Their patience and endurance were very great when pursuing wounded ducks through the floating ice, and when fatigued from extraordinary exertions were known to rest themselves upon broken portions of ice till sufficiently recovered again to commence the chase. We have seen some of the descendants of these sagacious animals on the Chesapeake, engaged, not only in bringing the ducks from the water when shot, but also toling them into shore within range of the murderous batteries concealed behind the blind. This may not be an inappropriate place to speak of this wonderful mode of decoying ducks, termed toling, so extensively practised upon the Chesapeake bay and its tributaries, where the canvass-back and red-heads resort in such numerous quantities every fall. A species of mongrel water-dog, or often any common cur, is taught to run backwards and forwards after stones, sticks, or other missiles thrown from one side to the other. In his activity and industry in this simple branch of education, within the comprehension of any dog, consists the almost incredible art of toling the canvass-back. With a dog of this character, the shooting party, consisting of several persons all prepared with heavy double-barrelled duck-guns, ensconce themselves at break of day behind some one of the numerous blinds temporarily erected along the shore contiguous to the feeding-grounds of these ducks. Everything being arranged, and the morning mists cleared off, the ducks will be seen securely feeding on the shallows not less than several hundreds of yards from the shore. The dog is now put in motion by throwing stones from one side of the blind to the other. This will soon be perceived by the ducks, who, stimulated by an extreme degree of curiosity, and feeling anxious to inform themselves as to this sudden and singular phenomenon, raise their heads high in the water and commence swimming for the shore. The dog being kept in motion, the ducks will not arrest their progress until within a few feet of the water's edge, and oftentimes will stand on the shore staring, as it were, in mute and silly astonishment at the playful motions of the dog. If well trained the dog takes no notice whatever of the duck, but continues his fascination until the quick report of the battery announces to him that his services are now wanted in another quarter, and he immediately rushes into the water to arrest the flight of the maimed and wounded, who, struggling on every side, dye the water with their rich blood.
