life was enthusiastically devoted to the grand object of improving

our means of producing perfect workmanship and machinery:  to him we

are certainly indebted for the slide rest; and; consequently; to say

the least; we are indirectly so for the vast benefits which have

resulted from the introduction of so powerful an agent in perfecting

our machinery and mechanism generally。  The indefatigable care which

he took in inculcating and diffusing among his workmen; and

mechanical men generally; sound ideas of practical knowledge and

refined views of construction; have rendered and ever will continue

to render his name identified with all that is noble in the ambition

of a lover of mechanical perfection。〃



One of the first uses to which Mr。 Maudslay applied the improved

slide rest; which he perfected shortly after beginning business in

Margaret Street; Cavendish Square; was in executing the requisite

tools and machinery required by Mr。 (afterwards Sir Marc Isambard)

Brunel for manufacturing ships' blocks。  The career of Brunel was of a

more romantic character than falls to the ordinary lot of mechanical

engineers。  His father was a small farmer and postmaster; at the

village of Hacqueville; in Normandy; where Marc Isambard was born in

1769。  He was early intended for a priest; and educated accordingly。

But he was much fonder of the carpenter's shop than of the school;

and coaxing; entreaty; and punishment alike failed in making a

hopeful scholar of him。  He drew faces and plans until his father was

almost in despair。  Sent to school at Rouen; his chief pleasure was in

watching the ships along the quays; and one day his curiosity was

excited by the sight of some large iron castings just landed。  What

were they? How had they been made? Where did they come from? His

eager inquiries were soon answered。  They were parts of an engine

intended for the great Paris water…works; the engine was to pump

water by the power of steam; and the castings had been made in

England; and had just been landed from an English ship。  〃England!〃

exclaimed the boy; 〃ah! when I am a man I will go see the country

where such grand machines are made!〃 On one occasion; seeing a new

tool in a cutler's window; he coveted it so much that he pawned his

hat to possess it。  This was not the right road to the priesthood; and

his father soon saw that it was of no use urging him further:  but the

boy's instinct proved truer than the father's judgment。



It was eventually determined that he should qualify himself to enter

the royal navy; and at seventeen he was nominated to serve in a

corvette as 〃volontaire d'honneur。〃  His ship was paid off in 1792;

and he was at Paris during the trial of the King。  With the

incautiousness of youth he openly avowed his royalist opinions in the

cafe which he frequented。  On the very day that Louis was condemned

to death; Brunel had an angry altercation with some

ultra…republicans; after which he called to his dog; 〃Viens;

citoyen!〃  Scowling looks were turned upon him; and he deemed it

expedient to take the first opportunity of escaping from the house;

which he did by a back…door; and made the best of his way to

Hacqueville。  From thence he went to Rouen; and succeeded in finding a

passage on board an American ship; in which he sailed for New York;

having first pledged his affections to an English girl; Sophia

Kingdom; whom he had accidentally met at the house of Mr。 Carpentier;

the American consul at Rouen。



Arrived in America; he succeeded in finding employment as assistant

surveyor of a tract of land along the Black River; near Lake Ontario。

In the intervals of his labours he made occasional visits to New

York; and it was there that the first idea of his block…machinery

occurred to him。  He carried his idea back with him into the woods;

where it often mingled with his thoughts of Sophia Kingdom; by this

time safe in England after passing through the horrors of a French

prison。  〃My first thought of the block…machinery;〃 he once said; 〃was

at a dinner party at Major…General Hamilton's; in New York; my second

under an American tree; when; one day that I was carving letters on

its bark; the turn of one of them reminded me of it; and I thought;

'Ah! my block! so it must be。' And what do you think。  were the

letters I was cutting? Of course none other than S。  K。〃  Brunel

subsequently obtained some employment as an architect in New York;

and promulgated various plans for improving the navigation of the

principal rivers。  Among the designs of his which were carried out;

was that of the Park Theatre at New York; and a cannon foundry; in

which he introduced improvements in casting and boring big guns。  But

being badly paid for his work; and a powerful attraction drawing him

constantly towards England; he determined to take final leave of

America; which he did in 1799; and landed at Falmouth in the

following March。  There he again met Miss Kingdom; who had remained

faithful to him during his six long years of exile; and the pair were

shortly after united for life。



Brunel was a prolific inventor。  During his residence in America; he

had planned many contrivances in his mind; which he now proceeded to

work out。  The first was a duplicate writing and drawing machine;

which he patented。  The next was a machine for twisting cotton thread

and forming it into balls; but omitting to protect it by a patent; he

derived no benefit from the invention; though it shortly came into

very general use。  He then invented a machine for trimmings and

borders for muslins; lawns; and cambrics;of the nature of a sewing

machine。  His famous block…machinery formed the subject of his next

patent。



It may be explained that the making of the blocks employed in the

rigging of ships for raising and lowering the sails; masts; and

yards; was then a highly important branch of manufacture。  Some idea

may be formed of the number used in the Royal Navy alone; from the

fact that a 74…gun ship required to be provided with no fewer than

1400 blocks of various sizes。  The sheaved blocks used for the running

rigging consisted of the shell; the sheaves; which revolved within

the shell; and the pins which fastened them together。  The fabrication

of these articles; though apparently simple; was in reality attended

with much difficulty。  Every part had to be fashioned with great

accuracy and precision to ensure the easy working of the block when

put together; as any hitch in the raising or lowering of the sails

might; on certain emergencies; occasion a serious disaster。  Indeed;

it became clear that mere hand…work was not to be relied on in the

manufacture of these articles; and efforts were early made to produce

them by means of machinery of the most perfect kind that could be

devised。  In 1781; Mr。 Taylor; of Southampton; set up a large

establishment on the river Itchen for their manufacture; and on the

expiry of his contract; the Government determined to establish wo
