his youth he attended the school of Mr. Gregory in this city, where he 

 formed msiny of the warm and close friendships which continued through- 

 out his life. Entering the University of Pennsylvania in his sixteenth 

 year, he graduated in the class of 1863 ; and whilst there developed that 

 marked fondness for mathematical studies which clung to him through 

 life. On leaving the University he entered, as a student, the Rensselaer 

 Polytechnic Institute at Troy, N. Y., graduating in 1865. His standing 

 there was a high one, and on graduating he made an address at the Com- 

 mencement. 



His first active work was as Assistant Engineer on the Allegheny Val- 

 ley Railroad and on the Pennsylvania Railroad, being under Mr. W. H. 

 Wilson, then Chief Engineer, and closely associated in the work of Mr. 

 Joseph M. Wilson. 



His intimate friend, Mr. Walton W. Evans, the eminent engineer, well- 

 known for the high order of his work in South America, sent him to Peru 

 in 1871, to supervise the erection of the first viaduct on the Verrugas 

 Railroad. Being attacked with the Verrugas fever soon after his arrival, 

 which lasted for several months, he was unable to work on the bridge. 

 On his recovery he was appointed Division Engineer of the Callao, Lima 

 and Oroya Railroad, where he remained for some years. 



On relinquishing his position in 1874 he returned to this country, but 

 was again sent by Mr. Evans to South America in 1873 as Engineer of 

 the Southern Railroad of Chile. 



In the interval between his two first visits to South America he was 

 appointed Principal Assistant Engineer of the Main Building of the Cen- 

 tennial Exhibition in Philadelphia. Whilst filling this position he designed 

 the ingenious construction of trusses, forming a central open space, clear 

 of rods, at the junction of the nave and transept of that building. 



From 1876 to 1879 he was Assistant Engineer of the Philadelphia 

 Water Department. 



In 1880 he was appointed Resident Engineer of the Richmond and 

 Allegheny Railroad in Virginia. 



On relinquishing that position he engaged in a general engineering and 

 consulting practice in Philadelphia. 



In the winter of 1893-93 he went to Ecuador as Consulting Engineer 

 on the water works at Guyaquil, at the request of his friend, Mr. A. 

 Millet, who was the engineer and contractor. With this as with every- 

 thing else he undertook, his interest in the success of the undertaking 

 became very great and the exposure he underwent, in consequence, 

 probably cost him his life. His work there was almost completed and he 

 was looking forward to his return in a few days, so as to spend his 

 Christmas with those he loved so tenderly, when he was stricken down 

 with yellow fever. After an illness of about a week he died, on Novem- 

 ber 16, 1893, a stranger in a strange land far from those who now so 

 deeply mourn his loss. 



Mr. Cleeraan was elected a member of this Society October 15, 1885.
