Final answer:
The lake near Gull Cottage from the text 'On the Gull's Road' by Willa Cather is not explicitly named but likely references a lake in the English Lake District, possibly a fictional representation of Ullswater or another unnamed lake created for the story.
Step-by-step explanation:
The question is asking about the name of the lake near Gull Cottage, as mentioned in the excerpt from On the Gull's Road, authored by Willa Cather. However, in the given text, the lake is not explicitly named but it suggests a setting near the Lake District, with mentions of Eusemere and Water Millock, which points to Ullswater or a fictional lake inspired by this area.
Ullswater is known for its natural beauty and is the second largest lake in the English Lake District. Gull Cottage seems to be a fictional location, and thus the lake in question is likely to be either a fictional representation of Ullswater or another unnamed body of water created by the author for the setting of the story.
