will be understood that young Smith was brought up under proper
influences and sent forth with the highest ideals of his profession. He
graduated in the "fives" of his class. He was commissioned as a Brevet
Second Lieutenant in the corps of Topographical Engineers, and served
with it continuously till, for convenience and simplicity of
administration, it was merged with the Corps of Engineers after the

Later he was transferred to Florida and made surveys for a ship canal
across the peninsula from the Atlantic to the Gulf of Mexico.
Subsequently he had charge of the Eleventh District in the light-house
service with his headquarters at Detroit. He then became Assistant
Secretary, and finally on the retirement of his friend, Captain

denied. His service in Texas and Florida had brought him in contact
with a number of officers who afterwards became distinguished in the
Civil War. Among the most notable of these were Buell, Joseph E.
Johnston, McClellan, Meade, Burnside and Emory. His light-house service
