Some other well-contested actions took place at sea, and the English, upon the whole, confirmed their naval supremacy. Owing, however, to a failure of the supplies, the king was obliged to lay up his best vessels in ordinary, and to send only an inferior force to sea. The Dutch took advantage of this occurrence to send a fleet up the Thames (June 10, 1667), which, meeting with no adequate resistance, threatened to lay the capital in ruins and destroy its shipping. Fortunately, the Dutch admiral did not think it expedient to make this attempt, but retired with the ebb of the tide, after having sunk and burnt nearly twenty vessels, and done much other damage. The king, finding himself rather impoverished than enriched by the war, soon after concluded a peace. PLAGUE AND FIRE OF LONDON――PERSECUTION IN SCOTLAND. In the meantime two extraordinary calamities had befallen the metropolis. In the summer of 1665, London was visited by a plague, which swept off about 100,000 people, and did not experience any abatement till the approach of cold weather. On this occasion the city presented a wide and heartrending scene of misery and desolation. Rows of houses stood tenantless, and open to the winds; the chief thoroughfares were overgrown with grass. The few individuals who ventured abroad, walked in the middle of the streets, and when they met, declined on opposite sides to avoid the contact of each other. At one moment were heard the ravings of delirium, or the wail of sorrow, from the infected dwelling; at another the merry song or careless laugh from the tavern, where men were seeking to drown in debauchery all sense of their awful situation. Since 1665, the plague has not again occurred in London, or in any other part of the kingdom.
