K 2649, chalk, was found associated with the clay, 2| ft. below the surface, 

 at Zircon Creek, 300 ft, above sea-level, at head of Perseverance Harbour, Camp- 

 bell Island, at same spot, and below where samples of soils K 2647-8 were taken 

 on the 13th January, 1909. 



K 2662 is a white siliceous limestone, collected on the 13th January, 1909, from 

 a face eroded by the sea, in a bay at the head of Perseverance Harbour, Campbell 

 Island. Samples of it are soft and white on the outside, but contain a hard and 

 close-grained nucleus resembling lithographic stone.

K 3005 and K 3005a were collected from a very hard basaltic boulder with 

 crystals of olivine, from the sea-beach at the homestead, Perseverance Harbour, 

 Campbell Island, on the 13th January, 1909. The analysis of the weathered and 

 unweathered portions show that the weathering has chiefly resulted in a diminution 

 of iron and magnesia. 



K 3004 is an altered sedimentary rock (phyllitic argillite) containing quartz, 

 mica, and pyrites, collected on the 12th January, 1909, from Perseverance Harbour, 

 on beach under Mount Honey. 



K 2671 is an iron pan from the same locality. It differs from other iron pans 

 chiefly in the excess of alumina and the presence of the rare earths. It is interesting 

 to compare it with K 2616, a bog-iron, which was collected at the Ocean Beach, 

 Bluff, below a layer of humus at the littoral, in January, 1909. The iron in this 

 sample exists as hydrated ferric oxide, with a small quantity of organic matter. It is 

 similar in appearance and analysis to the bog-iron ore mined in Sweden and Ireland.
