Lance-corporal William Greenhill was attached to Lieutenant Murphy, R.E., and his duties were those which arose out of surveying and astronomy. In the whole of the survey of the two rivers and the countries adjacent to their banks, he took an important part, and after the death of that officer was employed on the line of levels between the two rivers, with reference to a canal of intercommunication for commercial purposes. Captain Estcourt, 43rd regiment, the second in command, in writing of this non-commissioned officer, says: “A more willing, honest, active man does not exist, and he is sober and trustworthy in the highest degree.” “All,” writes the same officer, “are valuable men, and capable of rendering important services wherever they may be employed.” The approbation of the commissioners for the affairs of India was accompanied with the following gratuities:—to corporal Black 39_l._, and to each of the other three non-commissioned officers 19_l._ 10_s._; and further, Sir Hussey Vivian, the Master-General ordered the promotion of corporal Black to the rank of sergeant, second-corporal Fisher to corporal;[298] and lance-corporal William Greenhill to be second-corporal.[299] In May the operations for the triangulation of the west coast of Scotland were resumed, for the third time, under Captain Henderson, R.E., by six non-commissioned officers and men of the corps, who were continued on the service till the early winter. They then returned to Woolwich with a good character for activity and exertion. ----- Footnote 298: Pensioned in May, 1843, and appointed assistant lighthouse keeper at Europa Point, Gibraltar, under the Trinity Board of London. ----- Footnote 299:
