There was a fire in Lowell, as we judged, this night, and we saw the horizon blazing, and heard the distant alarm-bells, as it were a faint tinkling music borne to these woods. But the most constant and memorable sound of a summer's night, which we did not fail to hear every night afterward, though at no time so incessantly and so favorably as now, was the barking of the house-dogs, from the loudest and hoarsest bark to the faintest aerial palpitation under the eaves of heaven, from the patient but anxious mastiff to the timid and wakeful terrier, at first loud and rapid, then faint and slow, to be imitated only in a whisper; wow-wow-wow-wow--wo--wo--w--w. Even in a retired and uninhabited district like this, it was a sufficiency of sound for the ear of night, and more impressive than any music. I have heard the voice of a hound, just before daylight, while the stars were shining, from over the woods and river, far in the horizon, when it sounded as sweet and melodious as an instrument. The hounding of a dog pursuing a fox or other animal in the horizon, may have first suggested the notes of the hunting-horn to alternate with and relieve the lungs of the dog. This natural bugle long resounded in the woods of the ancient world before the horn was invented. The very dogs that sullenly bay the moon from farm-yards in these nights excite more heroism in our breasts than all the civil exhortations or war sermons of the age. "I would rather be a dog, and bay the moon," than many a Roman that I know. The night is equally indebted to the clarion of the cock, with wakeful hope, from the very setting of the sun, prematurely ushering in the dawn. All these sounds, the crowing of cocks, the baying of dogs, and the hum of insects at noon, are the evidence of nature's health or _sound_ state. Such is the never-failing beauty and accuracy of language, the most perfect art in the world; the chisel of a thousand years retouches it.

At length the antepenultimate and drowsy hours drew on, and all sounds were denied entrance to our ears.

Who sleeps by day and walks by night,
Will meet no spirit but some sprite.

SUNDAY.

"The river calmly flows,
Through shining banks, through lonely glen,
Where the owl shrieks, though ne'er the cheer of men
Has stirred its mute repose,
Still if you should walk there, you would go there again."
CHANNING.

"The Indians tell us of a beautiful River lying far to the south,
which they call Merrimack."

Sieur de Monts, _Relations of the jesuits_, 1604.

SUNDAY.

In the morning the river and adjacent country were covered with a dense fog, through which the smoke of our fire curled up like a still subtiler mist; but before we had rowed many rods, the sun arose and the fog rapidly dispersed, leaving a slight steam only to curl along the surface of the water.
