What is tarry scant?

"Tarry scant" is a phrase that appeared in a poem by Forrest Fenn, which he wrote in connection with a treasure hunt he initiated in the Rocky Mountains of the United States. The poem contains clues to the location of a hidden chest that contains over a million dollars worth of gold and other valuable objects that Fenn claims he buried somewhere in the mountains. The phrase "tarry scant" has been interpreted by many to mean that the person searching for the treasure should not waste time or hesitate, but instead quickly move on to the next clue or location. There is much speculation and debate among treasure hunters as to what precisely the phrase means and how it relates to the rest of the poem's clues.
