"I knew it was my task to keep the negro from getting away," continued the little Mexican excitedly. "So I leaped up, extended my forefinger and rushed at him. But thees Evarts—-hees feest catch me between the eyes. I do not have to guess the spot where he struck me, Senor, for I can feel it yet. Down I went, and knew no more. When next I opened my eyes I found myself lying in the middle of a theecket of bushes. I theenk, perhaps, the scoundrels believed they had killed me, and so they hid my body. But I have fool' them. I am still alive—-much alive!"

"What did you do when you came to, Nicolas?"

"Senor," protested the Mexican, "there was no more need of me. You had gone after men. Eef you came back, you have many men with you, so you do not need me. For that reason I come home."

Even in the dark the young engineer could "feel" Nicolas's shudder. Tom could not repress a smile that threatened to become a chuckle.

"I was varee sleepy," continued Nicolas, "and so I lay down. I forgot to undress, or even to take off my shoes. I fall asleep, and I dream much. I see the big negro again, and I dream that I have more fight with heem. Then, when you pull my foot, I wake up in one gr-rand sweat, for I theenk the big black attack me once more. I am glad—-so glad that it is not true."

"Nicolas," cried Tom, "you have done fighting enough for one night. Yet tell me, how did you happen to be at hand to-night in time to save me from Mr. Sambo Ebony?"

"Because I see you start away to-night," replied Nicolas, "an' I see that you go alone. I know that you mos' likely run into trouble, an' so I follow you. Sure enough, Senor, you find trouble—-and I heet heem with my finger!"

"You surely did 'hit him with your finger,' Nicolas," laughed Tom, grasping the little Mexican's hand and wringing it. "But now come outside. I had sent for the police to find you, and now I must show them that you are already found."

Together they went out on the porch. Tom explained the situation.

"Then you don't need us, after all?" asked one of the policemen.
