N2  - The variation of (X-track density in boron-loaded emulsions and the star rate in C2 emulsions have been measured at the same sites at mountain altitudes at two latitudes. The (X-count is proportional to the slow neutron density in the atmosphere while the stars arise chiefly from fast neutrons. The variation with altitude can be represented in each case by a simple exponential of the form: l=loe-X/L . Values were derived for the attenuation length L for each latitude:
