None of them knew what lay ahead--what dangers awaited them--or what rewards. But they did not hesitate because the first question asked them had been: "Are you a brave man?"_ CHAPTER I _Opportunity_ From where Dick Barrow sat, hundreds of men were visible, occupying benches in every manner of position. Some stretched at full length, sleeping in the morning sun after a night in the park. Others sat with heads hanging; thinking thoughts of their own. Depression or recession, it meant the same to all of them. Some didn't care, but others tried to find any kind of work that would fill their stomachs with food. For three days Dick hadn't eaten a good meal, and felt almost as low as the derelicts whom he had for companions. He would have enjoyed a smoke, but turned away as two men dove for a cigarette-butt; discarded by a passerby. Anyone who could afford to buy a newspaper was an aristocrat, and Dick watched until he saw one discarded. For three days he had been reading them secondhand, but the only jobs were too far to walk and apply for. His eyes stopped at one item in the column and a puzzled frown slowly puckered his forehead. _Wanted: An Engineer. Young man with love for electrical and mechanical work, who is not afraid of isolation. Have some knowledge of engineering, but general experience more desirable than specialized training. Must be willing to leave country, never to return; for which he will be well remunerated. Have no close family ties, and willing to submit to certain amount of danger. Will be isolated with few members of own race, but will have great opportunity to develop mastery of huge machines. Come prepared to leave for post immediately, without preparation. Every want will be taken care of by employers. This position is for lifetime, without opportunity of turning back after having accepted responsibility. GREAT OPPORTUNITY! Room 36, 18 W. Morgan Ave., City._ * * * * * For a long time Dick Barrow gazed at the ad, mentally comparing his own qualifications for the position--and they _seemed_ to fit! He was not a graduate engineer, being forced to quit school after two years of study. Three years later his father died, then Dick lost the job that had kept them eating regularly. His love of mechanics remained insatiable, and he constantly hoped for work which would allow him to use his knowledge and ability. He had no relations, and the _only_ girl had forgotten him, when he left school. He heard that she married a classmate!
