July 19, 1919: "On June 29, Oscar Hayward of Burnt Ranch, California, assisted by several neighbors, cut and smudged a bee tree in the vicinity of Burnt Ranch. They left the smudge, unextinguished, and the fire spread over an acre of government and private land. The fire was discovered and reported by F.B. Hoffman, Ironsides lookout, to Ranger Brannan. J.D.McDonald and E.N. Leach succeeded in putting the fire out, completely, after five hours work. On July 11, Special Investigator Leventon appeared on the scene, and with the assistance of Ranger Brannan, secured the evidence which led to the arrest and conviction of Oscar Hayward. As the instigator of the smudging episode. Hayward agreed to go to Weaverville, plead guilty and pay the fine. This he did on July 14, and it is to be hoped that his accomplices will be good sports and help bear the burden of the $50 fine which was imposed. Pretty expensive honey!" (Red Bluff Daily News)
September 8, 1921: "According to correspondence in this office, Lookout Frank B. Hoffman, of Ironsides, has made quite a hit in some San Francisco schools -- notably, Hawthorne and Bryant schools - by sending them properly labeled specimens of various trees for observation and study. Judging from the letters he has received, some of these had never been seen by children and a great deal of interest seems to have been manifested. This is surprising, as one would naturally suppose that San Francisco children would have access to Golden Gate Park and would be familiar with most ordinary trees. The interest shown makes me wonder whether this lack of knowledge is common in other schools, and whether it might be worth while to route a series of collections to the various schools in that city." (California District News Letter)
