They counted my fingers several times, and then counted my toes.

But the thing about me which amazed them the most was my ears. These they studied for a long time, with much inaudible consultation, as I judged by the motions of their antennae.

Finally they took their departure, and Doggo came to me bristling with excitement, and apparently having much important information to impart; but, alas, he did not know my language, and he had no language at all. I patted him again, but this time it did not soothe him, for he broke away from me impatiently and returned to his station by the door.

Left to myself, I fell to studying the meter again, watching the counter-clockwise rotation of its hands. Even the left pointer had moved a bit since early morning.

Now I noticed, what I might have surmised on the analogy of an earthly gas meter, that each graduation of the central dial represented one complete revolution of the pointer on its right; and this principle presumably extended to the dial on its left. Then I counted chimpanzees again, and found that the right hand pointer was still rotating counterclockwise at the rate of about fifty chimpanzees per graduation. Counterclockwise! Why, perhaps this machine was a clock!

I made a hasty mental calculation: “One graduation equals fifty seconds. Twelve graduations—one complete rotation—equal six hundred seconds—ten minutes. Thus one graduation of the middle dial represents ten minutes, and its complete circuit, represents two hours. By the same token, a complete circuit of the left dial would represent twenty-four hours—one day!”

My guess was apparently correct.

At that time it did not occur to me as strange that a day on this planet should be twenty-four hours as on earth.

The figure to the left of the top of each dial was a single horizontal line, presumably standing for unity; for a single line, either horizontal or vertical, is the almost universal symbol for unity.

“Then,” said I, “the next figures must be two, the next figure three, and so on around to twelve. Eureka! I can now count up to twelve with these creatures; thus establishing, in writing at least, the beginning of a possible basis of communication.”

Eager to test my newfound knowledge, I beckoned to Doggo. He came to my side.
