during the voyage of four months; on its return to Portsmouth on

March 26th; 1762; it was found (after allowing for the rate of

gain or loss) to have erred only one minute fifty…four and a half

seconds。  In the latitude of Portsmouth this only amounted to

eighteen geographical miles; whereas the Act had awarded that the

prize should be given where the longitude was determined within

the distance of thirty geographical miles。  One would have

thought that Harrison was now clearly entitled to his reward of

20;000L。



Not at all!  The delays interposed by Government are long and

tedious; and sometimes insufferable。  Harrison had accomplished

more than was needful to obtain the highest reward which the

Board of Longitude had publicly offered。  But they would not

certify that he had won the prize。  On the contrary; they started

numerous objections; and continued for years to subject him to

vexatious delays and disappointments。  They pleaded that the

previous determination of the longitude of Jamaica by

astronomical observation was unsatisfactory; that there was no

proof of the chronometer having maintained a uniform rate during

the voyage; and on the 17th of August; 1762; they passed a

resolution; stating that they 〃were of opinion that the

experiments made of the watch had not been sufficient to

determine the longitude at sea。〃



It was accordingly necessary for Harrison to petition Parliament

on the subject。  Three reigns had come and gone since the Act of

Parliament offering the reward had been passed。  Anne had died;

George I。 and George II。 had reigned and died; and now; in the

reign of George III。thirty…five years after Harrison had begun

his labours; and after he had constructed four several marine

chronometers; each of which was entitled to win the full

prize;an Act of Parliament was passed enabling the inventor to

obtain the sum of 5000L。 as part of the reward。  But the

Commissioners still hesitated。  They differed about the tempering

of the springs。  They must have another trial of the timekeeper;

or anything with which to put off a settlement of the claim。 

Harrison was ready for any further number of trials; and in the

meantime the Commissioners merely paid him a further sum on

account。



Two more dreary years passed。  Nothing was done in 1763 except a

quantity of interminable talk at the Board of Commissioners。  At

length; on the 28th of March; 1764; Harrison's son again departed

with the timekeeper on board the ship Tartar for Barbadoes。  He

returned in about four months; during which time the instrument

enabled the longitude to be ascertained within ten miles; or

one…third of the required geographical distance。  Harrison

memorialised the Commissioners again and again; in order that he

might obtain the reward publicly offered by the Government。



At length the Commissioners could no longer conceal the truth。 

In September;1764; they virtually recognised Harrison's claim by

paying him 1000L。 on account; and; on the 9th of February;1765;

they passed a resolution setting forth that they were

〃unanimously of opinion that the said timekeeper has kept its

time with sufficient correctness; without losing its longitude in

the voyage from Portsmouth to Barbadoes beyond the nearest limit

required by the Act l2th of Queen Anne; but even considerably

within the same。〃  Yet they would not give Harrison the necessary

certificate; though they were of opinion that he was entitled to

be paid the full reward!



It is pleasant to contrast the generous conduct of the King of

Sardinia with the procrastinating and illiberal spirit which

Harrison met with in his own country。  During the same year in

which the above resolution was passed; the Sardinian minister

ordered four of Harrison's timekeepers at the price of 1000L。 

each; at the special instance of the King of Sardinia 〃as an

acknowledgement of Mr。 Harrison's ingenuity; and as some

recompense for the time spent by him for the general good of

mankind。〃  This grateful attention was all the more praiseworthy;

as Sardinia could not in any way be regarded as a great maritime

power。



Harrison was now becoming old and feeble。  He had attained the

age of seventy…four。  He had spent forty long years in working

out his invention。  He was losing his eyesight; and could not

afford to wait much longer。  Still he had to wait。



〃Full little knowest thou; who hast not tried; 

What hell it is in suing long to bide; 

To lose good days; that might be better spent; 

To waste long nights in pensive discontent; 

To spend to…day; to be put back to…morrow; 

To feed on hope; to pine with fear and sorrow。〃



But Harrison had not lost his spirit。  On May 30th; 1765; he

addressed another remonstrance to the Board; containing much

stronger language than he had yet used。  〃I cannot help

thinking;〃 he said; 〃that I am extremely ill…used by gentlemen

from whom I might have expected a different treatment; for; if

the Act of the l2th of Queen Anne be deficient; why have I so

long been encouraged under it; in order to bring my invention to

perfection?  And; after the completion; why was my son sent twice

to the West Indies?  Had it been said to my son; when he received

the last instruction; 'There will; in case you succeed; be a new

Act on your return; in order to lay you under new restrictions;

which were not thought of in the Act of the l2th of Queen Anne;'

I say; had this been the case; I might have expected some such

treatment as that I now meet with。



〃It must be owned that my case is very hard; but I hope I am the

first; and for my country's sake I hope I shall be the last; to

suffer by pinning my faith upon an English Act of Parliament。 

Had I received my just rewardfor certainly it may be so called

after forty years' close application of the talent which it has

pleased God to give methen my invention would have taken the

course which all improvements in this world do; that is; I must

have instructed workmen in its principles and execution; which I

should have been glad of an opportunity of doing。  But how widely

different this is from what is now proposed; viz。; for me to

instruct people that I know nothing of; and such as may know

nothing of mechanics; and; if I do not make them understand to

their satisfaction; I may then have nothing!



〃Hard fate indeed to me; but still harder to the world; which may

be deprived of this my invention; which must be the case; except

by my open and free manner in describing all the principles of it

to gentlemen and noblemen who almost at all times have had free

recourse to my instruments。  And if any of these workmen have

been so ingenious as to have got my invention; how far you may

please to reward them for their piracy must be left for you to

determine; and I must set myself down in old age; and thank God I

can be more easy in that I have the conquest; and though I have

no reward; than if I had come short of the matter and by some

delusion had the reward!〃



The Right Honourable the Earl of Egmont was in the chair of the

Board of Longitude on the day when this letter was readJune 13;

1765。  The Commissioners were somewhat startled by the tone which

the inventor had taken。  Indeed; they were rather angry。  Mr。

Harrison; who was in waiting; was called in。  After some rather

hot speaking; and after a proposal was made to Harrison which he

said he would decline to accede to 〃so long as a drop of English

blood remained in his body;〃 he left the room。  Matters were at

length arranged。  The Act of Parliament (5 Geo。 III。 cap。 20)

awarded him; upon a full discovery of the principles of his

time…keeper; the payment of such a sum; as with the 2500L。 he had

already received; would make one half of the reward; and the

remaining half was to be paid when other chronometers had been

made after his design; and their capabilities fully proved。  He

was also required to assign his four chronometersone of which

was styled a watchto the use of the public。



Harrison at once proceeded to give full explanations of the

principles of his chronometer to Dr。 Maskelyne; and six other

gentlemen; who had been appointed to receive them。  He took his

timekeeper to pieces in their presence; and deposited in their

hands correct drawings of the same; with the parts; so that other

skilful makers might construct similar chronometers on the same

principles。  Indeed; there was no difficulty in making them;

after his explanations and drawings had been published。  An exact

copy of his last watch was made by the ingenious Mr。 Kendal; and

was used by Captain Cook in his three years' circumnavigation of

the world; to his perfect satisfaction。



England had already inaugurated that series of scientific

expeditions which were to prove so fruitful of results; and to

raise her naval reputation to so great a height。  In these

expeditions; the officers; the sailors; and th
