An instrument used to measure the quantity of a rain which falls at a given place. They are which falls at a given place. They are variously constructed. A convenient form (shown in figure) consists of a cylindrical tube of copper, with a funnel at the top where the rain enters. Connected with the cylinder at the lowest part is a glass tube with an attached scale.

"The campaign in Georgia. A baggage train crossing the mountains in a storm. General Sherman, after the capture of Atlanta, prepared for the next move of his antagonist. Hood suddenly moved north, assailing Sherman's lines of communication; but he was repulsed at important points, and, being followed closely by Sherman, retreated southward. The mountain region was again the scene of operations just as winter was approaching. The immense labor and fatigue attendant on operations in that district may be conceived by our sketch of a baggage train crossing the mountains in a storm."— Frank Leslie, 1896

Cirrus cloud is a type of cloud composed of ice crystals and characterized by thin, wisplike strands, often accompanied by tufts. A Cumulus cloud is a cloud belonging to a class characterized by puffs, mounds or towers, with flat bases and tops that often resemble cauliflower.

A Nimbus, or Storm Cloud, is any cloud from which rain falls. The Stratus, or Layer Clouds, form in long, horizontal sheets or bands. These clouds are most common in the early morning or evening, when the ascending currents are weak.

An instrument or contrivance for measuring the amount of rain which falls on a given surface. They are made of various forms. One simple form consists of a copper funnel five to seven inches in diameter, inserted in the neck of a bottle placed on a stand and protected from the sun's rays, to prevent evaporation.

The wind is supposed to rotate as in a cyclone, only the axis of the whirl is horizontal instead of vertical. Two horizontal layers of cloud exist-the upper layer of snow, the lower, or rain. The snowflakes, which form the nuclei of the hailstones, are caught in the whirl, are dipped in rapid succession into the two clouds, thus receiving alternate coatings of ice and snow, until at last they are hurried to the ground.

"In meteorology, a subsidiary cyclonic circulation, generally on the border of a primary cyclone accompanied by rain, thunder-storms, and squalls: indicated on a weather-map by the bulging of a sea-level isobar toward the region of higher pressure." -Whitney, 1911

Cirro-Cumulus is formed from cirrus or cirrostratus clouds when they are warmed gently from below. Cirro-Stratus clouds appear as whitish and usually somewhat fibrous veils, often covering the whole sky and sometimes so thin as to be hardly discernible. The Cumulo-Stratus is the form produced by the heaping together of a mountain-like mass of cumulus clouds.

"The warmer current ascends, as indicated by the small arrows, and curls at the black wreath (u) of cloud, and then the commingling of the two currents forms an imposing dark dome (v) of cloud, from which heavy rain (r) or hail descends. The light grayish cloud which is seen behind the black wreath is the rain descending from the dark dome. The heavy raindrops bring down a large quantity of cold air, which flies straight out in advance of the storm, and produces the squall (q) indicated by the long arrow."—Finley, 1917

Concentric layers, similar to those of an onion, will be noticed, arranged around a central nucleus, sometimes of ice and sometimes of snow, through generally the latter. The stones are more or less oblately spheroidal in shape. Their general weight varies from a few grains to several ounces, but they have been known to way several pounds.
