Commonwealth Bay, Adelie Land, 1912, 1913. Observa- 

 tions were made at five stations, designated A, B, C, 

 D. and E. 



Station A. During the 11 months of occupation by 

 the Australasian Antarctic Expedition, observations 

 were made regularly in the absolute hut situated about 

 300 yards (274 meters) northeast of winter hut quar- 

 ters. 



Station B. In excavation in ice about one-half mile 

 fO.S kilometer) from first appearance of solid rock, 

 about 600 meters from morainic termination of glacier 

 at altitude of 345 feet (105 meters) above sea level, 

 3,849 feet (1,173 meters) from ,4. True bearings: 

 west azimuth mark of .4, 3,820 feet (1,164 meters), 

 14704',2;.4, 16656'. 



Station C. On rocky ridge west of boat harbor, 

 about 800 feet (244 meters) northwest of hut quarters, 

 about 2 chains (40 meters) north of spot where west 

 azimuth mark of .4 was subsequently placed. 



Station D. Two chains (40 meters) east of absolute 

 hut. 



Station E. By sledge meter 11 miles 750 yards 

 (IS. 4 kilometers) practically due south of Common- 

 wealth Bay, 1,990 feet (581.9 meters) above sea level, 

 on slight rise beyond which plateau rises evenly for 

 several miles. The sledge journey from absolute hut 

 was over ice heavily crevasserl, with no appearance of 

 rock . 



Eastern Sledge Journey, 1912. The Australasian Antarctic 

 Expedition in November 1912 sent out a party which 

 made observations of declination and inclination along 

 coast to eastward, at points which are generally 

 described by the direction of the route from station 

 to station, and by distance obtained by sledge meter 

 running continuously from winter quarters to last 

 point at which observations were made. These 

 points are luimbered in order of occupation and are 

 further described by latitude and longitude, which are 

 given for each ease in the Tabic of Results. 



1. At 55| miles (89.7 kilometers) southeast of Com- 

 monwealth Bay, on ice-covered hill about 1,000 feet 

 (305 meters) above surrounding country. Rock out- 

 croi) was not evident from this hill, but was visible 

 on similar hill, later referred to as Mount Aurora, 

 5 to 8 miles (8 to 13 kilometers) south. 



2. At 73J miles (118.7 kilometers) southeast from 

 winter quarters. 



3. At 107 miles (172.2 kilometers) southeast from 

 winter quarters, on barrier about 7 miles (11 kilo-

meters) from tongue of ice pushed out by pressure of a 

 glacier, and perhaps 20 miles (32 kilometers) from 

 shore. 



4. On sea ice at 112 miles (180.2 kilometers) by 

 meter from winter quarters and nearly due east of 

 station 3. 



5. On sea ice at 152j miles (247.7 kilometers) from 

 winter quarters, .southeast of station 4, and 20 or 30 

 miles (32 or 48 kilometers) out from apparent coast 

 line. 



6. On sea ice 200 miles (321.9 kilometers) from 

 winter quarters, southeast of station 5. 



7. A station auxiliary to station 8 at 220 miles 

 (354.1 kilometers). 



8. On sea ice at 223 miles (358.9 kilometers) by 

 sledge meter, and south-southeast from station 6. 



9. On barrier at 270 miles (434.5 kilometers) by 

 sledge meter from winter quarters, and south-southeast 

 of station 7. This is farthest point reached by eastern 

 party, and is about 17 miles (27.4 kilometers) north- 

 northeast of large rock outcrop noted as Di'eadnought 

 Bluff. 



10. Southwest of station 9, 5 miles (8 kilometers) 

 toward Dreadnought Bluff from 270-mile Camp. 



11. Southwest of station 9, 13j miles 21.3 kilo- 

 meters) toward Dreadnought Bluff from 270-mile 

 Camp. 



12. On retm-n journey at rock outcrop called Pen- 

 guin Point, about 16 miles (25.7 kilometers) south- 

 southeast of 107-mile Camp (station 3). The sledge 

 meter running continuously since leaving winter 

 quarters read 417 miles (671.1 kilometers). 



13. On glacial tongue on barrier, about 10 miles 

 (16 kilometers) southeast of 55-mile Camp and about 

 same distance east of Mount Aurora, at sledge-meter 

 reading 464 J miles (747,1 kilometers). 



Southern Sledge Journey, 1912. In November 1912 the 

 Australasian Antarctic Expedition sent out a party 

 from the winter quarters at Commonwealth Bay, 

 whose route lay toward the highlands of the interior. 

 Stations, which were occupied at intervals, are 

 described by the general direction of the course fol- 

 lowed and the distance by sledge meter from the point 

 of departure at winter quarters. 



1. At 30 miles (48 kilometers) on course 10 east of 

 south. Height above sea level 3,415 feet (1,041 

 meters). 



2. At 67| miles (108.6 kilometers) on course 10 

 east of .south, at an elevation of 2,221 feet (677 meters) 

 above sea level. An auxiliary station, 2 A, was occu- 

 pied 80 meters east of declination station. 



3. At 100| miles (162 kilometers) on course south 

 45 east from station 2, at an elevation of 2,753 feet 

 (839 meters). 



4. .4t 174.8 miles (281.3 kilometers) after traversing 

 courses as follows: nearly due south to 120 miles, 

 south 7 west to 132 miles, and south 45 east to sta- 

 tion. 



5. At 200 miles (322 kilometers) following course 

 from station 4 that varied from 10 to 20 east of 

 south. This point was reoccupied on retiu'n. 



6. At 249 miles (400,7 kilometers) on course from 

 station 5 bearing 45 east of south. This point was 

 I'eoccupied on return, 



7. At 301 miles (484 kilometei-s) after continuing 

 southeasterly course pursued since leaving station 5. 

 This station was most southerly reached and lies at an 

 elevation of 5,900 feet (1,798 meters) above sea level, 



8. On return journey about 33 miles (53 kilometers) 

 north of station 4 or about 142 miles (229 kilometers) 

 from winter quarters, sledge meter reading 460 miles 

 (740 kilometers), running continuously from starting- 

 point at Commonwealth Bay.
