CHAPTER XXI.

ENGINES FOR SOUTH AMERICA.

[Rough draft.]

"SIR, "CAMBORNE, _May 20th, 1813_.

"Yours of the 7th inst. I should have answered by return, as

requested; but an unexpected circumstance prevented my being at

Swansea as early as proposed, which, as it happens, best suits your

purpose as well as my own. I shall not be able to be there within

twenty days from this time, of which I will give you timely notice. I

hope before that time Mrs. Rastrick will be safe out of the straw. I

have been detained in consequence of a strange gentleman calling on

me, who arrived at Falmouth about ten days since, from Lima, in South

America, for the sole purpose of taking out steam-engines, pumps, and

sundry other mining materials to the gold and silver mines of Mexico

and Peru. He was recommended to me to furnish him with mining utensils

and mining information. He was six months on his passage, which did

not agree with his health, and has kept his bed ever since he came on

shore; but is now much recovered, and hopes to be able to go down in

the Cornish mines with me in a few days. I have already an order from

him for six engines, which is but a very small part of what he wants.

I am making drawings for you, and intend to be with you as soon as

they are finished. Money is very plentiful with him, and if you will

engage to finish a certain quantity of work by a given time, you may

have the money before you begin the job. The West India engine will

suit his purpose. I shall have a great deal of business to do with you

when we meet. In the meantime please to forward the thrashing engines

to Cornwall as quickly as possible. The engine for Plymouth will be

put to break the ground as soon as I can find time to go up there.

Please to say when and by what ship I shall have the small engines.

"I remain, Sir,

"Your very obedient servant,

"R. T.

"To MR. JOHN U. RASTRICK,

"_Bridgenorth, Shropshire._

"The copper mine mentioned in my last is improving very fast."

The strange gentleman referred to was Don Francisco Uville, a person of

great influence in Lima, who a year or two before had travelled from

Peru to England and back, in search of steam-engines to pump water from

the ancient gold and silver mines then flooded and idle. Boulton and

Watt, at Soho, on being consulted, discouraged the attempt, because of

the difficulty of conveying heavy machinery over mountain pathways, and

also because their low-pressure vacuum engine, using steam but slightly

above atmospheric pressure, would be much less effective in the

comparatively light atmosphere on the high summits of the Cordillera

Mountains than in England. Uville, who had heard of the wonderful

ability of English engineers to construct steam pumping engines, was

utterly downhearted at this decision of the great Soho engineers, and

while dejectedly wandering through the streets of London, unconsciously

gazed into the shop window of Mr. Roland in Fitzroy Square, near the

spot on which Trevithick had run his railway locomotive three years

before.[120] Rumour of passed events may have led him to visit the ground

on which had worked a new kind of steam-engine. His searching glance

discovered among numerous articles for sale, an unknown form that might

be the talisman he had travelled thousands of miles in search of. The

shopkeeper informed him that it was a model of Richard Trevithick's

high-pressure steam-engine, which worked without condensing water,

or vacuum. If what he heard was true, why should it not work equally

well in the light atmosphere of the mines? The great engineer at Soho

might be in error or ignorance. The experiment, as a last resource, was

worth making. He would pay the 20_l._ for the model, carry it to the

mines of Cerro de Pasco, in the high mountains above Lima, where, if it

worked as well as it did in London, the rich mines of Peru would again

reveal their long-hidden treasure. The model was conveyed by ship to

Lima, and then on a mule up the narrow precipitous ascents to Cerro de

Pasco, over mountains more than 20,000 feet high. Fire was placed in

the small boiler as he had seen it done in London, and with the same

result, to the great joy of Uville, who determined to revisit England

in search of the inventor of this new and wonderful power. On his

return voyage, when rounding Cape Horn, bets were made on the chances

of his finding the man who had invented the high-pressure steam-puffer

engine,[121] and of his being able to persuade such a person to make the

required engines and accompany them to Peru. Such gloomy forebodings

ended in an attack of brain fever. The vessel touched at Jamaica,

where Uville was landed. On recovering health and strength he embarked

for England in one of the packet-ships, and during the voyage still

spoke of the object of his search. A fellow-traveller, called Captain

Teague, rejoiced him by saying, "I know all about it; it is the easiest

thing in the world. The inventor of your high-pressure steam-engine

is a cousin of mine, living within a few miles of Falmouth, the port

we are bound for." On landing, Uville, still weak and obliged to keep

his bed, was told that Trevithick, the engineer, lived in London, and

was constructing the Thames Tunnel; but further inquiry showed that he

also had suffered from brain fever, and had just returned to Penponds,

only a few miles from Falmouth. On the 10th of May, 1813, a letter

reached Trevithick, requesting him to visit the sick Uville, and in a

fortnight from that time the engineer had mastered the requirements

of the Peruvian mines, and had designed and made arrangements for the

supply of six pumping engines, together with the pumps and all things

necessary for the underground workings; the whole to be delivered in

four months.

"SIR, "CAMBORNE, _May 22nd, 1813_.

"I have engaged to get six engines, with pit-work, &c., to send

abroad. A great part of the wrought-iron work and the boilers I have

arranged for in Cornwall. These engines will be high-pressure engines,

because the place they are for has a very deep adit driven into the

mountain; and lifting condensing water to the surface would be a

greater load than the whole of the work under the adit level.

"I call a set of work, a 24-inch cylinder single engine, 6-feet

stroke, piston, cylinder bottom, single nozzle, with two 5-inch valves

and perpendicular pipe; no cylinder top; the piston-rod not to be

turned; 3-inch safety-valve, fire-door, two small Y[**symbol] shafts

and gear-handles, &c.; a good strong winch set in a broadish frame,

such as is often used on quays or in quarries, 25 fathoms of 12-inch

pumps, a 12-inch plunger, an 11-inch working barrel, clack-seat and

wind-bore, with brass boshes and clacks, a force-pump for the boiler,

and 10 fathoms of 3-inch pipes to carry the water to and from the

engines. I have engaged to supply six full sets of the above-mentioned

materials.

"All these castings must be delivered in Cornwall in four months from

the time the orders are given; therefore, if you take the job, or any

part of it, you must enter into an engagement to fulfil it in the

time. As there ought not to be a moment lost, I wish you to answer me

immediately in what time you will deliver those materials in Cornwall;

or otherways, what part of them you can execute in the time.

"I am making the drawing, which will be ready before I can receive

your answer. For whatever part of the job you may engage I will lodge

the money to pay for the whole in Mr. Fox's hands, which will then

be paid for before you begin the work, as soon as you execute the

agreement.

"R. T.

"MR. PENGILLY, _Neath Abbey, South Wales_."

It is an odd coincidence that while writing of the events of

fifty-eight years ago, pumping engines are being sent to those same

mines with the steam-cylinder in twenty-two pieces, no piece to weigh

more than 300 lbs.--a facility in mechanical arrangements not enjoyed

by Trevithick--having Trevithick's high-pressure boilers, giving steam

of 50 lbs. on the inch.[122]

[Footnote 122: Made by Harvey and Co., Hayle, 1870.]

[Rough draft.]

"SIR. "CAMBORNE, _June 2nd, 1813_.

"I drop you this note just to inform you that I have begun your job.

Yesterday I engaged a great many smiths and boiler-builders, who set

to work this morning. I have also engaged all the boiler-plates in

the county, which will be sent to-day to the different workmen. The

master-smiths that I have engaged are the best in the kingdom. I have

obligated them to put the best quality of iron, and to be delivered

at Falmouth within four months. I have been obliged to give them a

greater price than I expected, otherwise they would not turn aside

their usual business employment for a short job of four months.

"Mr. Teague is with me, and one other, assisting about the drawings.

If you call at Camborne about Friday, shall be able to show you

the designs. The drawings for the castings will be sent to the

iron-founders by the end of this week; and by the end of next week

shall have the whole of the different tradesmen in full employ. If

you wish to have a greater quantity of machinery ready by the end of

September, there ought to be as little time as possible lost in giving

your orders. I can get you double the quantity, provided you give the

orders in time.

"As soon as it is convenient to you to arrange the payments I would

thank you to inform me, because we find in practice that the best way

to make a labouring machine turn quickly on its centres, is to keep

them well oiled.

"R. T.

"F. UVILLE, Esq., MR. HOOPER'S, _Falmouth_.

"N.B.--If you intend to be at Camborne, please to drop me a note by

post, and I will be at home."

In all Trevithick's moves there was a scramble for money, in which

he invariably came worst off. He could give a good hint that working

centres would not turn well without the essential oil; but he failed

to apply the principle to himself. Liberal words and golden prospects

carried him off at once; and before Uville was strong enough to visit

the Cornish mines and to fully explain what he wanted, the machinery

was being made, though at that same time the thrashing and ploughing

engines, and the locomotive and rock-boring engine, and the great fight

with Watt at Dolcoath, were in progress.

[Rough draft.]

"MR. RASTRICK, "CAMBORNE, _June 8th, 1813_.

"Sir,--Enclosed I send to you a drawing for a set of pumps for one

of the engines for South America, with a drawing for a part of the

castings for one of the boilers, for you to make a beginning. The

drawings for the engines I will send in a few days. The Spanish

gentleman who is now gone to London to arrange his money concerns,

will be down again in about ten or twelve days, and then we shall both

call at Bridgenorth, and bring with us the engagement for you to sign,

for the performance of such quantities of work as you can execute in

four months.

"I have made arrangements with the smiths and boiler-*builders here,

to weigh and pay at the end of every week. The regulation of your

payment is left to you to point out in any way you please. As time is

of the greatest consequence, I hope you will set to work immediately.

"The reason for making the pumps so short, is on account of the

extreme badness of the roads over the mountains, where these engines

are to be conveyed, it being almost impossible to carry above five

hundredweight in one piece. The West India engine is sold to send to

Lima, but not to be conveyed over the mountains. I shall also bring

drawings with me for one or two winding engines for the same place.

Please write to me by return of post.

"R. T."

"CAMBORNE, near TRURO, _June 11th, 1813_.

"MR. FRANCIS UVILLE,

"at MESSRS. CAMPBELL AND CO.'S, London.

"Sir,--I have your favour of the 9th instant, respecting the weight

of the largest parts of the engines. I will take care to reduce the

weight if possible, so as to be carried on the backs of mules.

"By the time I receive your letter I shall have arranged the whole

of the engine business, and intend to go immediately to Wales and

Shropshire, to get the engagements executed for the performance of the

work by the time proposed. I shall write to you again before I leave

home, and as soon as I arrive in Wales will also write to you. I shall

not stay in Wales above two days, but go to Bridgenorth in Shropshire,

where I hope to have the pleasure of meeting you, as it will only be

about twelve hours' ride out of your road to Cornwall.

"In the North I shall introduce you to the sight of a great deal of

mining and machinery, and in about ten days from the time you arrive

at Bridgenorth, shall be able to accomplish the business so as to

return again to Cornwall.

"I would thank you to inform me as early as you can, of the number

of engines you intend to get executed by the proposed time, because

when I am in the North I shall be able to arrange with the founders

accordingly. The smiths are all at work for you.

"R. T."

[Rough draft.]

"MR. UVILLE, "CORNWALL, CAMBORNE, _June 19th, 1813_.

"Sir,--Your favour of the 9th instant, dated from Falmouth, I

received, and in return wrote to you immediately--directed for you at

Messrs. Campbell and Co.'s, London. As you said in your last letter,

that immediately on your arrival in town you would write to me, I have

expected every post since last Tuesday would have brought me a letter;

but as I have not received it according to your promise, I am fearful

that your letter may be unexpectedly detained, especially as you told

me the last time I saw you at Falmouth, that you would enclose me

a bank post bill. All the founders and other tradesmen are in full

employ on your engines.

"I intended to have left Cornwall for Wales and Shropshire by

this time, with the founders' articles for execution; but being

disappointed in not hearing from you, agreeable to our appointment, I

shall delay it until I hear from you, which I must request you to have

the goodness to do by return of post, because those delays make very

much against the execution of your work; and as time is of so great

a consequence to you, I hope you will not lose a moment in writing

and giving me the necessary instructions, with a few drops of that

essential oil that you proposed sending me on your arrival in town.

"R. T."

The sugar rolling-mill engine that had been made for the West Indies

so pleased Uville that he purchased it at once, intending it for the

Mint at Lima. He also ordered one or two winding engines, in addition

to the pumping engines. Trevithick had arranged that no piece should

exceed 560 lbs. in weight. Then came Uville's order, "if possible to

be reduced so as to be carried on the backs of mules." Since that time

the path on the mountains has been improved, yet the present limit

of weight is 300 lbs. The absence of the promised bank post bill was

another difficulty.

[Rough draft.]

"CAMBORNE, _June 23rd, 1813_.

"MR. FRANCIS UVILLE,

"at MESSRS. CAMPBELL AND CO.'S, Park Buildings, London.

"Sir,--Your favour of the 19th instant came safe to hand.

"I was in hopes that I should have found a remittance enclosed. All

the tradesmen that I have employed on your work were to have been paid

every Saturday, and I made my arrangement with you accordingly. Unless

this mode of proceeding is followed up, you cannot get your work done

in any reasonable time, especially as you are an entire stranger. For

my own part I have placed the greatest confidence in your honour, with

which I am fully satisfied.

"But I have to get this work from a great number of different

tradesmen, and must make regular payments agreeable with my

engagements with them. As the articles are about to be executed by

different tradesmen, regular weekly payments ought to be established,

of which I informed you before the work began.

"I am ready for my journey to Wales and Shropshire, but cannot proceed

with further engagements until I hear again from you. I have placed

the fullest confidence in your word, a proof of which you have in the

great exertion I have made to get the work done; but unless you in

return place some confidence in me, or any other engineer that you may

employ, a work of this magnitude cannot be carried on with promptitude.

"As the whole of the work in my part has been put into immediate

operation, it would be a very serious loss both of money and time to

discharge the hands. I hope you will fully consider this business, and

must beg you will have the goodness to write to me by return of post.

On receiving the needful from you I shall leave Cornwall for Wales and

Shropshire.

"R. T."

Trevithick for once in his life was wise, and would not start on his

journey to Bridgenorth until the money had reached him. This prudent

resolve was soon forgotten in the love of making the steam-engine

useful; and as such creations in his hands grew into shape and size

before other men would have got through preliminary discussions,

pecuniary difficulties sprang up, as mushrooms do in a night.

[Rough draft.]

"CAMBORNE, _September 4th, 1813_.

"MESSRS. HAZELDINE, RASTRICK, AND CO.,

"Gentlemen,--Enclosed you have three of Mr. Uville's drafts, value one

hundred and fifty pounds.

"I should have sent it in one draft, but had not a suitable stamp. The

castings, pipes, ale, &c., arrived safely. I hope that all the boilers

and wrought-iron work will be finished by the end of this month, and

shipped off for London. Immediately after Mr. Uville and I shall leave

Cornwall for Bridgenorth on our journey to town. We are both very

anxious to see the 'Sanspareil' engine at work, and hope you will have

it ready by that time. I have received orders from different persons

since I have been here, for steam-engines for the West Indies, and

must, if possible, have three ready early in November, as the ships

sail then that will take them.

"I wish you would say in your next if this can be done in time,

because these persons are very extensive agents for the planters, and

are extremely anxious to generally adopt them in the West Indies.

"We find from your letter that you are getting on pretty fairly with

Uville's work.

"I remain,

"Your very humble servant,

"RICHARD TREVITHICK."

[Rough draft.]

"GENTLEMEN, "CAMBORNE, _September 7th, 1813_.

"After writing to you on Sunday last, Mr. Uville received letters from

Cadiz, from the Spanish Government, informing him that there was a

line-of-battle ship there that should take the engines to Lima. Now as

this ship is detained for this purpose, all possible dispatch must be

made to get the whole of the materials shipped as early as possible

for Cadiz. I am pushing the smiths as hard as possible, and you must

do the same at your works, that the greatest dispatch may be made.

I am ordered by Mr. Uville to request you to get one water-engine,

pumps, &c., complete, one winding engine, winding apparatus, &c.,

complete, and one crushing apparatus, complete, in addition to the

former order. I wish you would also get on as fast as possible with

the new engine, but do not let this engine prevent the getting forward

the work for Lima.

"I wish to have made apparatus to work expansively, and also a

temporary water-pump, to load the engine, so as to prove its duty by

the consumption of coal.

"If the jobs are not completed by our arrival, you need not expect any

rest until its completion. Your answer will oblige,

"R. T."

"MESSRS. HAZELDINE, RASTRICK, AND CO."

The money difficulty was for a time surmounted, with a prospect of

the completion and shipment of the work for London within four months

of the giving of the order; and the Spanish Government proposed that

a line-of-battle ship should take the engines to Lima from Cadiz. An

order was given for another pumping engine and another winding engine,

to be provided with gear for working expansively, and a temporary

water-pump, that in case of need the amount of work the engines could

do with a given amount of coal might be tested. A crushing machine, now

called "quartz-crusher," also formed part of this additional order.

The new engine, which he hoped they would get on with, was probably the

steam locomotive plough then being constructed at Bridgenorth.

[Rough draft.]

"GENTLEMEN, "CAMBORNE, _September 22nd, 1813_.

"I have your favour of the 14th instant, and hope to find you as

forward on your job on our arrival at Bridgenorth as you state. I

expect all the boiler and smith work will be shipped for London early

in October; we shall then leave Cornwall for your works, at which time

you will be very much annoyed with our company, unless we find your

assertions grounded on facts. Enclosed I send you Mr. Uville's draft

for 150_l._ Your receipt for the draft enclosed in my letter of the

16th instant has not yet arrived.

"I hope you will also have all the apparatus ready to try the new

engine; Mr. Uville is very anxious to take the first of these new

engines with him. When you send a receipt for the enclosed, please to

say what state of forwardness the whole of our work is in, and do not

neglect a moment to get the whole executed with all possible dispatch.

"Nothing short of a want of cast iron will confine our friend in

England one day after the end of this month.

"I am, Gentlemen,

"Your very humble servant,

"RICHARD TREVITHICK.

"MESSRS. HAZELDINE, RASTRICK, AND CO."

It seems probable that in 1813 a railway locomotive, with apparatus

for rock boring, and steam-crane, was made for South America as the

forerunner of the 'Sanspareil' of 1829.

[Rough draft.]

"GENTLEMEN, "CAMBORNE, _October 1st, 1813_.

"I received your favour of the 27th last evening, and now enclose you

another draft of Mr. Uville's for 150_l._ We shall wait impatiently

for your next letter to know when you will finish. Mind, this is

the 1st of October, and agreeable to promise the time is up. Mr.

Uville wishes you to cast sixty carriage-wheels for him, 11 inches

in diameter from out to out, and to weigh about 20 lbs.; cast them

of strong iron, and of a strong pattern, to take a 1-1/2-inch axle

by 2-1/2 inches deep in the hole; also cast four plunger-pistons 11

inches diameter to suit the 11-inch working barrels, provided it

should be used for the purpose of a plunger. They must be in every

respect the same as the 14-inch plunger-pistons, only 3 inches less in

diameter.

[Illustration]

"Soon after the receipt of your next letter you may expect to see us,

as a vessel has been engaged to take all the boilers and smith work on

board to-morrow week for London.

"I remain, Sir,

"Your humble servant,

"RICHARD TREVITHICK.

"MESSRS. HAZELDINE, RASTRICK, AND CO."

Probably those cast-iron wheels were ordered with a view to steam

locomotion in the Cordilleras. An engine is described in the invoice as

having chimney, axles, carriage-wheels, &c.

[Rough draft].

"GENTLEMEN, "CAMBORNE, _October 11th, 1813_.

"On making the drawings of the engine with the winding and crushing

apparatus, when at work I find that if there is no crank, but the

sweep rod is connected to a pin in the arm of the fly-wheel; in that

case the fly-wheel will cut off the engineer from getting at the

cock; but if the sweep is connected to a crank, then there will be

sufficient room. The copy of materials taken from your books and given

to Mr. Uville does not say in which way it was intended. I send you a

sketch how it will stand worked by a pin in the fly-wheel, and also

if worked by a crank over the cylinder, with the fly-wheel outside

the wood partition of the house. If you have cast all the parts for

the winding engine, you should try to alter it, having the fly-wheel

outside the wall of the house, and a crank for the inside end of the

shaft. The fly-wheel shaft will be nearly the same length both ways,

only it must be long enough for the fly-wheel to pass between the

wood partition and the 4-feet cog-wheel. The centre of the winding

cylinder will be 17 inches from the outside of the wood end of the

house, against which the fly-wheel ought to run. I have received

your favour of the 5th instant, and have enclosed, agreeably to your

request, a draft of Mr. Uville's for 800_l._, which will be the last

from Cornwall. All I have to say is, you have taken longer time for

the completion of your work than you first proposed, which has made

Mr. Uville apprehensive that it will be the means of his losing the

Spanish ship promised him to take the engines. He desires me to inform

you that he has complied with this advance on purpose to enable you to

push your work with the utmost exertion.

[Illustration: WINDING ENGINE FOR SOUTH AMERICA.]

"Please to inform us the precise time we must quit Cornwall for

Bridgenorth; we now wait entirely on you without any other thing to

engage us. I fear Mr. Rastrick being so much from home will impede

our job. If we miss this ship it will certainly make much against us

all, losing three or four months in getting a South Sea whaler, and

having the engine in a vessel not able to defend herself against an

enemy, and having to pay 15 or 20 per cent. insurance, and prevent our

getting other orders for another set of engines, and if taken by the

enemy perhaps altogether damn the undertaking. Therefore I would have

you to well consider the great inconveniences attending delay.

"I think I need not say much more to you on this head, as you ought to

feel more for your own interest than I can scribble to you on paper.

"Yours, &c.,

"R. TREVITHICK.

"MESSRS. HAZELDINE, RASTRICK, AND CO."

This rough hand-sketch and letter fully describing his requirements,

is an illustration of the facility with which Trevithick designed his

engines and made known his wishes to others.

[Rough draft.]

"GENTLEMEN, "CAMBORNE, _October 23rd, 1813_.

"Mr. Uville wishes everything to be sent off as soon as finished,

except the rolling engine, which is to remain until he arrives. We

intend to leave Cornwall for Bridgenorth on Monday, November 1st. You

may expect to see us three days after that date. The wheels ordered

for the carriages are to run on the ground and not on railroads. Mr.

Uville now wishes to have seventy-two instead of sixty as ordered

before.

"I remain, Gentlemen,

"Yours, &c.,

"R. TREVITHICK.

"MESSRS. HAZELDINE AND CO."

The last-named engine was intended for the coinage operations in the

Mint at Lima. The use of railway locomotion had been under discussion

with the engine builders, and probably those particular carriage-wheels

were ordered in the hope that the portable engine built for conveying

itself from place to place in the sugar plantations of Jamaica, would

in the Cordilleras be made to draw waggons on common roads.

The hand sketch of the winding engine in the letter of the 11th

October, was to correct an error in an order hastily given a month

before; when, to save time, outline instructions for this complicated

work were hurriedly sent to the manufacturer, that a commencement

might be made while the more perfect detail drawings were being

completed; the first-proposed position of the fly-wheel would prevent

the engineman from conveniently reaching the four-way cock; Trevithick

therefore suggested that the fly-wheel should be moved to the outside

of the house, and a crank placed on the end of the driving shaft

in lieu of the crank-pin in an arm of the fly-wheel. The sketch

illustrating this change makes us fully acquainted with the kind of

winding high-pressure steam-puffer engines of 8-horse power, with

open-top cylinders of 12 inches in diameter and about 3 feet 6 inch

stroke, sent to Peru in 1814. Steam, of 30 lbs. to the inch above the

pressure of the atmosphere, was admitted under the bottom of the piston

by a cock moved by an eccentric on the fly-wheel shaft; the gradual

closing of the cock reduced the supply of steam when about one-third

of the stroke had been made, wholly cutting it off some time before

its completion, making it a high-pressure steam expansive engine. The

movement of the cock then turned the steam from under the piston into

the chimney blast-pipe, and the down-stroke was performed by the weight

of the descending piston, made more than usually deep and heavy to

prevent the tendency to twist in the cylinder from the angle of the

jointed connecting rod, and also by the momentum of the fly-wheel and

its balance-weight, moving at a speed of thirty strokes a minute. Its

boiler was the Trevithick wrought-iron cylindrical, with internal tube

and fire-place, but so arranged that if necessary the fire could be

placed in brick flues under the boiler, returning through the tube.

The cylinder for the winding engine was probably fixed in the boiler,

costing, with whim-barrel and winding apparatus complete and ready for

work, 210_l._ Does the reader ask, Did so cheap an engine ever work?

Or perhaps his knowledge of engineering gives rise to the question,

How did it work? for it looks like a Newcomen of just exactly a

hundred years before, only it needs no injection water or great main

beam; and certainly it is not a Watt, for it has neither air-pump

nor condenser, nor vacuum, nor cylinder-cover, nor parallel motion,

nor any other thing like Watt invented; but it has high-pressure

steam, which he disapproved of, and it really worked thousands of

miles away, where there were no mechanics to keep it in order, and on

mountains so difficult of access, and in so light an atmosphere, that

Watt, who had the first chance of supplying steam-engines to the New

World, declared it to be impossible. The pumping engines are described

in Trevithick's note of 22nd May. They also were high-pressure

puffer-engines with open-top cylinder, 24 inches in diameter, 6-feet

stroke, with a cross-head working in guides, and side rods connecting

to the pump-rods. Two valves turned the steam on and off from under the

piston, with the ordinary gear and handles. The boiler was similar to

that for the winding engine, but larger, and had not the cylinder fixed

in it; a balance-beam regulated the movements, as it had no great main

beam, and differed from ordinary engines just as the winding engine

did. The power was 33 horses, and with an 11-inch pump barrel, 150 feet

of 11-inch pumps, a winch, and all apparatus necessary for draining the

mine, the cost was but 1400_l._

"PLOUGH INN, BLACKWALL, _December 28th, 1813_.

"MR. RASTRICK,

"Sir,--I am requested by Mr. Uville to write to you, to push the

boilers as fast as possible. A ship will sail for the South Sea

fishery in about five weeks, and will engage to take the whole of

the engines. We have not finally closed with her, because we cannot

state the exact time until we hear from you. You must not lose a

moment in sending the boiler to town. I should have gone to Cornwall

before this, but have been detained, getting a ship; and I do not like

leaving until my agreements are executed, which cannot be done until

the beginning of next week.

"I have been obliged to have all the transactions between the mines,

and the Spanish Government, and Mr. Uville, translated into English,

before the outlines of an agreement could be drawn up, which has been

a most tedious job.

"Most of the people have been out of town, and those that were not

would do no business in the Christmas, which has occasioned a loss of

near ten days.

"As soon as the agreements are executed, I will immediately send to

you money from this place. I have been kept so long here, that it will

not be worth returning to Cornwall until after Mr. Uville sails. I

shall be at Bridgenorth in about ten days, and will remain until the

work is finished. Write how the work is getting on, and what state the

winding engine is in.

"Yours, &c.,

"RD. TREVITHICK."

"DEAR SIR,

"CAMBORNE, _March 4th, 1814_.

"Your favour of the 23rd February was sent to me from Bridgenorth. I

have also received your favour of the 1st instant, and will attend to

the drawings you mention, and be prepared to meet you as early as you

please, only give me as much notice as you can.

"I hope by this time that Mr. Page has done something toward the

needful, to be at your service. I have, agreeably with your letter

this day, desired Capt. Thomas Trevarthen to hold himself in readiness

for London about the end of this month. I have not yet seen Bull. I

wish you to write me if I am to give him notice also to hold himself

in readiness for town. I fear that those two persons will not be

sufficient to conduct the work with speed, especially if Capt.

Trevarthen should be unwell; he is a good miner and pitman, and could

assist in fixing the engines. Bull can only act as an assistant to an

engineer, therefore neither of them can take the sole direction of the

work.

"There will be those four large boilers to be put together on the

spot, which neither of those persons know but little about. I think

it would take a great charge and care from your mind to have a third

person with you that could go through the whole of the undertaking,

especially as the distance from England is so great. This undertaking

of such immense magnitude and value ought not to depend solely on your

own health, as neither of the other two could get on without your

assistance in laying down and planning the outline of the whole of

the work belonging to the machinery. If any one of the parts should

be lost or broken, it would require some ability in that country to

contrive a substitute. The expense of a third able man might prevent

much loss of time and difficulty, and would not be an object in a

business of such a scale as you have commenced with.

"I recommend a third person, that you might count on a speedy and

effectual start. Even in this kingdom, where machinery is so well

understood, I have known several good undertakings fail, from not

employing at first an experienced engineer to conduct the work; which

I am doubtful would be the case at Pascoe, if you were not able to

attend yourself to the erection, and do not take a person with you for

that purpose. I beg your pardon for thus attempting to recommend to

you a third person to go out; but I think a work of this magnitude,

where expedition is important, ought not to rest on the health of one

man, especially under a changeable climate. Please to consult your

friends, and give me your opinion on it in your next.

"My health is much improved; my wife desires her best respects, and

thanks for your present. Please to write soon.

"Yours, &c.,

"RD. TREVITHICK.

"MR. UVILLE, _12, East Stien, London_."

[Rough draft.]

"MR. PAGE,

"CAMBORNE, _March 8th, 1814_.

"Sir,--Yesterday Mr. Joseph Edwards, of Truro, informed me that Teague

had given notice of trial, and that the case would come on at the

Assize on the 26th, and requested me to desire you to write to him

immediately, and give him the whole of the transaction relative to Mr.

Uville's arrest in London.

"He also wishes that some attention had been paid to the threat that

Mr. Uville received from Teague's so-called friend, so as to ascertain

whether it came direct from him, which he thought would have some

weight in court. I shall attend to give evidence at the Assize with

Mr. Edwards. I shall anxiously await a reply to my last. How does

Harvey's business get on?

"My respects to Mr. Day, and shall be very glad to find him recovering

his health as fast as I am. A crust of bread and clear air are far

preferable to luxuries enveloped in clouds of smoke and heaps of filth.

"Your obedient servant,

"RD. TREVITHICK.

"P.S.--I hear that Teague is still in London, and that his furniture

is removed to his friend's house, to save it from the hands of

surrounding evil spirits."

Trevithick showed no undue amount of discontent on discovering that

Uville had led him into pecuniary difficulties, and even his tendency

to interfere in engineering matters was not hastily resented.

In December, 1813, while in London, arranging for a vessel to convey

the engines to Lima, and also to secure written agreements with

Uville, who expected to leave England in a week or two, the going into

the documents made known many weak points, one of them being shortness

of money. The expected week or two had lengthened out to three months,

and Uville was still in London, and Capt. Thomas Trevarthen and Bull

were to be there, ready to start, about the middle of March, 1814. Four

large boilers, in pieces, were to go for the pumping engines, to be put

together in the mines; and Trevithick strongly recommended the sending

a third man, to take general charge of the practical work, which Mr.

Uville thought he himself could manage.

Page and Day were lawyers, who drew up very long documents. Money to

pay expenses was raised by the sale of shares in a company formed by

Uville without sufficient authority, and Page was to go to the mines

to look after his own and the English shareholders' interests; between

them Uville was arrested, apparently for some trifle.

[Rough draft.]

"MR. UVILLE,

"CAMBORNE, _March 15th, 1814_.

"Sir,--I shall write to him again by this post, and push him to send

down the transfer of my shares, already agreed on, for my execution,

and hope I shall be able to meet Messrs. Hazeldine and Co.'s demand

before it will be due. The young man Bull has been with me. I told

him I expected that you intended to take him with you, and Capt.

Trevarthen is making preparation for going. I am glad you intend to

take a third person with you. I have not thought or said anything to

anyone about this business. Mr. Vivian informed me that, from the

conversation he had with you on the subject, he had expected to hear

from you. I can answer for Mr. Vivian's honesty, ability, and pleasant

behaviour, and he is a person very suitable for the engagement, only

that one failing of making too free with an evening glass, which

you were not unacquainted with while in Cornwall at Dolcoath Mine. I

do not like to take an active part in this business, because if any

accident should happen to him, my sister or his family might charge me

with being accessory to his going; therefore I must beg to be exempt

from taking any part in this engagement.

"I remain, Sir, yours,

"RD. TREVITHICK."

[Rough draft.]

"MR. PAGE, "CAMBORNE, _April 9th, 1814_.

"Sir,--I have your favour of the 5th instant. I intend to be in town

on Sunday week, but this need not prevent their writing to me here;

and both you and they may still be doing your best towards disposing

of shares.

"Your obedient servant,

"RD. TREVITHICK."

[Rough draft.]

"MR. UVILLE, "CAMBORNE, _April 9th, 1814_.

"Sir,--I intend to be in London on Sunday, the 17th, and shall call

immediately on this person for money, which shall be at your service.

Wheal Alfred and Wheal Prosper agents wish you a prosperous voyage,

and success in your mines.

"I remain, Sir,

"Your obedient servant,

"RD. TREVITHICK."

Trevithick was now embarked with a crew of speculators, and in payment

for his services was made a partner, and sold a portion of his shares

to pay for the engines which Uville had ordered.

Henry Vivian, his brother-in-law, and the brother of his late partner

Andrew Vivian, wished to be the third person engaged to go with the

machinery to America. Trevithick spoke of his honesty and ability, but

declined, on account of the family relationship, to take any part in

the appointment.

The two notes on the 9th April, 1814, close the correspondence. Page

was busy selling shares to raise money, and Trevithick was to get some

money, which was to be at the service of Uville.

The delay between this period and the time of starting was mainly

caused by financial and other arrangements managed by Uville. On the

1st September, 1814, Uville, Henry Vivian, Thomas Trevarthen, and

William Bull sailed from Portsmouth for Lima in the 'Wildman,' taking

with them four pumping engines, with pump-work and rods complete; four

winding whim-engines, with all winding apparatus complete; one portable

locomotive engine on wheels, to be used for a rolling mill or other

purposes; one mill for grinding ore; and one rolling mill, probably

for the Mint at Lima. These nine steam-engines, with their apparatus

complete for work at the mines, cost 6838_l._; the grinding and rolling

mill cost 700_l._ more; but various other expenses more than doubled

the amount, which reached the large sum of over 16,000_l._

On reference to the conditions of agreement under which Uville acted,

dated 17th July, 1812, Don Pedro Abadia, Don José Arismendi, and Don

Francisco Uville, were partners engaging to drain a range of mines.

Uville was to go to London to purchase two steam-engines, and was

authorized to expend $30,000 (say 6000_l._). $2000 (say 400_l._) was to

be paid to him as the value of Trevithick's model, which he had a few

years before bought in London for 21_l._ He was to engage one or two

English workmen. No new partner was to be allowed. They also contracted

with the various workers of mines in Yauricocha, Yanacancha, Caya

Chica, Santa Rosa, and in the mining ridge of Colquijilca, for a period

of nine years, to commence within eighteen months of that time, to

sink a general pit for the drainage of those mines, and to pump out

the water by steam-engines. The payment for this drainage was to be

one-twentieth part of the ore raised by the different mines.

"An agreement made at London this 8th day of January, 1814, between

Don Francisco Uville, of Lima, in the Viceroyalty of Peru, of the one

part, and Richard Trevithick, of Camborne, in Cornwall, engineer,

of the other part. Whereas, by an agreement of partnership made and

signed at Lima, and whereas the said Francisco Uville did in pursuance

of his contract with the said miners soon after the ratification

thereof, embark for England, for the purpose of fulfilling the same on

his part, and on his arrival there in the month of April last, made

application to the said Richard Trevithick, who is an experienced

engineer and miner, and requested him to assist him in promoting

the object of his journey, which the said Richard Trevithick (being

penetrated with a high sense of its utility) agreed to do, and hath

accordingly applied himself wholly to that object, ever since the

arrival of the said Francisco Uville in England: And whereas under

the direction of the said Richard Trevithick, and by the orders of

the said Francisco Uville, various machines and engines have been

made for the purposes of the said concern, a part of which has been

already paid for by the said Francisco Uville; but several of the

bills brought by him to England not having been honoured, by reason

of the absence from England of the parties upon whom they were drawn,

the said Francisco Uville hath not at present sufficient funds to

answer the engagements he has entered into in this country, and Don

Juan ..,[**] to whom he was in that case directed by his partners to

offer shares in the said concern, and from whom he could have received

supplies, not being at this time in London, the said Francisco Uville

has agreed to admit the said Richard Trevithick to be a partner in

the concern, upon his advancing and paying a proportionable part of

the expenses necessary for carrying on the same. Now these presents

witness that in consideration of the said Richard Trevithick having

paid and agreeing by these presents to pay certain bills for machinery

ordered by the said Francisco Uville to the amount of 3000_l._

or thereabouts, the particulars of which have been ascertained

and settled by and between the said Francisco Uville and Richard

Trevithick, and also in consideration of the services which the said

Richard Trevithick hath already rendered to the said undertaking, and

of the future benefits which he is expected to perform for it, the

said Francisco Uville for himself, and on the behalf and in the name

of the said Pedro Abadia and José Arismendi (who will ratify these

presents in the capital of Lima as soon as it shall be produced to

them, to which the said Uville holds himself bound), Doth, by virtue

of the power and authority given to him by his said partners, agree to

admit the said Richard Trevithick to be a member of the said company,

and doth hereby declare him to be a member thereof and a partner

therein to the extent of 12,000 dollars, and as such, entitled to a

share and interest in all the profits and advantages of the company

in the proportion which the said sum of 12,000 dollars shall bear to

the amount of capital employed by the company in the purposes of their

establishment, which proportion will amount as nearly as can now be

ascertained to one-fifth of the capital stock embarked in the said

concern.

"FRAN. UVILLE.

"RICHARD TREVITHICK.

"_8th January, 1814._"

So Trevithick paid 3000_l._ and received nothing for his engineer's

work, to be made a partner, contrary to Uville's limit of authority, in

a speculation that proved to be not worth a farthing.

The following is a summary of the detail invoice of engines and

machinery which left London for Lima in September, 1814, in charge of

Uville, just fifteen months after his landing at Falmouth in search of

Trevithick:--

"Invoice of four steam-engines, four winding engines, one portable

rolling engine and materials for ditto, two crushing mills, four

extra-patent boilers, spare materials for engines, boring rods,

miners', blacksmiths', and carpenters' tools, &c., shipped on board

the 'Wildman,' John Leith, master, from London to Lima, by, on account

and risque of Don Francisco Uville, Don Pedro Abadia, and Don José

Arismendi, merchants at Lima. Dated 1814.

To four steam-engines of 33-horse-power each £ _s._ _d._

The nine steam-engines, including a locomotive, with its chimney,

axles, carriage-wheels, &c., a crushing mill and a rolling mill,

cost but 7560_l._ Other expenses, for freight, insurance, &c., &c.,

increased the amount to 16,152_l._

William Williams,[123] on his return from the Cerro de Pasco Mines,

states:--

[Footnote 123: Residing at Angarrack, near Hayle, 1872.]

"On the 3rd March, 1872, I saw in Yauricocha Mine two of Mr.

Trevithick's engines at work; one of them was a horizontal 12-inch

open-top cylinder pumping engine, about a 4-feet stroke; there

were two fly-wheels about 10 feet diameter and a cog-*wheel 7 feet

diameter, giving motion to two wrought-iron beams working a 10-inch

pump bucket. The other was a 12-inch cylinder winding engine with

a large fly-wheel. Three Cornish boilers, about 5 feet 6 inches

diameter, with 3 feet 9 inch tube, 30 feet long, made of 7/16ths of an

inch plates, supplied steam of 40 lbs. on the inch."
