stones, varying in 6ize from a few inches up to several feet 

 in diameter. Near Glen Osmond, large villa residences and 

 highly cultivated grounds have obscured the natural features, 

 but wherever the ground exists in its natural condition large 

 stones can be noted at the surface, usually strongly embedded 

 in the ground. The distribution of large stones follows, in 

 the main, the direction of the creek channel, sometimes best 

 developed on the one side and sometimes on the other. In 

 the Ridge Park, at Glen Osmond, on the western side of the 

 park, there is a conspicuous group of about thirty examples, 

 situated on the right bank of the creek, the largest stone 

 measuring 3 ft. 6 in. in length. They can be seen on a newly 

 laid out road, on the opposite side of the creek, and in 

 paddocks towards Fullarton. 



The most important assemblage of these transported 

 blocks occurs on the eastern side of the Fullarton Road, a 

 little south of Fisher Street, fully a mile from their source. 

 They occur in great numbers, some of extraordinary size, on 

 the grounds of Mr. Thomas Baulderstone and adjoining 

 properties. The largest of these transported blocks measured 

 9 ft. 6 in. long by 3 ft. 6 in. broad, and 2 ft. 9 in. above 

 the ground. This stone probably weighs not less than 

 six tons. Near the above is a large tabular mass giving 

 the measurements 5 ft. 6 in. by 7 ft. embedded almost level 

 with the surface of the ground. Another measured 5 ft. long, 

 4 ft. 6 in. wide, and 1 ft. 9 in. out of the ground. Another, 

 irregular in shape, measured 4 ft. 10 in. long, by 3 ft. 5 in. at 

 greatest width, and 2 ft. 10 in. out of the ground. In one 

 part of Mr. Baulderstone's paddock there is a group of eight 

 quartzites, close together, each of which Mr. Baulderstone 

 calculated would weigh something like five tons, and there 

 are scores of quartzite. blocks that equal 2 ft. or more in 

 length. To relieve the ground of these obstructions to 

 cultivation a hundred, or more, have been dragged to the 

 side of the paddock and form a conspicuous line at the fence. 

 (See plate vii.) From the stones of this paddock Mr. 

 Baulderstone has built his house, outhouses, and enclosing 

 walls, which exhibit stones of unusual size used for such 

 purposes. When this ground was open for selection, no one 

 wanted it, as it was regarded as a quartzite outcrop, and 

 was actually offered for 6ale as a possible quarry. The 

 circumstances whidh gave rise to the distribution of such 

 a large number of angular blocks of stone are evidently 

 abnormal and require some geological explanation to account 

 for their presence. Under certain circumstances ice agency 

 might be credited with the transportation of such large stones, 

 but such a view is not supported by any collateral evidences.
