John Horne Stevenson, Dictionary of National Biography (1901)
“ On coming of age Bute became the owner of estates, not only in Scotland but in Wales—at Cardiff and its neighbourhood. Cardiff, as one of the principal ports of the United Kingdom, and the largest coal-exporting port in the world, practically owes its existence to the foresight and expenditure of the marquis's father. The Bute docks, which his father began, he carried to completion with the same courage and intelligence; they now cover over 160 acres, and cost about 4,000,000l. The population of the city, which in 1801 was two thousand, is now over one hundred and fifty thousand. ”
