“Well, Gresham Street is named after the man who built that Exchange,—Sir Thomas Gresham. And the grasshopper in Lombard Street is the Gresham crest. London in this reign of Elizabeth has become very rich and prosperous. Well, its riches and its prosperity have been so greatly increased by Sir Thomas Gresham, that I must tell you something about him. He is a great merchant who in this year, 1590, has a goldsmith’s shop in Lombard Street at the sign of the Grasshopper. For though he has been knighted, and now has a great house in Bishopsgate Street, he still keeps his shop. When he was a younger man, he went to Antwerp, where there was a fine building for the use of the merchants in that city. Now in London, there was no convenient place for the use of merchants who wanted to discuss business, so on his return, Thomas Gresham built that Exchange you see before you, and made it as much as possible like the Exchange he had seen in Antwerp. That, you see, accounts for its foreign appearance. He then presented the mansion to the City of London, and invited Queen Elizabeth to open it, and it was _she_ who called it The _Royal_ Exchange—(a name our present Exchange still keeps). Well, at the time at which we’ve arrived now, it has been open about twenty years, and has been so useful for commerce, that the trade of London has enormously increased. There are, of course, other reasons for the present wealth of the City, some of which we shall find out later. But that Royal Exchange has greatly helped its prosperity.” “It’s quite different from the one we have now,” said Betty, “and it looks as though it ought to last for ages. Why isn’t it standing in _our_ day?” “Because it was burnt down in the Great Fire, like so many other beautiful and interesting things. Then another one was built, and that also was burnt. So there have been _two_ Royal Exchanges on the same spot as that on which the third—our present one—stands.” “Sir Thomas Gresham, in this reign, is rather like what Dick Whittington was in the reign of Richard the Second, I suppose?” Betty remarked. “Dick Whittington was a great merchant too, who did a lot of good for London.” “Yes, London has been very fortunate in having generous merchants.” “Now let us go back to London Bridge, and see if we can find other reasons besides the Exchange for the increase of wealth and luxury in this city.” As Betty followed her, she looked back at Sir Thomas Gresham’s quaint building with its sloping roof, its high middle tower, and the gilded grasshoppers on its pinnacles. It was a very different place indeed from the one she had visited this very morning with all the roar and bustle of modern London round about it, but its _purpose_ was the same. For now, as then, the Royal Exchange is the centre of London’s enormous trade. When they reached the river again, Betty noticed at once how much more crowded the shipping had become than it was in the fourteenth century.
