some half dozen other granite boulders varying in size up 

 to several feet in diameter. 



A short distance t'urtner to the westward can be seen two 

 enormous masses of close grained bluish quartzites lying end- 

 ways to the base of the cliffs. The first of these measures 

 thirteen feet six inches by five feet six inches; and the se- 

 cond, which is separated from its companion by only a few 

 feet, is almost as large. Similar boulders of a smaller size 

 are strewn in the vicinity. It must have been ice of great 

 transporting power that could carry stones of such a size as 

 described. 



The cliffs of the Lake near these erratics are about twenty 

 feet in height, and consist intermittently of clay and sand 

 rock. The change from the one feature to the other is»- 

 often very abrupt. The clay is generally very compact, 

 grey in color, with red patches; whilst the sand-rock may be 

 colored white, yellow, or a deep brick-red. The stratigraphi- 

 cal lines are often very bewildering. In places no bedding' 

 planes can be detected, and in others they rapidly alter from 

 the horizontal to nearly vertical direction, accompanied with 

 contortions. 



(d) Munkowurlie Lagoon. — This is a long narrow lagoon 

 running parallel with the road between Yorketown and Port 

 Moorowie. The widest portion of the lagoon is at its sou- 

 thern end, and on the eastern side of this larger basin in the 

 lake two granite boulders are conspicuous. They are visible 

 from the public road at a distance of about a quarter of a 

 mile. 



(e) Moorowie Head Station. — Situated about ten miles- 

 north-west of Yorketown on the edge of the Great Swamp 

 country. I am indebted to Mr. Matthews, of Yorketown, 

 and to Mr. Fowler, of Yararoo, for calling my attenlion f o 

 two erratics of granite which occur near this Station. I was 

 unable to visit the locality, but the independent description 

 given by the gentlemen named agree in every particular. 

 One of the stones referred to measures three feet by eighteen 

 inches, and lies on the east side of the main road in Section 

 No. 38, Hundred of Moorowie. Mr. Fowler describes it as 

 "red granite similar to the granite seen in the cliffs at Cape 

 Spencer." The second of these boulders is described as 

 much larger than the one just referred to, estimated at five 

 feet by three feet, lying on the north side of a small lagoon, 

 in Section No. 37, about three-quarters of a mile from the 

 first mentioned. 



(f) Lagoon at Pentonvale Head Station. — Mr. Matthews, of 

 Yorketown, has a granite boulder in his yard that had been 

 brought from the above ligoon as an object of interest. The-
