them, through the influence of his friend Mr Henry Dundas, afterwards viscount Melville. His exertions as a magistrate were of a nature truly useful; and he published the result of his experience in 1796, under the title of "A Treatise on the Police of the Metropolis, explaining the various Crimes and Misdemeanours which at present are felt as a Pressure on the Community, and suggesting Remedies." This work earned a merited reputation, and went through a large annual reprint for the five succeeding years. It obtained the praise of the select committee of finance, and particular marks of approbation from the duke of Portland, then secretary of state for the home department. He was, in consequence of this work, appointed agent in Great Britain for the colony of the Virgin Isles. In 1800, appeared his treatise on the Police of the River Thames, a work certainly demanded in no small degree
by the circumstances. Though it may hereafter appear almost incredible, it is nevertheless true, that the shipping of London, previous to this period, was totally unprotected from the vast hordes of thieves which always exist in a large city. While property on the banks of the river was so far protected, that which floated on the river itself had no protection whatever. Accordingly, a generation of thieves called mudlarks, prowled constantly about the vessels, and made prey annually of property to a vast amount. Not only did the cargoes suffer, but even sails, anchors, and other such bulky articles, were abstracted by these daring depredator. For many years this had been felt as a grievous hardship, but it is amazing how long an evil may be tolerated for which no remedy has been provided by the necessities of our ancestors. It Mas looked upon as a matter of course, a mischief incident to the situation of things ; and as each individual only suffered his share of the immense amount of loss, there had been no general effort at a reformation. Mr Colquhoun's work, however, effectually
roused public attention to the subject, and an effective river police was immediately instituted, by which the shipping has been ever since fully protected. For his services on this occasion, the West India merchants presented him with the
sum of five hundred pounds.
Although Mr Colquhoun bore externally a somewhat pompous and domineering aspect, and was certainly a zealous advocate for keeping the people in due
