Mr. H.T Clarke late Native Secretary left for the Bay of Islands yesterday where we believe he will take up his residence permanently. Mr. Clarke is a Native of New Zealand his father having been one of the early missionaries and for many years Protector of aborigines. Mr. Clarke was attached to the troops in Heke's War as interpreter and was wounded in one of the engagements, which took place. He was for several years thereafter in the Government Service but left it and resided for several years at the Bay of Islands. He then again rejoined the Government Service and was appointed Resident Magistrate and Civil Commissioner at Tauranga. In this position he had a great deal of troublesome and dangerous work to undertake in the Tauranga and Rotorua Districts especially during the continuance of the Pirirakau outbreak. He continued at Tauranga for about 10 years and was transferred to Wellington to occupy the post of permanent head of the Native Department. This office he resigned a few months ago and on his retirement he received a handsome presentation from the officers of the department. Mr. Clarke in all the offices he has held has been highly esteemed by Europeans and Māoris. He had ever been desirous to secure the best interests of the native race. The best wishes of all who have known him follow him into his retirement.
