How a journey is found
Every specimen with a full date and a known collector is a diary entry. The days are read in order; a gap of more than three weeks ends one journey and starts the next. Days spent where a collector lived most of their life are home, not travel, and are left out.
A journey needs at least five days, forty specimens and two places. Within it, a run of days spent within about ten kilometres is one stop; the stop’s point is the middle of the labels that carry coordinates, or the island’s centre when none do.
Companions are the people whose own labels put them in the same place on the same days. Staff can name a journey, write about it and feature it; everything else here is read straight off the specimens, and is rebuilt as the records improve.
