An autobiographical narrative and extensive correspondence chronicle the life and work of an economic entomologist, detailing investigations into insect pests, practical remedies and preventive measures, and exchanges with fellow researchers worldwide. Editor's notes arrange letters by correspondent and chronology, and illustrations and insect figures accompany technical discussions. Interleaved personal recollections and biographical chapters supply background, while a candid tone, touches of humor, and careful editorial selection emphasize dedication to scientific accuracy, collaboration, and practical agricultural advice.
