In July, 1948, the writer visited Roma with the object of collecting material for micropalaeontological study as no similar investigation had been carried out on the sediments in the area which Whitehouse refers to as the Roma Series. Systematic collections were made and the results of the examination so far have been entirely satisfactory. About two hundred samples were collected for examination for foraminifera and where possible specimens of typical species of the larger fossils of the Roma series were gathered. This report comprises a brief overview of the visit, notes on the samples, and notes on foraminiferal assemblages in the deposits in the Roma area.

In the Preliminary Report on Cambrian Fossils (1948/073) collected in the Northern Territory, locality B.68, 20.4 miles west of Djarra, was placed among the localities with the western development of the Middle Cambrian Xystridura-fauna. Mr. P.B. Nye has drawn the writer's attention to the fact that the Djarra locality is in Queensland 90 miles east from the Northern Territory border; i.e. far away from those localities with a typical "western fauna" and near those with an "eastern fauna". A re-examination of the fossils and palaeogeographical interpretation of the locality near Djarra therefore becomes necessary.

Bores sunk at Cremorne in 1891 struck coal at approximately 2802 feet. A company was formed to work the coal, but was refused permission to operate at Cremorne. A site at Balmain was secured, and the Birthday Shaft was sunk to a depth of 2,937 feet between 1897 and 1902. This report provides an overview of the occurrence of natural gas and workings for the period 1897 to 1948. Gas yields, commercial production, leakage problems, and the use of testing to determine the behaviour of gas in the mine are the key subjects that are addressed in this report.

A geological investigation was carried out by the writer. The aim was to check the previous mapping of the geology, and if necessary, to assist the Magnetician in locating a suitable site for magnetic observations. Some aspects of geomorphology, and the reconnaissance survey work carried out are discussed in this report.

The area with which this report deals is situated on the upper reaches of Coree Creek, just below its junction with Condor Creek. Two possible dam sites were examined on Coree Creek, a quarter of a mile below Condor Creek. Mapping, physiography, general geology, structural geology, engineering geology, and sources of aggregate and sand are discussed. A petrological appendix is included.

This report describes the physiography and the history of the development of the North Stradbroke Island. Two accompanying plates are included.

This progress report briefly describes the developments of chief interest in the Cobar geophysical survey up to 4th June, 1948. Geophysical, magnetic, geological, and gravity surveys were completed in the area between March, 1947, and April, 1948. A summary of the results of drilling and survey work completed to date is given in this report. Recommendations for future work are discussed. Plans showing results from the Cobar geophysical survey have been included.

This report describes the results of a micropalaeontological examination of samples taken from the depth of 1 to 505 feet down.

This report describes the results of a micropalaeontological examination of samples taken from a depth of 1 to 266 feet down.

Report on gravity survey work and drill testing completed at Leigh Creek between 1947 and 1948. Observations and results are briefly discussed.
