country are generally unfit for coking�察�and lose as much as 55 per

cent。  in the process。  But by using the hot blast�察�the coal could be

sent to the blast´furnace in its raw state�察�by which a large saving

of fuel was effected。*

 ��footnote。。。

Mr。 Mushet says�察 �The greatest produce in iron per furnace with the

Black Band and cold blast never exceeded 60 tons a´week。  The produce

per furnace now averages 90 tons a´week。  Ten tons of this I attribute

to the use of raw pit´coal�察�and the other twenty tons to the use of

hot blast。;  ��Papers on Iron and Steel�察�127。�А�The produce per furnace

is now 200 tons a´week and upwards。  The hot blast process was

afterwards applied to the making of iron with the anthracite or stone

coal of Wales�察�for which a patent was taken out by George Crane in

1836。  Before the hot blast was introduced�察�anthracite coal would not

act as fuel in the blast´furnace。  When put in�察�it merely had the

effect of putting the fire out。  With the aid of the hot blast��

however�察�it now proves to be a most valuable fuel in smelting。

Even coals of an inferior quality were by its means made available

for the manufacture of iron。  But one of the peculiar qualities of the

Black Band ironstone is that in many cases it contains sufficient

coaly matter for purposes of calcination�察�without any admixture of

coal whatever。  Before its discovery�察�all the iron manufactured in

Scotland was made from clay´band�察�but the use of the latter has in a

great measure been discontinued wherever a sufficient supply of Black

Band can be obtained。  And it is found to exist very extensively in

most of the midland Scotch counties��the coal and iron measures

stretching in a broad belt from the Firth of Forth to the Irish

Channel at the Firth of Clyde。  At the time when the hot blast was

invented�察�the fortunes of many of the older works were at a low ebb��

and several of them had been discontinued�察�but they were speedily

brought to life again wherever Black Band could be found。  In 1829��

the year after Neilson's patent was taken out�察�the total make of

Scotland was 29��000 tons。  As fresh discoveries of the mineral were

made�察�in Ayrshire and Lanarkshire�察�new works were erected�察�until�察�in

1845�察�we find the production of Scotch pig´iron had increased to

475��000 tons。  It has since increased to upwards of a million of tons��

nineteen´twentieths of which are made from Black Band ironstone。*

 ��footnote。。。

It is stated in the North British Review for Nov。 1845�察�that ;As in

Scotland every furnacewith the exception of one at Carronnow uses

the hot blast the saving on our present produce of 400��000 tons of

pig´iron is 2��000��000 tons of coals�察�200��000 tons of limestone�察�and

#650��000 sterling per annum。;  But as the Scotch produce is now above

a million tons of pig´iron a year�察�the above figures will have to be

multiplied by 2 1/2 to give the present annual savings。

 。。。��



Employment has thus been given to vast numbers of our industrial

population�察�and the wealth and resources of the Scotch iron districts

have been increased to an extraordinary extent。  During the last year

there were 125 furnaces in blast throughout Scotland�察�each employing

about 400 men in making an average of 200 tons a week�察�and the money

distributed amongst the workmen may readily be computed from the fact

that�察�under the most favourable circumstances�察�the cost of making

iron in wages alone amounts to 36s。 a´ton。*

An immense additional value was given to all land in which the Black

Band was found。  Mr。 Mushet mentions that in 1839 the proprietor of

the Airdrie estate derived a royalty of 16��500L。 from the mineral��

which had not before its discovery yielded him one farthing。  At the

same time�察�many fortunes have been made by pushing and energetic men

who have of late years entered upon this new branch of industry。

Amongst these may be mentioned the Bairds of Gartsherrie�察�who vie

with the Guests and Crawshays of South Wales�察�and have advanced

themselves in the course of a very few years from the station of

small farmers to that of great capitalists owning estates in many

counties�察�holding the highest character commercial men�察�and ranking

among the largest employers of labour in the kingdom。

MECHANICAL INVENTIONS AND INVENTORS。

Tools have played a highly important part in the history of

civilization。  Without tools and the ability to use them�察�man were

indeed but a ;poor�察�bare�察�forked animal�察�worse clothed than the

birds�察�worse housed than the beaver�察�worse fed than the jackal。  ;Weak

in himself�察─�says Carlyle�察 �and of small stature�察�he stands on a

basis�察�at most for the flattest´soled�察�of some half square foot��

insecurely enough�察�has to straddle out his legs�察�Jest the very wind

supplant him。  Feeblest of bipeds�  �Three quintals are a crushing load

for him�察�the steer of the meadow tosses him aloft like a waste rag。

Nevertheless he can use tools�察�can devise tools�此 �with these the

granite mountain melts into light dust before him�察�he kneads glowing

iron as if it were soft paste�察�seas are his smooth highway�察�winds and

fire his unvarying steeds。  Nowhere do you find him without tools�此 �

without tools he is nothing�察�with tools he is all。;  His very first

contrivances to support life were tools of the simplest and rudest

construction�察�and his latest achievements in the substitution of

machinery for the relief of the human hand and intellect are founded

on the use of tools of a still higher order。  Hence it is not without

good reason that man has by some philosophers been defined as A

TOOL´MAKING ANIMAL。



Tools�察�like everything else�察�had small beginnings。  With the primitive

stone´hammer and chisel very little could be done。  The felling of a

tree would occupy a workman a month�察�unless helped by the destructive

action of fire。  Dwellings could not be built�察�the soil could not be

tilled�察�clothes could not be fashioned and made�察�and the hewing out

of a boat was so tedious a process that the wood must have been far

gone in decay before it could be launched。  It was a great step in

advance to discover the art of working in metals�察�more especially in

steel�察�one of the few metals capable of taking a sharp edge and

keeping it。  From the date of this discovery�察�working in wood and

stone would be found comparatively easy�察�and the results must

speedily have been felt not only in the improvement of man's daily

food�察�but in his domestic and social condition。  Clothing could then

be made�察�the primitive forest could be cleared and tillage carried

on�察�abundant fuel could be obtained�察�dwellings erected�察�ships built��

temples reared�察�every improvement in tools marking a new step in the

development of the human intellect�察�and a further stage in the

progress of human civilization。



The earliest tools were of the simplest possible character��

consisting principally of modifications of the wedge�察�such as the

knife�察�the shears ��formed of two knives working on a joint���察�the

chisel�察�and the axe。  These�察�with the primitive hammer�察�formed the

principal stock´in´trade of the early mechanics�察�who were

handicraftsmen in the literal sense of the word。  But the work which

the early craftsmen in wood�察�stone�察�brass�察�and iron�察�contrived to

execute�察�sufficed to show how much expertness in the handling of

tools will serve to compensate for their mechanical imperfections。

Workmen then sought rather to aid muscular strength than to supersede

it�察�and mainly to facilitate the efforts of manual skill。  Another

tool became added to those mentioned above�察�which proved an

additional source of power to the workman。  We mean the Saw�察�which was

considered of so much importance that its inventor was honoured with

a place among the gods in the mythology of the Greeks。  This invention

is said to have been suggested by the arrangement of the teeth in the

jaw of a serpent�察�used by Talus the nephew of Daedalus in dividing a

piece of wood。  From the representations of ancient tools found in the

paintings at Herculaneum it appears that the frame´saw used by the

ancients very nearly resembled that still in use�察�and we are informed

that the tools employed in the carpenters' shops at Nazareth at this

day are in most respects the same as those represented in the buried

Roman city。  Another very ancient tool referred to in the Bible and in

Homer was the File�察�which was used to sharpen weapons and implements。

Thus the Hebrews ;had a file for the mattocks�察�and for the coulters��

and for the forks�察�and for the axes�察�and to sharpen the goads。;*

 ��footnote。。。

 。。。��

When to these we add the adze�察�plane´irons�察�the anger�察�and the

chisel�察�we sum up the tools principally relied on by the early

mechanics for working in wood and iron。



Such continued to be the chief tools in use down almost to our own

day。  The smith was at first the principal tool´maker�察�but special

branches of trade were gradually established�察�devoted to tool´making。

So long�察�however�察�as the workman relied mainly on his dexterity of

hand�察�the amount of production was comparatively limited�察�for the

number of skilled workmen was but small。  The articles turned out by

them�察�being the product of tedious manual labour�察�were too dear to

come into common use�察�and were made almost exclusively for the richer

classes of the community。  It was not until machinery had been

invented and become generally adopted that many of the ordinary

articles of necessity and of comfort were produced in sufficient

abundance and at such prices as enabled them to enter into the

consumption of the great body of the people。



But every improver of tools had a long and difficult battle to fight��

for any improvement in their effective power was sure to touch the

interests of some established craft。  Especially was this the case

with machines�察�which are but tools of a more complete though

complicated kind than those above described。



Take�察�for instance�察�the case of the Saw。  The tedious drudgery of

dividing timber by the old fashioned hand´saw is well known。  To avoid

it�察�some ingenious person suggested that a number of saws should be

fixed to a frame in a mill�察�so contrived as to work with a

reciprocating
