At a glance Costal saw what the strange object was--a broad band of gold lace encircling a _sombrero_, and placed, Mexican fashion, around the under edge of the brim. The cigar illuminating the lace had deceived the negro, guiding him to the idea of a diadem! "_Carajo_!" muttered Costal between his teeth, "I told you so. Did I not say that some profane white had hindered the Siren from appearing?" "You were right," replied Clara, ashamed at the mistake he had made, and from that time losing all belief in the _genius_ of the cascade. "An officer!" murmured Costal, recognising the military equipments of the dragoon, who, with a carbine in one hand, and his bridle in the other, sat smoking his cigar, as immoveable as a statue. "Who goes there?" cried Costal, saluting him in a loud, bold voice. "Say, rather, who stands there?" responded Don Rafael, with equal firmness, at the same moment that he recognised in the speaker the Indian whose incantation he had witnessed. "Delighted to hear you speak at last, my fine fellows," continued the dragoon in his military off-hand way, at the same time causing his horse to step forward face to face with the adventurers. "Perhaps we are not so much pleased to hear you," replied Costal roughly, as he spoke, shifting his gun from one shoulder to the other. "Ah! I am sorry for that," rejoined the dragoon, smiling frankly through his thick moustache, "for I'm not inclined to solitary habits, and I'm tired of being here alone." As Don Rafael said this, he placed his carbine back into its sling, and rebuckled the straps around it, as if it was no longer required. This he did notwithstanding the half-hostile attitude of the adventurers. The act did not escape the quick perception of the Indian; and, along with the good-humour manifest in the stranger's speech, made an instantaneous impression upon him. "Perhaps," added Don Rafael, plunging his hand into the pocket of his _jaqueta_, "you have no good feeling towards me for disturbing you in your proceedings, which I confess I did not understand. Neither did they concern me; but you will excuse a strayed traveller, who wished to inquire his way; and as I had no means of making myself heard to you, I was forced to adopt the method I did to draw your attention. I hope that on reflection you will do justice to my dexterity in taking care that none of the stones should hit you." As he finished speaking the dragoon took a dollar from his purse, and offered it to the Indian. "Thank you," said Costal, delicately refusing the piece, but which Clara, less scrupulous, transferred to his pocket. "Thank you, _cavallero_! May I ask where you are going?" "To the hacienda Las Palmas." "Las Palmas?" "Yes--am I far from it?" "Well," replied Costal, "that depends on the road you take." "I wish to take the shortest. I am rather pressed for time."
