There is a renewed agitation of late to abolish Latin from our curricula. Had I not known my Latin I never could have figured out what "equinox" meant, and this article would never have been written. Take that, Mr. Flexner!

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.

But, of course, this has practically nothing to do with Spring, or, as the boys call it, the "vernal equinox." The vernal equinox is a serious matter. In fact, I think I may say without violating any confidence, that it is the initial point from which the right ascensions and the longitudes of the heavenly bodies are measured. This statement will probably bring down a storm of ridicule on my head, but look at how Fulton was ridiculed.

In fact, I might go even further and say that the way to seek out Spring is not to trail along with the poets and essayists into the woods and fields and stand about in the mud until a half-clothed bird comes out and peeps. If you really want to be in on the official advent of Spring, you may sit in a nice warm observatory and, entirely free from head-colds, proceed with the following simple course:

Take first the conception of a fictitious point which we shall call, for fun, the Mean Equinox. This Mean Equinox moves at a nearly uniform rate, slowly varying from century to century.

Now here comes the trick of the thing. The Mean Equinox is merely a decoy, and, once you have determined it, you shift suddenly to the True Equinox which you can tell, according to Professor A.M. Clerk's treatise on the subject, because it moves around the Mean Equinox in a period equal to that of the moon's nodes. Now all you have to do is to find out what the moon's nodes are (isn't it funny that you can be as familiar with an object as you are with the moon and see it almost every night, and yet never know that it has even one node, not to mention nodes?) and then find out how fast they move. This done and you have discovered the Vernal Equinox, or Spring, and without spilling a dactyl.
