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.
