Pursue this course, or one similar to it, for a few months and we defy any girl to keep well. She may not yet break down altogether, but she will have lapsed from positive into negative health, and the merest straw may turn her negative health into actual bodily incapacity--which means the loss of work and wages to which we have referred. And is it to be wondered at? Our girl has been steadily withholding from Nature all those elements upon which she imperatively insists as the condition under which alone she will consent to carry on her work. Long-suffering she is, and ever eager to repair any neglect that has not been carried too far. Only return to the right path, and she busily sets to work to make good the ravages which have followed upon our ignorance or neglect of her laws. But it must be the right path. None other will do. She will not be cajoled into working with any other than her own simple tools. Our girls have withheld from her air, food, exercise--the three great factors of her powers--and have given for them miserable substitutes. Though kind, she cannot be put off with excuses. She is inexorable, and the same results will follow our neglect of her laws, whether it be due to a want of acquaintance with them or want of attention. It is as much, if not more, from these causes, then, that our girl has become ill than from the supposed overwork. Overwork might have been the immediate cause; that is to say, her collapse might have followed upon a little extra pressure or hurry of work; but the real cause will be found to lie in that steady neglect of the primary laws of health to which we have alluded, and upon which too much emphasis cannot be laid. Had it not been so, the fatigue engendered by an extra hour's work would have been set right by a good night's rest. And when our girl is ill, her recovery will depend upon the degree to which she is enabled to meet the demands of Nature. If she can have plenty of rest, peace of mind, fresh air, light, digestible, and nourishing food, sunshine, and genial surroundings, she will soon be herself again. But if our brave worker has not these indispensables, or has them in a chance, get-me-if-you-can sort of way, then she lingers on, and often rises from her couch but half cured, and plunges on again under the old conditions, until something occurs which some persons call "a chance," some by another name, which mercifully changes the current of her life for a while, or perhaps for a permanency.
