lived on the island. Jonathan, claimed to be the world's oldest tortoise, is thought to have arrived on the island in 1882. An outbreak of measles in 1886 resulted in 113 cases and 8 deaths. Jamestown was lighted for the first time in 1888, the initial cost being borne by the inhabitants. Dinuzulu kaCetshwayo, son of the Zulu king Cetshwayo, was exiled at St Helena between 1890 and 1897. Diphtheria broke out in 1887 and also in 1893 which, with an additional outbreak of whooping cough, led to the death of 31 children under 10. In 1890 a great fall of rock killed nine people in Jamestown, a fountain being erected in Main Street in their memory. A census in 1891 showed 4,116 inhabitants lived on the island. A submarine cable en route to Britain from Cape Town was landed in November 1899 and extended to Ascension by December and was operated by the Eastern Telegraph Company. For the next two years over six thousand Boer prisoners were imprisoned at Deadwood and Broadbottom. The population reached its all-time record of 9,850 in 1901. Although a number of prisoners died, being buried at Knollcombes, the islanders and Boers developed a relationship of mutual respect and trust, a few Boers choosing to remain on the island when the war ended in 1902. A severe outbreak of influenza in 1900 led to the death of 3.3% of the population, although it affected neither the Boer prisoners nor the troops guarding them. An outbreak of whooping cough in 1903 infected most children on the island, although only one died as a result. The departure of the Boers and later removal of the remaining garrison in 1906 (with the disbandment of the St Helena Volunteers, this was the first time the island was left without a garrison) both impacted on the island economy, which was only slightly offset by growing philatelic sales. The successful reestablishment of the flax industry in 1907 did much to counter these problems, generating considerable income during the war years. Lace making was encouraged as an island-industry during the pre-war period, initiated by Emily Jackson in 1890 and a lace-making school was opened in 1908. Two men, known as the Prosperous Bay Murderers, were hanged in 1905. A paper published in 2017 has proved that reports of a fish-canning factory opening and closing in 1909 because of an unusual shortage of
