While finding "equinox," however, I came across the word "equilibrium," which is the word before you come to "equinox," and I became quite absorbed in what it had to say on the matter. There were a great many things stated there that I had never dreamed before, even in my wildest vagaries on the subject of equilibrium. For instance, did you know that if you cover the head of a bird, "as in hooding a falcon" (do you remember the good old days when you used to run away from school to hood falcons?) the bird is deprived of the power of voluntary movement? Just think of that, deprived of the power of voluntary movement simply because its head is covered! And, as if this were not enough, it says that the same thing holds true of a fish! If you should ever, on account of a personal grudge, want to get the better of a fish, just sneak up to him on some pretext or other and suddenly cover its eyes with a cloth, and there you have it, helpless and unable to move. You may then insult it, and it can do nothing but tremble with rage. It is little practical things like this that you pick up in reading a good reference book, things that you would never get in ten years at college. For instance, take the word "equites," which follows "equinox" in the encyclopedia. What do you know about equites, Mr. Businessman? Of course, you remember in a vague way that they were Roman horsemen or something, but, in the broader sense of the word, could you have told that the term "equites" came, in the time of Gaius Gracchus, to mean any one who had four hundred thousand sesterces? No, I thought not. And yet that is a point which is apt to come up any day at the office. A customer from St. Paul might come in and, of course, you would take him out to lunch, hoping to land a big order. Where would you be if his hobby should happen to be "equites "? And if he should come out in the middle of the conversation with "By the way, do you remember how many sesterces it was necessary to have during the administration of Gaius Gracchus in order to belong to the Equites?" if you could snap right back at him with "Four hundred thousand, I believe," the order would be assured. And if, in addition, you could volunteer the information that an excellent account of the family life of the Equites could be found in Mommsen's "_Römisches Staatsrecht_," Vol. 3, your customer would probably not only sign up for a ten-year contract, but would insist on paying for the lunch.
