An adventurer (named Moses, for humor's sake) finds a clear pool of water deep in a cave. Upon taking a swim, he finds at the bottom of the pool is a mystical stone that eternally puts out water, seemingly from nowhere. Hailing from the desert, he realizes what an amazing find this is!
Moses tries to think of a good way to transport the stone out of the cave, across many leagues of rough terrain, and deposit it where he can safely monetize its output in his desert city.
The stone artifact is heavy and largish, let's say a cube of about a meter's size (but it doesn't matter too much). This would make it weigh something like 2500 kg.
The stone is located about a meter below the surface of the pool of water. You could easily stand on top of it and still have your head above the surface.
It puts out water slowly, like a small mountain spring. Unfortunately, this ability can't be turned off, so it can make travel very, very wet.
The world has a limited technology level (Renaissance era-ish) and, more importantly, the character has a limited budget!
Bonus points if you give special attention to how the properties of the artifact affect (for better or for worse) your proposed travel technique.
