Sir, The members of the Sandhurst Branch of the Australian Natives Association feel they cannot allow you to sever your connection with them without some expression of the esteem in which you are held by them and of the good will towards you.

WE feel that you can justly take pride in the share of that result and that it forms a further illustration of the pre-eminent zeal which from the first you have displayed inn the interests of the Association generally. While recognising the loss the Branch will sustain by yourd departure, we heartily congratulate you on your promotion and wish you every success in the new sphere of action to which you duty calls you.
