According to the white paper of the commission of inquiry into the 1894 crisis, Ames, a British colonial administrator, said that the original name for Jos was Gwosh in Afizere (the first settlers in the area) language which was a village situated at the current site of the city; according to Ames, the Hausa, who arrived there after, wrongly pronounced Gwosh as Jos and it stuck. Another version was that "Jos" came from the word "Jasad" meaning body. To distinguish it from the hill tops, it was called "Jas", which was mis-pronounced by the British as "Jos". It grew rapidly after the British discovered vast tin deposits in the vicinity. Both tin and columbite were extensively mined in the area up until the 1960s. They were transported by railway to both Port Harcourt and Lagos on the coast, then exported from those ports. Jos is still often referred to as "Tin City". It was made capital of Benue-Plateau State in 1967, and became the capital of the new Plateau State in 1975.
