Jason flushed angrily.

"Oh, I know what ye mean," he snapped. "Ye think thar don't nothin' ail me, an' that jest fetchin' Dolly from the pasture did it all. But I know what them symptoms means; they mean heart disease, woman,—'cardiac failure,'—that's what 't is." Jason leaned back in his chair and drew a long breath. When he could remember his "book-learnin'" and give a high-sounding name to his complaint, his gratification was enhanced.

"Hm-m; mebbe 't is, Jason," retorted his wife; "but I'm a-thinkin' that when a man of your heft and years goes kitin' 'round a ten-acre lot at the tail of a fly-away colt, he'll have all that kind of heart disease he wants, an' still live ter die of somethin' else!" And Mehitable cheerfully banged the oven door after making sure that her biscuits were not getting too brown.

As it happened, however, there was really no chance for Jason's heart disease to develop, for that night he scratched his finger, which brought about the much more imminent danger of blood-poisoning—"toxemia," Jason said it was. For a time the whole household was upset, and Mehitable was kept trotting from morning till night with sponges, cloths, cotton, and bowls of curious-smelling liquids, while Jason discoursed on antiseptics, germs, bacteria, microbes, and bacilli.

The finger was nearly well when he suddenly discovered that, after all, the trouble might have been lock-jaw instead of blood-poisoning. He at once began studying the subject so that he might be prepared should the thing occur again. He was glad, later, that he had done so, for the Fourth of July and a toy pistol brought all his recently acquired knowledge into instant requisition.

"If it does come, it's 'most likely ter be fatal," he said excitedly to his wife, who was calmly bathing a slight graze on his hand. "An' ye want ter watch me," he added, catching up a book with his uninjured hand and turning to a much-thumbed page for reference. "Now, listen. Thar's diff'rent kinds of it. They're all 'te-ta-nus,' but ye got to watch out ter find out which kind 't is. If I shut my jaws up tight, it's 'lock-jaw.' If I bend backwards, it's 'o-pis-tho-to-nos.' If I bend forwards, it's 'em-pros-tho-to-nos'; an' if I bend ter one side, it's 'pleu-ro-tho-to-nos,'" he explained, pronouncing the long words after a fashion of his own. "Now, remember," he finished. "Like enough I shan't know enough ter tell which kind 't is myself, nor which way I am a-leanin'."

"No, of course not, dear," agreed Mehitable cheerfully; "an' I'll remember," she promised, as she trotted away with her salves and bowls and bandages.

For some days Jason "tried" his jaw at regular intervals, coming to the conclusion at last that fate once more was kind, and that "te-ta-nus" was to pass him by.

The summer ended and autumn came. Jason was glad that the cold weather was approaching. The heat had been trying. He had almost suffered a sunstroke, and twice a mosquito bite had given him much trouble—he had feared that he would die of malignant pustule. His relief at the coming of cool weather was short-lived, however, for one of the neighboring towns developed a smallpox scare, and as he discovered a slight rash soon after passing through the place, he thought best to submit to vaccination. He caught a bad cold, too, and was sure pneumonia was setting in—that is, he would have been sure, only his throat was so sore that he could not help thinking it might be diphtheria.

Realizing the seriousness of the situation, and determining to settle once for all the vexed question, he pored over his books in an exhaustive search for symptoms. It was then that he rushed into the presence of his wife one morning, his face drawn, his eyes wildly staring, and an open book in his shaking hand.
