This is a vintage woodcut-style illustration depicting a double-arched aurora borealis over a landscape. The aurora is the dominant feature, appearing as a bright, arched band across the sky with numerous vertical streamers extending downwards. The aurora is rendered with dense, fine lines, creating a luminous effect. Below the aurora, a dense forest of coniferous trees stretches across the width of the image. The trees are depicted with detailed foliage and varying heights, creating a sense of depth. A small stream or river meanders through the forest, reflecting the light from the aurora. Rocks and boulders are scattered along the banks of the stream, adding to the ruggedness of the landscape. The sky above the aurora is dark, providing a stark contrast to the bright lights. The overall style of the illustration is reminiscent of 19th-century scientific illustrations, with a focus on detail and accuracy. The image is labeled 'Fig. 233. - DOUBLE-ARCHED AURORA WITH STREAMERS.'
