The 1850s saw the beginning of the great international expositions, and Logan was a talented promoter of Canada's mineral resources abroad, starting with the Exhibition of the Industry of All Nations, the 1851 world fair at the Crystal Palace in London, England. A second similar opportunity came in 1855 with the Universal Exposition in Paris. Canada's participation in these high-profile events stimulated international interest in Canadian minerals and brought personal honours to Logan. Logan exhibited Charles and Henry's asphalt, where it won an honorable mention. He received the French Cross of the Legion of Honour from Napoleon III in 1855, and his greatest honour, his knighthood bestowed by Queen Victoria at Windsor Castle in 1856. That same year he was awarded the Wollaston Medal, the highest award of the Geological Society of London. Throughout his career, Logan was to receive dozens of prestigious awards.
