MY PREVIOUS ACQUAINTANCE WITH THE SUBJECT
I cannot remember whether it was in 1912, or earlier, or possibly even later, that I heard for the first time of Karl Krall's horses at Elberfeld. No details then reached me; only just the generalities relative to their ability to count and spell. Of their fore-runner, "der kluge Hans," I had as yet heard nothing. I had been a child when Hans had made his début, so to speak; he had then vanished and the odium which had later attached to his name was, therefore, unknown to me. I may say that I was totally unprejudiced when the news of these horses reached and, indeed, as there was but little information I did not interest myself further about the subject, although it had made a momentary impression on me. A year or two later Professor Kraemer of Hohenheim arrested public attention by his investigations respecting animals, and it was there that I heard him deliver a lecture on the horses and also the dog Rolf of Mannheim, hearing further details from him in conversation with my father[11 ] and myself. What I then heard interested me immensely.
Professor Kraemer was a keen advocate of this subject, but I was chary of forming any opinion without deeper investigations. The possibility of "self-expression" on the part of animals did not seem to me to be beyond the bounds of belief, even though some examples which were supposed to attest to high intelligence seemed to me a little doubtful. I tried to get more information, but was hindered at the time owing to the three years' course of studies I was then pursuing at the Hohenheim School of Agriculture, so that I was neither able to try any experiments on my own part, nor even to read Krall's great work on the subject. The entire question, therefore, remained an open one—as far as I was concerned, although my father had been to Elberfeld to see the horses, and had,—after making personal tests—come to the conclusion that everything was above-board and in accordance with what it claimed to be and that the animals really did give answers which were the outcome of their own independent thinking. In addition to this I read the public communications made by Professor Ziegler at Stuttgart, as well as also his own personal opinions.
Both these gentlemen, Professor Ziegler, as well as Professor Kraemer, were known to me only in their capacity of serious and conscientious investigators, men upon whose judgment I might safely rely, so long as my own experience did not oblige me to take up a different standpoint. And further, I skimmed over everything that the Press brought forward of an opposing nature, so that I might know their point of view as well.
After I had passed my Academic Examination, and taken my Diploma, I took over, some six months later, the independent management of a big estate in the Rheinland, which consisted of three hundred acres. (I was able to do this on the strength of some practical experience I had had previously in Thüringen apart from my studies.)
After a year and a half I felt sufficiently at home at the work to be able to turn my attention to such matters of interest as lay outside that of my daily work, and I now called to mind the subject of the "Thinking Horses," deciding to attempt some experiments. The approach of such a solitary season as winter seemed to me particularly suited to this attempt and I placed myself in communication with Professor Ziegler so as to hear of a likely animal. It was to be a dog, and—for preference—a relation of Rolf. Indeed, I felt sure of excellent results, should my quest meet with success. A dog is of all animals the one that has for generations associated most with man; its attachment is of the most intimate and the most faithful nature, so that by inheritance, as it were, it would seem to be in a greater state of "preparedness" for fulfilling man's behests. Horses, oxen, asses, pigs, and poultry, etc., are each and all, of course, accustomed to the guidance of man's hand, but—here in Europe, at all events—they live their lives apart and are not so domesticated; they cannot, therefore, form so intimate an acquaintance with man, by means of eye and ear, as can enable them to comprehend both language and gestures. For practical purposes horses would seem to come next to dogs in the matter of intelligence—more particularly Arab horses. An Arab talks to his horse as he would to a friend, and the sparkle in the eye of this animal denotes its intelligence. In the matter of actual sensibility, the ox, the ass, and other creatures have practically nothing in common with us, showing an utterly foreign type of intelligence, and one, moreover, which has—owing to the existent century-old customs of keeping them isolated in their stalls—depressed even such intelligence as was originally theirs. Creatures of the wild seem only in exceptional cases to prove amenable to training, however great their intelligence may be they cannot adapt themselves to man's control, and can as a rule only imitate, seldom revealing to us any gleam of mental alertness.
Professor Ziegler recommended a bitch which was a descendant of Rolf's and advised me to pay a visit to Mannheim. I did so, and our interview was most satisfactory. It lasted three-quarters of an hour, by which time I had assured myself that the dog could answer, even though he did not tap my hand, but rapped out his remarks on a piece of cardboard held by Fräulein Moekel. Here is the account of my visit:
"Report of Fräulein Kindermann of her
Visit to the Family of Dr. Moekel, in Mannheim,
11 January, 1916.
"After hearing much about the 'thinking animals,' more particularly about the dog Rolf, and having also with great enthusiasm read everything I could find on the subject, I became obsessed with the desire to embark on this study, forming my opinion by tests carried out myself, thus personally being in a position to approach the subject with the requisite scientific accuracy.
