We have seen how he refused to go to Brazil. He was also wanted at Jacksonville, Florida, where the citizens called him in 1878 to examine the mouth of the Saint John's River, and to report on the practicability of deepening the channel through the bar with jetties. He went there, and, after a personal examination, presented a very elaborate report. In 1880 the governor of California had requested him to act as consulting engineer of that State, and he accordingly visited the Sacramento River, and reported upon the plans for the preservation of its channel and the arrest of debris from the mines. In 1881 he was consulted by the Canadian Minister of Public Works on the improvement of the harbor of Toronto, which he also examined. This was the first instance in which the Canadian government had ever employed an American engineer. When he was in Mexico, the government there asked him for reports on the harbors of Vera Cruz and Tampico and suggestions for their improvement. Although he did not examine these two harbors personally, he drew up plans on surveys furnished by engineers whom he sent there; and the work which has since been carried out after his instructions has proved eminently satisfactory. Again, it was the people of Vicksburg who sent for him to tell them how to better their harbor; and at another time he was consulted about the Columbia River in Oregon and about Humboldt Bay. In 1885 the Brazilian Emperor made a second attempt to secure his services for an examination of the Rio Grande del Sul, but ill health and pressing business prevented his acceptance of the offer; nor was he able to undertake the examination of the harbor of Oporto requested by the Portuguese government. It seems superfluous to say that all the reports he did make "were exhaustive and eminently instructive in their treatment of the subjects discussed." Perhaps the two most important professional cases submitted to him were those in 1884 on the estuary and bar of the Mersey River and on Galveston Harbor. In the case of the Mersey he was called in, at the solicitation of the Mersey Docks and Harbor Board of Liverpool, to settle a dispute. Appearing before a committee of the House of Lords, he gave his testimony as to the effect which the proposed terminal works of the Manchester ship canal would have upon the estuary of the Mersey and the bar at Liverpool. "He brought to the solution of this question that same keen insight into hydraulics and the same close application that had made him so successful in this country." He showed so plainly what would inevitably be the deleterious results of the proposed plans that the committee decided against them. Subsequently they were changed to conform to his suggestions. For this report he received L3500, said to have been the largest fee ever paid to a consulting engineer.
