Answer:
The poem appears to be describing the beauty and vastness of the Gatineau Hills in Quebec, Canada. It tells the reader to look out from the top of the hills and take in the entire expanse of glittering green in one wide sweep. The poem then encourages the reader to take a closer look, to pick a leaf from the ivy and trace the fine veins. It suggests that by focusing on one small thing, the reader can see the whole wide valley in a green beam. The poem is a reminder that sometimes it is the small details that make the big picture more beautiful and meaningful. The imagery of river, fields, roads, and limestone bed give the sense of natural beauty and peacefulness. The poem encourages the reader to take a moment to appreciate the beauty of nature.
