The speaker of this short poem wants a break from noise. It begins with something small and ordinary, a morning sandwich, and then turns to a surprisingly large request: "deliver me from discourse." Discourse here seems to mean all the talk, argument and chatter that fills a day. The speaker is tired of it and asks to be rescued, almost like in a prayer.
The second stanza adds a condition: this should last "till the ship be brought / home safe." The old-fashioned wording gives the line a hopeful, anxious feeling, as if someone is waiting for a safe arrival. We can't tell from the poem what the ship stands for, so it's open to interpretation.
The last lines ask for something gentle: to be read "the history of pleasure." After silence and waiting, the speaker wants a quiet, shared kind of enjoyment. The mood is calm, wistful and slightly playful, and the title "Hushed" fits it well.
