Let us examine into the history and the course of the Wall of London, if only for the very remarkable facts that the boundary of the City was determined for fifteen hundred years by the erection of this Wall; that for some purposes the course of the Wall still affects the government of London; and that it was only pulled down bit by bit in the course of the last century. You will see by reference to the map what was the course of the Wall. It began, starting from the east where the White Tower now stands. Part of the foundation of the Tower consists of a bastion of the Roman wall. It followed a line nearly north as far as Aldgate. Then it turned in a N.W. direction just north of Camomile Street and Bevis Marks to Bishopsgate. Thence it ran nearly due W., north of the street called London Wall, turning S. at Monkwell Street. At Aldersgate it turned W. until it reached Newgate, where it turned nearly S. again and so to the river, a little east of the present Blackfriars Bridge. It ran, lastly, along the river bank to join its eastern extremity. The river wall had openings or gates at Dowgate and Bishopsgate,{39} and probably at Queen Hithe. The length of the Wall, without counting the river side, was 2 miles and 608 feet. This formidable Wall was originally about 12 feet thick made of rubble and mortar, the latter very hard, and faced with stone. You may know Roman work by the courses of tiles or bricks. They are arranged in double layers about 2 feet apart. The so-called bricks are not in the least like our bricks, being 6 inches long, 12 inches wide and 1½ inch thick. The Wall was 20 feet high, with towers and bastions at intervals about 50 feet high. At first there was no moat or ditch, and it will be understood that in order to protect the City from an attack of barbarians—Picts or Scots—it was enough to close the gates and to man the towers. The invaders had no ladders. - Remains of the Wall
The City was thus protected by a great wall pierced by a few gates, with bastions and towers. At the East End after the Norman Conquest rose the Great White Tower still standing. At the West End was a tower called Montfichet's Tower. - Part of the Roman Wall at Leicester

Houses were erected in course of time along the Bridge on either side like a street, but with intervals; and along the roadway in the middle were chain posts to protect the passengers. As the Bridge was only 40 feet wide the houses must have been small. But they were built out at the back overhanging the river, and the roadway itself was not intended for carts or wheeled vehicles. Remember that everything was brought to the City on pack horse or pack ass. The table of Tolls sanctioned by King Edward I. makes no mention of cart or waggon at all. Men on horseback and loaded horses can get along with a very narrow road. Perhaps we may allow twelve feet for the road which gives for the houses on either side a depth of 14 feet each. - The Tower of London
Of all the prisoners who suffered death at the termination of their captivity in the Tower, there is none whose fate was so cruel as that of Lady Jane Grey. Her story belongs to English history. Recall, when next you visit the Tower, the short and tragic life of this young Queen of a nine days' reign. - A Bed in the Reign of Henry III
- The Lepers Begging
Leprosy is supposed to have had its origin in Egypt: the laws laid down in the Book of Leviticus for the separation of lepers are stringent and precise: it was believed, partly, no doubt, on account of these statutes in the Book of the Jewish Law, that the disease was brought into Western Europe by the Crusaders; but this was erroneous, because it was in this country before the Crusaders. Thus the Palace of St. James stands upon the site of a lazar house founded before the Conquest for fourteen leprous maidens. - London before the Spire of St. Paul's was burned; showing the Bridge, Tower, Shipping, &c

The streets and lanes of London within the walls were very nearly the same as they are at present, except for the great thoroughfares constructed within the last thirty years. That is to say, when one entered at Lud Gate and passed through Paul's Churchyard, he found himself in the broad street, the market place of the City, known as Chepe. - A Sea-Fight

- General View of the Poughkeepsie Bridge
The new bridge at Poughkeepsie has three of these cantilevers, connected by two fixed spans, as shown in the illustration. The fixed spans have horizontal lower chords, and really extend beyond each pier and up the inclined portions, to where the bottom chord of the cantilever is horizontal. At these points the junctions between the spans are made, and arranged in such a way, by means of movable links, that expansion and contraction due to changes of temperature can take place. The fixed spans are 525 feet long. Their upper chord, where the tracks are placed, is 212 feet above water. These spans required stagings to build them upon. These stagings were 220 feet above water, and rested on piles, driven through 60 feet of water and 60 feet of mud, making the whole height of the temporary staging 332 feet, or within 30 feet of the height of Trinity Church steeple, in New York. The time occupied in building one of these stagings and then erecting the steel-work upon it was about four months. The cantilever spans were erected without any stagings at all below, and entirely from the two overhead travelling scaffolds, shown in the engraving. These scaffolds were moved out daily from the place of beginning over the piers, until they met in the centre. The workmen hoisted up the different pieces of steel from a barge in the river below and put them into place, using suspended planks to walk upon. The time saved by this method was so great that one of these spans of 548 feet long was erected in less than four weeks, or one-seventh of the time which would have been required if stagings had been used. - Erection of a Cantilever

The most notable invention of latter days in bridge construction is that of the cantilever bridge, which is a system devised to dispense with staging, or false works, where from the great depth, or the swift current, of the river, this would be difficult, or, as in the case of the Niagara River, impossible to make. The first design of which we have any record was that of a bridge planned by Thomas Pope, a ship carpenter of New York, who, in 1810, published a book giving his designs for an arched bridge of timber across the North River at Castle Point, of 2,400 feet span. Mr. Pope called this an arch, but his description clearly shows it to have been what we now call a cantilever. As was the fashion of the day, he indulged in a poetical description: "Like half a Rainbow rising on yon shore, While its twin partner spans the semi o'er, And makes a perfect whole that need not part Till time has furnish'd us a nobler art." Note : This bridge was never built - it would be impossible in wood. - View of Thomas Pope's Proposed Cantilever (1810)

Valleys and ravines are now crossed by viaducts of iron and steel, of which the Kinzua viaduct, illustrated here, is an example. A branch line from the Erie, connecting that system with valuable coal-fields, strikes the valley of the Kinzua, a small creek, about 15 miles southwest of Bradford, Pa. At the point suitable for crossing, this ravine is about half a mile wide and over 300 feet deep. At first it was proposed to run down and cross the creek at a low level by some of the devices heretofore illustrated in this article. But finally the engineering firm of Clarke, Reeves & Co. agreed to build the viaduct, shown above, for a much less sum than any other method of crossing would have cost. This viaduct was built in four months. It is 305 feet high and about 2,400 feet long. The skeleton piers were first erected by means of their own posts, and afterward the girders were placed by means of a travelling scaffold on the top, projecting over about 80 feet. No staging of any kind was used, nor even ladders, as the men climbed up the diagonal rods of the piers, as a cat will run up a tree. - Beginning a Tunnel
Tunnels are neither so long nor so frequent upon American railways as upon those of Europe. The longest are from two to two and a half miles long, except one, the Hoosac, about four miles. Sometimes they are unavoidable. The ridge called Bergen Hill, west of Hoboken, N. J., is a case in point. This is pierced by the tunnels of the West Shore, of the Delaware, Lackawanna, and Western, and of the Erie, the last two of which, are placed at different levels to enable one road to pass over the other. It is by our system of using sharp curves that we avoid tunnels. It may be said, in general terms, that American engineers have shown more skill in avoiding the necessity of tunnels than could possibly be shown in constructing them. When we are obliged to use tunnels, or to make deep cuttings in rocks, our labors are greatly assisted by the use of power-drills worked by compressed air and by the use of high explosives, such as dynamite, giant powder, rend-rock, etc. Rocks can now be removed in less than half the time formerly required, when ordinary blasting-powder was used in hand-drilled holes. - Steam Excavator
On the prairies of the West the road-bed is thrown up from ditches on each side, either by men with wheelbarrows and carts, or by means of a ditching-machine, which can move 3,000 yards of earth daily. In this case the track follows immediately after the embankment, and the men live in cars fitted up as boarding-shanties, and moved forward as fast as required. - Making an Embankment
After the railway line has been finally located, the next duty of the engineers is to prepare the work for letting. Land-plans are made, from which the right of way is secured. From the sections, the quantities are taken out. Plans of bridges and culverts are made; and a careful specification of all the works on the line is drawn up. The works are then let, either to one large contractor or to several smaller ones, and the labor of construction begins. The duties of the engineers are to stake out the work for the contractors, make monthly returns of its progress, and see that it is well done and according to the specifications and contract. The line is divided into sections, and an engineer, with his assistants, is placed in charge of each. Where the works are heavy, the contractors build shanties for their men and teams near the heavy cuttings or embankments. It is the custom to take out heavy cuttings by means of the machine called a steam shovel, which will dig as many yards in a day as 500 men. - Snow-sheds, Selkirk Mountains, Canadian Pacific
In all countries, old and new, mountainous and level, the rule should be to keep the level of track well above the surface of the ground, in order to insure good drainage and freedom from snow-drifts. The question of avoidance of obstruction by snow is a very serious one upon the Rocky Mountain lines, and they could not be worked without the device of snow-sheds—another purely American invention. There are said to be six miles of staunchly built snow-sheds on the Canadian Pacific and sixty miles on the Central Pacific Railway. The quantity of snow falling is enormous, sometimes amounting to 250,000 cubic yards, weighing over 100,000 tons, in one slide. It is stated by the engineers of the Canadian Pacific, that the force of the air set in motion by these avalanches has mown down large trees, not struck by the snow itself. Their trunks, from one to two feet in diameter, remain, split as if struck by lightning. - Engineers in Camp
A full surveying party consists of the front flag-man, with his corps of axe-men to cut away trees and bushes; the transit-man, who records the distances and angles of the line, assisted by his chain-men and flag-men; and lastly the leveller, who takes and records the levels, with his rod-men and axe-men. The chief of the party exercises a general supervision over all, and is sometimes assisted by a topographer, who sketches in his book the contours of the hills and direction and size of the watercourses. One tent contains the cook, the commissary, and the provisions; another tent or two the working party, and another the superior engineers, with their drawing instruments and boards. In a properly regulated party the map and profile of the day's work should be plotted before going to bed, so as to see if all is right. If it turns out that the line can be improved and easier grades got, or other changes made, now is the time to do it. - A Switchback
Another American invention is the switchback. By this plan the length of line required to ease the gradient is obtained by running backward and forward in a zigzag course, instead of going straight up the mountain. As a full stop has to be made at the end of every piece of line, there is no danger of the train running away from its brakes. This device was first used among the hills of Pennsylvania over forty years ago, to lower coal cars down into the Nesquehoning Valley. It was afterwards used on the Callao, Lima, and Oroya Railroad in Peru, by American engineers, with extraordinary daring and skill. It was employed to carry the temporary tracks of the Cascade Division of the Northern Pacific Railroad over the "Stampede" Pass, with grades of 297 feet per mile, while a tunnel 9,850 feet long was being driven through the mountains. - A Sharp Curve—Manhattan Elevated Railway, 110th Street, New York
Equally valuable improvements were made in cars, both for passengers and freight. Instead of the four-wheeled English car, which on a rough track dances along on three wheels, we owe to Ross Winans, of Baltimore, the application of a pair of four-wheeled swivelling trucks, one under each end of the car, thus enabling it to accommodate itself to the inequalities of a rough track and to follow its locomotive around the sharpest curves. There are, on our main lines, curves of less than 300 feet radius, while, on the Manhattan Elevated, the largest passenger traffic in the world is conducted around curves of less than 100 feet radius. There are few curves of less than 1,000 feet radius on European railways. - Locomotive of To-day

- Reconstruction of coal-forming swamp
Coal is a combustible rock that was formed by the accumulation and partial decay of vegetation. When coal was forming millions of years ago, most of the state was a low coastal plain bordered on the west and southwest by a shallow sea. A large variety of plants grew in great swamps which covered this coastal plain. When the plants died, they accumulated in the swamps to form thick masses of peat that were eventually covered by shallow seas and buried beneath mud and sand. Periodically, the region was above sea level, new swamps developed, new peat deposits accumulated, and more sediments were laid down. This process occurred repeatedly until over 3,000 feet of sediments had been deposited. Then the sediments were slowly compacted and hardened so that sandstones, shales, limestones, and coals were formed. - Extent of the main glacial advances

The narrow cruciform loophole, called by architects ' Arbalestina,' which is usually to be seen in the masonry of a mediaeval fortress, was designed for the special use of crossbowmen in repelling an assault. To enable the crossbow, or longbow, to be aimed to the right or left through a loophole, the aperture was greatly widened out on the inside face of the perforated wall. - Crossbowmen

Of this plate Valturius quaintly writes: ' When everything is cleared for navigation before the charge is made upon the enemy, it is well that those who are about to engage the foe should first practise in port, and grow accustomed to turn the tiller in calm water, to get ready the iron grapples and hooked poles, and sharpen the axes and scythes at their ends. The soldiers should learn to stand firm upon the decks and keep their footing, so that what they learn in sham fight they may not shrink from in real action. - She contemplates the cloister
