DRYING OF SLUDGE 129 charges for transportation are excessive. At London the dis- tance is about G2 miles (100 km.), at Manchester and Salford 50 miles (80 km.). London has a whole fleet of sludge steamers, each of which holds 1120 tons (1000 long tons) and costs $142,800 (600,000 M.), besides large iro...n tanks where the sludge is stored until the arrival of the steamer. Manchester and Salford have each one steamer. Three trips a week are made on an average. A 670 ton (600 long ton) steamer cost $57,120 (240,000 M.) in 1895 for Salford. Removal there costs about 17 cts. per ton [80 pfg. per long ton (1015 kg.)] of wet sludge; in Manchester, in 1902-3, 16.6 cts. per ton (78 pfg. per long ton).'
