The annual chemisfry contestr conducfed by the Sacramenfo Valhy Section of the American Chemical Society were initiated and have been confinued chiefly through the intered and activity of X r . J. H. Norton, chemistry imtructor at the Sacfo Junior College. The contests fake fhe form of competitive writfen esaminafionson the subject matter of elemenfary chpmhtry. All high schools i n the Sacramnto Valhy, as well as fhe Reno and Sparks high schools of Nevada, are eligible to enter teams.

No special coaching i s given Rosevih t e r n in preparation for the contesfs. The same team won the Pac~xcCoast American Chemical Sociefy confesfi n June, 1934.
