he visited the South Pass, as a mem- ber of Mr. J. B. Ead's Advisory Board, and remained in constant commanication with that distin- guished engineer till the summer of 1879, when Mr. Bad's well- planned operations to deepen the South Pass and Mouth, by means of parallel jetties, as at Sulina, were crowned with complete suc- cess. In 1875-77, he acted as Con- sulting Engineer to the Cattewater Commissioners for the Cattewater Breakwater at Plymouth. In May, 1879, he was appointed a member of the Panama Congress, but ab- stained from voting in favour of M. de Lesseps' Panama-Colon pro- ject, as he considered that the engineering data collected up to that time were insufficient to deter- mine satisfactorily the best route for a ship canal across the Isthmus. In Sept. 1879, on the nomination of the Board of Trade, he acted as um- pire in a dispute between the Thames Conservancy and the Metropolitan Board of Works. In 1881 he pre- pared detailed surveys, plans, and estimates for the enlargement of the harbour of Eustendjie, in Roumania. He is the author of two papers on " The ^ Delta of the Danube," and of " Notes on Public Works in the United States and Canada." He has been decorated with the Orders of the Mediidie and the Star of Eoumania, and has re- ceived the Stephenson prize, the Tel- ford medal, the Watt medal, the Telford premium, and the Manby premium, from the Institution of Civil Engineers.
