A pigeon named Sappho, whom they had previously labeled as "undependable", suddenly arrives with an urgent message from Titty, "FIRE HELP QUICK". Captain Flint rings Colonel Jolys, who musters his volunteer fire fighters, and they all rush to help save the Topps. After the fire on the fells is extinguished, Squashy Hat is revealed to be Captain Flint's friend Timothy, who has been too shy to introduce himself to the children. Captain Flint is pleased to find copper, as he had talked with Timothy above Pernambuco in South America about new ways of prospecting for copper on the fells, and planned to look for copper using new methods not known to the "old miners". Indeed, when the search for gold in South America was unsuccessful, their second plan was to look for the copper in the Topps.
