The inevitable result is sound health and great capacity of enduring fatigue. A man like this does not sweat for a trifle, and seldom shows signs of distress, Returning to my winnowing simile—if you were to set fire on the one hand to pure wheat grain, and on the other to its chaff and straw, the latter would surely blaze up much the quicker; the grain would burn only gradually, without a blaze and not all at once; it would smoulder slowly and take much longer to consume. Well, disease or fatigue being similarly applied to this sort of body will not easily find weak spots, nor get the mastery of it lightly. Its interior is in good order, its exterior strongly fortified against such assaults, so that it gives neither admission nor entertainment to the destroying agencies of sun or frost. To any place that begins to weaken under toil comes an accession from the abundant internal héat collected and stored up against the day of need; it fills the vacancy, restores the vital force, and lengthens endurance to the utmost. Past exertion means not dissipation but increase of force, which can be fanned into fresh life.
