"'Lola shall have a good time with me; she shall run about in the woods and the meadows, and play with a lot of other animals, and not have to work too long; the professors shall be sent away when Lola is tired.' This evidently pleased him, and he became very friendly to me, and on my returning to my point and asking once more whether Lola might go with me, he rapped out his answer on my hand: it was 'Yes!' "Then I told him about an ox, who, when he didn't want to work, pretended to be dead. Rolf now got very excited, and wanted to go on rapping--first on my hand, and then on the leather-covered sofa on which I was sitting. I became rather uneasy and got him to go and rap to Fraeulein Moekel, for I could then follow the raps far better. And what he now had to say referred to the deceitful ox--it was: "Hat Recht: Lol immer sagen Bauchweh!" ( = Quite right of him! Lol always says he has a pain in his stomach!) "After this I showed him another box of biscuits, with a picture of a little nigger-boy on the lid, and asked: "'What do you see on this?' "To which he eagerly replied: "'Wuest schwarz Bub!' ( = A wild black boy!) "Rolf then received his reward, and I took a grateful leave of the Moekels--accompanied by little Lola. "This experience of coming into personal contact with Rolf's powers of self-expression made a deep and lasting impression on me. In spite of all the accounts I had read and heard this living proof was almost overpowering in its utter novelty, and in the feeling of emotion that came over me, I seemed to sense that 'Souls' Unrest' that a transition from the old conception of 'unreasoning' animals to this new cognition is bound to bring with it. "My visit had been so short that I had not been able to put any questions as to the method of instruction pursued. I had not been able to experiment personally nor get any actual advice, for Frau Dr. Moekel had died in the autumn of 1915. Yet I was by no means displeased at my state of ignorance when I came to reflect on the matter, for it enabled me to 'blaze a trail,' as it were, according to my own way of thinking, perhaps even, enabling me to arrive accidentally at similar or, diametrically opposite results!" LOLA Lola is an Airedale terrier, born at Mannheim on 27 January, 1914, a daughter of Rolf, and of the equally thorough-bred Jela. Both these dogs were owned by the family of a barrister, Dr. Moekel. The Airedale terrier resembles the dog we call a "Schnauzer"; it is wire-haired and of medium growth; generally with a greyish-black coat and yellow feet. Its head is covered with silky curls beneath which two bright eyes are seen. These dogs are distinguished for their alert and attentive bearing, while their excellent constitution renders them specially suitable for being trained to useful pursuits; they are at the same time not an over-bred race. Professor Heck, writing on the subject of these dogs (see "Communications of the Society for Animal Psychology"), says:
