It is argued, following Stahler (1985), that in young galactic clusters both the suggested exponential increase in star-formation rates with time and the mass-age correlation are artifacts of incorrectly assigning pre-main-sequence ages to main-sequence stars. Quantitative arguments are presented for simultaneous formation of stars with different masses (contemporaneous star formation) in such clusters and a method is presented for determining star-formation histories and the ages of young galactic clusters (i.e., clusters in which pre-main-sequence stars are detectable). 25 references.
