All this prosperity grew in spite of the wars which we carried on during the whole of the last century. These wars, though they covered the Channel and the Bay of Biscay with privateers, had little effect to stay the increase of London trade. And as the merchants lived within the City, in sight of each other, their wealth was observed and known by all. At the present day, when London from nightfall till morning is a dead city, no one knows the wealth of the merchants and it is only by considering the extent of the suburbs that one can understand the enormous wealth possessed by those men who come up by train every day and without ostentation walk among their clerks to their offices in the City. A hundred and fifty years ago, one saw the rich men: sat in church with them: sat at dinner with them on Company feast days: knew them. The visible presence of so much wealth helped to make London great and proud. It would be interesting, if it were possible, to discover how many families now noble or gentle--county families--derive their origin or their wealth from the City merchants of the last century. In one thing there is a great change. Till the middle of the seventeenth century it was customary for the rank of trade to be recruited--in London, at least--from the younger sons. This fashion was now changed. The continual wars gave the younger sons another career: they entered the army and the navy. Hence arose the contempt for trade which existed in the country for about a hundred and fifty years. It is now fast dying out, but it is not yet dead. Younger sons are now going into the City again.
