Microbes breed in fermentation, consequently, every particle of undigested food remaining in the stomach or intestines becomes an ideal nursery for their propagation. It has been demonstrated that food that has been subjected to the action of the gastric juice decomposes far more rapidly than that which has not--hence, with imperfect digestion, fermentation quickly takes place. If microbes are now introduced into the system, either by contact with sick persons, inhaling impure air in crowded public buildings, or breathing in the dust on ill-kept streets, there is danger ahead; for if the recipient is not in a sound, physical condition, the microbes (finding congenial lodgment), multiply with the most marvellous rapidity, permeating every portion of the tissue--causing, in fact, DECOMPOSITION WHILE STILL ALIVE.

Every particle of animal or vegetable matter, even if only a single grain in weight, by exposure to the air, _putrefies_, breeds, and attracts to itself thousands of microbes, and becomes a center of infection. Thus, in a piece of street dirt containing organic matter, we may find upon examination, the germs of typhoid fever, diphtheria, scarlet fever, or consumption. When this piece of dirt is dried by the sun and pulverized by horses’ hoofs and the wheels of vehicles, the particles of dirt are caught up by the wind, and sent whirling through the air, to be drawn into the lungs by those within reach. Of course, every one who breathes in the microbes of some particular disease does not catch it, or we should soon all be dead, but those who have not the resisting power of sound bodies to kill these germs, before they have time to set up their peculiar inflammation, are apt to realize the evil effects, a week, a month, or even a year afterwards.

It is evident then that to _cure_ disease we must get rid of all fermentation in the system, and thus prevent the further breeding of microbes; and to _prevent_ disease we must get the system into such a sound, healthy condition that disease germs cannot obtain a lodgment in it.

Now, this can only be accomplished by thoroughly cleansing the colon, and keeping it absolutely clean, thus preventing further contamination of the blood current--the fountain of life.
