The poet uses the simile of a log - which clearly is inanimate.
In the classic poem "Silver" by Walter de la Mare, the moon is represented as a lady out walking in silver slippers that shine upon the countryside, causing everything visible to take on a silver glow.
The poem is presented as an American sonnet (Innovative sonnet), made of seven riming couplets.
The "harvest mouse" alludes to the time of year and the indicated setting of a rural area with fruit trees, a dovecote, and a creek teeming with fish. The atmosphere is calm and subdued; the fish are "motionless" and the dog and doves are napping.
The fish is still and the doves are asleep, but the mouse is moving. The moonbeams appear to be moving like a searchlight in the author's depiction of them.
