Banney were busy with the last things to be done before we started. Aunty Boone sat on a pile of pelts inside the store, smoking her pipe. Beverly and Mat stood waiting in the big doorway, while I sat on a barrel outside, because my ankle was still a bit stiff. A crowd had gathered before the store to see us off. It was not such a company as the soldier-men at the fort. The outlaw, the loafer, the drunkard, the ruffian, the gambler, and the trickster far outnumbered the stern-faced men of affairs. When the balance turns the other way the frontier disappears. Mingling with these was a pale-faced invalid now and then, with the well-appointed new arrivals from the East.

"What are we waiting for, Bev?" I asked, as the street filled with men.

"Got to get another span of moolies for our baby-cart. Uncle Esmond hadn't counted on the nurse and the cook going, you know, but he rigged this littler wagon out in a twinkle."

"That's the family carriage, drawn by spirited steeds. Us children are to ride in it, with Daniel Boone to help with the driving," Mat added.

Just then Esmond Clarenden appeared at the door.

"How soon do you start, Clarenden?" some one in the crowd inquired.

"Just as soon as I can get a pair of well-broken mules," he replied. "I'm looking for the man who has them to sell quick. I'm in a hurry."

"What's your great rush?" a well-dressed stranger asked. "They tell me things look squally out West."

"All the more reason for my being in a hurry then," Uncle Esmond returned.

"They ain't but three men of you, is they? What do you want of more mules?" put in an inquisitive idler of the trouble-loving class who sooner or later turn arguments into bitter brawls.

"These three children and the cook in there have this wagon. They are all fair drivers, if I can get the right mules," my uncle said.

Women and children did not cross the plains in those days, nor could public welfare allow that so valuable a piece of property as Aunty Boone would be in the slave-market should be lost to commerce, and the storm of protest that followed would have overcome a less determined man. It was not on account of sympathy for the weak and defenseless that called out all this abuse, but the lawless spirit that stirs up a mob on the slightest excuse.

I slid away to the door, where, with Mat and Beverly, I watched Esmond Clarenden, who was listening with his good-natured smile to all of that loud street talk.

"No man's life is insurable in these troublesome times, with our troops right now down in Mexico," a suave Southern trader urged. "Better sell your slave and put that nice little gal in a boardin'-school somewhere in the South."

"I'll give you a mighty good bargain for that wench, Clarenden. She might be worth a clare fortune in New Orleans. What d'ye say to a cool thousand?" another man declared, with a slow. Southern drawl.

Aunty Boone took the pipe from her lips and looked at the stranger.

"Y'would!" she grunted, stretching her big right hand across her lap, like a huge paw with claws ready underneath.

"Them plains Injuns never was more hostile than they air right now. I just got in from the mountains an' I know. An' they're bein' set on by more hostile Mexican devils, and political intrigs," a bearded mountaineer trapper argued.

"'Sides all that," interposed the suave Southern gentleman, "it's too early in the spring. Freightin's bound to be delayed by rains--and a nice little gal with only a nigger--" He was not quite himself, and he did not try to say more.

"Seems like some of these gentlemen consider you are some sort of a fool," a tall, lean Yankee youth observed, as he listened to the babble.

I had climbed back on the barrel again to see the crowd better, and I stared at the last speaker. His voice was not unpleasant, but he appeared pale and weak and spiritless in that company of tanned, rugged men. Evidently he was an invalid in search of health. We children had seen many invalids, from time to time, at the fort harmless folk, who came to fuss, and stayed to flourish, in our gracious land of the open air.

"You are a dam' fool," roared a big drunken loafer from the edge of the crowd. "An' I'd lick you in a minnit if you das step into the middle of the street onct. Ornery sneak, to take innocent children into such perils. Come on out here, I tell ye!"

A growl followed these words. Many men in that company were less than half sober, and utterly irresponsible.

"Le's jes' hang the fool storekeepin' gent right now; an' make a free-fur-all holiday. I'll begin," the drunken ruffian bawled. He was of the sort that always leads a mob.

The growl deepened, for blood-lust and drunkenness go together.

Terrified for my uncle's safety, I stood breathless, staring at the evil-faced crowd of men going suddenly mad, without excuse. At the farthest edge of the insipient mob, sitting on his horse and watching my uncle's face intently, was the very Mexican whom I had twice seen at Fort Leavenworth. At the drunken rowdy's challenge, I thought that he half-lifted a threatening hand. But Esmond Clarenden only smiled, with a mere turn of his head as if in disapproval. In that minute I learned my first lesson in handling ruffians. I knew that my uncle was not afraid, and because of that my faith in his power to take care of himself came back.

"I want to leave here in half an hour. If you have any good plains-broke mules you will sell for cash, I can do business with you right now. If not, the sooner you leave this place the better."

He lifted his small, shapely hand unclenched, his good-natured smile and gentlemanly bearing unchanged, but his low voice was stronger than all the growls of the crowd that fell back like whipped dogs.

As he spoke a horse-dealer, seeing the gathering before the store, came galloping up.

"I'm your man. Money talks so I can understand it. Wait five minutes and ten seconds and I'll bring a whole strand of mules."

A rattling of wagons and roar of voices at the far end of the street told of the arrival of a company coming in from the wharf at Westport, and the crowd whirled about and made haste toward the next scene of interest.

Only two men remained behind, the tall New England youth and the Mexican on the farther side of the street sitting motionless on his horse. A moment later he was gone, and the street was empty save for the pale-faced invalid who had come over to the doorway where Mat and Beverly and I waited together.

"Why don't you youngsters stay home with your mother, or is she going with you?" he asked, a gleam of interest lighting his dull face as he looked at Mat Nivers.

"We haven't any of us got a mother," Mat replied, timidly, lifting her gray eyes to his.

"Mother! Ain't you all one family?" the young man questioned in surprise.

"No, we are three orphan children that Uncle Esmond has adopted all our lives, I guess." Beverly informed him.

A wave of sympathy swept over his face.

"You poor, lonely, unhappy cubs! You've never had a mother to love you!" he exclaimed, in kindly pity.

"We aren't poor nor lonely nor unhappy. We have always had Uncle Esmond and we didn't need a mother," I exclaimed, earnestly.

The young man stared at me as I spoke. "What's he, a bachelor or married man?" he inquired.

"He couldn't be married and keep us, I reckon, and he's taking us with him so nothing will happen to us while he's gone. He's really truly Bev's uncle and mine, but he's just the same as uncle to Mat, who hasn't anybody else," I declared, enthusiastically. Uncle Esmond was my pride, and I meant that he should be fully appreciated.

The Yankee gazed at all three of us, his eyes resting longest on Mat's bright face. The listlessness left his own that minute and a new light shone on his
