This is a difficult one.

I think parts of it read:

Capt Goodyear taken on at 15/- to organise native & Cape Boys for defence of this ...... (I can't make head or tail of line three)

Corps of cadet orderlies assembled. This will relieve a number of mounted orderlies to carry on their proper duties.

Thank you, Neville, for looking into this. Your reading fits the sense very well.
