There really is a notebook for everything…
“For close to 60 years, a set of notebooks sat unused in the herbarium at the Yangambi Biological Station in the Democratic Republic of the Congo. During the colonial era, this was an agricultural research station, the National Institute for Agronomic Study of the Belgian Congo, or INEAC. Every week for two decades, from 1937 to 1958, biologists at the station observed 2,000 individual trees and recorded whether they had flowered, fruited, or dropped their leaves. As The Guardian reports, the scientists scrawled their observations in small notebooks and coded them into larger logs, creating a detailed record of forest life during the final decades of Belgian occupation of this part of Africa.”
