d Lord Ralles is showing us how to--"

My speech was interrupted. "Bang! bang!" challenged another "express,"
the shots so close together as to be almost simultaneous. "Crack!
crack! crack!" retorted the Winchesters, and from the fact that
silence followed I drew a clear inference. I said to myself, "That is
an end of poor John Bull."

CHAPTER III

A NIGHT'S WORK ON THE ALKALI PLAINS

I hurried Miss Cullen into the car, and, after bolting the rear door,
took down my Winchester from its rack.

"I'm going forward," I told her, "and will tell my darkies to bolt the
front door: so you'll be as safe in here as in Chicago."

In another minute I was on my front platform. Dropping down between
the two cars, I crept along beside--indeed, half under--Mr. Cullen's
special. After my previous conclusion, my surprise can be judged when
at the farther end I found the two Britishers and Albert Cullen,
standing there in the most exposed position possible. I joined them,
muttering to myself something about Providence and fools.

"Aw," drawled Cullen, "here's Mr. Gordon, just too late for the sport,
by Jove."

"Well," bragged Lord Ralles, "we've had a hand in this deal, Mr.
Superintendent, and haven't been potted. The scoundrels broke for
cover the moment we opened fire."

By this time there were twenty passengers about our group, all of them
asking questions at once, making it difficult to learn just what had
happened; but, so far as I could piece the answers together, the
poker-players' curiosity had been aroused by the long stop, and,
looking out, they had seen a single man with a rifle standing by the
engine. Instantly arming themselves, Lord Ralles let fly both barrels
at him, and in turn was the target for the first four shots I had
heard. The shooting had brought the rest of the robbers tumbling off
the cars, and the captain and Cullen had fired the rest of the shots
at them as they scattered, I didn't stop to hear more, but went
forward to see what the road agents had got away with.

I found the express agent tied hand and foot in the corner of his car,
and, telling a brakeman who had followed me to set him at liberty, I
turned my attention to the safe. That the diversion had not come a
moment too soon was shown by the dynamite cartridge already in place,
and by the fuse that lay on the floor, as if dropped suddenly. But the
safe was intact.

Passing into the mail-car, I found the clerk tied to a post, with a
