How sensibly animals are equipped as to the requisites of life! Probably man was, too--at one time; at a time when he stood nearer to Nature, and before his inventions and manifold accessories had weaned him from so much that was inherent and inborn knowledge. CALCULATING TIME At first I proposed to achieve this by building on the foundations I had already laid, on the dog's fairly reliable comprehension of the value of figures, and her knowledge of spelling. So I wrote on a large sheet of paper and in small characters:[14] 1 jar (jahr = year) = 365 days. 7 tage ( = days) = 1 woche ( = week). so for 1 jar = 52 wochen = 365 tage. The days of the week are called:-- 1 montag. 2 dinstag (dienstag). 3 mitwoch (mittwoch). 4 donerstag (donnerstag). 5 freitag. 6 samstag. 7 sontag (Sonntag); no work for Lola! [14] So as to avoid confusing her I always write the _sound_ only. This was to be--at the same time--a test of Lola's reading. I placed the chart on the floor where she could look at it, and repeated: "To-morrow you must be able to know this. Now spell the first word to me. And she tapped "jar." I once more went over this new lesson, explaining it all, but put no more questions, only leaving the paper where she could from time to time look at it. The next day I removed the chart early, and later began my questioning; fully prepared for somewhat crazy results. First I asked: "How many days are there in a week?" She rapped "7." "And in three weeks?" "21." "How many weeks has a year?" "52." I praised her warmly--her interest seemed roused, for she had rapped her answers with a sort of joyful certainty! So I continued: "Name the second day in the week?" "dinstag!" "And what is the day called on which you do no work?" "sontag!" "And which day in the week is that?" "7."
