A mile across the valley the Lutheran Seminary is seen, the most conspicuous landmark of the Confederate line. To the southeast from the cemetery is Culp's Hill, strewn with rocks and boulders and covered with trees. The Emmettsburg road goes southward down the valley, gradually diverging from the Union line, and crossing the fields that were the battleground on the second and third days. It is bordered by numerous monuments, some of great merit, and leads to the "Peach Orchard," where the line bends sharply back. Peach trees are replanted here as the old ones fall. The "Wheat Field" is alongside, now grass-grown. Beyond it the surface goes down among the crags and broken stones of the "Devil's Den," a ravine through which flows a stream, coming from the orchard and wheat field, and separating them from the rocky "Round Tops," the sandstone cliffs of the "Little Round Top" rising high above the ravine. The fields sloping to the stream above the Den are known as the "Valley of Death." Among these rocks there are many monuments, made of the boulders that are so numerous. A toilsome path mounts the "Big Round Top" beyond, and an Observatory on the summit gives a good view over almost the entire battlefield. This summit, more than three miles south of Gettysburg, has tall timber, preserved as it was in the battle. There are cannon surmounting the "Round Tops," representing the batteries in action. Across the valley to the west is the long fringe of timber that masked the Confederate position on Seminary Ridge. A picnic-ground, with access by railway, is located alongside the "Round Tops." The lines of breastworks are maintained, and upon the lower ground, not far away, are preserved the rough stone walls, and to the northward is the little umbrella-shaped grove of trees at which Pickett's charge was directed. The Twentieth Massachusetts regiment brought here a huge conglomerate boulder from New England and set it up as their monument, their Colonel, Paul Revere, being killed in the battle.
