Abstract
It is necessary to invoke a fast-developing air shower model to interpret the measurements of signal rise-times observed at about 500 m from the axis of extensive air showers (EAS) with primary energy near 3*1017 eV. Fluctuations in these rise-times indicate that the primary cosmic rays at this energy consist of at least 40% protons.Keywords
