WOOLWICH a.r.s.eNAL.

Since early days, Woolwich has been an important centre for warships and war-material. Here ships were built and launched when England first began to have a navy of specially constructed men-of-war, for Henry VIII. established the Woolwich dockyard, and also appointed Commissioners of the navy, and formed the Navy Office. Some of the earliest three-deckers, or, as we may almost call them, five-deckers, were built at this dockyard; and of these the most famous was the _Great Harry_, so named after the king, which was launched here in 1514. For the period, the ship was a large one, being of a thousand tons burden; though we should not think much of her size now, when we have ironclads of over eleven thousand tons. There are models of her in the Greenwich Naval Museum, which is not far from Woolwich; and a curious lofty wooden castle she is, rising far up above the water-line, and offering a fair target, if the cannon of those days had any accuracy.

[Ill.u.s.tration: The _Great Harry_.]

On June 3, 1559, Queen Elizabeth came down to Woolwich to witness the launch of a large ship called after her name. In 1637 a ship half as large again as the _Great Harry_ was launched at Woolwich. She was the marvel of her days, and though named the _Royal Sovereign_, was more often called the _Golden Devil_, from the amount of mischief she wrought in the Dutch fleet. Her guns were probably of small size; but she carried enough of them on her three flush-decks, her forecastle, her half-deck, her quarter-deck, and in her round-house; for in her lower tier were sixty ports; in the middle, thirty; in the third, twenty-six; in her forecastle were twelve; in her half-deck were fourteen. She was decorated in the emblematical style of the time with gilding and carvings; and these designs were the work of one Thomas Haywood, an actor, who has left us an account of the ship which he adorned, in a quarto volume published the same year in which she was launched. We can imagine what she looked like, with her lofty forecastle and p.o.o.p, the latter provided with five lanterns, one of which, we are told, was large enough to contain ten persons.

Old Samuel Pepys gives us many references to Woolwich in his famous _Diary_. He paid frequent visits to the dockyard on his duties as Secretary to the Admiralty, and seems to have looked after his business well. For instance, on June 3, 1662, he writes: 'Povy and Sir W. Batten and I by water to Woolwich; and there saw an experiment made of Sir R.

Ford's Holland yarn, about which we have lately had so much stir; and I have much concerned myself for our rope-maker, Mr Hughes, who represented it so bad; and we found it to be very bad, and broke sooner than, upon a fair trial, five threads of that against four of Riga yarn; and also that some of it had old stuff that had been tarred, covered over with new hemp, which is such a cheat as hath not been heard of.'

The next month he is looking after the hemp again, and writes: 'To Woolwich to the rope-yard, and there looked over several sorts of hemp, and did fall upon my great survey of seeing the working and experiments of the strength and charge in the dressing of every sort; and I do think have brought it to so great a certainty, as I have done the king some service in it, and do purpose to get it ready against the Duke's coming to town to present to him.' He adds pathetically: 'I see it is impossible for the king to have things done as cheap as other men.'

Of as early date probably as the dockyard, was the 'Warren,' the name by which the a.r.s.enal was formerly called. This establishment seems to have begun as a cannon-foundry, and such, indeed, it chiefly continues to be.

Moreover, in other days when the dockyard flourished, stores of ships'

cannon were kept here, ready to be placed on ships as soon as commissioned. But now that the dockyard is a thing of the past, and now that the large building-slips, workshops, and ropewalk are empty, the cannon at the a.r.s.enal are chiefly those for the royal artillery and for forts. The dockyard has been closed since 1869; its broad roads are deserted, its workshops are silent, and its large sheds are only used for stores; but the a.r.s.enal has increased in magnitude; and the 'Warren,' in which, before the establishment of the Plumstead magazines, powder was proved ('before the princ.i.p.al engineers and officers of the Board of Ordnance, to which many of the n.o.bility and gentry were often invited, and afterwards sumptuously entertained by them'), has now become an enormous establishment, covering acres of ground, and containing workshops provided with the most complicated machinery, and foundries of enormous size. It is round this a.r.s.enal that we propose to take the reader.

Having gained admittance, the visitor is put in charge of a guide. The tapping of the great furnace is a remarkable sight. A stream of molten steel runs into a huge tank which can contain four or five tons of metal, and this tank is dragged off by some score of men to fill the various moulds. It is remarkable, also, to see a huge steam-hammer of some forty tons' force welding a ma.s.s of metal at white-heat.

The a.r.s.enal is divided into four departments--the Laboratory, the Gun Factory, the Gun-carriage Department, and the Stores; and of these four divisions, the first two contain the chief things not to be found in very many other places.

The Gun-carriage Department has workshops both for metal and wood work, and each branch contains many subdivisions. There is nothing, however, in this department which is peculiar to the a.r.s.enal, with the exception, of course, of the special articles which are manufactured; that is to say, forging, steam-carpentering, wheel-making, and so on, are carried out as they would be executed elsewhere. The guides always make a point of showing the wheel-shoeing pit, as it is called, in which the tyre is put on a gun-wheel. The machinery in this department is very complete, especially in the carpenters' shops, where the lathes which work automatically, and turn wheel-spokes and such things according to a given pattern, and the steam-saws for cutting dovetails for sides of boxes, and other machinery, are all constructed on highly ingenious principles. With regard to the articles constructed, the trail of a gun may be followed in all stages of its construction until it appears complete with its wheels, and ready for the gun to be placed on it.

Here, too, may be seen the ingenious Moncrieff gun-carriage, by which the gun is only raised above a fortification at the moment when it is fired, the 'sighting' being done from below by an arrangement of mirrors.

The Stores, again, are remarkable only for the quant.i.ty of material stowed away ready for use. For instance, there are ten thousand complete sets of harness for guns and baggage wagons always kept in stock. But when the visitor has just walked once through these storehouses, he will probably have seen all that he cares to see there.

It is, however, when we come to the Gun Factory that the special interest of the a.r.s.enal begins. Imagine a huge ma.s.s of steel welded--for casting would not give sufficient strength--into the form of the trunk of a large fir-tree, and you have the first stage of a gun's existence.

This solid ma.s.s is to form the tube of a cannon, and the solid core has to be removed by ingenious and powerful machinery. It takes a week or two to bore the interior of some of the larger guns. Some of the machines are constructed to bore a hole which is continually enlarged by successive tools; while others actually cut out a round solid ma.s.s from the interior. The tube has also to be subjected to the process of being turned both within and without, and it is then fit for the next process, which is that of cutting the grooves within it which give the required spin to the projectile, commonly called rifling. This is a delicate and intricate process, for the utility of the gun of course depends largely on the accuracy with which the grooves are made. The actual cutting is performed by a machine which travels up the tube at the required spiral; but as the work proceeds, the man in charge carefully examines the grooves along their whole length with the aid of a candle fixed at the end of a long rod which he pushes up the tube.

But when the tube has been bored, turned, and rifled, the gun is by no means finished. The tube by itself would be far too delicate for the large charges of powder employed; and, consequently, it has to be fitted at the breech end with two or three outer cases or jackets, the outside one of which bears the trunnions on which the gun rests. At last the gun is completed; and the next thing is to subject it to a severe test by firing from it a charge of powder proportioned to its size. For this purpose, it has to be taken to Plumstead Marshes, a portion of which forms the testing-ground and powder-magazines connected with the a.r.s.enal. Lines of railway run down to the marshes, and the gun is mounted on a truck and dragged off by a locomotive to the place appointed for its trial. It may be mentioned that lines of railway run in all directions through the a.r.s.enal, one of narrow gauge being introduced into most of the workshops, so that the visitor has to keep a lookout lest a tiny locomotive with a train of what may almost be called toy trucks should bear down upon him as he is walking along.--But to return to the gun. When it has been finally tested, cleaned, polished, and stamped, it is coated with a particular varnish, and is fit for service.

The next most interesting place to the Gun Factory is the Laboratory, where sh.e.l.ls and bullets are manufactured. Sh.e.l.ls are cast rough, and then finished off in a lathe. A band of copper now usually takes the place of the copper studs which were formerly inserted to enable the sh.e.l.l to fit into the rifled grooves. This band is expanded by the force of the explosion when the gun is fired, and fills up the grooves, so as to give the necessary spin to the sh.e.l.ls. Sh.e.l.ls are charged with their interior bullets at the Laboratory; but the powder is added down at the marshes. A sh.e.l.l when completed has become a very expensive article, especially if it is a large one. Some of those projectiles are so heavy that the guns from which they have to be fired are provided with small cranes for lifting them up to the breech. The sh.e.l.ls are, like the guns, beautifully finished off and varnished, and then sent off to the stores.

Perhaps the most interesting place in the Laboratory department is the Pattern Room, which is a sort of museum where shot and sh.e.l.ls of all sorts are to be seen, from the old-fashioned chain-shot, made of round b.a.l.l.s fastened together, to the most perfect specimens of modern sh.e.l.ls.

Here, also, are to be seen those strange weapons of modern warfare called torpedoes, amongst them the famous 'fish torpedo,' which with its complicated mechanism may be almost described as an under-water ship. It is so constructed that it finds its way unseen and unheard, with its terrible charge of dynamite, to the side of a hostile vessel.

THE ENFIELD SMALL-ARMS FACTORY.

It is at Enfield, on the river Lea, some twelve miles down the Great Eastern Railway, that small-arms are manufactured, almost entirely, as required by our army.

Enfield Factory has not, like Woolwich a.r.s.enal, an ancient history of its own. In the days of Henry VIII. and of Elizabeth, of the Duke of York and his faithful secretary, Samuel Pepys, Woolwich was famous for the production both of ships and of guns; but the small-arms factory on the borders of Ess.e.x dates only from the early part of this century. Its site seems to have been chosen regardless of any peculiar advantages for manufacturing purposes. It is simply a collection of workshops built in the flat meadows through which run the various branches, natural and artificial, of the lazy Lea; and the nearest town, about a mile and a half distant, is quiet and remote little Waltham, chiefly known for its Abbey Church, the burial-place of King Harold, which rises in its midst.

The situation of the Enfield Factory is, however, advantageous in this way: the ca.n.a.ls form a safe means of water transit for the gunpowder which is manufactured in the adjacent mills at Waltham, and which is required at Enfield for use in the proving of the barrels of firearms; while the far-stretching marshes provide an apparently interminable range for carrying out the necessary experiments and trials with regard to the accuracy of the weapons manufactured.

Where one of the ca.n.a.ls has been conducted into a square-shaped basin, the older and princ.i.p.al buildings of the manufactory have been located.

They form a quadrangle of some extent; and here, too, are situated the offices and the quarters of the executive staff, which is composed partly of civilians and partly of military officers. Behind these, on the east side of the enclosure, and on the banks of one of the ca.n.a.ls, are rows of workmen's cottages. Near the entrance gates are situated schools for the workmen's children; and at the other end of this street, as we may call it, is a church, which is served by the clergy of the parish of Enfield. On the west side extend north and south the flat meadows or marshes which form so convenient a spot for the testing and proving of the rifles.

All sorts of personal weapons required for the arming of a soldier in the English army are made here, not only firearms, such as rifles and revolvers, but lances, swords, and bayonets, the last having now become a sort of short sword. There is also one cla.s.s of weapons which occupies a sort of intermediate position between those carried by the soldier himself and those drawn by horses--that of machine guns, as they are called, which, though not carried by men on their shoulders or in their hands, are drawn about by them on small carriages. These machine guns are cla.s.sed with personal arms, because they are usually employed in connection with infantry; and also because--which is a far more important reason--the ammunition required for them is similar to that used in rifles. In fact, they are in principle only a collection of infantry rifles fastened together, or, as we shall see, a single rifle barrel with machinery attached which enables it to discharge with great rapidity.

There is one more general principle which we shall do well to bear in mind before we enter the factory. It is this, that of course the manufacture of small-arms is in as much a condition of uncertainty as that of larger warlike weapons in these days. What we see now may become obsolete in a very short time, and we shall be shown specimens of firearms which formed the universal weapons of the British army only a very few years ago, but are now as much out of date for practical purposes as cross-bows. Remembering this, let us go first when we enter to one of the offices, where we shall see arranged in a rack against the wall, amongst others, specimens of the old Enfield muzzle-loader, of the same weapon converted into a breech-loader, of the Martini-Henry rifle, and of the latest pattern of all, the magazine rifle. While, stored away in some out-of-the-way corner, it is just possible we might come across a specimen of the old smooth-bore or 'Brown Bess,' which formed the weapon of certain English linesmen so late as the beginning of the Crimean War.

The Enfield workshops are of course in appearance much like other workshops. There are the same processes of forging and casting, and the same machinery for hammering and turning and boring and drilling which we see elsewhere.

A rifle, as every one knows, consists of three portions--the wooden stock, the barrel, and the lock. The stock is usually made of walnut wood, and is manufactured in what we should perhaps describe as a carpenter's shop. Formerly, the stock of a rifle was formed out of one long piece of timber; but now the complicated machinery of the breech and lock cannot be contained in a hollow in the wood, as was formerly the case, but has to be enclosed in a steel case, to which the wooden b.u.t.t and barrel support are screwed. To the rifles of the newest pattern there hangs, just below the lock, the magazine, in which are carried five or, in some cases, ten cartridges, which spring up into place in turn, ready to be discharged. In short, the rifle has become, as regards its rapidity of action, something similar to a revolver pistol. We shall find that a lock has in its manufacture to pa.s.s through an almost infinite number of processes, each part having to be forged or beaten out till the whole can be fitted together.

Let us pa.s.s on to the barrel-making shop. Rifle barrels are made from a solid round bar of steel, which is at first considerably shorter and stouter than the finished barrel will be. This steel bar is heated red-hot, and is pa.s.sed between several pairs of rollers, which convert it outwardly into the required form. It has, however, afterwards to be bored and then rifled--that is, furnished with the spiral grooves within, which gives the bullet the necessary spin. Of course the barrel is by far the most important portion of a firearm, and the barrels of rifles are, at Enfield, tested and proved in the most ingenious and searching manner. The first proof takes place after the barrel has been bored, but before it is rifled. The barrels are loaded with cartridges of considerably greater weight both in powder and bullet than those which will be used in them when they are ready for service, and are enclosed in a sort of strong box which has one side open. They are then discharged through the open side into a heap of sand, and examined; but it is a rare event to find a barrel that has not been able to bear this test. The second proof, which takes place after the rifling, is of a similar character.

But these proofs are only to test the strength of a barrel; the test of its accuracy is a much more delicate operation. Of course the machinery by which it is bored and rifled works with the most admirable precision; but yet it is necessary to put this machine-work to trial. There are, amongst others, two highly ingenious methods for doing this. In the one case it is placed on a stand which is so constructed that on it the barrel can be made to revolve rapidly. The barrel is pointed towards a window, and in front of it is a fixed sight. The workman looks through it while it is revolving; and if the sight remains steady to his eye, that is a proof that the barrel may be said to be straight. But there is yet another method. The mechanism of this testing apparatus is rather difficult to describe, but is something of this fashion. The barrel is made to revolve as before; but this time there is inserted in it a spindle, on which is fixed a short arm with a point which touches very lightly the interior of the barrel. If there is any inequality, or if the barrel is not perfectly straight, this short arm is of course shaken, and when this is the case, the motion is further communicated to a long arm at the end of which is an indicator, which is looked at by the workman through a magnifying gla.s.s.

[Ill.u.s.tration: Gatling Gun on Field Carriage.]

Barrel, stock, and lock being at last completed and tested, the rifle is put together; but even then it is subjected to one more trial. This is carried out on the proof-ground in the marshes, and takes the form of an actual discharge of the weapon at a target. The rifle is screwed to a fixed and firm support, and then a certain number of rounds are fired at ranges of five hundred and one thousand yards respectively. In this test the hitting of the centre of the target, or 'bull's-eye,' is not the end in view, as it is in ordinary target practice. That sort of shooting depends of course on the steadiness with which the marksman holds the rifle. In this case, however, the fixed _rest_ may be directed on any portion of the target, and the _grip_ will always be the same. The only object of the test is to see whether the rifle throws the bullet at each round on or near the same spot. A marker at the b.u.t.t examines the position of each shot, and the smaller the s.p.a.ce on which they strike, the better the weapon.

We have not yet spoken of the machine guns. These weapons are, as part of the regular equipment of armies, quite modern, though the idea of binding together a quant.i.ty of barrels and then discharging them at once, or with great rapidity one after another, is not altogether novel.

Sometimes, instead of a number of barrels, one only is required, and the cartridges are discharged from short barrels or chambers which are brought in turn into position with the longer one. This is the ordinary revolver system; but modern machine guns are a great improvement on this method, and entirely dispense with the necessity of loading separate chambers. Machine guns have succeeded one another with extraordinary rapidity, and a gun seems only to be adopted in order to be superseded.

Thus we have had during the last few years a series of these weapons bearing the names of Gatling, Gardner, Nordenfelt, and Maxim, described on a later page.

[Ill.u.s.tration: Nordenfelt-Palmcrantz Gun mounted on Ship's Bulwark.]

As we walk about the factory we see, besides the workmen, here and there groups of men in military uniform. These are armourer sergeants, who attend cla.s.ses at which they are taught the mysterious mechanism of the breech-loaders and machine guns. In former days, Tommy Atkins could be instructed how to keep his weapon in order, lock and all; but now its complications are beyond the power of his understanding or of his fingers, perhaps of both, and he has to hand over his rifle to a more skilled superior when it is out of order. Truly, military matters, from the movement of the vast army corps of the present day down to the mechanism of the soldier's weapons, have become a highly technical matter.

LORD ARMSTRONG AND THE ELSWICK WORKS.

Sir W. G. Armstrong, the chairman and founder of this great firm of warship builders and makers of big guns at Elswick, Newcastle-on-Tyne, is the son of a c.u.mberland yeoman, and born at Newcastle in 1810. He early showed a turn for mechanical contrivances, and delicate youth as he was, when confined to the house he was quite happy making toys of old spinning-wheels and such-like things. He would also spend hours in a joiner's shop, copying the joiner's work, and making miniature engines.

He had ample opportunity in his father's house of making himself acquainted with chemistry, electricity, and mechanics. In spite of his turn for mechanics, he was articled to a solicitor, who, at the finish of his apprenticeship, made him his partner. In his leisure hours he conducted his experiments. Fishing was also a favourite pastime with him, and in 1836, while rambling through Dent Dale, he saw a stream descending from a great height and driving only one single mill. This led him to think that there might be a more economical use of this water hydraulically, with the result that he produced a hydraulic engine, which was followed by the invention of a hydraulic crane for raising weights at harbours and in warehouses. It was soon adopted at the Albert Dock, Liverpool, and elsewhere.

[Ill.u.s.tration: LORD ARMSTRONG.]

Next he invented an apparatus for extracting electricity from steam, afterwards introduced into the Polytechnic Inst.i.tution, London. Napoleon III. heard of this famous machine, and sent experts to examine it.

Armstrong began to receive recognition; he was elected a member of the Royal Society in 1846, and a year later, aided by some friends, he began on a small scale the Elswick Engine-works in the suburbs of Newcastle, which have grown to be the largest concern of the kind in the country.

At first the enterprise chiefly consisted in the manufacture of hydraulic cranes, engines, acc.u.mulators, and bridges.

The addition of ordnance and shipping, for which Armstrong became chiefly known, came later. Previous to the year 1853, the weapon used by the infantry portion of the British army was a clumsy smooth-bore musket, which was only effective up to three hundred yards at the farthest; the usual distance at which practice was made by the soldier seldom exceeding one hundred yards. In the above-named year, an arm was brought into use, termed, from the locality of its manufacture, the Enfield rifle. This weapon being lighter, and possessing a much greater range than the old small-arm, Brown Bess, as it was called, threatened very seriously to diminish the effect of field-artillery, if not to abolish that arm entirely, as, indeed, many infantry officers were sanguine enough to predict. Nor were they without good reason for their boasting, the only field-artillery consisting of 6-pounder bra.s.s guns for horse-artillery, 9-pounder guns for field-batteries, and sometimes 12-pounder and 18-pounder guns as batteries of position--that is to say, batteries used when the general of a force meant to make any stand in a suitable position; on these occasions, the guns were taken to the requisite places, and there left. Now, all these guns were smooth-bored; and as the range of the 6 and 9 pounders was limited in practice to about one thousand yards, it was a fair enough supposition that a company of concealed riflemen with their Enfield rifles could pick off the gunners and remain themselves comparatively secure, especially as their muskets being sighted up to, and effective at, eleven hundred yards, the guns also would be a good mark to aim at, and the riflemen hard to see, even if exposed.

Such was the state of affairs when Armstrong stepped in to the rescue of the artillery, and provided the British government with the rifled cannon now in use, and about which so much has been written.

Armstrong, during the Crimean War, made an explosive apparatus for blowing up ships sunk at Sebastopol. This led him to turn his attention to improvements in ordnance. He invented a kind of breech-loading cannon, and soon had an order for several field-pieces after the same pattern. He began with guns throwing 6 lb. and 18 lb. shot and sh.e.l.ls, and afterwards 32 lb. sh.e.l.ls; and the results at the time were deemed almost incredible. He had both reduced the weight of the gun by one-half, reduced the charge of powder, and his gun sent the sh.e.l.l about three times farther. His success led to his offering to government all his past inventions, and any that he might in the future discover. A post was created for him, that of Chief Engineer of Rifled Ordnance for seven years provisionally.

The founder of this great firm was knighted by the Queen in 1858, and made C.B. In 1887 he was raised to the peerage as Baron Armstrong of Cragside. His mansion and estate of Cragside is at Rothbury, and it is fitted up with the electric light and every convenience of wealth and taste. Armstrong's peculiar partnership between government and the Elswick Works was brought to a close in 1863, since which time the progress of the firm has been continuous. In 1882 an amalgamation took place between the Elswick Works and the firm of Charles Mitch.e.l.l & Co., shipbuilders at Low Walker. Dr Mitch.e.l.l, who was a native of Aberdeen, and a munificent donor to Newcastle and Aberdeen, was one of the directors of Armstrong, Mitch.e.l.l, & Co. till his death in 1895.
