He many times deceives the sportsman, and sends him in search of birds that perhaps are not within miles of him, but whose notes he exactly imitates. Even birds themselves are frequently imposed on by this admirable mimic, and are decoyed by the fancied...
第 198 頁 - By the time the cayman was within two yards of me I saw he was in a state of fear and perturbation. I instantly dropped the mast, sprung up and jumped on his back, turning half round as I vaulted, so that I gained my seat with my face in a right position.

第 267 頁 - The feathers when thoroughly moistened will sink down, and should remain in the limewater three or four days ; after which the foul liquor should be separated from them by laying them in a sieve. The feathers should be afterwards well washed in clean water, and dried upon nets, the meshes of which may be about the fineness of cabbage-nets. The feathers must be from time to time shaken on the nets, and as they dry will fall through the meshes, and are to be collected for use.
