MARINE SURVEYS.

WORK OF THE TERRA NOVA. [by telegraph.—own CORRESPONDENT.] Christchtjrch, Monday. Lieut. H. L. L. Pennetj,, R.N., commanding officer of the Terra Nova, has explained something of the nature and scope of the work to be done by the ship off the North Cape. He stated that a series of soundings as complete and accurate as possible were to be made by the Terra Nova between the Three Kings and Cape Maria Van Diemen, in order to properly chart the 100 fathom line. He explained that for navigators approaching the northern end of New Zealand from the westward and making land in thick weather, when the land was obscured, and when the sun was not visible for the getting of sights, it was of the utmost importance that they should be able to accurately determine their position by means of soundings. For example the English Channel had been so completely , and accurately ; plotted by soundings that navigators wore able to take ships through in thick weather, confidently determining their positions by meanß of the deep sea sounding machines. Mr. D. C. Leslie, biologist to the expedition, will accompany the Terra Nova during the cruise, with the object of securing specimens of deep sea fauna. As it is unlikely that the vessel will call at any ports during her cruise all the stores and supplies for the three months have been shipped at'; Lyttelton. The Terra Nova will call at Mangonui at intervals during her cruise to receive and despatch mails, etc. ~ . . '■:."■
