In 1871, Fred Peppin said, "We were satisfied with the type of wool that the country would grow, instead of endeavoring to produce what the climate and soil continually fight against.
Thus we developed all its good natural tendencies and after the flock had a character of its own, tried experiments on a small scale only, and in such a way that they could do no permanent injury, and abandoned then when they were found not to achieve the desired object.
In 1874, the Peppin brothers, George and Frederick, formed a double stud (recorded ewe and ram pedigree), the foundation stock being selected by T. F. Cumming.
North Boonoke station with 26,788 sheep, 290 cattle, 63 horses and 31,484 acres (127.41 km²) of freehold land was sold for £67,000 to F. S. Falkiner, Malcolm McKenzie and J. R. Ross in November 1878.
When Franc Falkiner died in 1909, he had amassed in excess of 500,000 acres (2,000 km²) of Riverina grazing land and was running a quarter of a million Boonoke blood sheep.
