Dr.Tisco bowed low before the charming girl.

Tom and Harry were presented, and tried to make themselves agreeable to the young Mexican girl.
Senorita Francesca's shyness, however, made this somewhat difficult, so the young engineers felt inwardly grateful when Dr.Tisco strolled down the porch with her.
Dinner proved to be a somewhat formal affair.

Yet, as soon as the meal was finished Senorita Francesca was escorted from the dining room by her father and returned to her room.
"What did you think of the young lady, Tom ?" Harry asked his chum when he could do so privately.
"A fine-looking girl," Reade answered briefly.

"But I fear she would be highly offended if she knew that, all through dinner, my every thought was on the mine and the problems that we shall find there." "I want to talk with you about that mine, and about some impressions that I have formed here," murmured Hazelton.
"Then another time, my dear fellow, for here comes Don Luis, and I see Dr.Tisco returning from the garden." That forestalled conversation for the time being.

When the young engineers, still relentlessly attended by Nicolas, sought their own rooms Hazelton was so drowsy that he undressed hurriedly and dropped into bed.
