The description on the reverse continues:
These people were part of Furlong's expedition. Two Ona men were cousins. Man on left was Chalshoat and in the center Puppup. Two women on right, and older and younger one, are the two wives of Puppup. Those on the left are Chalshoat's wives. These two families usually traveled in company, except when guanaco were extremely scarce. The fine guanaco hound in front of Puppup was an inevitable companion. The daisy-like flowers may be noted in the grass which covers a boggy terrain.In addition to the material related to the Fuegian peoples, the collection also contains correspondence, notes, and publications related to the controversy over whether Frederick A. Cook or Robert E. Peary reached the North Pole. As Furlong believed that Cook tried to take credit for the work done by Thomas Bridges in compiling his Yahgan-English dictionary, he was always a strong supporter of Peary's claim.
