The perpendicular height to which water will rise in a jet, has a limit depending upon the diameter of the jet, and on the specific gravity of the water, and on that of the air which it has to penetrate. A jet of salt water will rise higher than one of fresh water, a column six inches in diameter, higher than one of three inches; and a jet of water of any dimension higher at Madrid or Munich than in Paris or London, on account of the difference of the elevation of those cities above the level of the sea. The most powerful garden jet in Europe is that in the Nymphenburg Gardens near Munich. The water is there forced by the direct influence of machinery without the intervention of a head or reservoir: and it is found that a column of six inches in diameter cannot even there be raised higher than ninety feet. A similar column at St Cloud is said not to rise higher than sixty or seventy feet. It must be recollected that water boils at Munich at 200 degrees, whereas at St. Cloud it requires 212 degrees to effect ebullition.—Gardener's Magazine.
