Next to the dog there is no animal in which there is more variation of sound than in oxen: "Their lowing, though rough and rude, is music to the farmer's ear save one who moans the loss of her sportive young; with wandering eye and anxious look she grieves the livelong day." It is specially difficult in the case of oxen to suppose that they have a language; but it is impossible to doubt that the variations of their lowing are understood of one another, and serve to express their feelings if not their thoughts. [Illustration] [Illustration: COW LOWING.] In the matter of exclamations, one knows how readily these may be imitated upon the violin, or in the case of the deeper or more guttural sounds, on the violoncello. The natural effect is greatly aided by the sliding of the finger along the note, especially in the case of the lowing of cattle; but there are other exclamations that are readily reduced to music. Gardiner gives one or two interesting cases, and the common salutation, "How d'ye do?" may be instanced. It usually starts on B natural, and the voice rising to D ends on C; whereas, the reply, "Pretty well, thank you," begins on D, and falling to A, ends again on D. After a few attempts on the piano, the reader will be able readily to form these notes for himself. [Illustration] [Illustration: HORSE NEIGHING.] The horse, on the other hand, is rarely heard, and, though having a piercing whinny which passes through every semitone of the scale, it is scarcely ever varied. [Illustration: THE CHIRP OF THE GRASSHOPPER.] The music of the insects has already been alluded to, and everyone will agree with Gilbert White that "not undelightful is the ceaseless hum, to him who musing walks at noon." The entomologist has laboured hard to show us that the insect has no voice, and that the "drowsy hum" is made by the wings; a fact which, being beyond all cavil, puts to the blush the old-world story of Plutarch, who tells us that when Terpander was playing upon the lyre, at the Olympic games, and had enraptured his audience to the highest pitch of enthusiasm a string of his instrument broke, and a _cicada_ or grasshopper perched on the bridge supplied by its voice the loss of the string and saved the fame of the musician. To this day in Surinam the Dutch call them lyre-players. If there is any truth in the story, the grasshopper then had powers far in advance of his degenerated descendants; for now the grasshopper--like the cricket--has a chirp consisting of three notes in rhythm, always forming a triplet in the key of B. [Illustration] [Illustration: FLY BUZZING.] [Illustration] [Illustration: DUCK.] Gardiner, on the authority of Dr. Primatt, states that, to produce the sound it makes, the house-fly must make 320 vibrations of its wings in a second; or nearly 20,000 if it continues on the wing a minute. The sound is invariably on the note F in the first space. The music of a duck's note is given in the annexed score.
