Four short lines are enough for Nathaniel S. Rounds to build a whole food chain. "Snakes / eat the rats / that eat the ties / on the track." The verb "eat" appears twice, and the sentence passes from creature to creature like a riddle or a nursery rhyme. The surprise is at the bottom of the chain. Ties are the beams that hold a railway together, made by people to last, and here they are a meal. Before any human appears, the poem has shown a railway being slowly consumed. The plural endings of "snakes," "rats" and "ties" also give the stanza a faint hiss, which suits its subject.
Then the people arrive, and the tone changes. "Seven nights ago / some boys from town / stole the crossing gate." The speaker sounds like someone passing on local news. The time is counted, the boys are vague ("some boys"), and nobody is named or blamed. The verb "stole" is harder and more legal than the soft, animal "eat." Yet a crossing gate exists to stop people walking into the path of a train, so stealing it is a small crime with a large symbolic weight. The title adds to this. A crossing point is literally where road meets rail, but it can also be read as the moment when something stops being used and starts being scavenged.
The last stanza explains the theft. "It was there for the taking." The word "taking" echoes "eat," and the echo is the poem's quiet argument. The boys become one more link in the chain, after the snakes, the rats and the ties. Nature and teenagers do the same thing: they consume what has been left unguarded. The poem never calls this wrong, and the phrase "for the taking" nearly excuses it.
The form supports that reading. The poem is in free verse with no rhyme. The first two stanzas use very short lines of about three to five syllables, so it moves in small, even steps, like someone walking the track and counting. In the final stanza that pattern gives way. One long line, "It was there for the taking. For the line lies forgotten," runs on well past anything before it and then spills into a short last line. The speaker seems to stop reporting and start justifying. The word "For" at the start of the second sentence works like "because," so the ending sounds like a verdict.
The final line is full of small effects. "Line lies" repeats its l and long i sounds, and the words seem to settle into stillness as they describe it. "Lies" might also suggest untruth, as if the line has been left with a false promise that trains will return. That is only a possible reading, and the poem never says so. "Forgotten" is a passive word, and it is more chilling for that. We are not told who forgot, only that no one remembers. The poem then ends on "gone," the plainest word available, with nothing after it. We can't tell whether the freight train has gone for the night or for good, but "lies forgotten" points to the second.
The poem is also significant for what it leaves out. It gives no history of the railway, no reason for its closing, and no judgment of the boys. Judging by the imagery, it is set in a small town with a dead line running past it, but the poem doesn't tell us more, and it doesn't need to. Its power comes from order. By putting the snakes before the boys, Rounds makes human theft look like part of a natural process, as ordinary as a rat chewing wood. The idea behind it is a hard one: when something is no longer needed, it is not simply left alone. It is eaten, taken or carried off, and the poem treats that as how the world works.
