Sunday May 8th 1898
Our officers availed themselves of a little shooting,
but the only birds that came across ship' path was

pigeons, in the afternoon the missionaries from the
Southern Cross, came on board bringing with them
twenty of their reformed Natives belonging to different
Islands most of them spoke English very well
having been  to the Mission School on Norfolk Island
which they said they liked very well indeed and
was very sorry to have to leave it, they were now
going back to their own islands to teach their own
people about Civilization & the bible, during the
the afternoon our men went away seineing for the
1st time, but was unsuccessful owing to the seine
getting foul of the coral which the bottom is cover-
ed with.

I wasn't sure if  had correctly read seineing and seine.
Seining is I have discovered a type of large net fishing that is made to hang vertically in the water by weights at the lower edge and floats at the top.

I have discovered another journal at http://anglicanhistory.org/oceania/island_mission1869/25.html when searching for info on Norfolk Island Missionary schoool

Here is an extract mentioned the Schooner Southern Star
[277] CHAPTER XXV. ON Easter Tuesday, 1867, the Southern Cross conveyed the bulk of the Mission School, with the Bishop, Mr. Codrington, and Mr. Bice, from Kohimarama to Norfolk Island. Mr. Palmer had spent the summer there, and Mr. Brooke and Mr. Atkin, with the boys under their charge, had been there for a month; so that when the Bishop arrived there, he found his new station in a fair state of preparation, enclosures and outhouses ready, and all in a state of sufficient forwardness to receive the large party who were there to be lodged.
