%X An examination is made of possible primary cosmic ray energy spectra which are consistent with observed air shower size spectra. At the size spectrum knee, it is necessary to have a very sharp primary spectrum break in order to be consistent with both the size spectrum and also air shower ftuctuations. Such a break may be due to energy loss at the cosmic ray source.
