In August, 1794, my father made a trial of his telegraph between Pakenham Hall and Edgeworth Town, a distance of twelve miles. He found it to succeed beyond his expectations; and in November following he made another trial of it at Collon, at Mr. Foster's, in the county of Louth. The telegraphs were on two hills, at fifteen miles' distance from each other. A communication of intelligence was made, and an answer received, in the space of five minutes. Mr. Foster--my father's friend, and the friend of everything useful to Ireland--was well convinced of the advantage and security this country would derive from a system of quick and certain communication; and, being satisfied of the sufficiency of this telegraph, advised that a memorial on the subject should be drawn up for Government. Accordingly, under his auspices, a memorial was presented, in 1795, to Lord Camden, then Lord Lieutenant. His Excellency glanced his eye over the paper, and said that he did not think such an establishment necessary, but desired to reserve the matter for further consideration. My father waited in Dublin for some time. The suspense and doubt in which courtiers are obliged to live is very different from that state of philosophical doubt which the wise recommend, and to which they are willing to submit. My father's patience was soon exhausted. The county in which he resided was then in a disturbed state; and he was eager to return to his family, who required his protection. Besides, to state things exactly as they were, his was not the sort of temper suited to attendance upon the great. The disturbances in the County of Longford were quieted for a time by the military; but again, in the autumn of the ensuing year (September, 1796), rumors of an invasion prevailed, and spread with redoubled force through Ireland, disturbing commerce, and alarming all ranks of well-disposed subjects. My father wrote to Lord Carhampton, then Commander-in-Chief, and to Mr. Pelham (now Lord Chichester), who was then Secretary in Ireland, offering his services. The Secretary requested Mr. Edgeworth would furnish him with a memorial. Aware of the natural antipathy that public men feel at the sight of long memorials, this was made short enough to give it a chance of being read. (Presented, Oct. 6, 1796.) Mr. Edgeworth will undertake to convey intelligence from Dublin to Cork, and back to Dublin, by means of fourteen or fifteen different stations, at the rate of one hundred pounds per annum for each station, as long as Government shall think proper; and from Dublin to any other place, at the same rate, in proportion to the distance: provided that when Government chooses to discontinue the business, they shall pay one year's contract over and above the current expense, as some compensation for the prime cost of the apparatus, and the trouble of the first establishment.
