“We [are] still losing dogs through sickness, due to stomach and intestinal worms.
“Wild, Crean, Macklin, McIlroy, Marston, and Hurley each had charge of a team, and were fully responsible for the exercising, training, and feeding of their own dogs. They called in one of the surgeons when an animal was sick. We were still losing some dogs through worms, and it was unfortunate that the doctors had not the proper remedies. Worm-powders were to have been provided by the expert Canadian dog-driver I had engaged before sailing for the south, and when this man did not join the Expedition the matter was overlooked.”
