While in search of iron ore deposits, Charles Weld, an American geologist and Dorabji Tata were travelling in present-day Chhattisgarh in 1904 with a view to build a big Iron and Steel industry in India. In this course, they came in contact with tribal people carrying basket loads of iron ore, who helped them in the discovery of a source of iron. Identify the particular tribe from below :

In 1904, Charles Weld, an American geologist, and Dorabji Tata (the eldest son of Jamsetji Tata) were exploring the Rajhara Hills in present-day Chhattisgarh to find a source of high-quality iron ore for their proposed steel plant. They encountered the Agarias, a community of traditional iron smelters, carrying baskets of iron ore.

• The Agarias led them to the hills which contained one of the finest iron ore deposits in the world.
• While the Rajhara Hills provided the ore, the lack of a nearby water source led the Tatas to eventually set up their factory at Sakchi (now Jamshedpur) near the confluence of the Subarnarekha and Kharkai rivers.
• The Agarias were instrumental in this discovery, though their traditional craft declined as large-scale industrial production took over. This historical account is prominently featured in NCERT Class 8 History.
