Mawson, 1929-1930 



Sir Douglas Mawson is in command of an expedition 

 whose main purpose is to explore the shallow seas and 

 coasts south of the Indian Ocean. Captain John King 

 Davis is in charge of the ship, which is Scott's old 

 vessel the "Discovery." They left Cape Town on Octo- 

 ber 19th, 1929, and called at the Crozet group and 

 then at Kerguelen and Heard islands. On December 

 20th the ship crossed the Antarctic Circle in 73° E. 

 On the last day of the year she was on the Circle in 

 65° E. longitude, and here the scout aeroplane was 

 put in use. Land could be seen about fifty miles to 

 the south, flanked by a narrow belt of open w^ater. The 

 explorations are still in progress. A full equipment 

 for sounding and dredging is carried, including an echo 

 sounding machine.^
