One of the most gallant exploits of this period was performed by Captain Best, who sailed in command of a fleet sent out by the East India Company. After remaining for some time at Surat, he caught sight of a vast fleet of Portuguese, numbering no less than 240 vessels. Having beaten off a number of them that attacked him, he continued his course. They, however, having repaired damages, the whole fleet came in search of him. As they bore down under a cloud of sail, threatening his destruction, he was advised by one of the Sultan's principal officers to fly. Best replied that he would advise that to the Portuguese, and, weighing anchor, stood out to meet the enemy. The shore was crowded with natives eager to witness the engagement. It ended, after four hours, as the other had done. The Portuguese, after receiving immense damage, sailed away as fast as they could, and Captain Best returned and anchored in the harbour, amid the shouts of the people. The account of the engagement was everywhere told among the natives, and the courage of the English magnified to the highest. After touching at Achin, and renewing his friendship with the people, in the succeeding year, he arrived in England, rich in his lading, more in honour. In the year 1613 the Muscovy Company sent out seven stout ships to catch whales. They were followed by several Dutch, Flemish, and French ships, and half-a-dozen English interlopers. The Company's ships gathering into a body, ordered the others, in the name of the King of England, to depart from the coast, the fishery of which he had appropriated to his own subjects. The Dutch sending a taunting answer, the English replied with their cannon, compelling their rivals to take their departure, and the English private ships to fish for them. With this help, they made a good return. In 1614 the celebrated pirate Sir Andrew Barton, with two ships, laid the coasts of England and Scotland under contribution. Two ships of war, under the command of Sir William Monson and Sir Francis Howard, were sent out to effect their capture. One of them was taken off Sinclair Castle, the seat of the Earl of Caithness. Sir Andrew for long managed to keep at a distance from his pursuers, having friends in various places, especially in Ireland, who gave him assistance. Among others was a certain Mr Cormat, who treacherously betrayed the Scotch pirate into the hands of Sir William Monson. His ship was captured, and he, with two or three of his officers, executed. Considerable progress at this period was made in the science of navigation. In the year 1624 Mr Gunter, professor of astronomy at Gresham College, Cambridge, published his scale of logarithms, sines, etcetera, and invented the scale which has since gone by his name.
