Walkthrough. Note, this is a walkthrough for an early, non-graphical version of the game. Most of it should still be valid for later versions, but some of the problems dealt with in this walkthrough (such as the precaution of not leaving the pump in the boat) are not a problem in later versions. Conversely, later versions require some additional actions such as picking up the message and reading a sign. Second note, older versions of the game do not allow common abbreviations such as N, U, and I, you will need to type GO NORTH, GO UP, TAKE INVENTORY, etc. though you should be able to get away with using just the first four letters of each word.
