Hokkaido represented the Japanese frontier at that time and with so much work to be done in colonizing the island, Kuroda welcomed and frequently implemented Clark's advice. Clark submitted recommendations to the governor on such diverse subjects as converting migratory fisherman into permanent colonists and establishing a textiles industry. In fact, Clark himself was taken aback by the apparent scope of his influence on colonial affairs, writing to his wife, "Governor Kuroda consults me constantly and always follows my advice." He later wrote, "I tremble to think how much confidence is reposed in me and what responsibilities I am daily assuming."
