One of the oldest, and best, problems in puzzledom is the "Mars" puzzle by owner of puzzle.

Shown here is a map of Mars, circa 1900, showing the canals that were thought to exist at that time. At the junctions of these canals are located 20 pumping stations. For the sake of this puzzle the pumping stations have been labelled with letters. Here is the picture and the puzzle:

enter image description here

If you start at station "T", and make a round-trip tour of all 20 stations, you can spell out a complete English sentence. You must travel along the canals and you can not visit any station more than once.

When the owner of puzzle first published this puzzle, over 50,000 readers wrote in, concerning the solution, that "there is no possible way". See if you can succeed where so many have failed in the past.

    $\begingroup$ Are you sure you linked the correct picture? There are 2 station T's, while the text implies only one, and moreover, there are 14 stations, not 20. $\endgroup$

    $\begingroup$ I don't understand why are you speaking of "all" 20 stations, there is only 14 to me... $\endgroup$

    $\begingroup$ Googling found this image which seems to be the intended one. I'd edit, but not sure if that's in spirit of the site regulations. $\endgroup$

NOTE: This was posted while another, incorrect picture had been linked, which didn't fit the requirements mentioned in the question. As such, I googled for the puzzle, and found the correct picture along with the answer. The correct picture has been edited in the question now. As mentioned in my comment the the original post, I don't feel comfortable taking credit for googling, but on the other hand, I'm convinced I could have found the answer without googling had the picture been linked correctly, and I wouldn't find it justified to simply refrain from answering and let someone else take credit. As such, a community wiki.


The people were all correct... The actual sentence is There is no possible way

Comment from the OP: "the owner of the question who says he was sorry."(sic)
