52 THE VOYAGE OF THE 'DISCOVERY' 



in which he assisted the scientific work of the expedition, 

 whilst, thanks to his ability with the camera, in the course of 

 his work as photographer-in-chief he produced the most excel- 

 lent pictures that have ever been obtained by a Polar expedition. 

 Our geologist, Hartley T. Ferrar, joined us only shortly 

 before the ' Discovery ' sailed. Though born in Ireland he 

 had spent the early years of his life in South Africa, but he 

 had returned home to be educated at Oundle School and at 

 Sidney Sussex College, Cambridge. Events went very rapidly 

 for Ferrar at the end of his university career; in June 1901 he 

 took honours in the Natural Science Tripos, in July he was 

 appointed to the Antarctic Expedition, and in August he sailed 

 for the Far South. He had very little time, therefore, to pre- 

 pare himself for his important work, but he did his best to 

 make up this deficiency by a steady application to his books 

 and an increased activity when he arrived at the scene of his 

 work. As will be seen later, the result of Ferrar's work was to 

 throw considerable light on the structure of a vast land mass, 

 no inconsiderable portion of the surface of the earth ; it was a 

 result, therefore, that cannot but be highly important to geolo- 

 gical science, and it was achieved by physical labour which 

 might not have been within the powers of a more experienced 

 geologist. 



Owing to the medical rejection of a former candidate for 

 the post our physicist, Louis Bernacchi, did not join us until 

 we reached New Zealand. Bernacchi had been born and 

 educated in Tasmania ; in 1895 he had joined the Melbourne 

 Observatory as a student, and had there gained his knowledge 

 of the special physical work which he has since steadily pursued. 

 In July 1898 he had joined Sir George Newnes's Expedition 

 to Cape Adare, and the valuable magnetic observations which 

 he then made showed that he was capable of undertaking the 

 more extensive programme connected with this science pro- 

 posed for our shore station. The delicate instruments which 

 he manipulated, and the difficulties he had with them, will be 

 described in due course.
