i did the ship already and got sent back to the main island. now i'm stuck. i'm not sure where to go to get the clues i need to move on to a new age please help and thanks in advance

There is a big tree, and a rocket ship, etc. Have you dug around in the library for clues? It has been a long time since I played so I don't remember all anymore. Have you been in the observatory next to the library?

I am in the rocket ship and am trying to get the music to match. I have given up and am wondering if there is some way of knowing which tones I am off on. I have been trying to get the rocket ship to go for quite a while and am stuck.
I have been to the library and found the book clue and the volts and think I have done that but I just can't get the music set right. Please help

As long as you have 59 volts on the meters, you should have power. I found that if you count the keys to the note you want than move the slider slowly to the same number and you should have the right note. It's kind of tricky.
