A 3-NM-64 neutron monitor and a 2-MT-64 muon monitor were operated at 29 sites near sea level and on mountains on the western seaboard of the USA and in Hawaii in May, June, and July, 1966, in continuation of the latitude survey begun in 1965 and reported in papers I and II of this set of five papers. The original results and also the corrections for temperature structure of the atmosphere and for secular variations of the cosmic radiation are given in detail. While the overland equipment was at its highest altitude on Mt. Hood (2.4 GV) and on the summits of Mt. Palomar (5.7 GV) and Mt. Haleakela (13.3 GV), an airborne neutron monitor was operated at seven different levels between 3000 m and 12 000 m. The pressure-measuring equipment and also the neutron monitor in the aircraft were calibrated in terms of the overland instruments while the aircraft was at the same altitude as the overland equipment on the summit of Mt. Haleakela.

The momentum distribution and charge ratio of the penetrating component of the cosmic radiation at sea-level have been determined over the 'momentum range- 0�24-58 BeVlc at a geomagnetic latitude of 47 oS. The measurements were performed in the vertical direction and at zenith angles of 30� and 60� in the eastern and western azimuths.

The flux of quarks in air shower cores at sea level is estimated from four different types of experiments. All four estimates agree and yield a quark flux of 8 x 10-12 cm-2 s- 1 sr- 1 ? The calculated concentration of quarks in the Earth's crust resulting from this flux is compared with that found in niobium in the Stanford quark search.
