In the article "Man's first encounters with metallurgy" by T. A. Wertime (4 Dec., p. 1257) the interpretation of the kinds of shading used in Table 1 was printed in reverse order. The correct order. is (i) Bronze. (ii) Smelting and closed mold casting of copper from ores. (iii) Melting and open mold casting of native copper. (iv) Hammering and annealing of native copper. The shading itself is correct. In Table 3, Tell Asmar was erroneously noted as being in Iran; it is located in Iraq.
