This chapter studies how the mission changed as years went by, especially after they had to look for new sources of funding. It also gives a new perspective on what the Great War meant for science, and how Chilean society was changing, mainly through its urban history-that also affected the observatory, since the place they chose was transformed into a public park. This chapter also describes plans for finishing the mission and the departure of the Lick's team. The Americans decided to sell the Observatory to Chile's Catholic University, and then again cultural differences challenged the negotiations. The astronomers left the country with great sorrow, after living and working in that far away country.
