It is proposed to construct a wheat storage silo toward the northern end of the Long Plains Railway Yard which is about 40 miles north from Adelaide. Two percussion test bores were drilled at the request of Mr J.A. Corbett, Senior Engineer, S.A. Cooperative Bulk Handling Limited, for the purpose of testing the foundation conditions. In Bore No. 1 sealed tube samples were taken at five foot intervals down to a depth of 50 feet. At all other depths down to the bottom of the bore at 90 feet, open tube samples were taken and extruded into plastic envelopes. Open tube samples only were taken from Bore No. 2 which was finished at 25 feet. The number of blows per feet of penetration were recorded during both open and sealed tube sampling in the two bores. Pocket penetrometer readings were measured in the cohesive sample material. Records of the number of blows per foot of penetration and pocket penetrometer readings are included in the descriptive geological logs of the samples in an appendix. This information is also shown on a cross section drawn through the bores. Also in the appendix are descriptive logs of a 583 feet bore, 2½ miles south west from the site.
