"The bridge is down!" cried Jack, drawing rein at the verge of the stream. "Indians!"

"Or Xuarez!" added Philip, gravely. "I suspect the latter. Indians are not sufficiently civilised to destroy bridges."

The débris of the bridge impeded the current, and here the waters boiled white amid the black ruins. Jagged posts stretched in black rows to the other side of the stream, but there was no foothold left by which they could cross dry-shod.

"Swim!" said Tim, briefly, and sent his steed down the bank. The others followed, and in a few minutes the surface of the stream was dotted with black figures. The river being sluggish, with little or no current, they found no difficulty in crossing, and speedily gained the opposite bank. Climbing the slope on to the flat land, they regained the line of road, and once more urged their horses to full speed.

The moon arose, round and bright, making the whole scene cheerful with her kindly light. The fugitives looked back, but could see no sign of pursuit. Even the town had vanished. Behind, before, lay nothing but the immensity of the plains. It was as though they were in the midst of a leaden-hued sea. The appearance of the moon raised their spirits, and they redoubled their speed. Centeotl was now comparatively near. The ground began to show signs of cultivation. Hedges of cacti ran along the sides of the road, bearing fleshly looking flowers of tawny gold. Right and left stretched gardens, environing country houses, and before them arose a white line of wall.

"Centeotl!" cried Don Sebastian, pushing forward.

The gates were closed owing to the fear of the townspeople lest the Indians should make a night attack. De Ahumada galloped on ahead, and reined his horse immediately under the walls. At intervals the sentinels called the one to the other, "Centinella alerte," to show that they were awake. The noise of the approaching horses brought them to the walls.

"Quien vive!"

"Amigos! From Janjalla."

The red light of torches glared from the low battlements, and in a few minutes the gates were opened. The officer in charge recognised Don Sebastian, and was much depressed at learning Janjalla had fallen.
