High energy cosmic ray extensive air showers.

This review concerns itself with papers on four subjects from HE 3.1, 3.3, 3.4 and 3.5 sessions. The subjects include 1. Shower front fluctuations with applications to mini-arrays. 2. Cherenkov Light and shower front timing differences for photon and proton initiated EAS. 3. The detection of ultra-high energy EAS by very low frequency (VLF) radio signals. 4. Properties of EAS at greater than PeV energy. These include the study of electron, muon, and Cherenkov light lateral distribution functions, the average Xm x dependence on energy, and the value of the proton-air total inelastic cross-section.
