Green Paints are for the most part compounds of copper and of chromium. The best known greens are the following: Bremen green, or verditer, consisting mainly of a basic carbonate of copper. Brunswick green, a hydrated oxychloride of copper; but the name is sometimes given to a hydrated basic carbonate, also known as mountain green. Chrome and emerald green are oxide of chromium. Emerald green is also used as synonymous with Schweinfurt green. English green is a mixture of Scheele's green with gypsum. Guignets green is oxide of chromium prepared in a peculiar way. Hungary green is a kind of malachite found in Hungary. Rinman's green is obtained by heating zinc oxide with a cobalt compound. Saxony green is an indigo colour used in printing. Scheele's green is arsenite of copper, and Schweinfurt green, Veronese green, and Vienna green, are also compounds of arsenic and copper. Verdigris is a hydrated basic carbonate of copper, often seen in copper coins. Besides these are green colours derived from plants. Of these may be mentioned chlorophyll, the green colour of leaves: sap green, the juice of Rhamnus catharticus or buckthorn, made into a green lake with alumina; Chinese indigo-green, etc.

HUMMING-BIRD

Humming-bird is the popular name for the Trochilidae family of minute and beautiful birds, so called from the sound of their wings in flight. The beak is slender, generally long, sometimes straight and sometimes curved. The tongue is long and filiform. They feed by hovering by a plant and use their tongue to catch insects.

In size humming-birds vary from that of a wren to that of a humble-bee. They never light to take food, but feed while on the wing, hovering before a flower, supported by a rapid vibratory movement of the wings which produces the humming noise. These beautiful birds are peculiar to America, and almost exclusively tropical. One species, the ruby-throated humming-bird (Trochilus colubris) is pretty common in the north-east of the United States. The only note of the humming-bird is a single chirp, not louder than that of a cricket. It is very fearless and irascible, two males scarcely ever meeting without a contest. Among the more remarkable of these birds is the tufted-necked humming-bird (Ornismya ornata) of Guiana and Northern Brazil. In this species the crest, outer tail-feathers, and neck-plumea are reddish chestnut, the latter tipped with green, the throat and upper part of the breast are emerald green, the back bronze green.
