"DEATH OF ARCHIBALD CAMPBELL, ESQ.

At midnight on Sunday passed away to his post the soul of Archibald Campbell, Esq. Cut off in the bloom of manhood and the meridian of a successful life, he has rendered up his life to the onset of his terrible malady. For several days the fever which rioted rampant in his system seemed somewhat in abeyance, and serious fears were not entertained for his recovery; but the danger was hovering near, and when least expected the silent messenger came. It is not too much to say that our dead friend was universally regretted, and a deep sorrow for the event, and sympathy for the bereaved, is expressed by the community generally.
The subject of this obituary notice was born in the Township of Drummond in the early days of its settlement, and was one of a numerous family of brothers, some of whom have attained marked positions in their native country. The parents were of Highland nativity, and emigrated to this country among the first settlers, enduring the hardships and privations peculiar to the experience of the early pioneers. Mr. Campbell has resided in Perth for several years past, and held at the time of his death the offices of Division Court Clerk and Official Assignee, besides several minor offices. He was also Secretary of the South Riding of the Lanark Agricultural Society. In his official capacity he made many warm friends, constantly adding acquisitions to his list by his kindliness of manner and obliging cordiality; and we venture to say few will deny that his death has added few to his garner in this vicinity who will be more sincerely regretted, or more sacredly treasured in memory.
On Wednesday at 2 o'clock the mournful cortege bearing the remains proceeded to Elmwood Cemetery followed by many friends and acquaintances, and brethren of the Masonic fraternity, on reaching which all that was mortal was consigned to their last resting place with Masonic ceremonial, many participating in this last sad office of a long farewell until the day breaks and the night shadow flee away. In conclusion, we earnestly offer our sympathies and condolence to the bereaved assuring them in their affliction that 'there is One who doeth well what seemeth best in His might.'
The remains of our deceased citizen were deposited in their last resting place with Masonic honors, Mr. Campbell being a prominent member of the Order, and secretary of the Lodge in Perth. Large numbers of the brethren from Almonte, Arnprior, Pakenham, Carleton-Place, Lanark, Newboro', and Merrickville, joined with their fellow Masons in Perth in paying the last earthly tribute of respect to their deceased brother. The funeral took place to Elmwood Cemetery, on Wednesday last, and comprised one of the largest assemblages of all classes and creeds we have ever seen in Perth."
