Bock carvings.

The so-called rock carvings are merely outline representations of men, fish, animals, &c. They may be frequently seen on the summit of flat-topped rocks. At Thornton's Hill, Manly, the remains of the representation of a man may be seen. A cart-track has obliterated the body, but the feet and a boomerang, which he held in his hand, are plainly visible. A few yards away from this two fish are represented. A flat rock at Middle Head was covered with the representations of whales, sharks, and other fish. One of the former measured 30 feet or more in length. A flat rock near the Association Ground, Sydney Common, was covered with the representations of kangaroo, opossum, fish, boomerangs, &c. At Berry's Bay some figures also exist. No page 51 mystery whatever may be attached to these marks. I have seen a young man lying on rock whilst others traced his outline and then picked out the line with a tomahawk.
