Question

Which line from the poem best illustrates alliteration?

“From their shadowy cote the white breasts peep”
“Walks the night in her silver shoon;”
“A harvest mouse goes scampering by,"
“By silver reeds in a silver stream,”

Answer 1

"By Silver reeds in a silver stream". There is an emphasis on the repeated S sound in the sentence. 

Answer 2

"By Silver reeds in a silver stream"

Step-by-step explanation:

Alliteration is derived from Latin's "Latira". It signifies "letters of the alphabet". It is a complex device in which various words, having a similar first consonant sound, occur near one another in an arrangement.

In this case there is an emphasis on the repeated S sound in the sentence By Silver reeds in a silver stream.
