[Illustration: (musical notation) NOTE.--The notes marked _guttural_ seem to me to be performed by a rapid trilling of these notes with their octave. It should be added, that no bird sings constantly in so regular time as is represented above, and the intervals between the high and low notes are very irregular. Both the time and the tune are in great measure _ad libitum_] [Illustration: SONG OF THE LINNET. (_Fringilla purpurea_.) (musical notation)] [Illustration: SONG OF THE WREN. (_Trogledytes fulvus_.)

[Illustration: Musical staff] Tu lu lu, tu lu lu, tu lu lu, too loo. NOTE.--The Robin is continually varying his notes; so that the two specimens, as given above, may be considered but the theme upon which he constructs his melody. SONG OF THE WARBLING VIREO. (_V.

His drawings of the same are beautifully executed, accompanied by representations of the nests and of the foliage that surrounded them. This gentleman and his brother, Mr. S.P. Fowler, have found leisure, during the intervals of their occupation in a mechanical art, to acquire a knowledge of certain branches of natural history which would do honor to a professor.] THE OLD WELL. On a bright April morning many years ago, a stout, red-faced old gentleman, Geoffrey Purcill, followed by several workmen bearing shovels and pick-axes, took his way to a little knoll on which stood a wide-spreading chestnut-tree. When they reached the top of the knoll, the old man paused a moment and then struck his gold-headed cane upon the ground at some little distance from the trunk of the tree, saying, "Dig here." The workmen looked at each other and then at their master. "It would be useless to dig a well here, Sir," said one of the workmen, very respectfully,--"no water would ever come into it." "Who asked for your opinion?" inquired Geoffrey, in an angry tone. "Do as I bid you;--the well shall be digged here, and water _shall_ come into it." The man ventured no further remonstrance; he took off his jacket, and struck his pickaxe into the hard, dry soil near the point where the cane rested.
