cottages and fine homes of the period can still be seen. Whereas Glebe enjoyed a resurgence, the shanties and brothels of Wapping were condemned, and many were destroyed to make way for new developments, such as the wool store, that survives to this day as the Old Woolstore Hotel. Part of the area had already been reclaimed in the early 1850s for the construction of the Hobart Gas Works, which was opened amidst much fanfare on 9 March 1857, bringing gas lighting to the streets of Hobart Town for the first time. In 1870, the -high shot tower was constructed by Joseph Moir at Taroona, south of Hobart, for the purpose of manufacturing shot for the Tasmanian Colonial Forces. It used gravity to drop molten lead down the inside of the tower, which formed spherical pellets and solidify when it landed in cold water at the base of the tower. The Hobart Electric Tramway Company commenced operation in 1893, providing Hobart with the first complete electric tramway in the Southern Hemisphere. The tramway proved very popular and the route from the city to Sandy Bay Beach was always crowded in summers during the early 20th century. The tramways expanded rapidly, and suburban growth was encouraged by the lines. By the early 20th century, tramlines ran from the city depot to North Hobart, Lenah Valley, Springfield, Glenorchy, Cascade Brewery, Proctor's Road, and Sandy Bay. Single deck trams were introduced in 1906, and the Hobart City Council took over control of the company in 1912, renaming it the Hobart Metropolitan Tramways. Electric trolley buses were introduced in 1935. An economic depression struck Hobart in the early 1890s, but some companies succeeded in spite of it. In 1891 Henry Jones established a jam factory in which he began to manufacture preserved jams and spreads using locally sourced high quality fruit produce. The factory soon came to be known simply as 'The Jam Factory' to locals, and was soon exporting jam throughout the British Empire. His company soon grew into a substantial business under the name of Henry Jones IXL, and established a second factory in Victoria. In 1895 American writer Mark Twain visited Hobart as part of his worldwide tour of the British Empire, and wrote about his visit in his 1897 book Following the Equator. In it he writes: Early 20th century Hobart had been badly affected by the depression of the
