It is on such occasions, if we are in a moralizing mood, that we may be keenly impressed with the truth of the saying, that the secret of happiness consists in keeping alive our susceptibilities by frugal indulgences, rather than by seeking a multitude of pleasures, that pall in exact proportion to their abundance. The stillness and darkness of a quiet night produce this enlivening effect upon our minds. Our susceptibility is then awakened to such a degree, that slight sounds and feeble sparks of light convey to our souls an amount of pleasure which we seldom experience in the daytime from sights and sounds of the most pleasing description. Thus the player in an orchestra can enjoy such music only as would deafen common ears by its crash of sounds, in which they perceive no connection or harmony; while the simple rustic listens to the rude notes of a flageolet in the hands of a clown with feelings of ineffable delight. Nature, if the seekers after luxurious and exciting pleasures could but understand her language, would say to them, "Except ye become as this simple rustic, ye cannot enter into my paradise." The American Snipe has some of the nocturnal habits of the Woodcock, and the same habit of soaring at twilight, when he performs a sort of musical medley, which Audubon has very graphically described in the following passage:--"The birds are met with in meadows and low grounds, and, by being on the spot before sunrise, you may see both (male and female) mount high, in a spiral manner, now with continuous beats of the wings, now in short sailings, until more than a hundred yards high, when they whirl round each other with extreme velocity, and dance, as it were, to their own music; for, at this juncture, and during the space of five or six minutes, you hear rolling notes mingled together, each more or less distinct, perhaps, according to the state of the atmosphere. The sounds produced are extremely pleasing, though they fall faintly on the ear. I know not how to describe them; but I am well assured that they are not produced simply by the beatings of their wings, as at this time the wings are not flapped, but are used in sailing swiftly in a circle, not many feet in diameter. A person might cause a sound somewhat similar by blowing rapidly and alternately, from one end to another, across a set of small pipes, consisting of two or three modulations. This performance is kept up till incubation terminates; but I have never observed it at any other period." Among the Heron family we discover a few nocturnal birds, which, though not very well known, have some ways that are singular and interesting. Goldsmith considered one of these birds worthy of introduction into his "Deserted Village," as contributing to the poetic conception of desolation. Thus, in his description of the grounds which were the ancient site of the village, we read,-- "Along its glades, a solitary guest, The hollow-sounding Bittern guards its nest."
