Right: Old Trusty Incubator made by the M. M. Johnson Company of Clay Center. Nationally successful, the company produced more than 100,000 incubators and chick brooders in 1910 alone. In 1925 Johnson started radio station KMMJ in Clay Center as a service to farmers and as a way to sell more incubators. This incubator was used on the Hesson farm near Unadilla.
