Final answer:
The second floor of the sheriff's residence in the play 'Trifles' by Susan Glaspell is not detailed in the text; its symbolic meaning is inferred from dialogue and the setting of the main floor.
Step-by-step explanation:
The question appears to inquire about a specific location within a fictional setting, the Old Minnehaha County Jail. Based on the provided references, which include excerpts from Susan Glaspell's play Trifles and imagery of historical architecture, one can deduce that the second floor of the sheriff's residence is not explicitly detailed within the text.
Instead, the question might refer to the play's use of physical spaces to symbolize the characters' relationships and social roles. In the play, the characters enter the domicile of John Wright to investigate his murder. The kitchen and its disorder serve as an extension of the life of Mrs. Wright, reflecting her mental state and possibly her motives. The second floor, which they intend to investigate next, would similarly offer insights into the private life and tensions within the household.
However, the actual minutiae of what is delineated by the second floor are not provided in the text. This allows the audience to infer certain aspects of the Wrights' private lives from the dialogue and actions occurring on the main floor and from the emotional reactions of the characters involved.
