What is wanted is the careful preservation and collection of instances of exceptional intelligence. III. Before I conclude this Introduction, I should like to address a word of apology to the correspondents of the _Spectator_ whose letters form the present volume. Though the copyright of the letters belongs to the editors and proprietors of the _Spectator_ I should have liked to ask the leave of the various writers before republishing their letters. Physical difficulties have, however rendered this impossible. In the case of nearly half the letters the names and addresses have not been preserved. In many instances, again, only the names remain. Lastly, a large number of the letters are ten or twelve, or even twenty years old, and the writers may therefore be dead or out of England. Under these circumstances I have not made any effort to enter into communication with the writers before including their letters in this book. That their permission would have been given, had it been asked, I do not doubt. The original communication of the letters to the _Spectator_ is proof that the writers wished a public use to be made of the anecdotes they relate. As long, then, as the letters are not altered or edited, but produced verbatim, I may, I think, feel assured that I am doing nothing which is even remotely discourteous to the writers. _SYLLOGISTIC DOGS._ A DOG ON LONG SERMONS. [_Aug. 4, 1888._] During a recent journey in Canada, I met with a striking instance of reason in a dog. I was staying at the Mohawk Indian Institution, Brantford, Ontario. The Rev. R. Ashton, superintendent of the school, is also incumbent of the neighbouring Mohawk Church (the oldest Protestant church in Canada). Mr. Ashton is very fond of animals, and has many pets. One of these, a black-and-tan terrier, always accompanies the ninety Indian children to church on Sunday morning. He goes to the altar-rails, and lies down facing the congregation. When they rise to sing, he rises; and when they sit, he lies down. One day, shortly before my visit, a stranger-clergyman was preaching, and the sermon was longer than usual. The dog grew tired and restless, and at last a thought occurred to him, upon which he at once acted. He had observed that one of the elder Indian boys was accustomed to hand round a plate for alms, after which the service at once concluded. He evidently thought that if he could persuade this boy to take up the collection, the sermon must naturally end. He ran down to the back seat occupied by the boy, seated himself in the aisle, and gazed steadfastly in the boy's face. Finding that no notice was taken, he sat up and "begged" persistently for some time, to Mr. Ashton's great amusement. Finally, as this also failed, the dog put his nose under the lad's knee, and tried with all his strength to force him out of his place, continuing this at intervals till the sermon was concluded. Did not this prove a distinct power of consecutive reasoning?
