“A hair hygrometer,” he said to me, waving his wax-like hand over it. “The indications are obtained from the expansion and contraction of a prepared human hair, transferred to an index needle traversing the divided arc of—”
“What oil do you put on the human hair Jode?” called out the Governor, who had left our group, and was gamboling about by himself among the tubes and dials. “What will this one do?” he asked, and poked at a wet paper disc. But before the courteous Jode could explain that it had to do with evaporation and the dew-point, the Governor’s attention wandered, and he was blowing at a little fan-wheel. This instantly revolved and set a number of dial hands going different ways. “Hi!” said the Governor, delighted. “Seen ’em like that down mines. Register air velocity in feet. Put it away, Jode. You don’t want that to-morrow. What you’ll need, Hilbrun says, is a big old rain-gauge and rubber shoes.”
“I shall require nothing of the sort, Governor,” Jode retorted at once. “And you can go to church without your umbrella in safety, sir. See there.” He pointed to a storm-glass, which was certainly as clear as crystal. “An old-fashioned test, you will doubtless say, gentlemen,” Jode continued—though none of us would have said anything like that—“but unjustly discredited; and, furthermore, its testimony is well corroborated, as you will find you must admit.” Jode’s voice was almost threatening, and he fetched one corroborator after another. I looked passively at wet and dry bulbs, at self-recording, dotted registers; I caught the fleeting sound of words like “meniscus” and “terrestrial minimum thermometer,” and I nodded punctually when Jode went through some calculation. At last I heard something that I could understand—a series of telegraphic replies to Jode from brother signal-service officers all over the United States. He read each one through from date of signature, and they all made any rain to-morrow entirely impossible. “And I tell you,” Jode concluded, in his high, egg-shell voice, “there’s no chance of precipitation now, sir. I tell you, sir,”—he was shrieking jubilantly— “there’s not a damn’ thing to precipitate!”
