From A Cotswold Village (1899) by Joseph Arthur Gibbs:
There is no dog more knowing and sagacious in his own particular way than a well-trained retriever. What an immense addition to the pleasure of a day’s partridge-shooting in September is the working of one of these delightful dogs! Only the other day, when I was sitting on the lawn, a retriever puppy came running up with something in his mouth, with which he seemed very pleased. He laid it at my feet with great care and tenderness, and I saw that it was a young pheasant about a fortnight old. It ran into the house, and was rescued unharmed a few hours afterwards by the keeper, who restored it to the hencoop from whence it came. One could not be angry with a dog that was unable to resist the temptation to retrieve, but yet would not harm the bird in the smallest degree (pg. 320-321).
