Oburn & Montgomery

                                                               Cattlemen.
The earliest item relative to “Oburn” appeared in a Caldwell newspaper that I copies items from. It shows that he had a partner (Montgomery). I do not know if this was the same person that Diane is looking for. You will note that many of the items were repeated in other newspapers, a common practice in those days. It appears that the main source was the Cheyenne Transporter. MAW

Thomas Lemons, for the past year in the employ of Oburn & Montgomery, and who since relinquished his position with that firm and went north with a herd of ponies, returned last week as happy and jovial as ever. He disposed of his ponies at Arkansas City at good advantage.

The range boys have been enduring a severe time during the recent cold snap—some freezing their fingers, ears, and nose. That’s pretty tough on ’em.
The river at this point has been closed for the past two weeks, and today the Agency people commenced laying by a second supply of ice, which is about six inches thick.

Frass reports four head died at his camp.
