Step-by-step explanation:
Henry's experiences working on the Panama Canal that eventually led him to run away were characterized by unfair treatment and discontentment. Henry worked for a master who demanded the full amount of his wages and gave him only a small portion as encouragement. This made Henry feel like he deserved the whole amount and fueled his desire to escape.
Additionally, when Henry tried to hire his time to earn money for his escape, his request was denied by his master. His master advised him to be content with his situation, discouraging any plans for the future. However, Henry persisted in his thoughts of escape and the injustice of enslavement.
