These materials include a complaint from local Carlisle businessman John H. Lau against Charles H. Carns, the painter at the Carlisle Indian School. Lau, of the local carriage-maker E. A. Lau and Sons, claimed that Carns was inappropriately undercutting his carriage-painting costs. After investigation, Second Assistant Commissioner of Indian Affairs C. F. Hauke determined that Carns working odd jobs in town was not counterproductive to his work at the Indian School nor to Lau's business.
