in the mid-1930s by the American School of Indic and Iranian Studies and the Boston Museum of Fine Arts, where several important details of this ancient city was investigated. Town planning For building houses, baked bricks were used extensively at Chanhudaro and Mohenjo-daro. Several constructions were identified as workshops or industrial quarters and some of the buildings of Chanhudaro might have been warehouses. Industrial activity Evidence of shell working was found at Chanhudaro and bangles and ladles were made at this site. Harappan seals were made generally in bigger towns like Harappa, Mohenjadaro and Chanhudaro which were involved with administrative network. Artefacts found Copper knives, spears, razors, tools, axes, vessels and dishes were found, causing this site to be nicknamed the "Sheffield of India" by Earnest Mackay. Copper fish hooks were also recovered from this site. Terracotta cart models, a small terracotta bird which when blown acts as a whistle, plates and dishes were found. Male spear thrower or dancer - a broken statue (4.1cm) is of much importance, found at Chanhudaro, is now displayed at Museum of Fine Arts, Boston, USA. Indus Seals are also found at Chanhudaro and Chanhudaro is considered one of the centres where seals were manufactured. The scale of craft production at Chanhudaro seems much greater than that at Mohenjodaro, perhaps taking up half of town for this activity. Bead making factory An Impressive workshop, recognised as Bead Making Factory, was found at Chanhudaro, which included a furnace. Shell bangles, beads of many materials, stealite seals and metal works were manufactured at Chanhudaro. A wide variety of materials were used to make beads here, ranging from precious stones like carnelian, jasper, quartz; metals like gold, copper and bronze; and even shell, terracotta (burnt clay) or faience (silica or sand mixed with gum and colour and then burned). These beads were made in a variety of shapes like discs, cylindrical, spherical, segmented or barrel-like. Softer materials like steatite could be moulded easily while other rocks were worked with a paste of steatite powder to make different shapes of beads. Harder stones resulted in geometrical beads. Cultivation Sesame, which is a native of South Africa, is known from number of Harappan sites, including Chanhudaro, probably grown for oil. Peas are also grown at Chanhudaro. Importance In respect of Indus Script, ||/ sign is only found on inscriptions found at Chanhudaro. It occurred on eleven objects, (around one
