A puppy rescued from the Milwaukee River by crew of the lighthouse tender Hyacinth in 1914 became more than a mascot: He was a friend to the men on the boat. Named Sport, the dog spent 12 years attached to the Hyacinth as it traveled up and down Lake Michigan, marking channels and bringing supplies to lighthouses. Sport became well known at every port and lighthouse on the Hyacinth’s route, sometimes playing with lighthouse keepers’ children, sometimes exploring on his own. Sport was so well known that when he was mistaken for a stray after wandering too far, a crew member from another ship recognized him and helped him hitch a ride on another boat back to the Hyacinth. This captivating account is fictionalized, but based on fact. More about the real Sport follows the story. (Ages 5–8)
