From "Report of the Superintendent of the Coast Survey Showing the Progress of the Survey During the Year 1868."
Assistant Samuel A. Gilbert died at St. Paul, Minnesota, on the 9th of June. He was by brevet, a brigadier general, for active and meritorious services in the field in the recent war; and as a civilian, was one of the most experienced of the assistants in triangulation and topography.
The resolution passed at a meeting of his associates, a few days after his decease, well express the sterling qualities of the man, as evinced within my own knowledge during the short period of my personal acquaintance with him.
In the hope of recovering from the effects of hardships undergone in the military service, Assistant Gilbert left his home and his interesting family in Zanesville, Ohio, and dwelt during the greater part of the year in St. Paul. The cessation from active duty brought some measure of personal comfort, but failed to restore strength to his powerful frame and constitution, which finally wasted away in consumption.
