"Every kind of brick, cement, and lime manufacture has got to be protected from the rain, and twenty-four hours' notice enables all such factories to protect their product. Contractors for outdoor work make their estimates and contracts on the basis of weather forecasts, railroad companies provide against washouts, and irrigation companies control their output of water according to the expected rainfall."
"This is great stuff," said Fred, under his breath to Ross. "I'm going to run this in the Review!"
"Snow warnings," the Forecaster went on, "are of equal value. All over the western country, where the snows are apt to be heavy, the tonnage of passenger and freight trains is made up in accordance with the expected weather, and the snow-fighting equipment is prepared. On the great Western ranches, stock is hurried from the open range either to constructed shelters or to naturally protected gullies, on notice of blizzards, northers and heavy snows. This is especially necessary on sheep ranches. Twenty-four hours' notice of a heavy snow-storm saves the country at least half a million dollars in stock loss and property damage.
"Storm warnings, perhaps, are even more important. Hundreds of lives are saved, every year, by vessels remaining in port when a storm or hurricane is expected. A recent storm on the Great Lakes was forecast as being so severe that scarcely any vessels left port. Many ships, undoubtedly, would have foundered, had they been out in the gale. Yet, aside from the Weather Map, there was no local indication that bad weather was brewing. When storm warnings are issued, fishermen take steps to protect their boats and nets and a fisherman's boat and net is his whole livelihood. Lumbermen make their booms of logs secure. Rice-planters flood their crops to prevent the breaking of the brittle straw by the wind. Wherever construction work is proceeding, and a wind of unusual force is forecast, builders and engineers make doubly secure that which is already constructed, instead of proceeding with outlying portions of the structure.
"In short, Mr. Tighe, there is scarcely a business in the country which would not be benefited by a close study of weather conditions. The difference between a careful man and a careless one is the difference between a man who thinks in advance and a man who does not think until some condition of grave difficulty is thrust upon him. Weather is, to this day, and will ever remain, one of the most potent factors in human welfare, and a man cannot plan for the weather in advance, unless he has a weather forecast."
The farmer brought his fist down on the table with a thump.
"Tell me, then," he said, "since all the big business firms in the country use the Weather Bureau so completely, why do people laugh at the Weather Man?"
"That's very simply answered," the Forecaster replied, "it's because every one is not a wide-awake business firm. Ask a commission merchant, whose business depends upon his receiving his produce in good condition, whether the Weather Bureau warnings are profitable or no? Ask a fruit merchant, who knows that a difference of twenty degrees in temperature during shipment spells either profit or disaster! Ask a shipowner on the Great Lakes or the captain of a trading schooner in the Gulf! These men will tell you that their lives and their fortunes hang on their careful understanding of the weather. But if you ask some one who merely wants to know whether or not to wear new clothes or whether it will be safe to have a picnic on a certain afternoon—then, indeed, unless the weather is of the particular pattern that they prefer, you are apt to hear that 'the Weather Man is always wrong.'
"There's another reason, too," he admitted, "and that is that local conditions may differ from regional conditions. I've shown you that there's a cold wave coming, and that over this section the temperature may drop twenty degrees. But suppose your thermometer, Mr. Tighe, is near the slope of a hill, which starts a small current of air moving, just enough to keep the air well mixed, then your thermometer may not register a fall of more than ten degrees, and you'll accuse me of being an alarmist. None the less, in a valley a quarter of a mile from your thermometer, the temperature may have dropped twenty-five degrees and for a hundred miles in every direction, the average temperature will be equally low.
"Suppose, over a section as large as the Gulf States, or New England, the Weather Bureau announces a forecast of showers. There might be stretches of fifty miles square in which never a drop of rain fell, and people in a hundred towns would take their umbrellas needlessly. Yet, in six hundred other towns in that region, there would be showers.
