NO doubt those who never hear the song of the Nightingale are denied a special privilege. Keats' exquisite verses give some notion of it, and William Drummond, another English poet, has sung sweetly of the bird best known to fame. "Singer of the night" is the literal translation of its scientific name, although during some weeks after its return from its winter quarters in the interior of Africa it exercises its remarkable vocal powers at all hours of the day and night. According to Newton, it is justly celebrated beyond all others by European writers for the power of song. The song itself is indiscribable, though numerous attempts, from the time of Aristophanes to the present, have been made to express in syllables the sound of its many notes; and its effects on those who hear it is described as being almost as varied as are its tones. To some they suggest melancholy; and many poets, referring to the bird in the feminine gender, which cannot sing at all, have described it as "leaning its breast against a thorn and pouring forth its melody in anguish." Only the male bird sings. The poetical adoption of the female as the singer, however, is accepted as impregnable, as is the position of Jenny Lind as the "Swedish Nightingale." Newton says there is no reason to suppose that the cause and intent of the Nightingales' song, unsurpassed though it be, differ in any respect from those of other birds' songs; that sadness is the least impelling sentiment that can be properly assigned for his apparently melancholy music. It may in fact be an expression of joy such as we fancy we interpret in the songs of many other birds. The poem, however, which we print on another page, written by an old English poet, best represents our own idea of the Nightingale's matchless improvisation, as some call it. It may be that it is always the same song, yet those who have often listened to it assert that it is never precisely the same, that additional notes are introduced and the song at times extended. The Nightingale is usually regarded as an English bird, and it is abundant in many parts of the midland, eastern, and western counties of England, and the woods, coppices, and gardens ring with its thrilling song. It is also found, however, in large numbers in Spain and Portugal and occurs in Austria, upper Hungary, Persia, Arabia, and Africa, where it is supposed to spend its winters. The markings of the male and female are so nearly the same as to render the sexes almost indistinguishable. They cannot endure captivity, nine-tenths of those caught dying within a month. Occasionally a pair have lived, where they were brought up by hand, and have seemed contented, singing the song of sadness or of joy.
