"Gallant attack by 150 of the Pennsylvania Bucktails, led by Colonel Kane, upon a portion of General Stonewall Jackson's Confederate Army, stronly posted in the woods, near Harrisonburg, Friday, June 6th, 1862. We illustrate one of the most heroic actions of the war, the attack of the famous Bucktails, under their gallant leader, Colonel Krane, upon a large portion of Stonewall Jackson's army, consisting of infantry, cavalry and artillery. The spot where this deadly conflict took place was about a mile and a half beyond Harrisonburg, on the road to Port Republic, toward which place the Confederates were in full retreat, closely but warily pursued by Generals Fremont and Shields. On Friday, June 6th, Colonel Sir Percy Wyndham, of the First New Jersey Cavalry, having been sent by General Bayard to reconnoitre, was led into an ambuscade, where his regiment was fearfully cut up, and himself wounded and taken prisoner. It will be seen that the humanity of Colonel Krane led him into a similar trap. News of what had occurred was rapidly transmitted to headquarters, and General Bayard was ordered out with fresh cavalry and a battalion of Pennsylvania Bucktails. But the Sixtieth Ohio had already beaten back the bold Confederates. The evening was waxing late; General Fremont did not wish to bring on a general engagement at this hour, and the troops were ordered back. "But do not leave poor Wyndham on the field, and all the wounded," remonstrated brave Colonel Krane of the Bucktails. "Let me at 'em, general, with my Bucktails." "Just forty minutes I'll give you, colonel," said General Bayard, pulling out his watch. "Peep through the woods on our left, see what is in there, and out again when the time is up." In go the 150 at an opening in the pines; they were soon surrounded by a cordon of fire flashing from the muzzles of more than a thousand muskets; but not a sign, nor the shadow of a sign, of yielding. Their fire met the enemy's straight and unyielding as the blade of a matador. Oh for re-enforcements! But none came. The brave Bucktails were forcd to retreat across the fields of waving green, firing as they did so- but not the 150 that went in. The rest lie under the arching dome of the treacherous forest." — Frank Leslie, 1896

"View at the Spring; Hobkirk's Hill. It is at the hed of a ravine, scooped out of the northeastern slope of Hobkirk's Hill. The noble trees which shadow it are tulips, poplars, and pines. The house seen on the top of the hill, toward the left, is the residence of William E. Johnson, Esq., president of the Camden Bank. A few yards below the spring a dike has been cast up, across the ravine, by which a fine duck pond is formed, and adds beauty to the scene, in summer."—Lossing, 1851

"The position of the true meridian may be found as follows: Point the hour hand of a watch towards the sun; the line joining the pivot and the point midway between the hour hand and XIII on the dial will point towards the south; that is to say if the observer stands so as to face the sun and the XII on the dial, he will be looking south. To point the hour hand exactly at the sun, stick a pin and bring the hour hand into the shadow. At night a line drawn toward the north star from the observer's position is approximately a true meridian." — Moss, 1914

"When the Moon falls into the shadow of the Earth, the rays of the Sun are intercepted, or hid from her, and she then becomes eclipsed. when the Earth's shadow covers a part of her face, as seen by us, she suffers only a partial eclipse, one part of her disc being obscured, while the other part reflects the Sun's light. But when her whole surface is obscured by the Earth's shadow, she then suffers a total eclipse, and of a duration proportionate to the distance she passes through the Earth's shadow." —Comstock, 1850

"When the moon psses between the Earth and Sun, there happens an eclipse of the Sun, because then the Moon's shadow falls upon the Earth. A total eclipse of the Sun happens often, but when it occurs, the total obscurity is confined to a small part of the Earth; since the dark portion of the Moon's shadow never exceeds 200 miles in diameter on the Earth. But the Moon's partial shadow, or penumbra, may cover a space on the Earth of more than 4,000 miles in diameter, within all which space the Sun will be more or less eclipsed. When the penumbra first touches the Earth, the eclipse begins at that place, and ends when the penumbra leaves it. But the eclipse will be total only where the dark shadow of the Moon touches the earth." —Comstock, 1850

A sundial is a device that measures time by the position of the Sun. In common designs such as the horizontal sundial, the sun casts a shadow from its style (a thin rod or a sharp, straight edge) onto a flat surface marked with lines indicating the hours of the day. As the sun moves across the sky, the shadow-edge progressively aligns with different hour-lines on the plate. Such designs rely on the style being aligned with the axis of the Earth's rotation. Hence, if such a sundial is to tell the correct time, the style must point towards true North (not the north or south magnetic pole) and the style's angle with horizontal must equal the sundial's geographical latitude.

In the common vertical dial, the shadow-receiving plane is aligned vertically; as usual, the gnomon's style is aligned with the Earth's axis of rotation. As in the horizontal dial, the line of shadow does not move uniformly on the face; the sundial is not equiangular.

In the common vertical dial, the shadow-receiving plane is aligned vertically; as usual, the gnomon's…

In polar dials, the shadow-receiving plane is aligned parallel to the gnomon-style. Thus, the shadow slides sideways over the surface, moving perpendicularly to itself as the sun rotates about the style. As with the gnomon, the hour-lines are all aligned with the Earth's rotational axis. When the sun's rays are nearly parallel to the plane, the shadow moves very quickly and the hour lines are spaced far apart. The direct East- and West-facing dials are examples of a polar dial. However, the face of a polar dial need not be vertical; it need only be parallel to the gnomon.

In polar dials, the shadow-receiving plane is aligned parallel to the gnomon-style. Thus, the shadow…

View of a village in the Schwartzwald, or Black Forest. The Black Forest stands in the elbow formed by the Rhine river in its course from Schaffhausen to Basle, and from Basle to Mannheim. It is bounded by the plain that borders the river The Neckar River bounds it on the north, while on the east it is limited by the upper part of the same river, and by an imaginary line drawn from the source of the Neckar to Schaffhausen. The Black Forest owes its gloomy name to the dark aspect of its peaks and slopes which is shadowed by pine-trees. On the brightest day the forest's trees still retain their shadow.
