I have read from time to time in the pages of the _Spectator_ instances of canine sagacity furnished by your correspondents, which have, no doubt, interested many others besides myself. The following incident occurred last Saturday, in my walk from the beach, which, perhaps, may amuse your readers, as it did me. My curiosity was excited by seeing a young retriever on his hind legs licking very ardently the face of a nice-looking donkey, who was tethered on the bank. After licking his face all over for a long time, he began to frisk around him, evidently anxious to have a trot together; but, finding that his friend was tied by a rope, he deliberately began to gnaw it, and in a very short time succeeded in setting him free! The owner of the donkey, who happened to be at work close by, then interfered, and put a stop to their little game, or otherwise Master Neddy would, no doubt, have been seduced to join in a scamper. From the warmth of the dog's salutes, I imagine that he and the donkey were old friends. S. RICHARDS. DOG AND CANARY. [_Nov. 20, 1880._] I was much interested in the account of the friendship that existed between the young retriever and the donkey whom he released by gnawing the rope. The little incident I send of another retriever may also interest your readers. A friend of mine had a pet canary, while her brother was the owner of a retriever that was also much petted. One day the canary escaped from the house, and was seen flying about the grounds for a few days, and when it perched was generally on high elm-trees. At last it vanished from view, and this dear little pet was mourned for as lost or dead. But after the interval of another day or so, the retriever came in with the canary in his mouth, carrying it most delicately, and went up to the owner of the bird, delivering it into her hands without even the feathers being injured. Surely nothing could illustrate more beautifully faithful love and gentleness in a dog than this. E. TILL. CAT-AND-DOG LOVE. [_April 13, 1878._]
