The fires had dwindled now.  Where flames had been there were now streamers of smoke; but the countless ruins of shattered and gutted houses and blasted and blackened trees that the night had hidden stood out now gaunt and terrible in the pitiless light of dawn.  Yet here and there some object had had the luck to escape--a white railway signal here, the end of a greenhouse there, white and fresh amid the wreckage.  Never before in the history of warfare had destruction been so indiscriminate and so universal. And shining with the growing light of the east, three of the metallic giants stood about the pit, their cowls rotating as though they were surveying the desolation they had made.")
			TEXT("\n\n")
			TEXT("It seemed to me that the pit had been enlarged, and ever and again puffs of vivid green vapour streamed up and out of it towards the brightening dawn--streamed up, whirled, broke, and vanished.")

			TEXT("The artilleryman agreed with me that the house was no place to stay in.  He proposed, he said, to make his way Londonward, and thence rejoin his battery--No. 12, of the Horse Artillery.  My plan was to return at once to Leatherhead; and so greatly had the strength of the Martians impressed me that I had determined to take my wife to Newhaven, and go with her out of the country forthwith.  For I already perceived clearly that the country about London must inevitably be the scene of a disastrous struggle before such creatures as these could be destroyed.")
			TEXT("\n\n")
			TEXT("Between us and Leatherhead, however, lay the third cylinder, with its guarding giants.  Had I been alone, I think I should have taken my chance and struck across country.  But the artilleryman dissuaded me: \"It's no kindness to the right sort of wife,\" he said, \"to make her a widow\"; and in the end I agreed to go with him, under cover of the woods, northward as far as Street Cobham before I parted with him. Thence I would make a big detour by Epsom to reach Leatherhead.")
			TEXT("\n\n")
			TEXT("I should have started at once, but my companion had been in active service and he knew better than that.  He made me ransack the house for a flask, which he filled with whiskey; and we lined every available pocket with packets of biscuits and slices of meat.  Then we crept out of the house, and ran as quickly as we could down the ill-made road by which I had come overnight.  The houses seemed deserted. In the road lay a group of three charred bodies close together, struck dead by the Heat-Ray; and here and there were things that people had dropped--a clock, a slipper, a silver spoon, and the like poor valuables.  At the corner turning up towards the post office a little cart, filled with boxes and furniture, and horseless, heeled over on a broken wheel.  A cash box had been hastily smashed open and thrown under the debris.")
			TEXT("\n\n")
			TEXT("Except the lodge at the Orphanage, which was still on fire, none of the houses had suffered very greatly here.  The Heat-Ray had shaved the chimney tops and passed.  Yet, save ourselves, there did not seem to be a living soul on Maybury Hill.  The majority of the inhabitants had escaped, I suppose, by way of the Old Woking road--the road I had taken when I drove to Leatherhead--or they had hidden.")
			TEXT("\n\n")
			TEXT("We went down the lane, by the body of the man in black, sodden now from the overnight hail, and broke into the woods at the foot of the hill.  We pushed through these towards the railway without meeting a soul.  The woods across the line were but the scarred and blackened ruins of woods; for the most part the trees had fallen, but a certain proportion still stood, dismal grey stems, with dark brown foliage instead of green.")
			TEXT("\n\n")
			TEXT("On our side the fire had done no more than scorch the nearer trees; it had failed to secure its footing.  In one place the woodmen had been at work on Saturday; trees, felled and freshly trimmed, lay in a clearing, with heaps of sawdust by the sawing-machine and its engine. Hard by was a temporary hut, deserted.  There was not a breath of wind this morning, and everything was strangely still.  Even the birds were hushed, and as we hurried along I and the artilleryman talked in whispers and looked now and again over our shoulders.  Once or twice we stopped to listen.")

They do not seem to have aimed at extermination so much as at complete demoralisation and the destruction of any opposition.  They exploded any stores of powder they came upon, cut every telegraph, and wrecked the railways here and there.  They were hamstringing mankind.  They seemed in no hurry to extend the field of their operations, and did not come beyond the central part of London all that day.  It is possible that a very considerable number of people in London stuck to their houses through Monday morning.  Certain it is that many died at home suffocated by the Black Smoke.")

Steamboats and shipping of all sorts lay there, tempted by the enormous sums of money offered by fugitives, and it is said that many who swam out to these vessels were thrust off with boathooks and drowned.  About one o'clock in the afternoon the thinning remnant of a cloud of the black vapour appeared between the arches of Blackfriars Bridge.  At that the Pool became a scene of mad confusion, fighting, and collision, and for some time a multitude of boats and barges jammed in the northern arch of the Tower Bridge, and the sailors and lightermen had to fight savagely against the people who swarmed upon them from the riverfront.  People were actually clambering down the piers of the bridge from above.")

My brother, keeping watch beside the women in the chaise in a meadow, saw the green flash of it far beyond the hills.  On Tuesday the little party, still set upon getting across the sea, made its way through the swarming country towards Colchester. The news that the Martians were now in possession of the whole of London was confirmed.  They had been seen at Highgate, and even, it was said, at Neasden.  But they did not come into my brother's view until the morrow.")

Farmers were out to defend their cattle-sheds, granaries, and ripening root crops with arms in their hands.  A number of people now, like my brother, had their faces eastward, and there were some desperate souls even going back towards London to get food. These were chiefly people from the northern suburbs, whose knowledge of the Black Smoke came by hearsay.  He heard that about half the members of the government had gathered at Birmingham, and that enormous quantities of high explosives were being prepared to be used in automatic mines across the Midland counties.")
			TEXT("\n\n")
			TEXT("He was also told that the Midland Railway Company had replaced the desertions of the first day's panic, had resumed traffic, and was running northward trains from St. Albans to relieve the congestion of the home counties.  There was also a placard in Chipping Ongar announcing that large stores of flour were available in the northern towns and that within twenty-four hours bread would be distributed among the starving people in the neighbourhood.  But this intelligence did not deter him from the plan of escape he had formed, and the three pressed eastward all day, and heard no more of the bread distribution than this promise.  Nor, as a matter of fact, did anyone else hear more of it.  That night fell the seventh star, falling upon Primrose Hill.  It fell while Miss Elphinstone was watching, for she took that duty alternately with my brother.  She saw it.")
			TEXT("\n\n")
			TEXT("On Wednesday the three fugitives--they had passed the night in a field of unripe wheat--reached Chelmsford, and there a body of the inhabitants, calling itself the Committee of Public Supply, seized the pony as provisions, and would give nothing in exchange for it but the promise of a share in it the next day.  Here there were rumours of Martians at Epping, and news of the destruction of Waltham Abbey Powder Mills in a vain attempt to blow up one of the invaders.")
			TEXT("\n\n")
			TEXT("People were watching for Martians here from the church towers.  My brother, very luckily for him as it chanced, preferred to push on at once to the coast rather than wait for food, although all three of them were very hungry.  By midday they passed through Tillingham, which, strangely enough, seemed to be quite silent and deserted, save for a few furtive plunderers hunting for food.  Near Tillingham they suddenly came in sight of the sea, and the most amazing crowd of shipping of all sorts that it is possible to imagine.")

At the sight of the Martian's collapse the captain on the bridge yelled inarticulately, and all the crowding passengers on the steamer's stern shouted together.  And then they yelled again.

She headed straight for a second Martian, and was within a hundred yards of him when the Heat-Ray came to bear.  Then with a violent thud, a blinding flash, her decks, her funnels, leaped upward.  The Martian staggered with the violence of her explosion, and in another moment the flaming wreckage, still driving forward with the impetus of its pace, had struck him and crumpled him up like a thing of cardboard.  My brother shouted involuntarily.  A boiling tumult of steam hid everything again.")

The fleet of refugees was scattering to the northeast; several smacks were sailing between the ironclads and the steamboat.  After a time, and before they reached the sinking cloud bank, the warships turned northward, and then abruptly went about and passed into the thickening haze of evening southward.  The coast grew faint, and at last indistinguishable amid the low banks of clouds that were gathering about the sinking sun.")

My brother strained his eyes. Something rushed up into the sky out of the greyness--rushed slantingly upward and very swiftly into the luminous clearness above the clouds in the western sky; something flat and broad, and very large, that swept round in a vast curve, grew smaller, sank slowly, and vanished again into the grey mystery of the night.  And as it flew it rained down darkness upon the land.")

This will give you full customization in how your text or widget is styled. \n\nBesides the power of Decorators the SRichTextBlock comes equipped with Margin support, Left-Center-Right Text Justification, a Line Height Scalar and Highlighting.\n\n<RichText.Header>How does the markup work?</>\n\nWell the markup parser is customizable so you can adjust the markup anyway you'd like by providing your own parser.  The parser that comes with Slate though uses a syntax very similar to xml.\n\n        \u2022  &lt;TextBlockStyleName>Your text content&lt;/>\n        \u2022  &lt;img src=\"SlateBrushStyleName\"/>\n        \u2022  &lt;a id=\"YourCustomId\"/>Your hyperlink text&lt;/>\n\nIf you ever want to use the markup syntax as actual text you can escape the markup using xml style escapes. For example:\n\n        \u2022  <    &amp;lt;\n        \u2022  >    &amp;gt;\n        \u2022  \"     &amp;quot;\n\nBut you only need to escape these characters when a set of them match actual syntax so this isn't generally an issue.\n\n<RichText.Header>Are there any catches?</>\n\nThere are still plenty of things the SRichTextBlock doesn't currently support. The most notable lacking feature is not having the ability to flow text around images or widgets. ") )
