On the Schawinsland near Friedburg (48 deg N, 8 deg E, 1230 m) extensive showers were recorded from November 1953 to October 1956. The apparatus consists of 10 trays of G-M counters with an effective area of 1700 cm/ sup 2/ each. Five of these trays (1 through 51 are located on a straight line at equal separations, the two extreme ones having a distance of 11 m. Three coincidences of the two outer and the center trays (1, 3, 5) and five coincidences of all five trays were recorded. Mean densities, counting ratios, estimated particle numbers, and energies for the various events are recorded. The counting rates were also calculated using the number spectrum of Greisen. Excellent agreement is found with the measured rates at low energies. A multiple correlation analysis between daily shower rates, local pressure, and free air temperature was carried out. It was found that partial correlation coefficients with respect to temperature vary little with the level at which the temperature is taken, provided one of the levels between 850 and 300 mb is chosen.
