Jane Taylor is best remembered for "Twinkle, Twinkle, Little Star", and "The Apple-Tree" shows the same gift for plain, singable verse, here put to a sterner purpose. A boy named Dick, standing in the heat, eyes the ripe fruit on his neighbour's tree and talks himself into taking one. Just as his hand reaches the branch, a voice stops him with a reminder that God sees and hears everything, even in the dark. The central idea is that being unobserved does not make a wrong act harmless. Dick's whole argument rests on not being caught, and the poem exists to take that argument apart.
The form helps it do so. Each of the five stanzas has six lines rhymed aabccb, with two long lines paired, a shorter line, two more long lines paired, and a shorter line that rhymes with the first short one. The lines mostly gallop in threes, as in "Old John had an apple-tree, healthy and green", then shorten to three beats for "So juicy, so mellow, and red." This bouncing, nursery-rhyme movement is easy to memorise, but it also gives the poem a calm, tidy surface, so that the warnings in the last two stanzas arrive in the same cheerful rhythm as the description of the apples. Contractions such as "pass'd" and "look'd" keep the beat steady.
The opening stanza is more carefully built than it first seems. The tree is "healthy and green", the codlins "juicy", "mellow", and "red", and these sensory words make the fruit tempting to the reader as well as to Dick. Then comes the detail that matters most: Old John sells his apples "to buy him a morsel of bread." The tree is his livelihood, so the theft would be taken from a man with very little. Dick never thinks about this, and the poem never says it outright. But when the last stanza declares "'Twere better to starve than to steal," the word echoes John's "morsel of bread". Dick is only hot and wants something "cool and refreshing", so his reasons are weak beside John's need.
The poem charts the temptation step by step. Dick begins with a "longing eye" and a wish, moves on to "thinking whether he might not take one", and then looks "over the wall", a small physical line he is already crossing in his mind. Next he speaks, and his self-justification is neatly sly: "one only I'll take", "John cannot see", "nobody is in the way." Each excuse shrinks the offence, and none claims the apple is his. The quotation marks that open in stanza three are never closed, so the voice that interrupts, "But stop, little boy, take your hand from the bough", seems to grow out of Dick's own thoughts. It could be the narrator or his conscience. By now his hand is already on the tree, and the temptation has travelled from eye to mind to fingers.
The reply is aimed exactly at his excuses. Dick has counted on John not seeing and on no one being near, and the voice answers that "There is One" who "can see all you do, and can hear all you say", covering both sight and speech. In the final stanza God is a kind of bookkeeper who "Writes down every crime we commit, in His book." The word "crime" is large for an apple, and the poem is aware of this, since the scale is part of its lesson that small dishonesties count. The last line also shifts from "you" to "we", which widens the warning from one boy to the reader. The poem then stops without telling us whether Dick walks away, leaving the reader in his place with the apple still hanging there.
What makes the poem worth studying is how openly it is built to teach. It is a clear example of verse meant to shape a child's conscience, and it does so through fear of being watched rather than sympathy for John, which may feel heavy-handed to modern readers. Even so, its psychology is convincing. It understands how temptation grows by small steps, and how a child can build a case for doing wrong out of reasons that sound sensible.
