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.
