Translation of Glockenblume

Clara agreed about a month ago to give me her acquaintances' contact details from NYU and Columbia. I have just spoken to her now and she told me that you could help me and send me those files.
Let me continue to tell you about my adventures. So, as I have told you in my last writing I returned to the airport and scheduled a new date for my flight. This time I left myself five more days.
My wife joined me two hours later and everybody went to breakfast. The plan for the day was to visit a cave on one of the islands. We took smaller boats to get there as the ship was too large to approach the island.
