"It isn't ichthyology; it is dogmatics, which is still more difficult and tangled up. Dogmatics always are."

"Dogmatics is quite beyond me, quite; so I am not competing. But on general principles it is my opinion that a colt out of a coyote and a wild-cat is no square dog, but doubtful. That is my hand, and I stand pat."

"Well, it is as far as I can go myself, and be fair and conscientious. I have always regarded him as a doubtful dog, and so has Potter. Potter is the great Dane. Potter says he is no dog, and not even poultry--though I do not go quite so far as that.

"And I wouldn't, myself. Poultry is one of those things which no person can get to the bottom of, there is so much of it and such variety. It is just wings, and wings, and wings, till you are weary: turkeys, and geese, and bats, and b.u.t.terflies, and angels, and gra.s.shoppers, and flying-fish, and--well, there is really no end to the tribe; it gives me the heaves just to think of it. But this one hasn't any wings, has he?"

"No."

"Well, then, in my belief he is more likely to be dog than poultry.

I have not heard of poultry that hadn't wings. Wings is the SIGN of poultry; it is what you tell poultry by. Look at the mosquito."

"What do you reckon he is, then? He must be something."

"Why, he could be a reptile; anything that hasn't wings is a reptile."

"Who told you that?"

"n.o.body told me, but I overheard it."

"Where did you overhear it?"

"Years ago. I was with the Philadelphia Inst.i.tute expedition in the Bad Lands under Professor Cope, hunting mastodon bones, and I overheard him say, his own self, that any plantigrade circ.u.mflex vertebrate bacterium that hadn't wings and was uncertain was a reptile. Well, then, has this dog any wings? No. Is he a plantigrade circ.u.mflex vertebrate bacterium? Maybe so, maybe not; but without ever having seen him, and judging only by his illegal and spectacular parentage, I will bet the odds of a bale of hay to a bran mash that he looks it. Finally, is he uncertain? That is the point--is he uncertain? I will leave it to you if you have ever heard of a more uncertainer dog than what this one is?"

"No, I never have."

"Well, then, he's a reptile. That's settled."

"Why, look here, whatsyourname"

"Last alias, Mongrel."

"A good one, too. I was going to say, you are better educated than you have been pretending to be. I like cultured society, and I shall cultivate your acquaintance. Now as to Shekels, whenever you want to know about any private thing that is going on at this post or in White Cloud's camp or Thunder-Bird's, he can tell you; and if you make friends with him he'll be glad to, for he is a born gossip, and picks up all the t.i.ttle-tattle. Being the whole Seventh Cavalry's reptile, he doesn't belong to anybody in particular, and hasn't any military duties; so he comes and goes as he pleases, and is popular with all the house cats and other authentic sources of private information. He understands all the languages, and talks them all, too. With an accent like gritting your teeth, it is true, and with a grammar that is no improvement on blasphemy--still, with practice you get at the meat of what he says, and it serves. . . Hark! That's the reveille. . . .

[THE REVEILLE]

"Faint and far, but isn't it clear, isn't it sweet? There's no music like the bugle to stir the blood, in the still solemnity of the morning twilight, with the dim plain stretching away to nothing and the spectral mountains slumbering against the sky. You'll hear another note in a minute--faint and far and clear, like the other one, and sweeter still, you'll notice. Wait . . . listen. There it goes! It says, 'IT IS I, SOLDIER--COME!' . . .

[SOLDIER BOY'S BUGLE CALL]

. . . Now then, watch me leave a blue streak behind!"

CHAPTER VII--SOLDIER BOY AND SHEKELS

"Did you do as I told you? Did you look up the Mexican Plug?"

"Yes, I made his acquaintance before night and got his friendship."

"I liked him. Did you?"

"Not at first. He took me for a reptile, and it troubled me, because I didn't know whether it was a compliment or not. I couldn't ask him, because it would look ignorant. So I didn't say anything, and soon liked him very well indeed. Was it a compliment, do you think?"

"Yes, that is what it was. They are very rare, the reptiles; very few left, now-a-days."

"Is that so? What is a reptile?"

"It is a plantigrade circ.u.mflex vertebrate bacterium that hasn't any wings and is uncertain."

"Well, it--it sounds fine, it surely does."

"And it IS fine. You may be thankful you are one."

"I am. It seems wonderfully grand and elegant for a person that is so humble as I am; but I am thankful, I am indeed, and will try to live up to it. It is hard to remember. Will you say it again, please, and say it slow?"

"Plantigrade circ.u.mflex vertebrate bacterium that hasn't any wings and is uncertain."

"It is beautiful, anybody must grant it; beautiful, and of a n.o.ble sound. I hope it will not make me proud and stuck-up--I should not like to be that. It is much more distinguished and honorable to be a reptile than a dog, don't you think, Soldier?"

"Why, there's no comparison. It is awfully aristocratic. Often a duke is called a reptile; it is set down so, in history."

"Isn't that grand! Potter wouldn't ever a.s.sociate with me, but I reckon he'll be glad to when he finds out what I am."

"You can depend upon it."

"I will thank Mongrel for this. He is a very good sort, for a Mexican Plug. Don't you think he is?"

"It is my opinion of him; and as for his birth, he cannot help that. We cannot all be reptiles, we cannot all be fossils; we have to take what comes and be thankful it is no worse. It is the true philosophy."

"For those others?"

"Stick to the subject, please. Did it turn out that my suspicions were right?"

"Yes, perfectly right. Mongrel has heard them planning. They are after BB's life, for running them out of Medicine Bow and taking their stolen horses away from them."

"Well, they'll get him yet, for sure."

"Not if he keeps a sharp look-out."

"HE keep a sharp lookout! He never does; he despises them, and all their kind. His life is always being threatened, and so it has come to be monotonous."

"Does he know they are here?"

"Oh yes, he knows it. He is always the earliest to know who comes and who goes. But he cares nothing for them and their threats; he only laughs when people warn him. They'll shoot him from behind a tree the first he knows. Did Mongrel tell you their plans?"

"Yes. They have found out that he starts for Fort Clayton day after to-morrow, with one of his scouts; so they will leave to- morrow, letting on to go south, but they will fetch around north all in good time."
