Cf. Shakespeare, M. W. iv. 2. 209: "If I bark out thus upon no trail never trust me when I open again."

The description of the echo which follows is very spirited.

66. Cairn. Literally, a heap of stones; here put poetically for the rocky point which the falcon takes as a look–out.

69. Hurricane. A metaphor for the wild rush of the hunt.

71. Linn. Literally, a deep pool; but often cataract, as in Bracklinn, ii. 270 below (cf. vi. 488), and sometimes precipice.

73. On the lone wood. Note the musical variation in the measure here; the 1st, 3d, and 4th syllables being accented instead of the 2d and 4th. It is occasionally introduced into iambic metre with admirable effect. Cf. 85 and 97 below.

76. The cavern, etc. See on 53 above.

80. Perforce. A poetical word. See on 46 above.

84. Shrewdly. Severely, keenly; a sense now obsolete. Shrewd originally meant evil, mischievous. Cf. Shakespeare, A. Y.
