There is a legend of lead balls down in the hill country, the story goes something like this:
Back about 1910 a man in a wagon, pulled by a pair of swayback horses, rode up to a farmhouse in the hill country of Texas. A widow and her grown son lived there. In the yard was a lead ball and the stranger asked about where it came from and if they would be interested in selling it. The woman explained that one of her boys had plowed up in the field years ago. The stranger offered twenty-five dollars for the lead ball, back in those days that was a pile of money. The stranger paid her and then asked for use of their axe from the wood pile. The stranger put the ball in the crook of a piece of fire wood so it would not roll and then went to wailing on the lead ball.
When he cut the ball in two it was full of gold nuggets. The stranger gave half of the nuggets to the widow and her son. It's reported that the nuggets were valued at $7000 (1910 dollars). The stranger told them that there were four lead balls, and the gold in them came from one of the San Saba mines and that the Spaniards had left them. The four balls formed the corners of an exact square four hundred yards to the side. An attempt was made to find the other three balls, but the spot where the one ball had been found had long since been forgotten, so none one of the four corners could be established. The widow and her son could only remember that the ball had been plowed up along one of several washes that ran along one of the edge of their field.
That's what remember of the legend, and when you think about it, the legend doesn't make sense. Why would you mark the corners of a field with lead balls filled with gold? Also the Spaniards didn't use a distance of the yard, it was a vara (about 33 inches).
