An avid gardener, Langohr began selling lettuce he grew in hot beds next to his house and expanded his business by building a greenhouse. He retired from his Forest Service job to run the nursery business full time in April, 1906. Michael Langohr died in Bozeman, Montana in 1935, but the business he founded continues in operation to the present. The Michael Langohr diary is a typed transcript of entries which describe his daily activities as the first supervisor of the Gallatin National Forest in southwest Montana. Information includes synopsis of visitation to check on grazing and timber lessees, weather conditions, and travel distances.
Entries are typically very succinct.
Final pages record applications of varying sorts such as grazing and timber leases.
