Final answer:
The provided excerpts do not mention what Watson saw after hearing the hound baying. Different scenes describe characters' experiences with elements of suspense, danger, and emotional relief.
Step-by-step explanation:
After hearing the hound baying, Watson did not immediately see anything according to the extracts provided.
The passages shared do not specify an observation made by Watson following the sound of a hound.
Instead, various other scenes from different contexts are described.
We learn about characters such as Jane Withersteen, Lassiter, and Venters in different situations involving emotional encounters, tension, and danger.
For instance, Jane hears a low rumbling roar which Venters also notices, but no character named Watson is mentioned in relation to hearing a hound.
