Remarkable for his great endurance of fatigue and exertion, and as being one of the best and quickest surveyors in the Ordnance. In his early career in Ireland, it is said, he once walked twenty-two miles to work, surveyed twelve miles of lines, and returned the same evening—twenty-two miles—to his quarters! This was considered at the time to be fair progress for six days; indeed, it was facetiously said of him that he carried on his work by _moonlight_. He was also clever as an observer with the two-feet theodolite, and the accuracy of his arcs was so rigidly faithful, that an officer visited him specially to watch his work, and test the value of his services. More than twenty-one years he took part in the national surveys, and had the local superintendence for many years of large parties dispersed over extensive districts. He also assisted with much credit in the survey of the disputed territory in North America; and, receiving for his good conduct and long services a gratuity and silver medal, was discharged from the corps in January, 1851. Soon afterwards he emigrated to Canada. Footnote 3: ‘Companion to Almanac,’ 1849, p. 37. Footnote 4: Ibid., p. 38. Footnote 5: Ibid.

There was no class of persons who so soon got into productive civil service.”—Ibid. Footnote 8: ‘Illustrated London News,’ June 24, 1848. Footnote 9: Ibid. Footnote 10: The privates here named have died under rather singular circumstances; Porteous _suddenly_, in September, 1853, when encamped on Brandon-hill; Pemble in June, 1854, at Elvanfoot, in Lanarkshire, from exhaustion and exposure to stormy weather. The latter had been sent from the camp to build a pile for trigonometrical purposes, and next evening, after a fatiguing day’s work, he was returning to the station, when he lay down to rest himself by the side of a mountain stream, and perished. Both these soldiers were the chief practical workmen in the formation of the structures for the observatories. At lofty heights, where the senses of most men would paralyze, borne up on shaking props or slender supports, they calmly carried on their dangerous operations with spirit, activity, and ingenuity.
