What role did the foulis brothers play in the development of the golf ball?

The Foulis brothers took the 'Haskell ball' and remolded the outer shell with a bramble marking or pattern. The Haskell ball would tend to 'duck' because of it's outer surface.

"and even Jim couldn t keep them from ducking to the ground just off the

tee. "

It was at that point they remolded the ball with the bramble pattern, the same as the gutta percha ball.

"The brothers made quite a bit of money improving the Haskell and making

the ball fly further. Besides reselling the Haskell, they also manufactured their own golf balls, calling them the American Eagle "
