History of Westchester County, New York, Vol. II
Along the line of the Union Pacific, between the towns of Lewellen and Keystone, there is a sand hill ridge that runs down from its associates almost to the railroad track.
This section up which it is situated contains just about enough level ground for the location of a house and ranch buildings, and the buildings are there.
This was once the humble home of Perry Yeast, who now lives in his palatial home in Lincoln, and is worth a million or so.
When Perry settled there, it was ranches all around him. the Ogallala Company and John Bratt & Company in particular. Perry was an adept at the work of discovering unbranded stock on the range. He built him a rack, or pen on wheels, with which he used to roam about the country, and unidentified stock of the range would soon wear his brand. He simply took to himself the same rights that the cattle associations assumed they possessed. The Ogallala people thought it might be best to keep him occupied in other pursuits, and gave him a contract for putting up the hay on their North river meadows one year. He cleared up several thousand dollars in the deal.
When the Burlington built through the Sand Hills he contracted to furnish meat for the construction gangs and he did furnish it in such quantity that Bratt & Company thought he could not be supplying it entirely from his own herd. An investigation and search of the Sand Hills disclosed a secluded spot with the fragments of about a hundred hides, all of which were once worn by Bratt cattle.
