during the experiments。



I completed the prescribed drawings and specifications; and sent

them; together with the model; to Somerset House。  Some 280

schemes of lifeboats were submitted for competition; but mine was

not successful。  I suspect that the extreme novelty of the

arrangement deterred the adjudicators from awarding in its

favour。  Indeed; the scheme was so unprecedented; and so entirely

out of the ordinary course of things; that there was no special

mention made of it in the report afterwards published; and even

the description there given was incorrect。  The prize was awarded

to Mr。 James Beeching; of Great Yarmouth; whose plans were

afterwards generally adopted by the Lifeboat Society。  I have

preserved my model just as it was; and some of its features have

since been introduced with advantage into shipbuilding。'1'



The firm of Robert Stephenson and Co。 having contracted to build

for the Government three large iron caissons for the Keyham

Docks; and as these were very similar in construction to that of

an ordinary iron ship; draughtsmen conversant with that class of

work were specially engaged to superintend it。  The manager;

knowing my fondness for ships; placed me as his assistant at this

new work。  After I had mastered it; I endeavoured to introduce

improvements; having observed certain defects in laying down the

linesI mean by the use of graduated curves cut out of thin

wood。  In lieu of this method; I contrived thin tapered laths of

lancewood; and weights of a particular form; with steel claws and

knife edges attached; so as to hold the lath tightly down to the

paper; yet capable of being readily adjusted; so as to produce

any form of curve; along which the pen could freely and

continuously travel。  This method proved very efficient; and it

has since come into general use。



The Messrs。 Stephenson were then also making marine engines; as

well as large condensing pumping engines; and a large tubular

bridge to be erected over the river Don。  The splendid high…level

bridge over the Tyne; of which Robert Stephenson was the

engineer; was also in course of construction。  With the

opportunity of seeing these great works in progress; and of

visiting; during my holidays and long evenings; most of the

manufactories and mines in the neighbourhood of Newcastle; I

could not fail to pick up considerable knowledge; and an

acquaintance with a vast variety of trades。  There were about

thirty other pupils in the works at the same time with myself;

some were there either through favour or idle fancy; but

comparatively few gave their full attention to the work; and I

have since heard nothing of them。  Indeed; unless a young fellow

takes a real interest in his work; and has a genuine love for it;

the greatest advantages will prove of no avail whatever。



It was a good plan adopted at the works; to require the pupils to

keep the same hours as the rest of the men; and; though they paid

a premium on entering; to give them the same rate of wages as the

rest of the lads。  Mr。 William Hutchinson; a contemporary of

George Stephenson; was the managing partner。  He was a person of

great experience; and had the most thorough knowledge of men and

materials; knowing well how to handle both to the best advantage。



His son…in…law; Mr。 William Weallans; was the head draughtsman;

and very proficient; not only in quickness but in accuracy and

finish。  I found it of great advantage to have the benefit of the

example and the training of these very clever men。



My five years apprenticeship was completed in May 1851; on my

twentieth birthday。  Having had but very little 〃black time;〃 as

it was called; beyond the half…yearly holiday for visiting my

friends; and having only 〃slept in〃 twice during the five years;

I was at once entered on the books as a journeyman; on the 〃big〃

wage of twenty shillings a week。  Orders were; however; at that

time very difficult to be had。



Railway trucks; and even navvies' barrows; were contracted for in

order to keep the men employed。  It was better not to discharge

them; and to find something for them to do。  At the same time it

was not very encouraging for me; under such circumstances; to

remain with the firm。  I therefore soon arranged to leave; and

first of all I went to see London。  It was the Great Exhibition

year of 1851。  I need scarcely say what a rich feast I found

there; and how thoroughly I enjoyed it all。  I spent about two

months in inspecting the works of art and mechanics in the

Exhibition; to my own great advantage。  I then returned home;

and; after remaining in Scarborough for a short time; I proceeded

to Glasgow with a letter of introduction to Messrs。 J。 and G。

Thomson; marine engine builders; who started me on the same wages

which I had received at Stephenson's; namely twenty shillings a

week。



I found the banks of the Clyde splendid ground for gaining

further mechanical knowledge。  There were the ship and engine

works on both sides of the river; down to Govan; and below there;

at Renfrew; Dumbarton; Port Glasgow; and Greenockno end of

magnificent yardsso that I had plenty of occupation for my

leisure time on Saturday afternoons。  The works of Messrs。 Robert

Napier and Sons were then at the top of the tree。  The largest

Cunard steamers were built and engined there。  Tod and Macgregor

were the foremost in screw steamshipsthose for the Peninsular

and Oriental Company being splendid models of symmetry and works

of art。  Some of the fine wooden paddle…steamers built in Bristol

for the Royal Mail Company were sent round to the Clyde for their

machinery。  I contrived to board all these ships from time to

time; so as to become well acquainted with their respective

merits and peculiarities。



As an illustration of how contrivances; excellent in principle;

but defective in construction; may be discarded; but again taken

up under more favourable circumstances; I may mention that I saw

a Hall's patent surface…condensor thrown to one side from one of

these steamers; the principal difficulty being in keeping it

tight。  And yet; in the course of a very few years; by the

simplest possible contrivanceinserting an indiarubber ring

round each end of the tube (Spencer's patent)surface

condensation in marine engines came into vogue; and there is

probably no ocean…going steamer afloat without it; furnished with

every variety of suitable packings。



After some time; the Messrs。 Thomson determined to build their

own vessels; and an experienced naval draughtsman was engaged; to

whom I was 〃told off〃 whenever he needed assistance。  In the

course of time; more and more of the ship work came in my way。 

Indeed; I seemed to obtain the preference。  Fortunately for us

both; my superior obtained an appointment of a similar kind on

the Tyne; at superior pay; and I was promoted to his place。  The

Thomsons had now a very fine shipbuilding…yard; in full working

order; with sever
