Someone asks a simple question in «Forest»: tell me the secret of springtime. The speaker spends the whole poem circling that question and never answering it. Jack Spicer builds a love poem out of refusal, and the refusal turns out to be the most intimate thing in it.
The central move comes in the second stanza, where the speaker compares his relation to the secret to "a high-branching firtree / Whose thousand little fingers / Point a thousand little roads." The image works in two directions at once. A tree with many branches suggests abundance, a thousand possible things to say. But fingers that point down a thousand roads also suggest scattering, as if the secret, once spoken, would dissolve into too many directions to follow. The speaker is not hiding a single fact. He is carrying something too many-sided to hand over in a sentence, and the tree becomes a picture of that fullness.
His reason for refusing is oddly gentle: "I will tell you never, my love, / Because the river runs slowly." The logic does not quite connect, and that seems deliberate. A slow river offers no real explanation for silence; it works more like a mood, a sense that things in this poem move at their own unhurried pace and cannot be rushed into disclosure. What the speaker offers instead is a substitute: "I shall put into my branching voice / The ashy sky of your gaze." Here the tree and the speaker merge. His voice has branches, and what it carries is the beloved's own look, grey and soft, reflected back. He cannot give the secret, but he can give back the way he sees the other person, and the poem implies that this may be the closest thing to the secret available.
The tone shifts in the middle, becoming playful and physical. "Turn me around, brown child / Be careful of my needles" casts the beloved as someone handling the tree, perhaps spinning it like a Christmas fir, and the warning about needles keeps tenderness and prickliness together. Love here is something you can be scratched by. The phrase "playing / At the well pump of love" extends the game: a pump is something you work by hand, drawing up what lies underground, and the image quietly echoes the whole poem's problem. The beloved keeps pumping, and the speaker keeps being unable to produce the water on demand. The line break after "playing" lets the word hang, so that play and love and effort briefly occupy the same space.
The form is lean and unrhymed, built from short two-line stanzas that move almost like breaths. The lines are loosely paced, closer to speech than to strict metre, and the plain vocabulary (river, sky, needles, pump) keeps the poem from sounding grand. The repetition of "a thousand" and of "turn me around" gives it a faint incantatory rhythm, almost a nursery-rhyme lilt, which suits the childlike address of "brown child" while the content stays quite grown-up.
The ending returns to the opening almost word for word: "The secret of springtime. How / I wish I could tell you!" The sentence now sounds different. At the start it was a request; here it is a confession. The exclamation mark releases the pressure the poem has been holding, and the wish carries real longing rather than coyness. The speaker is not withholding out of stubbornness. He seems to lack the means of telling, as though the secret exists only in the doing: in the turning, the needles, the branching voice.
What makes the poem worth reading is how much it does with so little. It treats the failure of language between lovers not as a tragedy but as part of the game, something that can be played with, even enjoyed. The secret stays unspoken, yet the poem itself, with its tree and its pump and its ashy sky, is the nearest the speaker can come to saying it.
