"See that flash between those two hills?" said Rhoda, reining in her mount.
They gathered about her, looking where she aimed the glasses.
Walter exclaimed:
"I see the flash! It isn't the sun shining on guns, is it?"
"Nonsense!" cried Nan Sherwood.
"No-o," said Rhoda. "People don't carry guns that way around here. Besides, the only part of a gun that the sun would flash on would be the bayonet; and we don't carry army rifles in this country," and she laughed.
"There it is again!" exclaimed Walter.
"I see it, too," said Nan. "Rhoda, what can it be? Something is surely moving this way on a road."
"That is the old Spanish Trail," said the Rose Ranch girl. "It is the trail I told you about, by which the old Conquistadors of Cortez reached this part of the country. And it is the most direct road into Mexico."
"It must be some kind of caravan coming through there," said Bess dryly.
"You are quite right," Rhoda declared. "A party of horsemen are riding this way. And they are Mexicans."
