The Indian Office advised Campbell that the Park Saddle Horse Company, one of James J. Hills Great Northern Railroad subsidiaries was trespassing on western reservation lands adjacent to Glacier Park and was competing for grazing leases with the Indian stock owners. J.W. Schultz, author of Indian tales, and former reservation prospector, now lived in Los Angeles and Arizona on Blackfeet oral history sold to magazines of western history; stories told him by Blackfeet warriors of their war exploits. He now tried to sound the alarm of starving Blackfeet Indians under Campbell’s Five Year Program: “The Indian Bureau is all powerful; Congress will pass any bill that it recommends. But it will not admit its failure with the Blackfeet and ask for an appropriation to give them the relief they sorely need. Therefore, others must provide it.”

In 1920 Campbell advised the Indian Office that prospects for farming looked poor and admitted that many of the white farmers were not renewing their leases. He indicated it was impossible to explain to the full bloods that they must pay an annual sum to defray the construction charges for their irrigable allotments [which the Indians did not want] and as many were unable to pay, it became more difficult to lease the irrigated lands to whites, who would not pay either.
