- Abstract:
Aztecs tapped the sap of Hevea brasiliensis much as American Indians bled sugar maples for their sweet syrup. But the hevea rubber tree yielded something quite inedible - a thick, milky liquid we call latex. The Aztecs used it to make a hard, dense ball for playing games. [ABSTRACT FROM PUBLISHER]
