"So much for Mr. Edgeworth from my point of view," concluded the Colonel. "You will hear what he thought of himself from Bedford."
EDGEWORTH"S TELEGRAPH.
[DESCRIBED BY HIMSELF.]
Bets of a rash or ingenious sort were in fashion in those days, and one proposal of what was difficult and uncommon led to another. A famous match was at that time pending at Newmarket between two horses that were in every respect as nearly equal as possible. Lord March, one evening at Ranelagh, expressed his regret to Sir Francis Delaval that he was not able to attend Newmarket at the next meeting. "I am obliged," said he, "to stay in London. I shall, however, be at the Turf Coffee House. I shall station fleet horses on the road to bring me the earliest intelligence of the event of the race, and shall manage my bets accordingly."
I asked at what time in the evening he expected to know who was winner.
He said about nine in the evening. I a.s.serted that I should be able to name the winning horse at four o"clock in the afternoon. Lord March heard my a.s.sertion with so much incredulity as to urge me to defend myself; and at length I offered to lay five hundred pounds, that I would in London name the winning horse at Newmarket at five o"clock in the evening of the day when the great match in question was to be run. Sir Francis, having looked at me for encouragement, offered to lay five hundred pounds on my side; Lord Eglintoun did the same; Shaftoe and somebody else took up their bets; and the next day we were to meet at the Turf Coffee House, to put our bets in writing. After we went home, I explained to Sir Francis Delaval the means that I proposed to use. I had early been acquainted with Wilkins"s "Secret and Swift Messenger;" I had also read in Hooke"s Works of a scheme of this sort, and I had determined to employ a telegraph nearly resembling that which I have since published. The machinery I knew could be prepared in a few days.
Sir Francis immediately perceived the feasibility of my scheme, and indeed its certainty of success. It was summer-time; and by employing a sufficient number of persons, we could place our machines so near as to be almost out of the power of the weather. When we all met at the Turf Coffee House, I offered to double my bet; so did Sir Francis. The gentlemen on the opposite side were willing to accept my offer; but before I would conclude my wager, I thought it fair to state to Lord March that I did not depend upon the fleetness or strength of horses to carry the desired intelligence, but upon other means, which I had, of being informed in London which horse had actually won at Newmarket, between the time when the race should be concluded and five o "clock in the evening. My opponents thanked me for my candor and declined the bet.
My friends blamed me extremely for giving up such an advantageous speculation. None of them, except Sir Francis, knew the means which I had intended to employ; and he kept them a profound secret, with a view to use them afterwards for his own purposes. With that energy which characterized everything in which he engaged, he immediately erected, under my directions, an apparatus between his house and part of Piccadilly,--an apparatus which was never suspected to be telegraphic.
I also set up a night telegraph between a house which Sir F. Delaval occupied at Hampstead, and one to which I had access in Great Russell Street, Bloomsbury. This nocturnal telegraph answered well, but was too expensive for common use.
Upon my return home to Hare Hatch, I tried many experiments on different modes of telegraphic communication. My object was to combine secrecy with expedition. For this purpose I intended to employ windmills, which might be erected for common economical uses, and which might at the same time afford easy means of communication from place to place upon extraordinary occasions. There is a windmill at Nettlebed, which can be distinctly seen with a good gla.s.s from a.s.sy Hill, between Maidenhead and Henly, the highest ground in England south of the Trent. With the a.s.sistance of Mr. Perrot, of Hare Hatch, I ascertained the practicability of my scheme between these places, which are nearly sixteen miles asunder.
I have had occasion to show my claim to the revival of this invention in modern times, and in particular to prove that I had practised telegraphic communication in the year 1767, long before it was ever attempted in France. To establish these truths, I obtained from Mr.
Perrot, a Berkshire gentleman, who resided in the neighborhood of Hare Hatch, and who was witness to my experiments, his testimony to the facts which I have just related. I have his letter; and before its contents were published in the Memoirs of the Irish Academy for the year 1796, I showed it to Lord Charlemont, President of the Royal Irish Academy.
MR. EDGEWORTH"S TELEGRAPH IN IRELAND.
[DESCRIBED BY HIS DAUGHTER.]
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 s.p.a.ce 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.
In a letter of a single page, accompanying this memorial, it was stated, that to establish a telegraphic corps of men sufficient to convey intelligence to every part of the kingdom where it should be necessary, stations tenable against a mob and against musketry might be effected for the sum of _six or seven thousand pounds_. It was further observed, that of course there must be a considerable difference between a partial and a general plan of telegraphic communication; that Mr. Edgeworth was perfectly willing to pursue either, or to adopt without reserve any better plan that Government should approve. Thanks were returned, and approbation expressed.
Nothing now appeared in suspense except the _mode_ of the establishment, whether it should be civil or military. Meantime Mr. Pelham spoke of the Duke of York"s wish to have a reconnoitring telegraph, and observed that Mr. Edgeworth"s would be exactly what his Royal Highness wanted. Mr.
Edgeworth in a few days constructed a portable telegraph, and offered it to Mr. Pelham. He accepted it, and at his request my brother Lovell carried it to England, and presented it to the Duke from Mr. Pelham.
During the interval of my brother"s absence in England, my father had no doubt that arrangements were making for a telegraphic establishment in Ireland. But the next time he went to the castle, he saw signs of a change in the Secretary"s countenance, who seemed much hurried,--promised he would write,--wrote, and conveyed, in diplomatic form, a final refusal. Mr. Pelham indeed endeavored to make it as civil as he could, concluding his letter with these words:--
The utility of a telegraph may hereafter be considered greater; but I trust that at all events those talents which have been directed to this pursuit will be turned to some other object, and that the public will have the benefit of that extraordinary activity and zeal which I have witnessed on this occasion in some other inst.i.tution which I am sure that the ingenuity of the author will not require much time to suggest.
I have the honor to be, with great respect, &c,
T. PELHAM.
DUBLIN CASTLE, Nov. 17, 1796.
Of his offer to establish a communication from the coast of Cork to Dublin, at _his own expense_, no notice was taken. "He had, as was known to Government, expended 500 of his own money; as much more would have erected a temporary establishment for a year to Cork. Thus the utility of this invention might have been tried, and the most prudent government upon earth could not have accused itself of extravagance in being partner with a private gentleman in an experiment which had, with inferior apparatus, and at four times the expense, been tried in France and England, and approved." The most favorable supposition by which we can account for the conduct of the Irish Government in this business is that a superior influence in England forbade them to proceed. "It must,"
said my father, "be mortifying to a viceroy who comes over to Ireland with enlarged views and benevolent intentions, to discover, when he attempts to act for himself, that he is peremptorily checked; that a circle is chalked round him, beyond which he cannot move."
No personal feelings of pique or disgust prevented my father from renewing his efforts to be of service to his country. Two months after the rejection of his telegraph, on Friday the 30th of December, 1796, the French were on the Irish coasts. Of this he received intelligence late at night. Immediately he sent a servant express to the Secretary, with a letter offering to erect telegraphs, which he had in Dublin, on any line that Government should direct, and proposing to bring his own men with him; or to join the army with his portable telegraphs, to reconnoitre. His servant was sent back with a note from the Secretary, containing compliments and the promise of a speedy answer; no further answer ever reached him. Upon this emergency he could, with the a.s.sistance of his friends, have established an immediate communication between Dublin and the coast, which should not have cost the country one shilling. My father showed no mortification at the neglect with which he was treated, but acknowledged that he felt much "concern in losing an opportunity of saving an enormous expense to the public, and of alleviating the anxiety and distress of thousands." A telegraph was most earnestly wished for at this time by the best-informed people in Ireland, as well as by those whose perceptions had suddenly quickened at the view of immediate danger. Great distress, bankruptcies, and ruin to many families, were the consequences of this attempted invasion. The troops were hara.s.sed with contrary orders and forced marches, for want of intelligence, and from that indecision which must always be the consequence of insufficient information. Many days were spent in terror and in fruitless wishes for the English fleet. One fact may mark the hurry and confusion of the time; the cannon and the ball sent to Bantry Bay were of different calibre. At last Ireland was providentially saved by the change of wind, which prevented the enemy from effecting a landing on her coast.
That the public will feel little interest in the danger of an invasion of Ireland which might have happened in the last century; that it can be of little consequence to the public to hear how or why, twenty years ago, this or that man"s telegraph was not established,--I am aware; and I am sensible that few will care how cheaply it might have been obtained, or will be greatly interested in hearing of generous offers which were not accepted, and patriotic exertions which were not permitted to be of any national utility. I know that as a biographer I am expected to put private feelings out of the question; and this duty, as far as human nature will permit, I hope I have performed.
The facts are stated from my own knowledge, and from a more detailed account in his own "Letter to Lord Charlemont on the Telegraph,"--a political pamphlet, uncommon at least for its temperate and good-humored tone.
Though all his exertions to establish a telegraph in Ireland were at this time unsuccessful, yet he persevered in the belief that in future modes of telegraphic communication would be generally adopted; and instead of his hopes being depressed, they were raised and expanded by new consideration of the subject in a scientific light. In the sixth volume of the "Transactions of the Royal Irish Academy," he published an "Essay on the Art of Conveying Swift and Secret Intelligence," in which he gives a comprehensive view of the uses to which the system may be applied, and a description, with plates, of his own machinery. Accounts of his apparatus and specimens of his vocabulary have been copied into various popular publications, therefore it is sufficient here to refer to them. The peculiar advantages of his machinery consist, in the first place, in being as free from friction as possible, consequently in its being easily moved, and not easily destroyed by use; in the next place, on its being simple, consequently easy to make and to repair. The superior advantage of his vocabulary arises from its being undecipherable. This depends on his employing the numerical figures instead of the alphabet. With a power of almost infinite change, and consequently with defiance of detection, he applies the combination of numerical figures to the words of a common dictionary, or to any length of phrase in any given vocabulary. He was the first who made this application of figures to telegraphic communication.
Much has been urged by various modern claimants for the honor of the invention of the telegraph. In England the claims of Dr. Hooke and of the Marquis of Worcester to the original idea are incontestable. But the invention long lay dormant, till wakened into active service by the French. Long before the French telegraph appeared, my father had tried his first telegraphic experiments. As he mentions in his own narrative, he tried the use of windmill sails in 1767 in Berkshire; and also a nocturnal telegraph with lamps and illuminated letters, between London and Hampstead. He refers for the confirmation of the facts to a letter of Mr. Perrot"s, a Berkshire gentleman who was with him at the time. The original of this letter is now in my possession. It was shown in 1795 to the President of the Royal Irish Academy. The following is a copy of it:--
DEAR SIR,--I perfectly recollect having several conversations with you in 1767 on the subject of a speedy and secret conveyance of intelligence. I recollect your going up the hills to see how far and how distinctly the arms (and the position of them) of Nettlebed Windmill sails were to be discovered with ease.
As to the experiments from Highgate to London by means of lamps, I was not present at the time, but I remember your mentioning the circ.u.mstance to me in the same year. All these particulars were brought very strongly to my memory when the French, some years ago, conveyed intelligence by signals; and I then thought and declared that the merit of the invention undoubtedly belonged to you. I am very glad that I have it in my power to send you this confirmation, because I imagine there is no other person now living who can bear witness to your observations in Berkshire.
I remain, dear Sir,
Your affectionate friend, JAMES L. PERROT.
BATH, Dec. 9, 1795.
Claims of priority of invention are always listened to with doubt, or, at best, with impatience. To those who bring the invention to perfection, who actually adapt it to use, mankind are justly most grateful, and to these, rather than to the original inventors, grant the honors of a triumph. Sensible of this, the matter is urged no farther, but left to the justice of posterity.
I am happy to state, however, one plain fact, which stands independent of all controversy, that my father"s was the _first_, and I believe the only, telegraph which ever spoke across the Channel from Ireland to Scotland. He was, as he says in his essay on this subject, "ambitious of being the first person who should connect the islands more closely by facilitating their mutual intercourse;" and on the 24th of August, 1794, my brothers had the satisfaction of sending by my father"s telegraph four messages across the Channel, and of receiving immediate answers, before a vast concourse of spectators.
_Edgeworth to Dr. Darwin._
EDGEWORTHTOWN, Dec. 11, 1794.
I have been employed for two months in experiments upon a telegraph of my own invention. I tried it partially twenty-six years ago. It differs from the French in distinctness and expedition, as the intelligence is not conveyed alphabetically....
I intended to detail my telegraphs (in the plural), but I find that I have not room at present. If you think it worth while, you shall have the whole scheme before you, which I know you will improve for me.
Suffice it, that by day, at eighteen or twenty miles" distance, I show, by four pointers, isosceles triangles, twenty feet high, on four imaginary circles, eight imaginary points, which correspond with the figures
0, 1, 2, 3, 4, 5, 6, 7.
So that seven thousand different combinations are formed, of four figures each, which refer to a dictionary of words that are referred to,--of lists of the navy, army, militia, lords, commons, geographical and technical terms, &c, besides an alphabet. So that everything one wishes may be transmitted with expedition.
By night, white lights are used.
