An Eclipse in Arabia.
Casting my eyes over the bright, full moon, I perceived that an eclipse was just coming upon it. What astronomer had calculated this eclipse for Arabia? It was indeed a privilege to witness one in the bright sky that over-spread the lonely mountains of Seir. Soon we were seated in a circle, with our Arabs round their watch-fire, enquiring of them their views of an eclipse, and explaining to them ours. They appeared to have no idea of its real cause, regarding it as a judgment from God, a sign of a bad season, and little camel feed. When we undertook to explain to them the theory of the earth being round, turning over every day, sometimes getting between the sun and moon, they seemed to look upon us as telling very strange tales. The eclipse was nearly total. I gazed upon it with interest, and then eyed the strange scene around me. The wild, lonely landscape of rock and sand--the camels kneeling round the bivouac--the wild faces of the Arabs, reflecting the red light of the fire round which they were seated--their wild voices and strange guttural language, all combined to produce an effect so startling, that I felt till then I had never been thoroughly sensible of our complete separation from the civilized world.
Giving Credit.
"One of our exchange" says one of our exchanges, "came to us this week with four of our editorials not credited." A frivolous complaint. Not a week passes but we find in some of our exchanges from ten to twenty of our editorials; and instead of complaining, we are thankful for being thus complimented.
The Bowie Knife and its Inventor.
This instrument was devised by Col. James Bowie, an American, and a man of desperate valor. He considered, and apparently with justice, too, that, in close fighting, a much shorter weapon than the sword ordinarily in use, but still heavy enough to give it sufficient force, and, at the same time, contrive to cut and thrust, would be far preferable, and more advantageous to the wearer. He accordingly invented the short sword, or knife, which has since gone under his name. It is made of various sizes; but the best, I may say, is about the length of a carving knife--case perfectly straight in the first instance, but greatly rounded at the end on the edge side; the upper edge at the end, for the length of about two inches, is ground into the small segment of a circle and rendered sharp; thus leaving an apparent curve of the knife, although in reality the upturned point is not higher than the line of the back. The back itself gradually increases in weight of metal as it approaches the hilt, on which a small guard is placed. The Bowie knife, therefore, has a curved, keen point; is double edged for the space of about a couple of inches of its length; and when in use, falls with the weight of a bill hook.--Bowie went to Texas during the troubles which preceded the independence of that country,--and was lying sick in bed at the fortress of the Alamo, when, on the 6th of March, 1836, it was stormed by Santa Anna and taken. Bowie was murdered there upon his pillow. The hand that formed the dreadful knife could no longer wield it.
Forests and Streams.
That remarkable man, Humbolt, has reduced it almost to a demonstration, that the streams of our country, fail in proportion to the destruction of its timber. And of course, if the streams fail, our seasons will be worse; it must get drier and drier in proportion. Humbolt, speaking of the Valley of Araguay in Venezuela, says that the lake receded as agriculture advanced, until the beautiful plantations of sugar-cane, banana and cotton-trees, were established on its banks, which (banks) year after year were farther from them. After the separation of that Province from Spain, and the decline of agriculture amid the desolating wars which swept over this beautiful region, the process of clearing was arrested, and old lands grew up in trees with that rapidity common to the tropics, and in a few years the inhabitants were alarmed by a rise of the waters, and an inundation of their choice plantations.
Prussian Music.
The Boston Brigade Band has been presented with a copy of the collection of the celebrated martial music of the Prussian army. Prussia has long been famous for the excellence of its military bands, and the music which they have produced is of the highest order. We hope this attempt to introduce it into our city will improve the style of martial music here.
Philosophy.
"Uncle Jo," said an observing little boy, "our folks always put up the window when the room is filled with smoke, and the wind always blows in so as to prevent the smoke from going out that way: now where does the smoke go?" "It goes into the people's eyes," was uncle Jo's philosophic answer.
Polite Preaching.
A certain preacher, when treating on the subject of repentance, said, "My dear hearers, you must repent; if you do not, you will go to a place which it would be improper to mention in this polite assembly."
Mr. H. Longfellow of Cincinnati, has about one hundred acres under culture of grapes, strawberries, peaches and raspberries.

Pure Air.
Fling the curtain aside and the blind,
And give a free entrance to heaven's pure air,
'Tis the life and health of mankind.
Behold that dull concourse in yonder closed space,
With visages sluggish and red;
How calmly they sit, each one in his place,
While their lungs with poison are fed.
What makes the grave deacon so drowsy at church?
The scholar so dull in his class?
Dry sermons!--dry studies!--the brain's in the lurch,
For want of pure oxygen gas.
Come, 'rouse, from your stupor, before it's too late,
And do not yourself so abuse--
To sit all day with your feet on the grate;
No wonder you're getting the "blues!"
Are you fond of coughs, colds, dyspepsia and rheums?
Of headaches, and fevers and chills?
Of bitters, hot-drops, and medicine fumes,
And bleeding, and blisters and pills?
Then shut yourself up like a monk in his cave,
Till nature grows weary and sad,
And imagine yourself on the brink of the grave.
Where nothing is cheerful and glad.
Be sure when you sleep, that all is shut out:
Place, too, a warm brick to your feet--
Wrap a bandage of flannel your neck quite about
And cover your head with the sheet.
But would you avoid the dark gloom of disease?
Then haste to the fresh open air,
Where your cheek may kindly be tanned by its breeze;
'Twill make you well, happy and fair.
O, prize not this lightly, so precious a thing;
'Tis laden with gladness and wealth--
The richest of blessings that heaven can bring,
The bright panacea of health.
Then open the window, and fasten it there!
Fling the curtain aside and the blind.
And give
