The spectrum of the cosmic ray produced neutrons was measured between 1 and 10MeV as a function of altitude. The detectors used were organic liquid scintillators to which a pulse shape discrimination technique was applied to select pulses of recoil protons. The proton spectrum was converted to the neutron spectrum by making use of response function of the detectors. The best fit of the neutron spectrum between 2 and 10MeV is φ_n(E_n) = 0.30 exp (-0.0046x)E_n^<-0.77-0.0010x> neutrons/cm^2 sec. MeV, where x is an altitude in g/cm^2. The flux of neutrons of the same range of energy is dependent on altitude as exp (-0.0063x) in a good approximation.
