As may readily be imagined, it is by no means easy to induce an animal to work with any person it does not regard as its accepted teacher. On such occasions, it will behave like a small child, and be restless and even intractable. Often, too, while apparently willing, there may be something unfamiliar in the way in which a question is put (a matter for which no one can be blamed!), this resulting in the impossibility of getting an answer. Sometimes, too, the hand proffered to receive the replies is not held either straight or flat enough, or may not have the right slant that will enable the paw to rap without slipping off. Or, again a hand will be held too high, and thus cause much inconvenience to the animal. Then too, questions are carelessly worded, and seem strange to the method of thought to which its regular instructor has accustomed it, fresh explanations being then required to achieve any results at all. And so it comes, that only those can work successfully with animals who have already been frequently present at the teaching, and are then willing to try their luck, calmly and tranquilly--and quite alone with the animal, so as to carefully develop their own aptitude, as well as gain the confidence of their charge. It is true that in the case of the horses, others, besides Herr Krall, frequently did work with them. Indeed, my father got excellent answers from them, although he had to do with them for only a short time. But the matter seems rather more difficult with dogs; for one thing, they do not stand in front of a board--independently, so to speak--as do the horses; nor are they, from the beginning of their career as habitually accustomed to a variety of persons about them, at least, not to the extent that horses are. And yet they are sometimes quite ready to work with others, this being the case with Lola when I took her to Stuttgart, on a visit to a lady she already knew--Fraeulein M. D., and who had put a few questions to her when here at the farm, questions which she had answered quite correctly. At Stuttgart there was a larger circle of listeners, and Lola sat in their midst upon a table. Fraeulein M. D. stood beside me, and I asked her to put the question. I do not now remember what the question was, but I had extended my hand for the reply. Lola, however, turned to the speaker, and tapped the correct answer on that lady's arm, giving the second--and equally good one on Fraeulein M. D.'s proffered hand. Lola is also in the habit of answering my people with either "yes" or "no" as the case may be, and on one occasion--when I was away from home, having gone to Munich for three weeks--she remained with Frau Kindermann at Hohenheim, and during that time, gave replies to all kind of questions put to her by that lady, as the following report will show: "REPORT OF FRAU PROFESSOR KINDERMANN IN HOHENHEIM
