"How?" asked Jack, who was more than interested. "You fell from your seat into the water."

"I did that. The cart war left on the edge of the ledge, as I've already said, and the river was jest about washing the floor boards. I floundered under the surface for a bit, and then got my feet safe on ter the ledge. But when I lifted my head to take a breath it came bump up agin the floor boards. I war clear under the wagon, and, as luck would have it, there was jest enough space there to allow me to breathe. Guess them four critters thought I was drownded, fer they rid up to the wagon laughing fit ter bust.

"'That 'ere shot cleared him out fine,' I heard one of them shout. 'Git to their heads, mate, and take them along the ford. We ain't out of this muss yet. Joe, ride ahead, and make sure ye're on the ledge. Now that we've got the gold it won't do ter lose it. I'll keep close handy to the cart. The old man'll want shootin'.'

"That's the sort of ruffians they was," explained Tom. "They didn't think no more of shootin' a man then I think of eatin' dinner. And it didn't make no difference to them whether it war a boy their bullets hit, or a man. But I war under the wagon, and though I had been scared I warn't done with, not by a heap. Yer must understand that gold dust are heavy stuff to carry, but it don't take up a heap of room, so thar was plenty o' space left fer us in the wagon. Then, same as we have here, some of the boards was kept loose on purpose. Yer see, out on the plains, when ye've a load, yer often want to carry odds and ends slung to the wagon. Thar's a pail fer watering the mules, a cooking pot, and sich like things. Sometimes they're jest slung to hooks screwed into the bottom boards. But Uncle had his own ideas of comfort and of doin' things, and I reckon he ought to know what was right, seem' he'd been on the road so long. His idea was to have a tray slung under the centre of the wagon by means of four short lengths of chain, and the bottom boards above carried loose, so as you could haul up anything you wanted from the tray. Wall now, in course, seeing that we had to cross the river, I had removed every stick from that tray. It come bump up agin me as I crouched below the wagon, and, as those men moved the team along, I jest climbed on to the tray and rose my head through the boards of the wagon. It war as good as a play. There were them critters thinkin' that I was floatin' down the river. And there was me, half in the wagon, extry lively, wonderin' hard what ter do. It war Uncle's shooter that decided the matter. He was lying close handy to the opening, as pale as death, with his revolver on the boards beside him.

"'Yer own's drenched by the river,' I said to myself, feeling for the shooter I carried in my belt. 'His is all right. Take it, and go fer them critters.' Wall, I hopped clean into the wagon then, waited a bit till we were getting close to the far bank, fer the robbers war guiding the team all the while, and war going forward as slow as ef it war to a funeral. Then I lifted the edge of the tilt, took aim at the chap riding nearest, and pulled the trigger. Reckon he war killed outright. Anyway, he plumped into the water, and none of us saw him agin. But you kin guess that thar war a ruction. Them fellers thought that they had the thing all to themselves, and then, all of a sudden, one of their number was wiped out. They wasn't cowards, to say the best of them, and the three who war left gave up minding the mules and came ridin' their hosses back to the wagon, sending a bullet or so to show that they war coming. Yer don't think I waited for 'em, do yer?"

Tom asked the question with a knowing wag of his head.

"Not much," he proceeded, as Jack showed his doubt. "I knew ef I stayed in the wagon they'd riddle me before I could wink: same as you guessed that thet fellow in the railway carriage would shoot yer ef yer rose your head above the window. Thar was Uncle, too. Ef I got shot where I was, he was certain ter be found and an end made of him. I kinder guessed the whole thing in a flash, and then dived through the boards of the wagon, on to the tray below, and then into the river. There was eight inches or more of air space beneath the boards by then, fer the ledge was rising, and ef a man had stood in the river and stooped, so as to get a view, he could have seen me fer certain. But them critters was on horseback, and I reckon they never gave a thought to the under part of the wagon. Anyway, they rode up with every intention of pulling the tilt aside and shooting me the moment they could clap eyes on my figure. And I disappointed 'em. I jest waded to the edge of the wagon, fixed myself inside one of the wheels, and when they was within five feet of me let go with my pistol. It fixed 'em sure. They wasn't expecting anything from underneath the wagon, same as that critter in the train warn't expecting nothing from the roof. My bullet must have struck one of the hosses, and the mad plunging of the beast didn't help matters for them. Then a second bullet winged one of the men, and in a moment they went flying. Gee! It makes me laugh now to think of the muss they got into. The bank war on our left, and a short cut to it took yer into deep water. They war properly scared, and, like people in a similar condition, they made fer safety by what seemed ter be the quickest route. In two seconds their hosses was swimming, and before they managed to reach the bank one at least of the villains had had a narrow squeak fer his life. As fer me, I climbed on to the box, took up the reins, and sent the mules flyin' to the bank. But I didn't stay there. I turned 'em, and came back over the water. Yer see, the three robbers was left on the far side, and ef they wanted to attack again they had to cross the ford there in full view, or had to gallop up to the other ford. In any case it would give me time to fix matters up a little, and pay some attention to Uncle."

"You saved him," said Jack enthusiastically. "He must have been proud of you. You were only a boy, I must remember."

"He war a peppery feller," laughed Tom. "He came to his senses five minutes later, and fer a time I guess he thought the cart and the gold were taken. Then he reckoned he'd had a baddish dream. It warn't till the following day thet I told him."

"And then?" asked Jack.
