I think I would put it more in this shape: that 
Lord Kimberley
                     had not intended, as rightly understood by the subordinate
                     officers who will after the Union remain in the service of the
                     local provincial administration, to refer to them in the words
                     quoted by 
Mr Musgrave from his Ldp's despatch of 
19
                        Jan (144) [No. 3].
                     
                     
                     
                     The cases of those higher officers who would be
                     likely to lose their offices from political causes was then
                     under consideration, and the 9 par of 
Govr Musgrave's
                     despatch of 
Nov 17
                     
                     
                     
                     
                     (to which
                     that of 
Lord Kimberley in 144 [No. 3] was a reply) expressly
                     distinguished from it the different case of the subordinate
                     officers. The Dominion Government do not appear to have raised
                     any question as to the continued employment of these subordinate
                     officers, (and 
Lord Kimberley sees no reason whatever to doubt
                     that they will notwithstanding the constitutional changes be
                     continued in their present or in equally good positions)
                     
                     
                     
                     
                        
                           Omit this. I don't feel quite so sure.
                           
                        
                      
                     
                     But [revised to read: and] he does not think he would be doing
                     any service to this class of officers if he were to hold out to
                     them any expectation of his being able to provide them with
                     employment in other colonies.
