Robert Frost uses the literary writing techniques of syntax, repetition of lines, simile, metaphor, onomatopoeia, rhyme scheme and especially personification in his poems. The themes I have found in these select six poems support those methods and techniques. I would not be surprised if I read other examples of Frost's poems I would find the same themes and uses of literary methods in those poems also.
In the poem The Pasture, Frost uses a literary technique to emphasize the line "I shan't be gone long. ---You come too." (pg. 889) by repeating it at the end of the first stanza and as the last line of the poem. He also makes it clear that he wants on line to be specially noticed because he puts it in parenthesis. "(And wait to watch the water clear, I may):" (pg. 889).
In the first line of Mending Wall "Something there that is that doesn't love a wall," (pg. 889) sounds like the words are in the wrong order. Here he uses the literary technique known as syntax. In the line " The gaps I mean," he returns to an idea brought up at the beginning of the poem, after drifting into a different thought altogether, when he refers to the gaps in a couple lines above "And makes gaps even two can pass abreast." In one line he says "And on a day we meet to walk the line" (pg. 889) Frost uses the word "line" as a substitute for "wall" which creates the idea of a finite separation between the two properties, at least in his neighbors eyes, with no room for variation. "And some are loaves and some so nearly balls" (pg. 889) this technique is a metaphor, saying the rocks are like loaves even though they really aren't. At one point Frost uses personification to explain why they would not need the wall. He says "He is all pine and I am apple orchard./ My apple trees will never get across/ And eat the cones under his pines, I tell him." (pg. 889) this is insinuating that Frost's apple trees couldn't walk across to his neighbor's property like cows would, even if the wall was not there.
