b&w photograph Excellent condition. A male student, who seems to be sitting at a picnic table, leans over a pan of water and vegetation, picking up samples with an eyedropper. Petri dishes and lined paper are also in front of him on the table. The student is on a two-week biology field trip to Vinegar Lake in Hubbards, Nova Scotia. From External Affairs. On the reverse, 'Vinegar Lake filed trip Aug 28/95' is written at the top in red ink and '272.1' is written in pencil directly under it. A Post-It note stuck to the back has 'Biology' written on it in black pen.
