They followed the paths down to the gates of the walls, where two pairs of soldiers rushed out and seized their horses by the bridles. These soldiers all seemed to be twins, or at least mates, and each one of each pair was as like the other as are two peas growing in the same pod. If one had a red nose the other's was red in the same degree, and the soldiers that held the bridles of Nerle's horse both had their left eyes bruised and blackened, as from a blow of the same force.

These soldiers, as they looked upon Nerle and the prince, seemed fully as much astonished and certainly more frightened than their prisoners. They were dressed in bright yellow uniforms with green buttons, and the soldiers who had arrested the prince had both torn their left coat-sleeves and had patches of the same shape upon the seats of their trousers.

"How dare you stop us, fellows?" asked the prince, sternly.

The soldiers holding his horse both turned and looked inquiringly at the soldiers holding Nerle's horse; and these turned to look at a double captain who came out of two doors in the wall and walked up to them.

"Such things were never before heard of!" said the two captains, their startled eyes fixed upon the prisoners. "We must take them to the Ki and the Ki-Ki."

"Why so?" asked Prince Marvel.

"Because," replied the officers, "they are our rulers, under grace of the High Ki, and all unusual happenings must be brought to their notice. It is our law, you know--the law of the Kingdom of Twi."

"Very well," said Marvel, quietly; "take us where you will; but if any harm is intended us you will be made to regret it."

"The Ki and the Ki-Ki will decide," returned the captains gravely, their words sounding at the same instant.

And then the two pairs of soldiers led the horses through the double streets, the captains marching ahead with drawn swords, and crowds of twin men and twin women coming from the double doors of the double houses to gaze upon the strange sight of men and horses who were not double.
