WEED DESTROYER

Man's enemies are not by any means confined to those he meets in his daily work. He has soul enemies which he has to reckon with constantly. Just as sure as the farmer can depend on a certain preparation to kill weeds, so can man depend upon a higher power to keep down and destroy our open and secret sins.

There is no dispute that we must meet the weed question with a certainty of success and at the same time it must be done in a very economical manner. In addition to what we may do with our cultivators and weeders and the growing of such crops as rye and winter wheat, by which we can destroy a certain class of weeds before they mature seed, we can also add that there is a system of weed destruction which is found in spraying. This is a matter which has come to the knowledge of men during the past few years. I learn from my reading that the first step in this direction was taken by a party in France. From that beginning it was taken up by men here in America, and it has now assumed a very practical form. The first spray was copper sulfate, or blue-*stone, but this would be somewhat difficult to obtain. The present material which is largely used is a by-product turned out by the steel-mills. This is called sulfate of iron. This by product has been thrown away, but now it can be used for the destruction of weeds by making a solution of it and spraying fields that are infested with a certain class of weeds.—, The Northwestern Agriculturist.

WEEDS, WARFARE AGAINST

Charles H. Spurgeon once said:

An old wall is so interpenetrated—every nook, crack and crevice—by the notorious ivy that, tho you may cut the vine at the roots, you can never thoroughly destroy it, till the wall itself is leveled.

Most weeds spread chiefly from their seeds, hence care should be taken to prevent the formation of weed-seeds. The more thorough we are in keeping out weeds, the easier our work. While we may not hope to get rid of all weeds, we may greatly lessen their numbers by keeping up a continual warfare against them.

WEIGHT DIMINISHED BY ASCENT

A writer, speaking of variation to be seen in the column of mercury in a barometer, says:

If you prop up the tube, and watch it carefully from day to day, you will find that the height of the column of mercury will continually vary. If you live at the sea-level, or thereabouts, it will sometimes rise more than thirty inches above the level of the mercury in the cup, and frequently fall below that height. If you live on the top of a high mountain, or on any high ground, it will never reach thirty inches, will still be variable, its average height less than if you lived on lower ground; and the higher you get the less will be this average height of the mercury.

The reason of this is easily understood. When we ascend a mountain we leave some portion of the atmosphere below us, and of course less remains above; this smaller quantity must have less weight and press the mercury less forcibly. If the barometer tells the truth, it must show this difference; and it does so with such accuracy that by means of a barometer, or rather of two barometers—one at the foot of the mountain and one on its summit—we may, by their difference, measure the height of the mountain provided we know the rules for making the requisite calculations.

The higher one ascends, the less weight oppresses the climber. This is a truth also of the moral life. The higher one ascends, the less obstacles and weights he encounters. In the valley the demoniac writhes; on the mountain top Christ appears in His glory.
