Once there was a golfer whose drive landed on an anthill. Rather than move the ball, he decided to hit it where it lay. He gave a mighty swing. Clouds of dirt and sand and ants exploded from the spot. Everything but the golfball. It sat in the same spot.
So he lined up and tried another shot. Clouds of dirt and sand and ants went flying again. The golf ball didn't even wiggle.
Two ants survived. One dazed ant said to the other, "Whoa! What are we going to do?"
Said the other ant: "I don't know about you, but I'm going to get on the ball."

Black American patent

In 1897, a U.S. patent for an improvement in "Casting Composite or Other Wheels" was issued to black American inventor E.R. Robinson (No. 594,286). It gave a method for casting wheels wherein the outer sides are of one metal and the interior portions are of another metal. The importance was not only to enable casting a metal of high electrical conductivity, such as brass, in a groove of an iron trolley wheel - but also to permit an entirely new contruction consisting of two outer disks or flanges and an intermediate, uniting portion, which extends from the contact portion of the wheel with a web extending to the centre and an integral bushing. Robinson also held a previous patent, issued four years earlier, for an "electric railway trolley."[Image: plan view of bottom section of a wheel three-part mold]
